Prospector Posted March 31, 2005 Posted March 31, 2005 I just lapped my sink to 1500 grit,fired it back up and now I get System 30 Pwmic 29 CPU 29-31 Ambient 19 Hopefully when the AS5 cures it will drop a little more. The base on the XP-120 was Not flat. The base of the Tt Silent Tower I was using wasn't flat either. Share this post Link to post Share on other sites More sharing options...

Prospector Posted March 31, 2005 Posted March 31, 2005 Thanks.Now with all the case fans at idle it barely breaks 40 while Priming. It was certainly worth the time it took to do it. :nod: Share this post Link to post Share on other sites More sharing options...
Ubermann Posted March 31, 2005 Posted March 31, 2005 I lapped my xp-120 also. It was far from flat! Big curve in the middle, took ages to grind. CPU temp dont rise and fall like crazy if your remove the IHS also. Share this post Link to post Share on other sites More sharing options...

CPU temp dont rise and fall like crazy if your remove the IHS also. Ah now this is what I wanted to hear. So can you confirm that if your remove the IHS on an AMD64 you DO still have enough clamping pressure from the XP-120? I am very keen to take my IHS off (and of course, lap my XP-120).

psy^ Posted April 1, 2005 Posted April 1, 2005 So can you confirm that if your remove the IHS on an AMD64 you DO still have enough clamping pressure from the XP-120?. It will, but you need to modify the retention bracket Thermalright supply with the xp-120 first. See those little legs on the underside? You sand them about halfway down, maybe keep them taller than shorter to be safe. Share this post Link to post Share on other sites More sharing options...

Prospector Posted April 1, 2005 Posted April 1, 2005 Average 33-35 before lapping at idle so Iv'e cut 2degrees off and possibly 2-3 more when the AS5 cures.Right now Ambient temp is 20 System 31 PWMIC 30 CPU 31 All case fans at 50% rated speed :nod: Share this post Link to post Share on other sites More sharing options...
Headd Posted April 1, 2005 Posted April 1, 2005 Where can I get some instructions to lap? Is there a kit I could purchase? I'd certainly dedicate 4 hours for a few degrees less... Idle 37-38c atm, Prime 51c max Share this post Link to post Share on other sites More sharing options...
Vista Posted April 1, 2005 Posted April 1, 2005 This is one of the best guides I've seen that makes sense to me: http://www.overclockersclub.com/guides/hea...appingguide.php You might get somewhat better results with WD-40 or kerosene instead of soap or water as a cutting fluid/lubricant. Yes there are some kits available, but Home Depot and AutoZone can fix you up cheaper and faster. Share this post Link to post Share on other sites More sharing options...
Fracture Posted April 1, 2005 Posted April 1, 2005 WD-40 or Kerosene? For sandpaper? Wet sandpaper works just fine with water. Kerosene or WD-40 would just make more of a mess - it would offer no benefits that I can see. As a cutting fluid, yes, but not for lapping/sanding. 4 HOURS? Man, that's a long time. I've never spent more than 30 minutes to get a nice even finish. I go 600grit then 1500, and I usually arrive at a flat base quite quickly. If the finish is bad, I'll go 400/600/1500, but it still only takes me 30 minutes tops to get a nice finish. How come it took you 4 hours?
