"All in all, the results were interesting, to say the least. The 16-core, 32-thread Ryzen 9 5950X saw single-core-load CCD temperatures in the 90 °C department with the TEC solution disabled - which promptly dropped down to only 50 °C with the cryo cooler actually operating. With a game load, the 5959X achieved up to 5.050 GHz in single-cores on its automatic boost profile. The entire chip often boosted to 4.8 - 4.9 GHz on all cores at once (with variances between the CCDs) whilst under this cooling solution and workload. With the TEC operating in its unregulated mode - which means, with no considerations for CPU operating temperature and power usage for the cooling process - saw the Ryzen 9 5950X achieving 2 °C core temperature results, and boosted frequencies up to a staggering 5323 MHz on all cores - before crashing. An interesting piece of work which you catch on video after the break; one can rest assured that most PC cooling specialists are already working on their own TEC-based cooling solutions following Intel's achievement in this field."

Nice. I'd consider one for my Threaripper if they made one.

My only concern is that I'd also want one for the GPU, or the resultant hotter coolant from the hot side of the CPU TEC, will result in higher GPU temps.

To me TEC's are a, one in every block, or none at all type of technology because of this.

Either that, or this is the first real reason to run multiple separate loops on one system.

I watched a 15 minute ad today on YouTube from Linus tech Tips (an ad inserted within a unrelated video). He showed the Intel version of this. A 200W peltier inside an all in one heat block. Pretty cool video. Intel has software that specifically interacts with cooler to modulate it.

This is the Intel version modified to run with a AM4 mounting system.

He had to use an Intel system to control it.

From what I understand tec are extremely good until they become very bad with the heat output goes up a certain threshold, i.e. maybe more interesting for 5600-5800 or gaming than the 16 cores and up chips on serious work load.

Yep. They are capacity limited. If you exceed the capability of a TEC it goes from amazing to awful.

The manufacturer would have to select an appropriate TEC for the expected heat load from the CPU (or GPU) it is being designed for, which might be challenging considering the high TDP of some GPU's.

Someone needs to hit it with an oscope under different loads and develop some software so it can be used in other systems.

Well if it is handling a Intel 10900k oc to shit then a 5950x would be no problem.

Is a few extra degrees at the GPU actually going to matter for anything other than bragging rights? AFAIK under water modern designs will hit power limits well below thermal throttling points.

Well, the newest GPU I have messed with under water is my Pascal Titan X.

I have found boost clocks start to drop if I allow the core temp to exceed 40C under load.

Can't speak for anything newer than that.

In gaming (where 16 cores CPU are often quite underused), it crashed under serious workload like cinebench with the 5950x, it was already quite limit for the 10900k according to him.

What is old is new again. Used to run TECs on Intel EE chips back 12-13 years ago or so.

I remember having one about 10 years ago when a company brought a TEC CPU chiller to market, but I can't remember who it was. All I remember is that it was super niche and the whole thing was really loud.

Probably a Vigor Monsoon. I still have one sitting the storage room.

10? newbie

was doing it on pentium (p5) before pentium pro (p6) came out

Tupperware and fish tank pumps... bring back memories for you as well?

This implementation sounds absolutely fantastic, though. I look forward to seeing other companies copy the control concept.

Can't beat a swimming pool for a reservoir or just drip the whole thing in mineral oil.

Current TECs can't handle the larger CPUs; But I had the idea in my mind to make it work. Never seen any one do it anyways. Take a tower cooler with strait heatpipes, remove the fins, put water blocks on ether side of both pipes (4 water blocks, 4 TECs). Like a Noctua NH-D14, but not so spread out. Then again who would want to have a 1600watt power supply just to run their cooler. Might as well go phase change. Also need to be regulated to avoid freezing the wic.
