Hi Everyone
I've run into issue with my new build which is quite annoying, hoping for some advice here.
I finished my new build/loop about a month ago, everything seemed fine at first but I've noticed random crashes in few games, mainly in Indiana Jones, Anno 117 Demo and Broken Arrow.
Crash is always the same, black screen I can hear the game/sound in the background but can't do anything apart from shutting down, it does not recover.
In Windows log nvlddmkm error Event ID 14 flowed by 152.
At first I thought it was software issue but after wasting ton of time with drivers, settings, updates, windows ect, you name it I've tried it i found that the issue is with hardware/power delivery.
When my 5090 has waterblock on (Alphacool Core) temperatures are great, generally 50 to 60C roughly, maybe few degrees more but never saw more than 65 on either GPU or memory.
however when I run 3D Mark or any game for that matter and watch power draw it only draws full power for a moment, during first minute or so it goes to ~ 575W but gradually drops from there.
I made bunch of tests using HWinfo and GPUZ and I can see in the logs how TDP gradually drops from 100% down to # 78 ish
In 3DMark this will go up and down but I tried resting on static scene eg specific place in game and same thing happens and eventually it crashes.
Now here's a kicker, when I put the stock cooler back on everything is fine, card is much hotter tops out at 80/82C but still draws full power, 3DMark gets higher score and most importantly zero crashes in games.
I've been going back and forth with WB and stock cooler, changed paste, thermal pads etc but same thing, stock cooler runs hotter but works fine and with WB installed I get power limiting and crashes.
I have noticed that in GPU Z card runs in thrm limit in PerfCapReason, when this happens I can see drop in power in logs but GPU/memory are still sitting at circa 55C so what is overheating ?
Neither GPU Z or HWInfo are showing any other temp readings.
No idea why is this happening, WB is correctly installed I've been doing WC builds for 10 years and lets be honest it's not that hard to install a WB.
What could be causing this ? this is my first Alphacool block I used mainly EK before and never had this problem.
Could this be some flaw in WB design or maybe it's my setup ?
Perhaps WB is heating up because I have 420 rad directly below ?
I'm including screenshots, GPU Z with thrm redout, this was during 3DMArk stress test with WB on, never happens with stock cooler and my setup/airflow.
Second GPU Z screenshot is during 20 loops 3D Mark stress test with stock cooler, solid green line no limits other than power.
For now I'm back on stock cooler, considering buying Bykski WB but not sure tbh
EDIT: Forgot to mention that I tried same testing with a different PSU/cables and results are same.
