UPDATE: TEST 2015 HERE Extreme-Overclockers are always trying to achieve the highest scores possible. No matter if CPU, GPU, mainboard or memory - everything has to run perfect in order to set up new records. The latest generation of Core i7 - Ivy Bridge - scales brilliantly on deep cold. Without cold bug the CPUs are limited by the pot and thermal compound. I will test 26 different thermal compounds in the following test to see how they perform with air cooling and liquid nitrogen.

Caseking was the most important as the provided the most products to me. Thanks a lot for that! I also received some samples directly from vendors. Thanks to Akasa, Alpenföhn, Coolink, Noctua, Alphacool respectively Aquatuning, der8auer ECC, JunPus, Dimastech and Prolimatech. Setup and description: TheoryI'm sure you guys already know why we have to use thermal paste. But just in case if there are some new members out there, I will explain why you need thermal paste. So what is thermal paste and why do we need to use it? Let's take a look on this simplified image first. You can see a cut image of a CPU and the cooler on top. Greatly enlarged you will notice that the surface of CPU IHS and cooler are pretty much rough even though it looks very flat with the naked eye. The spaces between CPU and cooler have to be filled with thermal paste to improve the thermal conductivity. That's why the thermal pastes are liquid and ideally never dry out. Most vendors guarantee about 2-5 years of usage between CPU and cooler. After this time you should change your thermal paste in case you still have your system after this time The majority of the thermal pastes are made of different silicones, oils and additives like silver, aluminum, ceramic or diamonds to transfer the heat. Unless other specified the thermal pastes have no electrical conductivity. This applies to all thermal pastes in this test. Setup For the first test I'm using a i7-3770K @ 4,0 GHz and 1,20 vCore cooled by a Scythe Katana 2 at 100 % fan-speed. To stress the CPU I'm using the tool CoreDamage. I'm running CoreDamage for about 15 minutes until the temperature is not changing anymore. Two thermal probes fixed on the CPU IHS and the base of the cooler are used to measure the temperature. As measurement value I'm using the delta-temperature between CPU-IHS and the cooler base. Most thermal pastes differ only by few 0,1 °C so measuring the absolute temperature with changing ambient temperatures would crash the complete test. Using the delta-temperature I'm eliminating this source of error. I'm doing each test with each thermal paste three times to exclude mounting issues of the cooler. After each test the CPU and cooler are cleaned using alcohol to remove all residues. For the second test I'm using the new der8auer Fusion rev 3.1 CPU container and liquid nitrogen. The container is cooling down the same i7-3770K which is now clocked at 5000 MHz @ 1,45 Volt to -50°C. Again I'm running CoreDamage to stress the CPU. During the test I keep the CPU as close to -50,0°C as possible. After few minutes if the temperature is not changing anymore I note down the temperature. The last test is to cool down the CPU to -150°C which is still running at 5000 MHz but on 1,50 Volt to give a little more load on the CPU and produce more heat. I'm again mounting the pot twice to eliminate measurement errors. If both measurements differ too much e.g. by 3,0 K I'm doing a third test and use the two measurements which are closest to each other. How to apply thermal paste and mounting pressure Whereas there are a lot of different ways to apply the thermal paste one thing is clear: the mounting pressure has to stay the same during the test to have consistent results. That's why I'm using the Scythe Katana 2 with Intel Push-Pins for the first test. It's a little more difficult to mount the pot exactly the same but Stummerwinter had a good idea here which I've seen few months ago as he mounted his pot. I'm using 4 springs which all have a normal length of 16,0 mm. Tightening the thumb screws I'm using a sliding caliper to measure the length of the springs until all have the tightened length of 12,2 mm. Applying the thermal paste you have to pay attention not to apply too much. This could have a negative influence on the cooling performance. Still you have to use enough to fill all gaps between CPU and cooler. That's why I'm using a thermal paste applicator to have a very thin layer covering the whole CPU. Setup: GA-Z77X-UP5 TH i7-3770K 2 x 2 GB G.Skill Pi 2400 CL9 LEPA 1600 W PSU Scythe Katana 2 (Test 1) der8auer Fusion CPU-Container (Test 2 and 3) Thermal compounds in detail: At the end of this test you will find a huge table including all the technical information and test results. That's why I will not explain the technical details of each thermal paste here. Alpenföhn Schneekanone Alpenföhn is a well-known manufacturer of cooling components and provides the first thermal paste of the test. Even though the tube is quite