Hot GPU - So what?

[wndsr]

I know we all like to think that cooler is better in terms of GPU and CPU temperatures, but what exactly is going to happen to my GPU if it reaches up to say 95 degrees under load?

Short term, long term, will it actually do anything provided it's cooled down again afterwards?

Thanks for the responses guys. I have two 770 cards together and one of them is getting significantly warmer than the other. I'm not sure if this is due to it working harder (although hardware monitor says they are both under the amount of load) or due to the fact it's getting less air due to the card so close beneath.

Either way on BF4 once it reaches its maximum temperature of about 83 degrees is throttles down causing a noticeable stutter for me in game. As I care more about getting a smooth experience, I've upped the maximum temperature to 93 - the highest allowed in MSI Afterburner.

Just want to make sure that I won't be picking exploded GPU out of my case in the next twelve months...

Sounds you you need a side exhaust fan or two to suck up the heat generating by your gpu's. I assume you have two identical cards dumping their heat inside the case?

Two exactly the same, aye. I have put on an old fan to try and suck some air out but it isn't ideal at all. I've only got a very small and cluttered case so for Christmas I was planning on getting one of those cool looking Corsair cube cases.

That looks really good - would you recommend it over the Corsair 540? I know it doesn't have side fans but was hoping to stick 5 of the Corsair High Performance fans on top and front.

When you say 'dumpers' - do all GPU's dump air or do different models do different things? Two of these.

Most of them dump heat in the case. This is not really a problem unless you have more than one gpu. When you have two dumping heat and no easy way to exhaust it then you get the problems you mention.

You can get models which dump 95% of the heat out the rear. These are ideal for multi gpu solutions, but they often come with other drawbacks such as increased noise over dual fan solutions and worse gpu cooling performance.

Blowers don't require side fans usually, but it can still help. Cards that dump heat in the case often benefit from side exhaust fans greatly.


Blower type fans below. Have one fan and an enclosed shroud to ensure most of the heat stays within the card shroud and is exhausted out the rear through the vents.

This makes a lot more sense now, cheers. Admittedly I am now debating whether or not the Corsair Carbide 540 is the right case for me to treat myself to...
