So I've been reading up on CPU and HS lapping and I decided to give it a go. I used 2 guides to assist me along the way:
http://www.overclockersclub.com/guides/lapping/ as a heatsink guide and http://forums.legitreviews.com/about10788.html as a CPU guide.
I went out and bought some 400, 800, 1000, and 2000 grit sandpaper which was surprisingly hard to find. I thought for sure Wal-Mart, Menards, or Home Depot would have them, but after I struck out at those places I wandered into a Murray's Auto Parts and got what I needed.
So, onto the good stuff. As you can see the Q6600 is overclocked to 3.4ghz, It usually runs at 3.6ghz but after seeing these temps I wanna step it down till the Arctic Silver 5 settles. I took some screens of my computers temps from Coretemp as a reference. Prime95 is used to set load.
Idle Before: 57, 58, 54, 54
Load Before: 81, 81, 75, 77
So needless to say I was getting a little worried. After a few hours of carefully lapping up to 2000 grit I have a shiny Q6600 and a very shiny Arctic Freezer 7 pro. As it turns out, the Q6600 was pretty Convex (budging in the middle), and the Freezer 7 was somewhat concave (bubbled inward) in the middle. Sorry I dont have a digital camera to document the work. I reapplied some Arctic Silver 5 and ran Coretemp to see the immediate results:
Idle right after: 59, 59, 54, 55
Load right after: 72, 71, 66, 67
As you can see my idle temps stayed that same if not increased 1 degree. More importantly, my load temps dropped 10 degrees immediately! Now the Arctic Silver 5 is still fresh and needs to be burned in to get maximum gains, so I will be updating this thread at the 3 day, 1 week, and 2 week mark with a graph to show my results.
If anyone was wondering if lapping is worth it, all I have to say is apparently yes!
