I have the basic koolance PC2-P case with the video card waterblock. Now, the performance of this case has always been mediocre yet extremely quiet (I like being able to hear ). On a whim I decided to put a low noise 92mm fan in the side to allow for some cool ait ro get into the case. I also put an 80mm exhaust fan on the rear and modified the power supply hold to allow an emermax to also act as an exhaust. The additional noise is not even noticable. However, before the mods I was registering a whopping 38C interior temp and 40C cpu temp at idle. Now after the mod I am sitting at 29C case temp and 34C cpu all at idle. Nice improvement for little effort and very little increase in noise. Will post a load temp comparison later.
