Played around with my case fans tonight while thinking of what else I can do to change this case again. I ended up trying a few different setup ideas, and settled on (for the night ) reversing the top 80mm fan so that it is now intake instead of exhaust. Current fan setup... 80mm top fan IN 80mm side fan IN 120mm front fan IN 120mm rear fan OUT I'm still 95% sure that I'll be swapping that top fan out for a 120mm fan in the extremely near future (aka maybe tomorrow). I'm not sure yet though on whether or not I'll end up taking that top 80mm top fan out and replacing it with two 120mm fans both blowing IN. In order to do that I'd need to relocate the Blu-ray drive down a bay or two, but that's not really a big deal to me anyway. I already took out the dvd burner since it stopped reading discs sadly. When I put in another dvd burner it can always be mounted in the slot above/below the Blu-ray drive so that's not an issue. I have less than 0 need for three optical drives so I won't be losing anything there at all. If I do the top fans the way I'm thinking, then I'll need to change out the rear fan to something more powerful, without using the unholy 110cfm Slipstream which I don't have a speed controller for...meaning it will make my ears bleed. The way the fans are setup right now, the system is SOOOOOO quiet in comparison to how it was before (with the 80mm top fan blowing OUT) which already wasn't that bad at all. Temps are sweeter as well, I loaded up 3.8Ghz @ 1.392v and did a few 100% load tests with wPrime 1024M to see how it worked out. With the 80mm top IN and no 80mm side fan the cpu temps idled 24-25C varying, and load was 41C steady with a fairly slow rise from idle to max temp. With the 80mm top IN and 80mm side IN the cpu temps idled at 25C super solid, and load temp was 40C absolutely hardcore solid as a rock steady with an almost sleep worthy slow rise from idle to max temp. Both temps are better than when the 80mm top fan OUT was setup by a few degrees, and definitely by the rate at which temp would climb from idle to max. Before it wasn't a super spike in temps though it would get there fairly quickly, now especially with both 80's blowing in you could almost fall asleep waiting for the temps to hit max lol. Case temps are roughly 1-2 degrees cooler than before as well. Overall a good day Kei <--- curious to see if the 120(s) will make a significant difference Edit: forgot to mention that I may try one of those 80's or 120's on the bottom floor of the case as IN.
