Cpu Temps massive jump help

Cpu 100 degrees at 100 percent load at 4.5ghz speed but if CPU speed at 4.4ghz it is max 75 degree's why is there such a massive temp difference?

It could be time to redo the the thermal paste.

It would help if you posted the make/model of your case and your CPU cooler.

but .1ghz seems crazy 20 degree celius plus increase for such a small increase in cpu speed asus multicore enhancement in bios is active

It's like anything else... when you get near the "top end", things start happening... fast.

Sort of like an engine in a race car. They're fine until you go past a certain rpm... then things get weird.
The 7700K has a base frequency of 4.2 Ghz... it's max. turbo frequency is 4.5 Ghz.

The CM EVO 212 is OK for lower TDP CPUs. But the 7700K is a 91w TDP processor.
I also use a CM Hyper 212 EVO but I have TWO fans on it... push/pull, and that's just on a 65W TDP CPU.

I also have 7 case fans.







Here's my idle temps...





When I run the CPU at 100%... it goes up to approx. 72-75C and stays there, because of all the cooling.


Also... I keep my room temp at approx. 64F, which helps as well.
