Why is my CPU so hot?

[George002000]

Hello TomsHardware,

Last weekend I changed my PC case from the NZXT Phantom to the NZXT H440. I've left all of the fans stock with the H440. Since upgrading cases my CPU seems to now be much much hotter than it use to be. While playing cs:go (Counter Strike:Global Offensive) for around 2 hours my CPU reaches highs of 80C while it use to never get higher then 70C.

What do you think the problem is? Thanks for the help, George.

What CPU? And how old is the thermal paste?

how certain you that the CPU heat sink is on correctly? it is quite easy to get one to not sit correctly (did it get bumped while moving it?). also can you explain the fan setup?

 

[mcnumpty23]

did you take off the heatsink while moving it from one case to the other?

It's the i7 4790k, thermal paste is about 2 months old.

I'm 100& certain that's it's been installed correctly as I didn't remove it when changing cases and I never went above 70C before.

I didn't, I left it on.

Did you?

is it the stock heatsink with those push pins? if so one or more may have become disengaged while moving it

^^ those push pins are lousy, that would not surprise me.

It isn't the stock, It's a Cooler master Hyper evo 212.

fair enough

just my opinion but i dont think there should be 10c difference between those cases

so my advice would be take off the heatsink and reseat it

even 70c seems a bit high if not overclocking it with a 212 evo

Thank you, when I say 70C I mean with my CPU being at 100% rendering a video and playing games.

ah only saw playing game in original post

still the same advice though--in my opinion the only thing that would cause a 10c difference between those cases is the heatsink may have loosened a little while swapping cases
or the case fans on the first case were going at a far faster speed etc
