You also have to remember that depending where you are getting your readings from, they probably are wrong.
My "temp monitor" shows my chipset a 70C. Now I agree it is warm (since it is passively cooled), but it is no where near 70C. I have a 92mm fan blowing right accross it from the front and a 120mm fan in back for exhaust.
I have had zero lockups or problems.
What brand of fans do you have in there now? Are they the stock ones?
Here is a review of your case.
Review
I have the original Gaming Bomb. Mine comes with a 92mm fan in front standard, and a slot for the 120mm in back.
I went with these fans:
120mm
92mm
I went with fans that moved a little less air (120mm moves 60 CFM @ 24 dBA ) and the 92mm moves up to 48 CFM @ dBA because I wanted to not hear the fans that much.
With you able to get two 120mm fans and one 92mm fan, and if you can tolerate a little more noise, you could get something like
these.
They give you almost 80 CFM @ 30 dBA.
