Cooling a EVGA GTX 660 Superclocked

I've been having problems cooling my GTX 660 Superclocked. I am using a Skyline DIYPC-b case so I don't have very many options for fans. I tried looking into slot fans but my case doesn't support them. Should I Get a bunch of fans and try to find space for them, or should I buy a new case. If so, what case would you recommend? Here is my current rig:
Intel Core i5-3570
Asrock b75m r2.0
4gb DDR3 (Don't know the brand)
EVGA GTX 660 Superclocked
Seagate Barracuda 500gb 7200rpm HDD
LOGISYS 575w PSU
A Baaqi wireless card, not sure which one.

My CPU runs at about 38°c-45°c and my GPU runs at 37°c(when not doing anything)-56°c(When playing games like BF3). Also note that I used EVGA Precision X to kick the fan speed up to as high as it could go.(74%)
 
Those are actually pretty good temps. You shouldn't need to do anything. That's cooler than what my video card runs at and I have an big and fairly expensive case with 4 case fans (one of which is blowing air right on top of my video card).
 
From looking on Newegg you may only have an option for two 80MM fans, one rear, one on the side panel.

As for the temps, my 3570K runs around 30-33C @ stock clock, and my 7870 XT run around 33C @ stock clocks when at idle. I've seen 65-70C on the CPU and under 65C on the GPU while playing BF3 highest settings, @ 1680x1050, which is the highest supported resolution from my monitor. With my preset fan curves on the GPU, it runs @ 80% when running over 65C

This is in a Lancool PC-K62 Case with three 140MM intake fans, one 120MM exhaust fan, Hyper 212 EVO 120MM push/pull.

I don't think your facing a heat issue unless.
 
Yeah, but my computer keeps shutting off while playing games like Crysis 3 and BF3. It just kind of powers off and the starts up again after about 25-30 mins of gameplay. When I feel the side of my case after this happens, it is blazing hot and my temps for my 660 are at about 60c-70c when I check them at startup, but they cool back down in a couple of minutes. Not sure if this is a cooling issue or a PSU issue.

That probably would have been good information to put in your first post...

Regardless, try and monitor your temperatures using HW Monitor and see how high they actually get. I suspect a faulty PSU or GPU.
 
Yeah, so after about 20 mins of gameplay, my computer just powers off. I can only play when I have my psu set to 110v but if I have it a 230v, it says: bf3.exe has stopped working when I try to launch. I think it's a faulty PSU or GPU settings. I dunno exactly though.
 
80% of PC failures are PSU related. That's my guess, how old and what brand is it?

Your system may not be overheating but your PS maybe.

That sounds like bull to me. I agree that Power Supplies can cause problems frequently but 80 percent is way too high.

It's not a great brand but even then it should still power the 660. Try a different power supply if you can get your hands on one. This is probably a yes but I assume you plugged in the 6 pin connector for the video card at the end?
