4, though I guess 5 if you count the tiny 40mm Arctic fan I stuck on my SSD to bring it below the 60-degree mark. 2x BeQuiet Silent Wings 3 on the front radiator (intake), a Noctua NF-A12x15 as an extra top intake to get some ambient-temp air around the motherboard, and a Nidec Gentle Typhoon (1850rpm) on the rear rad. All running at low RPMs, though the GT does run full speed when things heat up. Other than my case ambient being a bit toasty, this setup is enough to keep everything at very decent temps, including that power hog of a GPU. The CPU can exceed 60 degrees, don't think I've ever seen the GPU go above 52.
Also worth noting, all case fans are connected to the NZXT "smart hub" (oh dear how I hate that name), which is quite a good unit except for CAM crashing from time to time. Good thing my setup is capable of keeping temps in check even when fans are at their lowest setting
Thanks for hint, but the fan is installed properly. I don't have any issues with temperature. The only thing that bothers me is the noise of this 140 Akasa fan running on full speed. But i think it is the price of performance.
Everything with my airflow is fine. I have a slight overpressure but it helps a little bit with dust.
So your top fan has been flipped since the picture was taken? If not, it is indeed set up as an intake, which seems unnecessary - you'll still have positive pressure with three intake fans and two exhaust fans (as per your own illustration).
I have four fans in the case (PSU/CPU excluded). Two 120 intake and two exhaust (120+140). I think for cheaper cases it is better negative pressure than positive. This conclusion of mine based on Bit-tech extensive review that in general it is better to take the hot air faster from GPU and CPU area, than to pump fresh air in. Dust I can't fight anyway, I have come to terms with that. Just blow it with car compressor/air can from time to time and off we go. I'm never gonna invest into super expensive magnetic dust filters anyway and there are plenty of cracks, gaps and all sorts of mini holes in the chassis. Lost battle if you ask me. But I'd love to get my hands on some of Silverstone's vertical oriented cases, despite the fact convection in such small space doesn't really help all that much. Their success is more of combination of massive 180mm fans plus the fact there isn't much clutter between the fans the object they cool. Not my words, Puget's systems testing, I just happen to agree with their conclusions.
