My cpu was running at 98C and I thought I fixed it

[richyman]

...but I didnt. It runned hot so I reapplied thermal paste (which it was clearly missing) and after that didnt quite work I reinstalled the fan. That got my cpu running at 56C and I thought I had solved it. However I realized that whenever I play a game it rises up to a 100C. This led me to thinking this issue might not be on the hardware (maybe it is though). Why si my cpu running so hot? Thx in advanced.

I7 4790K

Maybe you messed up the chip.

Check the fan.

[chatter_box]

What CPU is it? Is it AMD or Intel, what model? and what CPU cooler are you using?

[stationvsbox]

Voltages?

stock, I7 4790K

 

It was running at 98C just now when I was playing civ 5, not really a demanding game. I stopped playing and it dropped to 60C.

wait does i7 4790k come with stock cooler?

Is that the cooler you're using?

did you overclock it?

[poker1059]

Possibly just a bad temperature sensor?  

Possible, no?

I wished but I noticed my fps dropping sometimes and thats when I meassured the temp, which matches the fps drops in timing.

right, try using a different program? Also if it's near 100c I'm sure it would've shut down to prevent further damage

I swear K chips don't come with stock coolers?

I did too, and it doesnt shut down, ive used it for a while now (I know maybe not the best call but I really like gaming) and it can run at 98C without shutting down,

 ez to verify

 

[stationvsbox]

How's the fan speed?

Then it has to be a bad sensor giving some bad readings on intel ARK the max tCASE Temp on the IHS is 74.04C and if it's hitting 90+ then the whole thing would just stop or something than just slow down a bit

You're incorrect.  Top teir consumer K chips shipping without coolers is only a very recent trend.  While my experience is limited, I assure you I have i5 2500K and i7 3770K stock intel coolers.

FANIN0: 2102 RPM

FANIN2: 868

FANIN4: 794 

I dont know which one is the cpu´s, could it be that the rpms decrease when I open games?

hmmm, but then why do my fps drop? sometimes my game freezes for around 2 seconds and at the end im at another spot in the game. And no,it isnt lag  .

Basically he reapplied thermal paste, having similar issues to you, (100C CPU temps with no good reason) Also try reseating your CPU and try taking out and putting back in your CMOS battery to eliminate more possibilities

Sensor giving false positives to throttle the CPU performance? Maybe?

The stock heatsink is pretty bad. After two years of use it couldnt keep my 4770 below 90C at load

Maybe,but I also noticed the load of the cpu apparently reached 100% (which I though was due to the temp). Anyway, tomorrow Ill tryresating my cpu as you said and see what happens.

I did rplace the thermal paste (of which it had almost none). 

 

I opened rainbow 6 siege, and even wihtout playing,just being in the menu, my temp rised to 90C. WTF. I closed it and it got down to 60C. 

Edit: Ill check if the rpms or the voltages change when I open games now.

You got way more issue's then playboy richyman.

I wouldnt be playing around like that until you find out whats wrong.

[richyman]

It seems to be the voltage! Iddle the voltage oscilated between 0.2V and 0.9V, however, as soon as I doble click the launcher the temp starts to rise and the voltage now oscilated between 0.8V and 1.2V. Now, how do I fix that? or is that even fixable?

That's completely normal. Voltage fluctuates on demand as the higher the CPU frequency goes the more voltage is required. 1.2V is nothing.

 

You're using a stock heatsink on a 4790k which is a chip well known for being way too hot for a simple stock heatsink over a long period of time. Go to a store and buy a Hyper 212 or similar for $20 and your problem should be fixed.
