My PC keeps overheating!

Chris2964 · 13 Apr 2017 at 12:54

Last year I bought a PC Gaming System from - Skylake z170 Pro Gaming PC Configurator.
Parts -
Case :- NZXT H440
Power Supply :- XFX XTR Series 850W
OS :- Windows 10
Motherboard :- ASUS Z170-A
CPU :- Intel Core i5-6600K 3.9GHz (Skylake)
CPU cooler :- Alpenfohn Brocken ECO cooler CPU Cooler - 120mm
Memory :- Avexir Core White 8GB
Hard Drive :- WD Blue 1TB 7200rpm
Video Card :- MSI GTX970
Monitor :- ACER KA24HQ 24"
Mousepad :- SteelSeries QcK
Mouse :- MARS GAMING
Keyboard :- Logitec G19
Headset :- HyperX Cloud

I got Overclockers to build it for me and install the correct programs.

It may should stupid but when I play CSGO after about 1 hour of playing my computer totally freezes and I hear a buzzing sound. If I put my hand to the back of the PC where the fan is, it is pumping out really hot air. Playing other games such as GTA 5 I never have a problem.
I just want to know what the best thing to do in order to resolve this problem, do i need to install a program or take it back to the shop.
Many thanks
Chris Owen

If it's within warranty - contact overclockers via their Customer Services Forum - link.

If it's out of warranty you need to identify the cause of the freezing.

I would check your temps first - use MSI Afterburner plus real temp (although afterburner will do the CPU too) and monitor the temps of the GPU (especially) and CPU when playing CSGO. Or run dedicated stress apps Kombuster (again from MSI) to check the
GPU temps and prime 95 or similar to check CPU temps.

It wouldn't hurt to run memtest for a few hours if you're planning on going out too...

Report back with results.

I would open the case and check for dust build up - do you have cats/dogs?

check the filters

Chris2964 · 13 Apr 2017 at 13:40

Whewn i take the front panel off I have a vent that I can remove and that I sometimes hover to remove the dust but it still sometimes overheats even when I have removed the dust the day before and no I just have an outdoor rabit

Chris2964 · 13 Apr 2017 at 13:40

It is still in warranty so do I just need to ring them up and explain my PC's symptoms?

Plec · 13 Apr 2017 at 14:25

You could - but the customer services forum is sometimes easier. You can list the problems you're having and they will advise you accordingly. They'll ring you if necessary or vice versa if you feel your not explaining it properly.

But being in warranty is a big bonus - follow their lead to safe guard your warranty.

Alright thanks so much!

NP - good luck. Hopefully it's a simple fix - it could be a thermal problem which can have straight forward solutions.

Chris2964 · 13 Apr 2017 at 17:09

Could it be down to be not having enough exhaust fans in my PC, I have 3 intake ones at the front and only one at the back

Plec · 13 Apr 2017 at 17:13

That's plenty of fans - it could be dust accumulation, faulty fan, CPU not making decent contact with HS, corrupt memory on GPU, dodgy normal memory...

If you haven't confirmed it's overheating with monitoring software it could be anything - but on the face of your initial description it looks to be a thermal based problem. Not enough evidence to be conclusive yet...

Chris2964 · 13 Apr 2017 at 17:21

I have installed MSI afterburner and set automatic control fan speeds so when it reaches a specific temperature the fans will rotate at a higher RMP. Hopefully this will solve the issue?

Plec · 13 Apr 2017 at 17:29

If it's a thermal issue yes - did you check what temperature the card was reaching before you made the changes?

If not I would revert to your original profile and make a note of it's normal running temps for comparison. Note, you need to check your CPU temps at the same time.

Plus, if it has started to run hot there will be an underlining reason for this and sometimes throwing more RPM at the issue isn't the solution - there may be an issue with the card - the HS may have come loose from the GPU - or it's had poor contact from the start and you've not been aware.

Or it may not be the GPU at all - you need to check the temps (CPU and GPU) with the same configuration you were experiencing the problems to try and identify the weak link and then work form there. Otherwise you may end up masking the original problem and perhaps an even bigger issue...

Is the fan profile set to spin down the fans?

olivier renault · 14 Apr 2017 at 09:33

if it's heating up too easily, it's probably a unseated CPU cooler, or CPU fan not running. No way it should overheat with a 3rd party cooler. Not even with bad airflow.

User afterburner for GPU (and / or CCCP for CPU), and do Unigine / prime95 runs to stress test.
