Been running some benchmarks using the OCC. Results seem pretty fair. Is it normal to run a 5960x at -80C to -100C through multiple benchmarks at 5ghz with good stability? That's where I set it for the benchmarks I just submitted this evening. It seems like others are running benchmarks at lower temps (but maybe that's because of the temp swings of traditional LN2 cooling. When I ran the system at -128C at 5ghz it seemed less stable. Maybe something to do with the electrodynamics vs thermodynamics of the ultra cooled system in the purge case? I'm going to be posting some video of the OCC from set-up to benching in a few...

I could use some help and advice here peeps. I have been running some benchmarks on my 5960x cooled by the OCC Liquid Nitrogen chiller (you can see more about the chiller on my thread). The submissions seem to be going alright, but really it would be very helpful to get a some insight on the submissions and further tweaks I could use to help my scores. Could you take a second to view my profile and the submissions and then comment http://hwbot.org/user/lnlcooling/? Also, why did i go from Rookie league to Extreme league in a day?

Excellent!! So nice to see tools being engineered to solve such common needs! Great job der8auer! Let the industry grow!!!!!

Here is a new informational video from LnL about the OCC and the Purge Case. We hired a legit voice-over guy for the narration . . .. Actually that's just me - no pro to it. Stay tuned though actual pro results are coming to an HWBOT near you soon!

Just completed a new build with new enclosure. Looking good! Thought we’d have a little fun with a heat gun! We did run the OCC on our new 5960x and the results were fantastic. Ran 5.3 ghz and there was no temp swing during benchmarks (seriously, it gained 1 degree). But our pro colleague who is getting the OCC next week wants to break with the news with his video of his sweetness-5960x and verified results. LN2 vs 1700 watt heat gun!

The system is just regulating at -180C. This temp is from very close to the surface of the chip, but withing the wall of the chuck. So the actual surface in the mid-diameter of the chuck is likely lower. I have run the OCC a lot down at -186 t -190 on but I think at that point, the inner diameter of the chuck is closer to -196C -199C as the LN2 boiling slows considerably and there is less flow in the purge. (For the non-cryo-engineering: LN2 gets really calm as the temp drops down by -190C, whereas when the temp rises it begins boiling more and more furiously to the point of flashing - like what happens when you drip water into a frying pan, but at -80C rather than frying pan temps. So LN2 at -190C is literally calm, cool and collected!) It is set at four cores for the higher clock in the last vid. Could probably have gone higher clocks if I understood the correlation between voltages better. I was basically guessing and trying to get to 6.7 on 4 cores. Here is a little older vid of 8 cores at 5.7 ghz. The OCC holds it down fine. CPU-z shows clocks and cores at 1:3.. Fast forward to 4:23 to see the OCC running during benchmark.

https://www.youtube.com/embed/7YZpW0h9z4o This is the latest video of the OCC-HC cooling the FX8350 maintaining temp at -180C. We'll be moving up to the 5960x in the next week or so. The OCC will be maintaining a set point between -130c and -140c (wherever we set it). That's the exciting thing about the OCC wherever the set point is, there the temp is maintained. No thinking or guessing about pouring, or even the need for multi-person teams to cool vs overclock. Not to mention being able to have the sickest, coldest driest gaming rig!

Yeah! Thank you for the recognition! It's only getting better.

Yeah a ton of hours. But even more belief that we can do it. Thanks for the props! We'll be trying to make them accessible to as many people as possible. What is not being missed though is the capability and quality. We've made some design changes and enlarged the chuck a little and we're just about ready to roll. So stay tuned as the curtain is about to go up on some sick revelations!

Yeah, I can see where you're coming from. There's some surprise news about to be broke out though. What if someone ends up breaking records? What if the control afforded by the investment wound up putting people in a whole new league? Remember on OC'ers they said it couldn't hold the fx... then... well that's not a question anymore. But what about the 5960x? I have one now brand new and dying to go cold... But someone else will be breaking the OCC out on the 5960x first. It's about to get a little more exciting . . .

Shucks Thanks! Can't wait to see the developments from the pros and novices!

