Keeping PC cool

Hi,

a couple of days ago, I bought a GTX 970 from MSI. I am very happy with the card, but there is one thing that is worrying me. When I play especially more demanding games like Witcher 2, my PC gets really hot and loud. The case just feels like a radiator. I got a programm to measure temperature (HWINFO), and my CPU was at about 40-60°C max. and my GPU even reached around 80°C max.. I am using a "Xigmatek Asgard III" case. So far my PC is cooled by one CPU fan, one rear fan, the PSU fan and the two GPU fans. Now my questions are: Are these temps normal/safe? How can I cool my PC better? Would more fans make a big/significant difference? What fans do you recommend? Are side-panel fans useful? According to the internet, my case only supports an additional front fan and two side fans. Any tips/comments?

Thanks in advance!

Here are my specs in case it helps:

Intel Core I7 2600k
MSI GTX 970 Gaming 4G
1TB Hard Drive
8GB RAM
Asrock Z68 Extreme3 Gen3 Mainboard

You definitely need more air flow, a rear and PSU fan simply is not enough to cool a PC.

Take a look at this image for an idea of what you need.

Even the cheapest 5Euro fans will do a great difference! I personally suggest the Red wings by xilence. Cheap and quite quiet

Thanks for the quick replies! My PSU is top mounted and my case doesn`t offer top or bottom fans. I am also limited to one rear fan, two side fans and one front fan only. If i installed these, would the cooling be enough? Would merely a new front fan do the trick?

A quality front intake fan would be enough to make a difference indeed, I don't usually advise on side fans as a rule as I don't see them as helpful when creating clean air flow, but in your case, you could add them as exhausts and set your rear fan as an intake. You would need to experiment with different configurations to see the best results for your system.

EDIT: Should you want more air flow from the single front fan mount you can look at a 120 to 140mm fan adapter Bitfenix do them, thus allowing you to use larger spinners.

I think that by adding one front fan you'll significantly improve the airflow in your case. Cold air will be drawn in by the front fan, and is being blown directly at the GPU helping it run cooler. Some will also rise up to your CPU, feeding the CPU fan cooler air, and then finally all the warm air will be exhausted by your top fan and your PSU.

I would not use the side fan mounts at all.

In the future upgrading the case to something little less air restricted instead of the awkward fan layout you have now will give you better results and adding a fan will only improve on airflow

Ok, so i got the front fan working and the case definetely feels a lot cooler, but according to HWINFO my CPU is still at 60-70°C under load and the GPU reaches 70-80 C°. Is this safe? What else can i do without changing the case?

To try narrow down things. Just a few questions.

Which configuration of fans are you using? (Intake & Exhaust)
When was your CPU last Pasted?
Which programs/games are you using when you hit these temps?
Which case fans are you using?
What is the speed of your fans?
What is your current Ambient room temp?
Are your cables in order and tidy?
