I'm going for a complete silent build so that eliminates top mounting of radiators. Thus I can put the radiator in the back, in the front and in the bottom. First - I can't put the radiator as intake because I'm running 1 - and will run 2 Titan Xs heavily overclocked each pulling about 350W with modded BIOSes. Pulling 350W or 700W respectively of heat into the case is a suicide - or at least its much better to exhaust it (provided you get sufficient intake).
Now as per placement itself:
- As stated top is not possible due to noise (not even from the readiator but from pumps etc.)
- I'm not putting it in the back because I have Noctua NH-D15S so it would get hot air and will eventually have two of them (I have two 120AIO GPUs).
- Putting the radiators in front and letting that hot air from my Titan X in the case (around 350W of it
) into the case is a suicide as I mentioned
. I have tried creating a custom shroud that then exhausted the air through the bottom exhaust, but it was a lot of husstle and when I simply placed the radiator as an exhaust on the bottom and saw temps drop ~5C.
- So bottom exhaust it is
I have 2x 140mm (Phanteks F140SP) & 1x120mm (Gentle typhoon AP-14) as front intake (I took out all cages and fitted that 120 in their place on top - works great) which gives me enough air in. I have one 140 exhuast in the end and then the 120 exhaust through radiator (soon to be 2x120) in the bottom. In witcher 3 - max GPU 60C (mostly running ~57-58C) and max CPU 59C (in AIDA stress test it gets to 80, but thats not real usage for me) - plus thats with fans at around 80% (1000rpm).
