I recently built my 1st PC, and just wanted to get some opinions on whether or not my fan setup is OK. My temps aren't terrible for the most part, esp. considering my room is very warm, I'm OC'ing my cpu/gpu and I don't have the greatest heatsink (CM Hyper TX3) in the world. My case is a NZXT M59 with 3 case fans. 120mm side intake fan, 120mm rear exhaust and 120mm top exhaust. (The top fan is mounted on the fan slot that is closer to the front of the case) I have 2 90mm fans on the TX3 for Push/Pull and the exhaust fan on the TX3 pretty much points right at the rear exhaust case fan, which I would think helps get rid of the warm air the heatsink produces. My Core temps idle in the low to mid 40's and are mid 50's when gaming (mid to hi 50's with prime95). My GPU temps idle in the low 50s and peak at hi 60's to low 70's. I'm not too concerned about the temps, as I stated before, but am always interested in lowering them if possible.
Specs: CPU- Phenom x4 955 OC'd to 3.6, MOBO-ASUS M4A89GTD PRO/USB3, GPU's- 2x HD 4850 (Crossfire) OC'd to 690/1053, Win7 64b, Case- NZXT M59, RAM- 4gb OCZ Platinum 7-7-7-20 1333.
your fan set up is fine, i have the 212+ (similar to the TX3) and found using dual fans actually increased temps. i was not shocked since i tried a similar set up on a older HSF and found the same issue. the two fans both pointing out (one on the HSF and the case outake) actually slow each other down by not having a clear air path out. i found this issue both in my antec and my rosewill case.
i have two 120mm up front asintake. one 120mm in the back as outake. one 140mm outake over my HSF. one 120mm on my 212+ pointed towards the drives.
i don't have any side fans since i find they don't affect my temps unless run at high RPM and frankly my temps are fine and i don't care for the extra noise.
Thanks for the reply. I attached the 2nd fan to the TX3 shortly after I built the PC, so I dont really have anything to compare it to. How much of a difference did you notice in temps with 2 fans vs 1? I'm just trying to figure out if it's worth going through the process of comparing the 2 setups. If it's only a few degrees, then I'll leave it as-is. But if you think it could make a substantial difference (>5 degrees) then maybe I'll look into it. Thanks again for your opinion.
