first time building pc, gtx970 heating up case

benniboi · Nov 29, 2015

I recently bought my computer on black friday.
basic specs are
asus z97-a
i7 4790k
gtx970

currently running the cpu on a stock fan, since i am not considering OC atm.

right now the problem is the pc is restarting when i am either running the stress test or playing dota 2 (only 2 things i tested).

video card was running at around 72 C
and the back of the video card is heating the RAM and CPU side of the motherboard up. I suspect this is the reason why the pc is restarting.

I am thinking to install some case fans on the front and top panel (which I do not have right now) to increase the air flow.

Am I doing the right thing?

UPDATE: Maybe I should open up both sides, have a fan blowing on the cpu side of the motherboard and try to run the stress test? See if that helps?

Have you thought about changing the fan speeds on your GPU?

TheSkyZX :

I was assuming that the original fan speed should be fine (starts at around 60C), since the video card company knows better than me. So I did not try to change the fan speed.

Which case do you have?

If you want to cool down your card, download MSI Afterburner and just increase the fan speed.

I have an MSI GTX 970 and the fans do not run till the card requires cooling which is a plus. If I play a game like Far Cry 4 at my custom settings that are high with settings added on I get 80% GPU usage while vysnced and about 70 Celsius.

My case has x2 front intake fans with a dust filter and x1 back exhaust fan. If I feel the heat coming out the back it is just warm not hot.

I live in cold England and it is winter but where do you live? Is it hot in your home?

I have never had the pc shut down from heat.

There must be something wrong with the heat dispersing pipes maybe, the card and the computer as a whole isn't getting rid of the heat properly.

Have you actually checked the temps of your CPu when gaming? Its highly unlikely this is due to the heat from the GTX 970.

Whats the full build specs?

madmatt30 · Nov 30, 2015

You want a 120mm front intake & a 120mm rear exhaust absolute bare minimum with any medium/high powered system like yours.

This is the tower case I bought from a sketchy chinese store

Graptik :

Would that work for Asus cards too?

Wayfall :

Today I am going to ncix definitely to get 5 case fans, 2 for front, 2 for top, and 1 for back.
and I live in Canada, but in my room I think its set to like 24 C >.>
I am thinking to get this:

I am at work atm, I ll reply to this later >.>
Is it still unlikely if I am using a stock fan (running low on budget)?
Would the PC restart if the RAM overheats?

madmatt30 · Nov 30, 2015

4 fans would be best mate IMO.
2 front intakes , 1 rear exhaust / 1top rear exhaust - leave the top front fan slot empty .

madmatt30 :

Are you trying to balance the air flow in the case?
does that mean I have to consider the power supply fan and GPU fan as well?

NightAntilli · Nov 30, 2015

MSI Afterburner works for pretty much all cards of all brands.

benniboi · Nov 30, 2015

NightAntilli :

Alright, thanks!

Yeah, even using the stock fan, it will limit performance because the 4790k will throttle using the stock fan, but the ram wont overheat and the CPU will just reduce performance, shouldnt crash.

That said, you should have a intake and exhaust fan in your case, its not good to run without any airflow.

List full specs when you can, as it could be another component like PSU.

This is the PSU I got:

Yeah thats ok, probably not that.

benniboi · Nov 30, 2015

RobCrezz :

Would it be possible that I got a defect video card then?

madmatt30 · Nov 30, 2015

Terrible PSU - 384w max on the 12v meaning its really a 430w unit at best & also has poor component quality.

It certainly doesn't deserve to be in a rig with an i7 & a 970 & under full stress its going to be perilously close to its limits.

I'm not saying 100% that's what's causing it (you do definitely need to sort some case cooling out) but I personally wouldn't use it.