That's awesome! If you could be more specific. Gotta remember, I am still stuck in the 90's with gaming. The Nintendo 64 was the last console I owned. That's just being nakedly honest. The high overclocks side we have taken care of as we have a pro ordering an OCC tomorrow. But I need to know where to start with "counter-strike" and MOBA's."

Well thank you so much! We will be seeing a lot more very soon!!

yeah, the chuck might be fine, but the rest of the machine would be likely wrecked. The materials used for the OCC are designed for LN2 temps which are like 100C higher than LHe. I'm sure a build would be possible, but rediculously expensive. The LN2 hose alone is a huge cost. I can't imagine what LHe hose would be. Just R&D would break the bank!

Yes one OCC per chuck. It's all one unit. There are two different types of OCC's the HC (heat control - especially good for CB and CBB and CO (cold only - cheaper because of a different controller - yet looks the same - and no heaters. The heaters enable the OCC to ramp temperature (warm the chuck up) and maintain setpoints. Especially useful with the CB and CBB chips.

LHe is for the crazies! Doesn't it make everyone's voices in the room sound squeaky? Maybe if you did LHe in the purge case it would float like a balloon... dreamy! No LN2 on the island yet?

I assume that by SLI you mean multiple GPU's with slim side mounted chucks. We are working on the SLI chuck configuration but for the moment we only have the configuration you are seeing. Specialized GPU and RAM chucks are coming very very soon. In the present configuration, the GPU OCC is a matter of using the same OCC with the GPU mount. Purge cases can be outfitted with as many ports as needed for OCC umbilicals. So yes open air or dry case!

Instead of three heads, you run three OCC's. Presently, the same design for the CPU will work for GPU. We will have a RAM chuck for the OCC within the next month or so. The OCC can be run in open air, its just a matter of insulation which I assume the xoc community is already doing. With 1 OCC per component, you can controll temps separately. I rent my 220 psi dewar for about $1.50 per day plus the cost of LN2. I don't know how much rent is in your area, but that is the way to go, and pretty cheap as opposed to buying a dewar. And when I rent one pick up and delivery is free. I just connect the OCC and go! Edit: The 3 OCC's are run off of 1 Dewar.

Well, I don't think discussing sales is allowed in general forum. Just functionality. But google us for more info.

Yo Slpave this is the guy from a couple years ago who was working on this! Kal-El connected me and you helped with some wattage and size info. This is the finished product! (with the exception that our final chuck will be about 1-2mm wider). Usage: I've ran full blast (-180C) on a 160l Dewar for somewhere near 40-50 hours. But that is max cold - wide open on the FX8350. I can imagine that the higher temp (-140 cb) 5960x would use less LN2 to regulate. I use a 220 psi dewar bled down to 65 psi. I just added a 65 psi pressure release valve and bled off the excess. Have you seen our website and videos? We have come so far since we last comm'd. I'd love to see one of these in your hands! PM me!

no no v readouts

Gotta be honest with you... I don't know what v-readouts are. I know the GPU temp didn't readout under 0C. But the mobo read down to -59C during extended use. The OCC cools the CPU or GPU with liquid nitrogen while the purge kit cools everything else with gaseous nitrogen and purges out all moisture from the case. Basically the case is an environmental chamber cooled by the gaseous nitrogen from the purge kit :-)

Hi folks I have had several suggestions from OCN, OCA, OC'ers, and Xtrmsys to join up here and share about the OCC. Gunslinger, Splave and Roman are welcome to chime in. The OCC is a controlled LN2 chiller which can be set at any temperature down to LN2 limits (around 180-196C depending on load) and maintain the set temp (or the set-point) by the implementation of LN2 (and heat with the OCC-HC). Also the Zero Ice purge case provides the perfect environment, zero ice, no insulation needed. Our L&L Cooling youtube channel has several videos of the OCC working at several different temps. In these videos I overclock to the best of my ability with the OCC maintaining temps from -23C to -180C (roughly). There's a lot of info on forums, so I suggest doing a little googling to find out more. We are going to be setting some records soon! Here is the latest vid of 6.3 ghz on the FX8350 (keep in mind I am new to overclocking):
