jaz Posted September 22, 2007 Posted September 22, 2007 I sent away for a lapping kit and am using my old xp-90 with it's 92cm blue led adjustable TT fan. I'm swithing from socket 754 to am2 and i sent away for the special bracket that i need, but i would like to hear about some results and improvements (if any) anybody got from lapping this heatsink. I don't like the nickel plating they put on there. Why on earth would they cover up the nice copper better condutive copper base with nickel plating? Never could make any sense of that move. Any input would most humbly be recieved. ;-0 Thanks in advance Share this post Link to post Share on other sites More sharing options...

Uncle_Mojo Posted September 23, 2007 Posted September 23, 2007 As a matter of fact, I have lapped an XP-90. I did it after the base became slightly "bowed" creating a low spot near the center of the base. A long lapping session, starting with 600 grit, brought the surface back flat and useable again. In the process, all the nickel plating was removed. I don't have any meaningful temp information, as the uneven base yielded poor cooling. Given the retention design of this cooler, and the ammount of material I had to remove, I think that lapping your XP-90 couldn,t help but improve cooling.

oc newbie Posted September 23, 2007 Posted September 23, 2007 It definitely improved my xp-90 but I think it was concave to begin with. Been so long since I did it that I wouldn't be sure on the temp difference. Share this post Link to post Share on other sites More sharing options...
Angry_Games Posted September 23, 2007 Posted September 23, 2007 nickel doesn't tarnish or corrode so they put a thin layer of it over the copper so that it always looks good (and again, doesn't corrode...but anyone who has put one on more than a few heatsinks over time has seen the copper base underneath) I lapped one of my HR-05 chipset pipes and it came out mirror smooth but the XP-90 is a bit mother, lots of area so I'm waiting for my glass guy to show up with some 4"x8" 1/4" thick glasslets (heh, I just made that up) before I get started. If he can get enough of them, I might have him shave/shape them a bit and sell them here. He was telling me today he even had access to colored glass which might be pretty cool (but it's true flat glass stuff, not no chinzy thin piece that covers a picture in a frame lol) Share this post Link to post Share on other sites More sharing options...
tomb9712 Posted October 2, 2007 Posted October 2, 2007 I've lapped 3 XP90's, and it ain't easy. It takes some time to do but the benefits are pretty big. My first try I got about 4 degrees lower, but my second and third tries I got 6-8 degrees. Share this post Link to post Share on other sites More sharing options...
soundx98 Posted October 2, 2007 Posted October 2, 2007 XP-120 I lapped back in 2005 Those are CDs on the wall in the reflection and a fuse on the Heatsink Share this post Link to post Share on other sites More sharing options...
jaz Posted October 12, 2007 Posted October 12, 2007 That's a hell of nice lapp job Soundx98! I was impatient and got all my stuff in before the lapp kit came and the bottom of my xp-90 looked better than i thought, so i just put a dab in the middle of the cpu and pushed it straight down clipping it on in a criss-cross, then giving it a little wiggle to get any air trapped in there out, and she idles @ 31-33c with room temp around 75f, so i guess it's ok. Thanks for the input guys. Share this post Link to post Share on other sites More sharing options...
