Need suggestions for improving airflow in H440

[Autoimmunity]

Hi there, I'm currently running my PC in an NZXT H440 case. While I really enjoy how silent this case is when using my PC on the desktop, I'm having some trouble when gaming.

 

I'm running the stock fans in front, with a Corsair AF140 Quiet edition in the rear and 2 Corsair SP120 high performance editions in the top with an h100i in push.

 

Thing is, I'm running 2x MSI Twin Frozr III HD 7950's in there too, and they are getting a bit toasty.  When running demanding games, I have seen the top card pushing 90c with the fans on full.  This also makes them very loud since they ramp up their fans to 4000 RPM and make on hell of a whine.

 

So, does anyone have any suggestions on how I could improve the airflow so that my GPU's don't melt?  Maybe replace some fans or change the layout?

Switch one of the stock fans in the front with the AF140 you have in the back

I have the same case and admittedly im not running two gpus but my gpu temps only get to 70c max with the fan running at 75%

Could invest in a x60 and a kraken g10 or go a custom loop to get around the heat issue, I think its more to do with restrictions of heat exhaust cause the case is restrictive in that right.

Not keen on water cooling? Try upgrading to better fans in the front and some for the roof as exhausts.

P.S dont amd cards run hot anyway? Two would be like an oven in there

Edit: noticed you are using the h100 so top fans are out

How close together do have the two cards? Try putting one pci slot between them. The top card might be overheating because its fans are pulling in hot air from the lower card

What fans would be good to upgrade the intake fans that would still be fairly quiet?  Also, yes, AMD cards run warm, but not THAT much warmer.  The cooler on the cards I have is quite a good one.

There is a 1 expansion slot gap between the two cards.  

 

 

I just want to know if it is safe to push 88c or so when playing heavy games.  I've heard that some of these AMD chips can run fine hot but I've never had experience with it as my old case was a damn vortex of air and kept them at 70c or below.

I've read that the h440 isnt the best at cooling, but a 20 degree difference just doesn't make sense to me. Take a look at the gpu cooler to see if everything is well with it

That's the question man, I'm looking for front fans too but I'm wanting a silent system that performs without making my ears bleed . Try noctua's or GT's in the front you need something that's going to move a lot of air. I know you can fit two 140 mm in there so that might be a possibility?

 

 

Do you really need to run two gpus? could sell them both and go for one amd I think its the 290x? or a gtx780 ect. Would be more stable and run somewhat cooler...

Use static pressure optimized fans as case fans, not airflow ones
