"Stand-off's" refer to the four receper bolt's which themselves thread into the black-plate of Thermalright SLK and SP-94 type heatsinks. These stand-offs which screw into that mounting X plate, accept the mounting screws which hold down the heatsink. You have to remove about 1mm from each, and the from the bottom of the screws which screw into them. This is to lower the total height of the heatsink to accomodate the altered height of any P4 with it's IHS removed. Here's pic's of the stand-off's and their corrosponding screws;

Here's a close-up of the 3.0C core, and my 2.4C with IHS removed gave me another 30Mhz, and about 5c overall temp drop. The 3.0C did even better with a 200MHz OC differential, and about 7C drop in temp. I imagine this is due to the convex, or concave imperfections in these IHS.

No matter how their applied (by machine) they still vary due to micro-imperfections in metal, and TIM thickness. If just a few more milligrams of TIM is placed between IHS and core, this could lift the IHS just a few tenths of a milimeter higher, or lower. Point being it's not a perfect manufacturing system by any means and the fact it's taking place in plants thousands of miles away doesn't help the consistancy factor. The fact some Malay's overclock better then some Costa Rica's indicates this. My newest project is to consider removing both the A64, and Prescott IHS's.

Man, it takes the eyes of a spider to clear up the fuzzy pictures. Is the ground moving or is it me? :grr:

That's why I published my pic's. I thought I'd assist "Spidy" in clearing things up. After all he's so often misunderstood.

On the right is my 3.0C IHS removed, on the left the 2.4C. I forgot to clean them up, they were in hybernation. So pardon the dust, huhuhuhemmm......

uke:

By the way Jort, although your pictures are blurry, you did an excllent job of removing the IHS's! Look's like you cleaned them up nice. No traces of epoxy like on mine. I had to leave extra on one though, so I could tell them apart...
