hey is it a good idea to place an 80mm fan behind the mobo on the CM690? im thinking of trying it, since im gona have my phenom overclocked which means alot more heat.

Needs to be a 80x15mm fan.....

I have seen results somewhere that it actually increases heat....no idea how but if you have the right fan, maybe you can test it and see for us

I have a evercool 80x15mm fan behind the mobo which does fine. I haven't experienced more heat but I think that's because I have a E8400 cpu.

maybe the 80mm will works better as an exhaust? so that heat doesn't get trapped in between the mobo or in the case...

just a thought though

I'd automatically have it as an exhaust tbh

Do i have enough fans do you think?

um, what does having two fans layered on your TRUE accomplish? I mean, I can understand having one on both sides, but two on one side just seems redundant.

The one on the left is the fan - the one on the right [closes to the true] is a shroud - nothing in it

OH ok, that does make a bit more sense... but why?

directs the flow of air more and make the fan be "not as loud"
Think of it as fan pushing air pushing air through heatsink
Not just the fan puching it directly through it.


There was a really good analogy i read somewhere but i cannot remember it.....
