Hot GPU - So what?

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...

Probably best off asking in case central for further advice on what case to use which will provide you with excellent gpu cooling potential. :)
 
Using two heat dumper gigabyte 670's here. Not a great gap between them on this new motherboard.



In bf3 the top one hits 71c, bottom one at 55c. Been playing a bit of bf4 today and they max at 58 and 53c respectively. Probably down to lower fps in this game. At times in bf3 the frame rate is too high therefore higher temps. Got the fans set on a 1-1 ratio in ab.

Steady on chief, what sort of rig needs that much air flow, 2x R290x? :p

Might be overkill to some for sure. For me though with having two gpu's if i took away two fans then one gpu would be getting starved. I guess it depends on the case itself and how many fans you have. For me it goes like this.

Two heat zones on the gpu. 1 on the core and 1 on the vrm. So having two fans intaking or exhausting on both gpu's targets the two different areas producing heat. It may seem like overkill to some, but it ensures the best possible temps. What's more if you're OCD like me it gives you identical temps on both gpu's. Something that's not easy to replicate when using a multi gpu setup on air. :p

My gt610 has been folding pretty much 24/7 since april this year most of the time between. 90-100c, so it must take a while to kill a gpu with that kind of temperature when your just gaming for a few hours a day.

It's temperature cycles that kill electronics - Hot>Cold>Hot etc, rather than the out and out temperature (as long as it's within spec ofc)
