My system is in my signature. I'd like to mount a 120mm fan on my case door. Reason being is that I feel that my NB47J passive chipset cooler is getting really hot and it might be the causes of my intermittent hard lock ups. I already have a Panaflo 120mm. The thing is, how big of a hole would I cut through the side so that it can suck and push air? I already mounted the fan so I have the mounting holes drilled through.
