Hmmph. The case is designed to fit a graphics card though so surely the manufactures thought about that while building it?! I will contact them and see what they say... redface.gif

I admit Im quite a newcomer to building PCs. However here are the load GPU temperature of a stock GTX760 in lets assume a case with perfect cooling:




I believe graphics cards can safely get up to about 120C so that gives about 40C leeway for my case with admittedly less than perfect cooling. I cant imagine gaming for more than about 1-2hrs at a time so hopefully that wouldnt let the heat build up too much? Does that seem logical?

I dont have parts yet but Ive ordered them all. The case is actually coming from Germany and should be here at the end of the week hopefully.

Thanks for your help.

Case is designed for HTPC use, not gaming.. and uses 1x 92mm fan to cool..
GTX 760 is designed for gaming, uses twice the power of a HTPC, and use 2x 92mm fans moving twice the amount of air the case fan does to cool it. This means it will be re-using it's own heated exhaust air.. which gets hotter every time it goes though the 760.

Just try it, see how it goes, but keep an eye on temps, if its too hot mod the case to have a 120/140 intake, shouldnt be too hard.

EDIT: Just looked more closely I think you could easily mod the case to have a 120mm on each of the cases sides therefore much improving airflow

EDIT:EDIT: Or even better have 2 120mm fans on the side with the GPU as intakes and the PSU should be enough for exhaust

Well ****! mad.gif I did get the case primarily for HTPC functions, but thought it might also be fun to play some games on the big screen occasionally too. I wasnt initially planning on getting such an expensive card but it was on sale and had the ACX silent cooler which I thought would be good to keep the noise down.

Doesnt the stock GTX 760 only have one 92mm fan? In which case it would be roughly balanced with the 92mm intake fan (excluding heat from other components). I assume graphics cards with two fans can run at lower speeds thus keeping the noise down. Surely it depends on the speed of the fans not just the size and quantity. Dont want to sound argumentative, just trying to get my head around it all!

As far as modifying the case goes I would be very reluctant to as its an expensive case and want to keep the aesthetics. I could potentially upgrade the fans to more powerful ones though. Might sound crazy, but if you think the case has decent enough exhaust through the PSU could I try reversing one of the 60mm exhaust fans to draw more air into the case?!

Thanks all!

Like we've said, build it and see.
The reason for the 2x fan 760 over 1x fan is for both more cooling and quieter cooling.
Using higher cfm case fans defeats the purpose of a quiet case.

Experiment and see what works best. It's possible that the PSU and open unused PCI slots can exhaust enough air to allow both rear 60mm fans to be intakes.. Might need to put a piece of cardboard between the 60mm fans and PCI slots to stop the heated air coming out slots from mixing with the 60mm intakes... Maybe 'L' shaped so heated exhaust doesn't go over top of divider and back in. 'L' could be a 90 degree fold between case and back of where it sets or cut to fit between shelf above to case and back to case. Hope that makes sense.
