Well if your going to replace your fans. Here are my suggestions.
This first fan is a 80mm, with 84-CFM. This is the best 80mm fan on the market. I use this for my cpu fan.

This second fan is a 80mm also, and it works at 50-CFM

Now these are what you want. This first fan is a 120mm, with 108-CFM. Very good fan.

This is the best fan i know of. Its a 120mm fan, with 125-CFM. I suggest getting at least one. Putting this on your removable side panel would help better then anything else.
