[SOLVED] CPU Hot while gaming

[rossmmm]

Hi my computer is getting hot as hell (90 degrees plus according to speccy) during games and causing the computer to reboot itself. I think the problem is the thermal paste and possibly dust in the computer, could their be potentially anything else causing this issue? the game is total war warhammer 2 and it runs fine even on ultra but will just reboot it self when ever a game is entered especially online.

gtx 970
600w psu
Intel I7 4700k (something like that)
3 fans
Computer is 4 years old
16GB RAM
Graphics/geoforce driver up to date
Tried resetting windows and reinstalling the game already

 

[rossmmm]

Think their is 4 fans actually

I would clean out your cpu fan of dust and make sure that all of the intake/exhaust fans are working correctly. See if temps improve from there, might also be worth re applying some thermal paste.

I suspect you're using the stock cooler for that cpu. Can you confirm?

 

[rossmmm]

The fan above the cpu is a intel one

 

[rossmmm]

So I assume that’s the stock cooler

Yes that will be the stock cooler. It isn't the best however it should be sufficient enough to cool it not so it overheats this badly. It will need cleaning because there will be dust built up on the radiator.

 

[rossmmm]

Yeah gonna try to hold of some thermal paste and compressed air to clean it out

If it's a stock cooler, then that is the problem. The stock cooler was designed for end users that don't run Prime 95 or load tests. If your cpu has to be a 100% load for video editing, rendering, content creation, then you'll have to purchase a better cpu cooler. No thermal paste or canned are will resolve your problem. I've been down this road before.

I am not sure that the cooling is the problem. I have had my 2600K running at 100 C when the cooler was failing and the machine never crashed. If fixing the cooling doesn't fix the problem look at the power supply as it may be starting to fail under load.

First of all, does your case supply sufficient intake airflow to allow a cooler to do it's job.
Two front 120mm intake fans or better.

What is your temperature at idle?
If any cooler is working and installed properly, I expect to see 10-15c. over ambient.
Are all 4 pushpins through the motherboard and locked?
Does the cooler wiggle if you nudge it?

Likely, you need to remount your cooler.
Buy some thermal paste and use alcohol to clean off the old paste.

----------------how to mount the stock Intel cooler--------------

The stock Intel cooler can be tricky to install.
A poor installation will result in higher cpu temperatures.
If properly mounted, you should expect temperatures at idle to be 10-15c. over ambient.

To mount the Intel stock cooler properly, place the motherboard on top of the foam or cardboard backing that was packed with the motherboard.
The stock cooler will come with paste pre applied, it looks like three grey strips.
The 4 push pins should come in the proper position for installation, that is with the pins rotated in the opposite direction of the arrow,(clockwise)
and pulled up as far as they can go.
Take the time to play with the pushpin mechanism until you know how they work.

Orient the 4 pins so that they are exactly over the motherboard holes.
If one is out of place, you will damage the pins which are delicate.
Push down on a DIAGONAL pair of pins at the same time. Then the other pair.

When you push down on the top black pins, it expands the white plastic pins to fix the cooler in place.

If you do them one at a time, you will not get the cooler on straight.
Lastly, look at the back of the motherboard to verify that all 4 pins are equally through the motherboard, and that the cooler is on firmly.
This last step must be done, which is why the motherboard should be out of the case to do the job. Or you need a case with a opening that lets you see the pins.
It is possible to mount the cooler with the motherboard mounted in the case, but you can then never be certain that the push pins are inserted properly
unless you can verify that the pins are through the motherboard and locked.

If you should need to remove the cooler, turn the pins counter clockwise to unlock them.
You will need to clean off the old paste and reapply new if you ever take the cooler off.
Clean off old paste with alcohol and a lint free paper like a coffee filter.

If you are overclocking your i7-4700K, you really need a better cooler than stock.
If you have 160mm available in your case, I recommend the scythe kotetsu for $35
