i9 14900K Running Hot Even After Some Pretty Aggressive Undervolting On ASUS Z790-A MOBO

[MaJesTiiCc]

I recently bought and built a new pc with an ASUS Z790-A MOBO, i9 14900K, Suprim 4090 Liquid, DDR5 RAM, a DeepCool LT720 Premium Liquid CPU Cooler (360mm) and x10 Corsair fans. Ive spent the last two weeks doing research and everything I can do get my temperatures under control. At this point I am running at 253W, 307A and all recommended Intel Limit as well as a -0.090 offset but my temps still reach 85C-90C when gaming no matter what Ive tried. Ive also turned off MCE, AI Overclock and Enabled all Limits. Could it simply be that I have a bad CPU and just need to get a replacement before it's too late or what could be my issue. Im genuinely at a loss and getting unimaginably discouraged. Thanks for any type of response or feedback.

Hello MaJesTiiCc

Have you tried turning up the fans on your cpu cooler?

What I would do is install HWinfo. With it open, play a game and see what the maximum cpu voltage is going to. This can give you an idea if the voltage is too high or if possibly the cooler isn't making good contact.

Vcore = CPU Voltage

Hi,

1. If all limits are enforced and MCE is disabled, the supplied VID is per Intel's hard fused voltage frequency curve. This is different for every CPU; some may be considerably higher than others.

2. It sounds like you may benefit from a contact frame if you've already ensured that the cooler is correctly mounted. Whilst you're checking HWINFO, inspect the pump speed to ensure it's functioning and correctly installed.

Yeah the issue was that my fans werent running at full speed. Bad Corsair fan commander. Thanks for the help.

It depends what game i have i9 14900k and 13900k and they are pretty much same but my sample 14th gen i 7C hotter than 13th gen if you play the finals game its normal spikes up to 85C on UV  if not like light game .. WRONG mouting it can't be 90C post how much wattage CPU is eating if its 100-120W and 90C wrong.. a lot.

If it is 160-180w and 80Cish .. pretty normal
