this is the reason I won't bother with SLI/Crossfire unless the gpu's would be straight blower design, there's no room for the cards to breath and that's alot of money to spend for it to overheat and shorten the lifespan of itself due to no room between them

I was having a heat issue with my new crossfire setup a while ago. IS there any space between the two cards?

I ended up rigging a mod setup where I took an extra 92mm fan and had it lying next to the two cards and my side panel 120mm fans blowing air in between them. It dropped the temp by 20 degrees. It may look shady but Ill take low 60 temps over high 80s 90s.


my chassis does allow fans on the side, i think the biggest being a 160mm or 140mm and also a vga bracket but it takes a 50x2x1 mm fan which i seem hard to find

What are some good fans out there that cool but are inexpensive?


I just used an old fan I had.

FYI this is how its set up inside the case, not my pic but the same setup basically

Air flow doesnt cut so what do you guys recommend?

I have two msi 560ti/OC's twin frozr

If those cards have teh "twin frozr" they should already be frozred and therefore not need to be cooled any further.


they seem to overheat none the less and the system shuts down


During a game sometimes it'll all of sudden go into black screen, the computer will still be running and just freeze causing me to do a force shutdown and reboot


How hot does it get and are you using 314.22 drivers?

get a better spaced motherboard.
Twin Frozers aren't great for SLI because they primarily vent out the sides. You could try blocking airflow and forcing it out the back, but that might hurt more than it helps.

The best way would be to put waterblocks on the cards and run a single custom water loop through them together (more than two cards needs another loop, and don't include the CPU in either loop).

My setup runs fine. I do have a 200mm fan on the side, which helps a little, but even without it, I wouldn't get crashing like yours. Only time that happens is if a push an even higher OC and run benchmarks.

Anyway, add a side intake and improve cable management/air flow if possible.