big the content is only 1,5 g. I prefer bigger tubes as they are easier to handle so this is a positive aspect. The packaging is very well designed and provides all technical information including the manual on the back. Included in the delivery you can also find an applicator. Coolink Chillaramic Coolink's Chillaramic straight attracts attention due to the nice packaging. The manufacturer promotes this product to be very good for lower temperatures and the use with Single Stages. An applicator or manual are not included unfortunately Noctua NT-H1 The Austrian cooler manufacturer Noctua provided the NT-H1 for this test. Compared to most of the other thermal pastes this product is very well packed and you can easily open the packaging. I'm not a friend of blister packaging You can find all important technical information on the back and a nice manual. Noctua says it's enough to place a little drop in the middle of the CPU and therefore does not include an applicator. Alphacool Silver Grease Alphacool provides a quite huge tube with 30 g which is the second biggest in this test. Therefore it's pretty good to use if you're changing the cooler a lot and don't need the best performance all the time. 32 Cent per Gramm is one of the cheapest products here. Additional stuff like manual, packaging or applicator is not included. Gelid GC-Extreme Gelid is very well known for the GC-Extreme using extreme cooling methods. The tube which contents 3,5 gram is one of the more expensive products and comes along in a blister packaging which is quite hard to open. Included in the delivery you find an applicator and all important technical details on the back. Zalman ZM-STG1 I'm sure you all know Zalman for their air- and water cooling solutions. The ZM-STG1 is a pretty interesting product which differs from the normal thermal pastes. It looks like a nail varnish and can be applied using a small brush which is fixed inside the top. Due to the low viscosity of this product you have to apply the thermal paste on both CPU and cooler. Revoltec Thermal Grease Nano Similar to Zalman's ZM-STG1, Revoltec's Thermal Grease Nano comes along in a small glass bottle and stands out of the test field. It's very easy to apply but is packed in a blister packaging. You can find technical details and a short manual on the back. JunPus D9000 JunPus is a quite unknown manufacturer from Taiwan. D9000 is the first product out of two in this test. It is very well packed and you can find all important technical details on the back including some nice charts. Included in the delivery you find an applicator. JunPus DX1 DX1 is the second product from JunPus. Packaging and content of delivery are same to the D9000. Xigmatek PTI-G3606 Xigmatek is a well-known cooler producer and provided two products for this test. The PTI-G3606 comes along with an applicator and a nicely designed packaging which is also quite hard to open. Xigmatek PTI-G4512 The PTI-G4512 is the high end product of Xigmatek and has a slightly higher performance than the PTI-G3606. Packaging and content of delivery are pretty equal to the PTI-G3606. All important information is printed on the back of the packaging. Cooler Master Value V1 The famous case producer Cooler Master also provides two products for this test. Value V1 is the midrange product which is packed in a blister packaging. On the back you can find technical details. Included in the delivery you find an applicator. Cooler Master Essentials E1 Essentials E1 is Cooler Masters high end product which is shipped in the same packaging like the V1. The E1 has one interesting feature, though: a cleaning cloth to remove old thermal paste. Like the V1 the E1 also has an applicator included. Dimastech HTX EE We all know Dimastech for his cool and helpful Bench Tables made in Italy. HTX EE is Dimas first thermal paste and comes along with an applicator and a well-designed packaging. I would have opted for something different than blister packaging. Dimastech Thermal Compound For testers with a high consumption of thermal pastes Dimastech offers a big box with 60 g content - the biggest in this test. Included you find two applicators Prolimatech PK-1 PK-1 is the entrance product of Prolimatech which is well known for its cooling solutions like the MK-13. Prolimatech offers the best packaging of all products. Very easy to open, well designed and very detailed technical information including the ingredients. An applicator is also included. Prolimatech PK-2 PK-2 is the midrange product has a higher performance than the PK-1. Prolimatech PK-3 PK-3 is Prolimatechs high end product and available in different sizes like the other thermal pastes of Prolimatech. Akasa 455 Akasa 455 is the smallest product in this test. Technical information is printed on the tube itself - a manual is missing though. Akasa 460 Akasa 460 is a midrange product of the Taiwanese cooler manufacturer. You can find all necessary information on the packaging even though it's quite hard