Hi, bought a BitFenix Prodigy M for my mATX build, have it all put together and everything's running smoothly, have a question regarding fan layout and temps.

Specs:
- Maximus VII Gene
- i7-4770k OCed to 4GHz
- H100i w/ 2xAF120 fans (exhaust)
- 16GB RAM (4x4GB)
- ASUS 780Ti DirectCUII OC
- 2xAF120 fans (intake)
- 1xNoctua 140mm (exhaust)

My fan layout is below, CPU is idling around mid-30s, GPU idling also around the same (both 30-37 range) - my question is... are the H100i fans set to exhaust fighting with the GPU fans (presumably intaking air to push onto the video card), and if so, is that an issue?

I was also considering bottom exhaust, intaking through the rear fan and rad fans... but that's counter intuitive to the whole heat rising thing.

Any help would be appreciated! Thanks.

All I can really say is to experiment and see what works best for you. Every setup is slightly different and there's no guarantee that what works for one setup will work for another.

I'm running an i7-4770K @ 4.2GHz and an R9-290. The R9 has a 3rd party cooler which pumps heat into the case and most of it is exhausted through the H80. This is effectively the opposite of what you're trying to avoid but it's what works best for me.

I have the same case with slightly different components but the same quandary. I have an H80 mounted on the rear as well as a DVD drive so only have a single top fan. After much testing I found that the top fans are better blowing the air downwards into the case. The rear exhaust fan I would leave as it is. I found the graphics card didn't overheat as much.

That seems to make sense also... as if I set the top to fans to intake, and the rest to exhaust, I avoid recycling (to a certain degree) the hot air being exhaust from the back and side, only issue is, with my radiator sitting right on top of the graphics card, if I set it to intake, it will effectively be pumping the CPU heat back into the case... and right on top of the GPU :(
