Hi,
I have an Hdplex H5 that I've modified with additional heat pipes and connected to cooler mounts, just a personal project trying to get more passive cooling power. My prior experience is building a Streacom DB4, which has been running nicely for a year now, and I just like the idea of passive cooling. I'm having a problem with higher wattages causing apparent thermal throttling before even reaching 90c, and I can't figure out what is happening.
This H5 as I've modified it steadily dissipates about 115 watts @87c running Cinebench with fully saturated heatsinks. But if I run the test again when it's hot, or increase my wattage, it'll run normally for a few minutes and then the power levels jump around, 65, 75, then boost back to limits for a few seconds. Using HWMonitor to watch, numbers more or less match Throttlestop's temps. It is also reporting temps in the 80's for CPUTIN and TMPIN3 under load, equal to CPU temp. This all happens with or without voltage offset. Pl1 115w, PL2 125w, Tau 10 seconds.
Most info I find always has to do with other cooling systems so it's been really hard to troubleshoot problems, help solving this would be much appreciated. It's probably something simple I don't understand.
Hardware:
I7 10700k
Asrock Phantom z490 atx
Kingston Fury 16gb 3200
Samsung 970 Evo 250gb
Silverstone Nightjar 450w
