CPU at 85C at 100% Full load

[Haris Mahmood]

Hi

i have just set up my new build with new thermal paste and a coolermaster 212 evo cooler for the CPU.

The CPU is a I7-4790k

At idle my cpu is at 25-30C
at 100% full load it maxes to 80C

is this safe and ok for my CPU?

The maximum junction temperature on Ivy Bridge was 105C but Intel reduced that a bit for Haswell, don't remember if it was 98C ot 102C but if you are going to overclock, you obviously do not want to get anywhere near that.

80C is a generally safe core temperature but at the upper end of what most overclockers feel comfortable with.

Less than 70C core temperature under load is a safe area many OCers like to be in - very low likelihood of causing any damage to the chip.

The 80C you read is the max package (IHS) temperature.

I would not recommend 80 degrees. Reinstall the cooler put a pea of paste on the centre of the CPU and screw down the Hyper 212 EVO. I wouldnt recommend OC'ing at all with a hyper 212 evo but some do and find it great. Personally I have a NHU14S which is nearly triple the price but a beast cooler. I have my i5 4690k OC'd to 4.4ghz with temps of 60 on full load.

i havent overclocked my CPU , its all stock,
heres a screenshot of the readings http://gyazo.com/b99cfad8c39f82a53797b755722ca9da
so its ok and safe?

 

[jty0yt]

NO IT IS NOT SAFE! TAKE THAT OFF AND REAPPLY IT IMMEDIATELY

 

[TopLuca]

As long as it stays under 80 degrees its going to be safe

 

[jty0yt]

His is at 90 degrees, it isnt safe.

 

[TopLuca]

I've not seen the picture and you're right , 90s aren't safe.

i dont know what to do , i have re applied thermal paste and the heatsink is fully secure...

try HWmonitor , temps might not be 100% accurate on the program you're using.

I dont know whats wrong?

Your CPU v core is too high. Lower it in your BIOS to 1.2v and turn off adaptive voltage to offset mode if you have it turned on

ok , i lowered v core to 1.2v but i couldn't find adaptive voltage on the bios
my temperature is now 70-75c full load , a bit better.

is that good enough and safe for my CPU?

As said above your vcore is way too high, have a look here :- http://www.tomshardware.co.uk/answers/id-2195949/4790k-standard-vcore-vrin.html

BTW http://gyazo.com/b99cfad8c39f82a53797b755722ca9da shows a multiplier of 42 @ 100% load, if you've not OCed then should that not be a multiplier of 40? Have you installed MB software that automatically OC's?
