overclocking temps

[Bush Badger]

Just had to redo my overclock, 8700k at 5GHZ 1.310v. I have never seen it spike to 90+c before not to mention its being cooled by the kraken X72 AIO. is that normal? Also I think i used Arctic silver as I couldnt get my hands on any thermal grizzly.

is your processor delided?
if it isn't you could do that to get better thermal headroom.

if it is you should check your application of thermal paste on the cpu

In my oppinion, it is far too hot for a daily oc

I forgot to mention things were decent in the mid 60-70s while I was on 4.9GHZ once i bumped it to 5GHZ things started to go wrong

did you change the voltage when you increased your oc?

yeah I definitely did, it went higher. the OC is really unstable so I am trying 1.330v for a 5GHZ OC

[Devryd]

if you increase the voltage, your cpu will draw more power. More power means more heat, which means it gets hotter, if you don't step up your cooling

Intel CPUs also have the problem of having thermal paste between the CPU die and the heat spreader.

if you delid your CPU and then replace the thermal paste with liquid metal, you will get temps that are at least 10°C lower.

if you don't want to delid your cpu you should step down your oc or get a even stronger cooler

I totally agree with the delid part but a 360mm AIO is not strong enough? Also it seems that only Prime 95 will make it reach 90+ games and what not are fine sitting at 60c ish

[Devryd]

prime95 is the worst case scenario.
But my overclocked system doesn't get above 80 under prime95 and i dont think it should be any warmer

how high are your idle temps?

There was a video on ltt about aio vs air cooling which found that a 360 aio doesn't have to be the non plus ultra.
If you really want to stay at that frequency and voltage, you should either consider deliding, or building a custom loop.

If there’s a goal to having it run so high, just let it burn or get better cooling. Turned mine down at it can’t really do anything for me at 5.0 that it can’t do at 4.5.
