Rad Fan Placement
 

here's my ghetto diagram

#1air~> |(rad) <~air
#2air~> |(rad) air~>
#3<~air |(rad) <~air

right now I have it on setup #3 and i"m getting about 46C idle. That's pretty high! Consider that the fan mounted on the rad is 120MM and the fan behind the rad is only an 80mm <due to the nature of my case that's wat I can fit behind the rad. Should I change the air flow setup.. If so, how? Which one is best. Thanks!

take out the 80mm and just run the 120mm sucking air through the rad and see if your temps drop.

Need more info, It might not be your radiators fault....or it could be a piece'o'crap.
