As everyone knows a higher temprature difference between the cooling medium and the item being cooled results in better cooling as the air outside my PC case is cooler than the air inside it is of course logical to cool the cpu with this air and so ducting :D.
Step 1. Choose your ducting, my choices were Caraboat engine air intake pipe or 505 heater pipe. I Choose the caraboat engine air intake pipe even tho it smells of old boat.

Step 2. Cutting and shaping the ducting to fit the case.

Step 3. Attach it to your cpu fan, my cpu fan was ideally suited to ducting.

Step 4. Fit the cpu fan and ducting into your case.

Step 5. Solder and replace the resistors on the Multicolour fan guard that got broken when fitting the ducting.
