8700K crazy temps on asus real bench or prime95.


Senior Member
HI. I have 8700K on stock with mobo Asus Z370 Pro Gaming + case Fractal Design R5. Cpu temps on games are fine 70C+.
3dmark physic test looped 70-80C. Unigine Heave 50-65C max on some spots.

When i run Asus Real Bench it skyrockets in stress test to 95C, and i am stopping test.
In Prime95 its worst with small ftt,but i guess its using AVX.
Any ideas why it causing this?
My cpu cooler is Cryorig M9i.Cpu is not overclocked.

XMP profile enabled in bios on memory 3000mhz. UEFI STOCK bios. Cpu clocks during test 4700mhz.

Is sense to play with this for syntetics only? Thanks

Looking at the spec sheet, all is good upto 101c where it starts to seriously throttle. Had a look at the cooler and intel recommend atleast a 240mm AIO for those chips okr a 280mm if overclocking.

Actuallly multi core enhancement is pre overclock that intel nor board manufacturers informed people about without decent cooling 4.7GHZ on 6 cores will cause some serious heat. Plus you should actually dial in your voltage to around 1.2 to 1.25 don’t leave it on auto cause it adds to much voltage for the stock clocks you are running.i put money on it that your cpu it running over 1.32 volts if not more under load which is just to much.
