To add a front fan, you'll need to remove the front panel of the case. If you remove the sides, and look, you'll see some tabs that hold the front panel in place.............it's a pain in the butt, but you can remove it. Behind the front panel, you'll see the mounting spot for an 80mm fan. Make sure it's blowing IN when you install it.

If you decide to mount a side fan afterwards, you need to remove the wind tunnel. Just unscrew the screws holding that piece on, an 80mm fan will fit into that spot instead. I would not do that, for now, though..........just add the 80mm fan to the front. Your case has enough airflow to not need that side fan.

Latest report:

After adding a 80mm fan on the side at 2800RPM, the temp is downed significantly to.... 40~41C Idle from 50C and load temp now is ~53F.

It turned out I can not replace 2 fans inside the PS unit. It lloks like I have to stay at 225Mhz with Idle temp ~40C. Not too bad

well....hmmm Is it my uinderstanding that you have the rear case fan blowing air IN to your case? Typically i would suggest reversing this.

Optimally....youd like air intake to come from the bottom front of the case.....and the side panel. And the exhaust should be from the top rear, and the very top (blowhole fan).

As we know, heat rises, and the cooler the air inside the case, the better.

Also, i have a 3.0 C chip...or Northwood. You have the E or Prescott. Your chip runs notoriously hotter than mine does, so its difficult to compare your temps to mine. Looking good so far though....let see if we cant bump that up a bit more though....;D

I made an error in my last statement and you corrected me

. The 120mm fan in the back actually takes the air out. I tried to reverse it and the temp is increasing about 2C. I think I have to be happy with the improvement I had with the side fan. I can not think of anything I have not tried now

I would suggest moving the fan on the side (that you just installed) to the front. You need to move the "hot pocket" of air away from the hard drive. With that wind tunnel over the CPU, you don't really need a side fan, but you can certainly add one if you like. For now, try the fan in the front (installed behind the front panel) and reinstall the wind tunnel your case came with. Adjust it at close to the CPU fan as possible, and you won't really need a side fan.

And yes, more fans mean more noise........if ya wanna run with the big dogs, yer gonna make alot of noise.

You might also want to look into replacing the stock Cooler Master 120mm rear fan......they're usually pretty good, but go for as high a CFM as you can get. The 120mm fan will be quieter even at higher CFM's, as it doesn't have to spin as fast to move as much air.

Ideally, if you're going air-cooled, you'd want negative air pressure inside the case...........meaning, more CFM's going out than coming in. You'll also want a direct crossflow.......meaning one fan in the front, one in the rear. Like Toggle mentioned, a blowhole fan on the top of the case is nice, but you can get away without it, as long as you have good front- to- back ventilation.

To install a front fan in your case:

You have to remove the entire front panel. Take the sides off the case, and look toward the front of the case, at the backside of the front panel (next to the drive bays). You'll see six plastic tabs. Compress those a little bit, and pull the front off the case. Then, remove the front fan cover (four screws), and install the fan. Then snap the front panel back into place.

It turns out the case already has a fan in the front panel
