http://easypckits.com/ so i ordered a lapping kit which consists of 400-2000 grit sandpaper to lap my ihs fan. i would just like to let anyone who is interested in something like this that the aforementioned link is a great company i was thoroughly impressed with them the kit was only 5 dollars with shipping, which you may say well its only sandpaper, well go to your local hardware and hobby shops and ask for 2000 grit sandpaper. if you do manage to find it(which i did) you are forced to but a pack of each which can get expensive........and they also sent me a thank you gift which was a big bag of cable ties not much but cmon its free. so on to the lapping i will post any temp reduction here when i am done prolly in like 5 hours ugh.
