First of all you'll need to cut a hole in the side of your case in line with your CPU. To keep things simple there no point going any larger than a 80mm as this will force the duct to be alot bigger than your cooler, unless you have a cooler with a 80mm+ fan?

You can buy a ducting mod by thermaltake but its expensive for wat you get and not very good. I would take a trip down to your local hardware store and look for some flexiable conduit.

Run the conduit from the fan mounted in the side of the computer to the fan mounted on your CPU cooler. Alot of people use the conduit used for extractor fans in bathrooms.

I don't think there's any need to cut a hole in the side of the case if you're going to be using flexible ducting. Just poit it through the hole in the back of the case. I've seen specialised ducting on US websites, but never found any here. So if any one knows of a local supplier, I'd be interested too.

not a good idea to duct the air inlet to the back of the case (unless the cpu fan sucks air through the heatsink). what happens is the cpu fan will suck in the hot air (which has just exited the pc) and your cpu temps will go real high. best bet is to place the duct up the front of the case.

the whole idea if side fans and/or ducting is to get cool air to the heatsink. don't forget case temp should only be a few degrees above room temp so the improvement in cpu temps will not be very big.

You'd also want to keep the ducting as short as possible and try to minimize turns. Any major turns would cause resistance to the air flow and be detrimental to the overall effectiveness of the ducting.

You also need to be aware that ducting may increase the noise of your system, afterall you'll be adding another fan. The duct itself will reduce the noise but wont totally kill it. The only real way to know what the noise level will be like is to try the mod.

Hi there, I cut a hole in the side of my case and put in a straight piece of 80mm pipe that stops a few mm off my cpu fan, this alows my PC to get a good supply of fresh air (as the fan sucks) my system has exhausts through the power supply (2 fans), because of big vid cards etc there is a lot of hot air inside my case, I also run a 120 mm fan to suck air into the case from the front, Any way by running fresh air directly to cpu I now fun approx 8 deg cooler on cpu, this cost me under $10.00 to do.

one thing to watch with front mounted fans is you can blow air out cpu ducting pipe if not done properly.
