Hi all. Need some counseling here.
So this thing I have ongoing with new CPU AIO is really a strange one.
To the story then: Changed by Noctua D14 CPU cooler to a AIO, Arctic Freezer II 240. After the "maintenance", I started to see
bottleneck from power perspective. When running full load, I can't get full watts out from the card. Power is limited to ~127W while exercising any type of heavy GPU calculation. Tried with Precision X1, VF Curve tuner, Afterburner, 3Dmark and few others benchmark tools and games.
Now to the strange part; Did a clean install. DDU and Nvidia; Perfect! GPU working again perfectly, until I rebooted. Now the issue is back. Roughly 127W at peak, power consumption running on ~46 to 49% based on multiple monitoring tools. So I re-installed drivers etc. Power limit was gone and performance once again "as it was" with D14. Based on VF curve on Precision X1. At least for a moment. So launched Steam and WAIT, WHAT? With 3Dmark, back to bottleneck with half the juice I'm expecting. Ok now I'm lost.
Can't really tell what is happening. Something broken? Can't even figure out how to confirm. If GPU/PCIE doesn't work, PC wouldn't post right? Or if PSU/cables have broken, I would get BIOS post right? And since the issue is somewhat random, it's impossible to pinpoint to a certain component. 650W should be enough.
Anyhoo. Ideas? Really appreciated.
And to clarify; Yes, took almost everything off to clean the dust while removing D14 and mounting Arctic F. Top placement on AIO radiators, no issues with temps, airflow with excess pressure and yes, been building my personal PC's for the past 15 yrs. So didn't notice myself doing anything like screwing through CPU socket or something :)
