Hey i wanted to know if people with this case adjusted their fans in any way? Did you replace the top fans with 120 mm fans, Did you put the optional fans on that is to the left of the hard drive cage?

What are your temp.,?

I turned the top 230mm fans upside down to where the fans are sucking air in. Then I used some cardboard to direct the downward flow towards the top rear 120mm fan. I have a high speed 120mm fan in the top rear so my case is now a wind tunnel. It dropped 7c off my cpu temps and Im sure cools my chipset like crazy. I also installed the hard drive fans 2x120mm fans behind hard drive that pushes air towards my gpu. I also put pci slot box fan thing on and have a high speed 120mm fan there as well.

I kept the top 230's there since they move a decent amount of air without hardly any noise. I just can't see 3 120's moving more air without getting noisy. Also, I put 2 Scythe S-Flex "E" fans on the optional HDD Fan Rack. I think it definitely helps with moving more air across the PCI slots. The bottom optional 120 fan mount I decided to pass on, because if you put a fan there, it prevents you from removing the dust filter under the PS, but this might not be a big deal if you put your PS upside down, so the fan is on the top. I have mine on the bottom because I have a wood floor, and there's plenty of space for it to suck up the cool air from below the bottom of the case. If I was on carpet, I'd flip the PS, or put the case on stilts.

My room is fairly warm (75-80F) but that beast of a case only gets about 3-5F warmer than the outside.
