I have a COSMOS 1000 case from Cooler Master. It was hand-built for my birthday January 24th. This morning I started up my computer and the front bottom fan was making a loud noise. I took the fan out and I am going to order a new one this afternoon. Will I be Okay running without that fan for a couple days on low graphics for games like Starcraft 2 and CoDmw2? The Box sits under a desk not in any open space. Should i bring the computer out from under the desk somewhat to let more air get into the box easier?
