Side panel fan placement?

post #1 of 3
Thread Starter 
I have 2 graphics cards, one is reference, one isn't. From what I gather reference models intake air, and non-reference exhaust it. I have 2 fans on my side panel pulling air out of my case but I'm worried that because of this, my reference GPU doesn't have enough air to pull in and is getting hotter than it needs too. What would be the best setting? Obviously I could set the top side panel fan to pull air into the case, and the bottom one to pull air out corresponding to the GPU nearest to them but I don't want to create some weird vortex as they are right next to each other. Any ideas? They are connected to the same channel on a fan controller and they are the same model so they are both running at exactly the same speed.

When I had my HAF 932, I always had the big fan on the side as an intake - are you sure it's not an intake?

Anyhow, it's best to have pretty much every fan in the case set to be an intake, with a single exhaust at the back. The air inside your case gets exhausted pretty quickly - better to have air taken in.

I have a reference GTX 570 and when I didn't have it water cooled, it exhausted air... weird. Must be a difference with the ATI air coolers or something.

Side panel fans remain as intake to give as much fresh air to both cards. The MSI will dump the heat inside the case. Put the MSI as primary card and the reference as secondary with bottom case fan as intake. This will give enough fresh air to bottom card and push the hot air from MSI upward to top side fan to dump heat outside. This will minimize hot from air circulating inside the case heating up other components unnecessarily.
