Possible VRM overheating issues and recommendations
Possible VRM overheating issues and recommendations
Hello, I just upgraded my system to the current specs:
Case: NZXT H700i
CPU: 8700k
MB: ASUS Maximus X Code
RAM: 32GB Corsair Dominator Platinum @3200
GPU: ASUS Strix 1080ti
Cooler: Kraken x62
I have just delided my cpu and get get a potentially stable overclock of 5ghz at 1.35v at max temp of 75 degees C (so far). But I have noticed that after about 10-20 seconds into AIDA 64 or Realbench the clock will drop as far as 3400ghz. So far I have tried lowering the the overclock to 4.8 at 1.295v with a max temp around 60-62 degrees but about 30 seconds in it will drop to 4 ghz or lower. After reading around I'm assuming the culprit is the VRM overheating and throttling the speed. I'm currently running a fan setup of intake from the top and back with a push pull config radiator exhausting from the front and i have been testing with covers off to improve airflow.
I'm currently looking on solutions for better cooling or if this is an entirely different issue all together. My first idea was to remove the Plastic armor from around the vrm heatsink and/or add a fan somehow pushing air directly onto the VRM.
Any suggestions on this issue would be greatly appreciated, thank you.
Remove the side panel from the case and direct a desk fan toward it. If this addresses a motherboard overheating issue, it should help. Afterward, consider implementing a more lasting fix.
I'm not sure if the VRMs are overheating. These advanced ASUS Z370 boards feature efficient modern VRM design. Only slight airflow is needed. I think feeding the CPU 1.35v isn't enough to cause significant issues. They're usually safe for normal use up to around 100°C, though reviews on my Maximus X Hero suggest it only reaches about 60°C during overclocking.
Sorry I was away at a friend's bachelor party. I've just been working with the LLC and voltage, using my RAM on their XMP profile.
