Dancop Posted August 30, 2015 Share Posted August 30, 2015 (edited) Hey GUYS! I did a lot of testings the last weeks... Spent more than 150L of LN2, hopefully to help you guys, not doing the wrong TIM on your Skylake DIE My testsystem is: Asus M8G Kingston HyperX Predator 8GB 3300C16 @ 3000C11 Seasonic 1200W Platinum Intel skylake 6600K ES Der8auer BEAST as container for the CPU What have I done? I put all the following TIMs on the DIE of the CPU. On the Intel HS I always used Thermal Grizzly Kryonaut! TIMs I've used: Innovation Coling Diamand 7 Carat Prolimatech PK1 Prolimatech PK3 Thermal Grizzly Hydronaut Junpus DX-1 EK Ecotherm Gelid GC-Extreme Noctua NH-1 Thermal Grizzly Kryonaut Then I went into Windows 7 64bit with the following settings: 5200/5200 on the core/cahce Voltages: Vcore: 1,75V (just to be sure, to generate enough heat) VDIMM: 1.6V Core PLL: 1.8V DMI: 1.37V VCCIO: 1.3V PLL Termination: 1.6V Standby Voltage: 1.5V Bandwith: 6 Temperature measured with the ASUS Batmobile (OC-Panel 2) For each TIM I've tested it twice with de-mounting and renewing all the TIM! Then I did two several tests. Finding the "Crack-Point" in idle and on load (Cinebench R15)! The "Crack-Point", I call it Ice-Ball point, cause it sounds (it is truly hearable!!!) like the little Ice-Ball which you have to crack in Taiwanese menthol cigarettes, when the TIM reaches its lowest temperature, before it looses contact to the POT, IHS or DIE. For me it looks like it's a matter of bonding agent (I don't know the right expression in english! I mean the fluid, that makes the TIM more or less fluent). When this "bonding agent" gets too cold, then it starts to get hard and cracks because of the different coefficients of expansion between silicium and copper. You can reproduce cracks when you are on heavy load and the pot is very cold and your cpu crashes. Then the silicium turns from approximately minus 20 degrees to minus 160 within a milisecond! The copper from the pot and the IHS already has its typical size for this kind of temperature, but the silicium changes it right now, which makes it much smaller compared to the size it has while load! The most important thing is the follwing; mount your pot as tight as it goes! At least, that's what I found out! Now you wanna know which TIM is the best (I can only name the pastes I've tested, so if one is missing, let me know, or if you're a TIM vendor....send me!) Here ya go: Please guys, share your experiences...I hope we can find THE right TIM soon!!!! Right now it is Thermal Grizzly Kryonaut!

minicoopers Posted August 30, 2015 Share Posted August 30, 2015 Great test. Thanks for sharing Daniel Quote Link to comment Share on other sites More sharing options...
Crew Leeghoofd Posted August 30, 2015 Crew Share Posted August 30, 2015 We had the crack way earlier than -180. Depending on clock frequency/volts we could not even surpass -145°C before we lost it.... Ourt best temp region with Grizzly was between -125°C / -145°C max. If we lost contact best to torch till -40ish and then slowly build up the clocks/temp Quote Link to comment Share on other sites More sharing options...
Dancop Posted August 30, 2015 Author Share Posted August 30, 2015 That's what I meant with....as tight as it goes With 5 rounds of the screw...136 with 10 165 with 17 ( more is not possible) 185 Quote Link to comment Share on other sites More sharing options...
Crew Trouffman Posted August 30, 2015 Crew Share Posted August 30, 2015 GC-extreme and Kryonaut are way above the others Definetly a target product for overclockers it seems. Thanks for sharing Quote Link to comment Share on other sites More sharing options...
Dancop Posted August 30, 2015 Author Share Posted August 30, 2015 Indeed! OMG...3 people watching it within some minutes...seems to be interesting Quote Link to comment Share on other sites More sharing options...
Toolius Posted August 30, 2015 Share Posted August 30, 2015 Thank you soo much Daniel San This is a huge help for guys like me !! Also this i did not understand what you meant .. ?? That's what I meant with....as tight as it goesWith 5 rounds of the screw...136 with 10 165 with 17 ( more is not possible) 185 Is this the temps you could bench at with the amount of rotations on the screws ?

