Heatsink fan position
so recently i got a thermaltake sonic tower heatsink, and paired it with a silent 12cm LED fan.
my question is about the fan placement on the heatsink. the sonic tower gives the option of having the fan facing toward the back of the case, or towards the front of the case (where the hard drive, dvdrw are).
right now its facing towards the back (towards exhaust fan holes), but i was wondering how much of a performance decrease (or increase?) i would get by placing the fan facing toward the front. i want to be able to see the LED!
there are no other fans in the case, if that means anything.
