I found that increasing the pump RPM by 1000-1200RPM by running it at 19V dropped about 3-4C on the CPU core max temperatures and temperatures are more stable overall.
The only issue is that when I touched the pump cover I can feel the pump motor driver IC gets pretty toasty at this voltage. Turns out I can simply put a copper plate with some thermal paste on top and it stays only warm to the touch through the copper now. Hopefully now it won’t die lol.
I’ve done 19V AIOs before with the Thermalright Edge 360 to cool my 400W 11900K and that has been working for a year now. Also helped temps by quite a lot there. AIOs are really bottlenecked by pump flowrate instead of radiator or fans. I tried 19V boosted Thermalright B12-Extrem fans running at 4000RPM and it didn’t drop temps nearly as much.
Anyways this Xeon W-3175X is a real beast. You can see the powerdraw on HWINfo reading ~175W peak and ~150W average running AVX512 Y-cruncher at 4.0GHz. Since this CPU gets a SVID reading divider of 4x that means you multiply the reading by 4x. Which means it is consuming ~700W peak and ~600W average power just on the package alone.
After the VRM losses and PSU losses the PC alone is sucking 1kw from the wall lol. Y-cruncher is also not the heaviest load I can put on this thing. If I am running full AVX512 workloads like running LLM models, it can easily hit 1.2kw from the wall even with CPU only load lmao.
The aida64 numbers are also pretty decent considering this isn’t running overclocking binned DDR4 UDIMMs you find on regular PCs. This is running on 6x 32GB Samsung B-die ECC DDR4 2400 RDIMM sticks. Since it is B-die you can overclock the crap out of it and pump the voltage. I haven’t gone past 1.35v for now but it can probably go a little faster and tighter. Try and show me a modern Ryzen AM5 or Intel LGA1700 platform with similar Aida64 performance at 192GB of RAM haha.

Please put a small cooler on your cooler. Would be the best thing I’ve seen in a while.
Also cool project, pump bottleneck checks out. Makes you wonder why they won’t design them with higher rpm.

Lmao. Aio overclocking isn’t something I expected to read about today.
