CPU temperature extremely high with no reason

Ras23 · Nov 6, 2016

Hello. My computer is having VERY high temperatures when a program is open, even without use of the processor. The Water Cooler is working right, thermal paste recently changed.
The northbridge and mosfet very hot. I can not touch them
I wonder if this has solution and if I should worry...
The Air That comes out of this cooler about 35 degrees, between cold and hot

Temperature when only battle.net is open (blizzard)

Temperature when nothing is open

All the programs show the same temperature (HWMonitor , Core Temp, Aida64...

My setup:
Mobo: Gigabyte 990XA-UD3 (rev 3.0)
CPU: AMD FX 9370 (4.5GHz) / CoolerMaster Seidon 120v
Font: Corsair CX 750w
GPU: GTX 970
Ram: 16gb
Windows 10 64Bits

Nevermind just saw that bit.

Is it just cut off or does it really say 0rpm on cpu cooler?

izoli :

just cut off

Something is not seated right or something kinky is going on. The reason is the game. It of course causes the CPU to work more. And the reason for more heat can only be due to the CPU cooler. Consider this guy http://www.tomshardware.com/answers/id-3084719/4690k-reasonable-temps.html . He was using a H100i which is a better cooler than that little Cooler Master. But his CPU temp. was going where yours is when under a heavy load. The difference here is your thermal paste? or compound or grease? has been recently changed. How were the temps. before the change? The same? The change did nothing? Cooler? How much thermal compound? About the size of a very small pea? I spread mine with my CPU's clamshell protective plastic case. I used about 2 long grain rice dabs. SOme just put a glob and squish it with the heatsink. The cooler MIGHT be defective or you might not have seated the cooler correctly. It's( the radiator) mounted to the top of your case and exhausting? Where's the heat going? Are you sure there aren't any lines that are kinked/bent?

You said the cooler is working right. What does that mean? The fan is spinning? How are you certain the coolant inside is circulating correctly?

When I said the battle.net was open I meant the own battle.net and not a game.
All this problem started after I change the cpu thermal paste. The cooler seems to be working normally and properly seated (I can hear the fluids passing through the pipes). The radiator is mounted at the side of the case and its normal. The cooler / pump is working, but since I bought it has a problem: In the first initialization of the day it does not turn on the pump and the processor heats up too much, so after I restart the computer sometimes he returns to work.
But what worries me is the mosfet and the north bridge, I can not touch them without burning my finger (believe me I tried ...)
I'm thinking that might be the mother board, but would like some orientation. Should I lead to a specialist?

If it happened after thermal paste change I'd focus on that.

Or possibly forgetting a step when putting the cooler back on like plugging something in or unevenly tightening screws.

What type did you use and how much?

Ras23 · Nov 6, 2016

izoli :

I do not remember the type but I put sufficient to cover the entire CPU. I took up pump and thermal was not dry and was covering the whole cpu

izoli · Nov 6, 2016

If the pump is working off and on i would replace it right away.

Theres always a reason for the heat. What's the voltage supposed to be and what does bios show it at? If voltages look good ide replace thermal compound on NB/SB heatsinks as well or possibly consider an rma.

izoli · Nov 6, 2016

You should use as little as possible of the compound and spread it thin so it makes a smooth surface, you just want it to fill the "holes" on the cpu so people usually use about the size of a grain of rice or a pea and spread it out smooth.

If it's too thick it won't transfer heat as efficiently.

After I replaced the thermal paste on CPU, NB and MOSFET, i saw no difference and the same problem occurred; I bought a new water cooler and tested it;
The problem with the varying temperature is over, but the problem with the temperature of the NB and the MOSFET continues (when i touch it), but in the programs the temp shows 35 ° ~ 47 ° celsius in idle, so I am not worrying; In the future I will change the Mobo anyway.
Thank you for your help.