Dancop Posted August 30, 2015 Author Share Posted August 30, 2015 Exactly. ..beast mounting only Quote Link to comment Share on other sites More sharing options...
Toolius Posted August 30, 2015 Share Posted August 30, 2015 Thank you soo much One last question.. Did you use the springs or no need for them ? Thank you sooooo much for all the help !! Quote Link to comment Share on other sites More sharing options...
Dancop Posted August 30, 2015 Author Share Posted August 30, 2015 Sure...that's what I'm talking about! With the beast springs and the named rounds of the screws Quote Link to comment Share on other sites More sharing options...
BenchBros Posted August 30, 2015 Share Posted August 30, 2015 Thank you very much for these tests But what about heat transfer from DIE to HS? I mean... Do we really care about the best Temps, or the best clocks. Did you test highest clocks on fixed VCore or sth like this? Quote Link to comment Share on other sites More sharing options...
Dancop Posted August 30, 2015 Author Share Posted August 30, 2015 Yes I did...Except for PK1, Hydronaut and NH-1 They were too bad! max Clocks in R15 Kryonaut 6320 Diamant 6150 PK3 6100 DX1 6080 EK Ecotherm 6100 Gelid 6280 Quote Link to comment Share on other sites More sharing options...
Samsarulz Posted August 31, 2015 Share Posted August 31, 2015 Great to see a round up like this since Thermal Grizzly was released some days ago Would like to see more testing! Regards Quote Link to comment Share on other sites More sharing options...

Achill3uS Posted August 31, 2015 Share Posted August 31, 2015 very nice effort i guess not a big surprise anymore Grizzly is the best TIM on the market! Quote Link to comment Share on other sites More sharing options...
Wizerty Posted August 31, 2015 Share Posted August 31, 2015 That's what I meant with....as tight as it goesWith 5 rounds of the screw...136 with 10 165 with 17 ( more is not possible) 185 ... Did you use the springs or no need for them ? ... -> 17 rounds without spring.... that's tight indeed Thanks for sharing Quote Link to comment Share on other sites More sharing options...
tiborrr Posted September 6, 2015 Share Posted September 6, 2015 I guess our Ectotherm does well, considering I validated it to -50°C Good work Daniel! Quote Link to comment Share on other sites More sharing options...
Rauf Posted September 24, 2015 Share Posted September 24, 2015 How do you guys get the kryonaut to such low temps without cracking? Tried Z170 on LN2 for the first time today and got the crack at -145. This was with my Kingpin EE with supertight mount! Springs fully compressed. And they are quiet sturdy... Do you use a thin or a little thicker layer? Quote Link to comment Share on other sites More sharing options...
Crew Vivi Posted September 25, 2015 Crew Share Posted September 25, 2015 How do you guys get the kryonaut to such low temps without cracking? Tried Z170 on LN2 for the first time today and got the crack at -145. This was with my Kingpin EE with supertight mount! Springs fully compressed. And they are quiet sturdy... Do you use a thin or a little thicker layer? depends how aggressively you pour. you have to go super slowly. if you want to go over crack point you must have 1 degree increments past the "noisy" point of the pot. it also depends where you mount your probe and what equipment you use, maybe you are at -160 compared to other guys. So there are many factors. But for me to get no crack is very clean die and hs , then apply one line on the die, mount ihs, then one line on the ihs, mount pot with moderate settings, i dont like tight . Excellent thread and work daniel, awesome! Quote Link to comment Share on other sites More sharing options...
Dancop Posted September 25, 2015 Author Share Posted September 25, 2015 Thx! Exactly Vivi! Pouring is everything! Beast is very fast, but that's exactly what the pastes don't like. Be patient...slow...not aggressive Quote Link to comment Share on other sites More sharing options...
Guest barbonenet Posted September 25, 2015 Share Posted September 25, 2015 (edited) Sorry daniel....the original tim, cracks??? What was the max cb before delid??? Thanks bai Edited September 25, 2015 by barbonenet Quote Link to comment Share on other sites More sharing options...
Dancop Posted September 25, 2015 Author Share Posted September 25, 2015 Around 120... Quote Link to comment Share on other sites More sharing options...

Dancop Posted September 25, 2015 Author Share Posted September 25, 2015 Problem is, I only had original tim on my 6700k. My 6600k was delidded before I've done this test. So I thought it wouldn't fit into this test... Quote Link to comment Share on other sites More sharing options...
