I just brought this absorbtion mat by akasa, I'm starting to wonder was this an good investment..does it eally work? I did not install it yet because I'm waiting for my case to come, I was reading the instructions and It say don'y cover up the vent holes but the case has those little holes on the side, should I cover em? or not. It has fan grillls 2 in the back and one in the front and I also have that fan blower thingie
