Now.. this may sound silly but do i have to install the fan so that it is sucking air into the CPU casing or out of the casing? :embrass:
Er, now you're getting me puzzled. You had mentioned it was a CPU fan so is it for a heatsink or not?
In a typical fully assembled tower case, you'd have the following fans:
1. Chassis fans
2. CPU Heatsink fan
3. Northbridge fan (sometimes the manufacturer just use a large heatsink)
4. Graphics card fan (sometimes there isn't one)
5. PSU fan(s)
Chassis fans blow both in and out depending on their locations - the ones in front/on top/ by the sides are meant to suck cool air in, the ones at the rear typically suck warm air out.
CPU Heatsink fans and the fans found on chipsets typically blow DOWNwards onto the heatsinks.
So which fan type is yours? Doesn't sound like a CPU heatsink fan now.
Typically on the mainboard, there will be at least one power header for one 12V chassis fan (usually two these days) and another for the CPU fan, both speed controllable by the motherboard itself via the bios or the fan utility that comes with the board. I had a brief look at your board on the Intel website and I would guess, just like my Intel board, you just set the fan to be controlled by your mainboard through the bios. But check your manual for details.
When you have too many chassis fans, the case can get very loud of course. What I do is run my two front intake chassis fans at 5V (they usually run at 12V but I made a line adapter to power them with 5). The one at the back runs at a variable speed which is determined by the mobo heat sensor. I am also using a massive Zalman heatsink with a very quiet fan that is also running at variable speeds controlled by the mobo thermostat. I gave up on all other chassis fans because things got too loud! (I have something like 10-15 chassis fans of different sizes lying around waiting to used for whatever crap project next time.)