to open. Included in the delivery you can find a multi-language manual and an applicator. Akasa 5022 5022 is the high-end product of Akasa and the packaging is pretty much equal to the Akasa 460, although the performance is higher. Arctic Silver 5 Artic Silver 5 is one of the oldest products in this test and has been on the market for quite a long time. The 3,5 g tube gets delivered without any packaging, manual or applicator. Arctic Céramique 2 Same as the Arctic Silver 5 the Céramique 2 comes along without any additional stuff. It has been used by a lot of different extreme overclockers in the past years and is a kind of classic product to me. Arctic MX-2 Arctic - don't mess up with Arctic Silver - provided two products for this test. The MX-2 is the cheaper version and comes along in a blister packaging. You can find all important information on the back of the product. The hazard symbol on the back should actually not disturb you as this applies for all pastes in this test. Arctic MX-4 MX-4 is the high-end product of Arctic and like the MX-2 available in different sizes. Except for ingredients and performance both products are pretty much equal. Amasan T12 Amasan T12 is a very cheap industrial product which I used over the past years for quick tests and therefore I'm including it into this test. Test 1: Air cooling Test 2: LN2 at -50°C Test 2: LN2 at -150°C Evaluation: Testable: Click to enlarge Evaluation of the test results After changing the cooler and applying the thermal pastes about 150 times and 80 hours of work - let's go over to the conclusion. Basically there are no bad thermal pastes - it just depends on what you are using it for and your expectations. There is no problem to use all of these products for 24/7 systems. Although you might be ending up with relatively cheap 70 EUR air- or water cooler, don***8217;t save on other parts of your cooling configuration. So which thermal paste for which application? Normal 24/7 Gaming- or Office systems:You can use all products here without any problems. Cheap products like the Cooler Master IC Value V1 or the Akasa 455 are enough here. Demanding gaming setups incl. overclocking Overclocker and gamer with high-end setups should spend few euros on the best thermal paste. You can easily gain 2-3°C upgrading from cheap products. I recommend: Gelid Extreme, JunPus D9000, Noctua NT-H1, Prolimatech PK-3, Akasa 5022, Artic MX-4, Cooler Master IC Essentials E1, Xigmatek PTI-G4512 and Alpenföhn Schneekanone. Extreme-Overclocker at -50°C (e.g. DICE or Single Stage) As you will be pretty limited by the temperature you should use one of the top thermal pastes to get the maximum out of your system. Good products are: JunPus D9000, Prolimatech PK-3, Alpenföhn Schneekanone, Noctua NT-H1, JunPus DX1 and Dimastech HTX EE. Extreme-Overclocker at -150°C and lower (Liquid Nitrogen!) - the supreme discipline Especially using cold bug free hardware like the Ivy Bridge CPU you should only use the best products available. I'm recommending Gelid Extreme and D9000 from JunPus. Awards Let's start with the best products of this test. Both JunPus D9000 and Gelid GC-Extreme are great products and reach the lowest temperatures possible. Both products come along with applicators but I prefer the packaging of the D9000 however it's a little harder to apply than the GC-Extreme. For the great performance both products receive the GOLDEN SYRINGE award. Alpenföhn Schneekanone, Prolimatech PK-3 and Noctua NT-H1 also have a pretty solid performance and therefore receive the SILVER SYRINGE award. Alpenföhn's Schneekanone means snow cannon in English which pretty much applies to its performance. It's quite expensive but the performance is good even on very low temperatures. The content of the tube is quite low but this can be good if you are using it just for one system. Prolimatech PK-3 is a solid product for air cooling and deep temperatures up to -50°C with a great packaging. Noctua***8217;s NT-H1 convinced me in all three categories and the packaging is also very well designed. Both 24/7 overclockers and extreme-overclockers can use this product without compunction. Cooler Master IC Essentials E1 offers a great price/performance. The cleaning cloth which is included in the delivery is a very useful tool and I hope other manufacturers will add this to their products. Akasa 5022 also offers a very good performance in all three tests and I can recommend this products for air- and water cooling as well as for 24/7 overclocking. JunPus DX-1 is also very interesting for 24/7 overclocking and extreme overclocking at temperatures of about -50°C. Taking a closer look on the test table you will notice that this product has the highest thermal conductivity with 16 W/(m*k) even though it did not achieve the best temperatures in this test. According to JunPus the DX-1 has a very long burn in time and will evolve the high performance after a few days of usage. Due to lack of time I could not test this unfortunately.

