Hi, I usually like to think my idea of fan placement's alright. But this is a bit different from usual;
I've recently upgraded to water cooling and although at idle I get temps of around 28/29 degrees when there's a draught (regardless of temperature) if there's no air movement I can get idle temps of around 32/33. I know this may just be because there's no air movement over the thermistor, and that the temperatures may not be much lower, but I'm not actively cooling the motherboard chipset, and the hard drives and other components produce a pair amount of heat also.
Therefore I am considering some good aircooling to get flow through the case. Silence is pedigree and so I've decided on putting one (or two) 120mm fans (near silent thermaltake thunderblades, but should still shift easily enough air since it's for air movement rather than actual cooling) in the positions shown:
This isn't the norm I know, but due to the present of a window, and a rad housing above my case, and the ability to only have 1 80mm fan at the rear of the case, I don't have much choice.
It means I'll have the fan(s) on the other side of the drive bays, next to the motherboard, as shown (sort of) in the pic below:
I also have an 80mm fan shown here:
The top arrow shows the 80MM fan, while I may open up the PCI slots below to allow more air intake/outtake.
The question is, do you think this is a suitable idea, considering my options? And which way round would you put the fans? If I were to only use one 120mm fan, would you advise me using it as an exhaust so air is sucked in over the CPU (and GPU if I open up the PCI slots?) or have it blowing in, increasing pressure, and having the 80mm sucking air out of the case, over the processor? And would you opinions change if I were to use 120mm fans?
Thanks,
