Hi guys,

Managed to find a buyer for my C2D rig so am doing a new i7 920 (air cool with Megahalem), so far I have plan to have the fans placed in this way...
one 120mmx38mm fan on the CPU Megahalem (blowing towards the rear)
one 120mmx38mm fan on the rear exhaust
one 120mmx38mm fan on the top-rear exhaust
one 120mmx25mm fan on the top-front exhaust (using the default rear fan that comes with the case)
one 200mmx30mm fan on the front intake (default)
one 200mmx30mm fan on the side intake (using the default top fan comes with the case)
Will wire the 38mm fans to a fan controller and will place dust filter on all intake fans.

My question for the above is will the 120mmx38mm on the two rear fans (top and rear) have enough clearance from the mobo and the megahalem? Also, any other advice/recommendation on the above setup?

Also, I would like to have advice on the below:
(1) Will it help to cool the system by placing fan behind the HDD cage (i.e. sucking air out of the HDD coming in from the front 200mm fan towards the MB/GC)? - note: I won't be able to remove the HDD tray since I need them for at least 4 drives.

(2) Is there any benefit in cooling to place a fan at the front in the 5.25" drive bay (using zip tie) and if it does, will it benefit more to have another at the back of the blowing air towards the RAM/CPU?

(3) I have no plan to put a fan at the bottom at this moment, is this advisable to have.

Thanks to all in advance...

I can speak from personal experience with a HAF922 and the amount of space I have between my True120Ultra and the 2 scythe slip stream 110cfm's I have on my rig. Granted they are
120mmx25mm versions but the clips that hold the fans to the heatsink are what comes the closest to the 200mm top exhaust fan. I'd say the maximum clearance on mine is about 3/8ths of an inch.

Thanks Mvgratz. Will get one 38mm first and check it out before plunging in for more.