How did you do it? Glued IHS back on?

Why? results?

Good idea Will propably send some stuff over then. Like IMOG guessed the threaded rods are protected inside these pipes for the shipping btw: the boxes on the right side are the packaging of the mounting plates.

Couln't fit all on the picture but oh well

POM is a very strong material. Usually it's no problem to use it on -196°C if you calculate it corretly. That's why I've been using it as mounting material for years now.

Thanks POM is a semi-crystalline plastic which means it's always non-transparent It's only available in different colours - mostly black or white (natural). Only amorphous plastics are transparent. Thx guys One day I'll make a single purple unit just for you Thanks! I'll bring at least one to Computex. Have to check the weight of my luggage - maybe I can bring few more You're welcome Have fun with these units! I always include a 8ECC sticker in the orders No "powered by der8auer" stickers yet =) Thanks - appreciate that

Sweet mods! Thanks for sharing PJ.

Thx guys

hardware pron at its maximum

Thanks my friends One day I'll make a complete purple pot just for you

Hey guys I've been working a lot on my new CPU container and I'm happy that I can present it to you now. The basic structure is pretty similar to the rev 3.0 but with some major improvements. Fusion rev 3.1 Improvements: Higher copper part with more weight Deeper structure and chamber connections Smaler temperature hole (community wish ) New way of nickle plating with 7 times thinner layer for better heat transfer Aluminium tops anodized in different colours Aluminium mountings anodized in different colours LT Edition with POM top and POM mounting for less condensation water and less weight. In addition you need less LN2 to cool down the pot New backplate made of black POM New packaging All pots are 100% leak proof and tested with water, acetone, alcohol and LN2 But let's have a look at the pictures Click on the thumbnails to zoom in. Structure Base Pot with different tops - all anodized aluminium LT Edition with black POM top All together Red Edition Black mounted on M5E Red Blue Green LT Edition Black

Count me in

Wow! Nice pictures Thanks for sharing!

Very well done

done. Is there any kind of special registration I need to do to have access everywhere like on CeBIT?

This gonna be awesome

Lie http://hwbot.org/submission/2266474_der8auer_3dmark03_geforce_8800_gts_512_mb_71773_marks Why ban 4-Way SLI CF scores from XOC? How many are there even? 5? That will change nothing. ES are already banned from XOC so that's fine. I don't even see what and why you want to change in the XOC league. Apart from the old Pro-OC-League it's possible for everybody to get into top 10 without high-end hardware. You can buy a crap 6,3 GHz 3770K and use it for all the cards and you will be fine. No highly binned hardware needed. OC will always be about money. If you can't afford the latest CPU and GPU - well that's life. You can't expect to be first without invensting money. It's just impossible. I bought 2 x 3770Ks myself and both are about average. I'm not getting any highly binned CPUs from vendors and still made it into top 10 two weeks ago. Just by benching a lot of old cards and investing a lot in LN2. I'm spending about 300-400 EUR per month on LN2 at the moment. It's absolutely no problem for me to buy few mainboards as they cost like 200-300 EUR. Refusing the support by vendors wouldn't change my ranking at all. Pushing people like me into pro-oc is just a bad joke.

Cool Glad that you finally got it Hope you didn't miss the haribo I put into the parcel haha.

I'm one of the "semi-supported" guys Massman talking about. I'm getting support by Gigabyte and sometimes by ASUS. So far I got 6 Mainboards within 6 years of extreme overclocking. An average of 1 board per year. Compared to what I pay for LN2, CPUs and GPUs that's just drop in the bucket. To compare me with guys like Vince is just a bad joke. He has full access to 3770Ks and Titans as much as he wants. So I should compete with him? no thank you About the XOC League: The argument that you need sponsored or highly binned CPUs actually doesnt count here. You can easily get into top ten without using latest gen hardware. You can use a Sandy Bridge setup which is quite cheap by now and use older cards like 8600 GT or 8800 GT which give maximum points. ´ Another approach is to bench old CPUs like E8500, E6600, Q6600 or whatever. Get cheap CPUs at ebay and bin them -> bam 50 points per benchmark and you'll be top 20 or top 10 if you're willing to spend enough time for it. Just 3 examples: TaPaKaH, SteveRo or knopflerbruce. Non of them has a 3770K submission in the global or hardware points and still they are ranked in top 20 and even top 10. So everybody who is complaining about latest and binned is either a very bad overclocker or just has absolutely no clue how you earn points on the bot. XOC is the most flexible league here. You can bench whatever you want and can make it to top ten. Whether it's PCMark05, wPrime with big server setups, old GPUs, old CPUs or latest hardware. Taking away the latest hardware for XOC is a very bad idea. Who are the people complaining? Just curious.

and don't run all the subtests. Only Game tests

and use 169.21 driver

The question is whether the correct MHz is needed to have a valid result? I'm not realy a fan of specific rules for each hardware. This just makes the bot even more complicated and as long as the result is fine I don't think it's a must to have the correct MHz.

Nice pics here
