Bear with me, I'm about to upload the IHS pics (comcast has slow upload speeds <img alt="" class="inlineimg" src="/images/smilies/confused.gif" style="border:0px solid;" title="Confused"> )

Whole process took a gruesome three hours because I couldn't get the darn zinc off the center of the IHS. The sandpaper kit I ordered from the highly dependable site, pckits.com (I think) only provided small (but rather efficient) sandpaper with grits ranging from 400-2000. Temps used to be a pathetic 48 idle 65 (even hitting 75 with dual prime) load. Now it's at a respectable (but still rather concerning) 36 idle 55 load (62 dual prime for 20 hrs). My question is, I have this at 367 fsb (2.93 ghz) with standard voltage for the cpu (1.325v), and should I increase it to higher volts? I've heard Chozart and others from several threads stating that when they increased the voltage, temps randomly dropped. Shouldn't temps drop if you have lower voltage?

I can't comment on your voltage question... But i do have a question about your lapping. After your 2000 grit, are there still scratches around the IHS if you don't focus on the reflection? I lapped mine and i can still see scratches, but if i look into the IHS, then i can see a reflection still.

Did you get those temperature readouts from Intel Thermal Analysis Tool (TAT) and any other program that reads Core temperatures?<br>
If so, those are pretty good temps.<br>
Keep upping voltage, just try and stay below 65C for Core (though most say 85C, but that seems TOO HOT).<br>
And yeah, increasing voltage => increases heat output => higher temps.<br>
Those other experiences are just anomalies where increasing voltage leads to lower temps...

Yep. Same here. There are still very minor scratches on the IHS if you don't focus on reflection. Shouldn't be that much of a concern though, because the main idea to get it as flat as possible. Besides, IMHO, I think that AS5 fills in any holes left by the minor scratches and does it quite well.

Well I got those temps from TAT and Core Temp (reports same temps for both). But when I use speed fan and the Gigabyte Easytune5, the temperatures seem a bit too low (25-31 idle) (40-44 load) (47-52 max dual prime for 30 hrs). I still can't find a way to lower those darn temps! <img alt="" class="inlineimg" src="/images/smilies/mad.gif" style="border:0px solid;" title="Mad">

Replace the 80mm fans in your case with 50CFM or higher fans. 120's with 100 or higher.<br><br>
Should do at least 2C. <img alt="" class="inlineimg" src="/images/smilies/tongue.gif" style="border:0px solid;" title="Stick Out Tongue">

Thanks. But I think I had like 7 internal case fans (I cut it down to 5) and the ambient system temps were 31 without the AC on and 26 with the AC on. It's just that my load temps explode when I do dual prime.

Nice lapping <img alt="" class="inlineimg" src="/images/smilies/thumb.gif" style="border:0px solid;" title="Thumb"> Since your warrenty for your CPU is already gone, why don't you just take off the IHS on your CPU? That will lower the temps much more, but also alot more dangerous then lapping but its worth it from what iv heard.

Did Intel stop soldering the IHS to the die?

They are now? Well I guess no more IHS removals.. You know a guy that damaged his FX-62??<br><br>

I have no idea. I heard that the P4s were soldered, but I had a dead P4 chip that I got from my electronics teacher and I took the IHS off but it wasn't soldered.

36/55 is far more tolerable. IMHO, I would keep it below 59C at full stress-level over long periods of time (6+ hrs).<br><br>
Remember that AS5 or other TIC's take longer to cure with lapped surfaces. Your temps should drop even further within the next 10 days (not just because of the weather change...)<br><br>
I have a lapped E6400 / Noctua 120 with 1.36 on the core, now runs at 32/44 and up to 48 w/ Prime95 x2 @ 12 hours.<br><br>
Prior to my lapping my temps were similar to yours.<br><br>
As mentioned before, make sure that you have good air circulation. It isn't impossible to get it with 80's, but it will be much easier and quieter with some 120's. I recommend Silverstone FM121 (110 CFM @ 2400 - 39 dBa). At 1200 RPM's the fans perform very well.<br><br>
Good job on the lapping...were you nervous?

Thanks. Yeah, I might get the Silverstone fan (heard its pretty decent). I guess I'll have to wait for the AS5 to cure. And yes, I was nervous <img alt="" class="inlineimg" src="/images/smilies/confused.gif" style="border:0px solid;" title="Confused"> . But after the success, I discovered that with proper care and handling, there should be no risks! <img alt="" class="inlineimg" src="/images/smilies/thumb.gif" style="border:0px solid;" title="Thumb">

Some dude at xtremesystems.org forum accidently removed his IHS without knowing that his FX 62 was soldered. He posted various deadly pics of his cpu <img alt="" class="inlineimg" src="/images/smilies/frown.gif" style="border:0px solid;" title="Frown"> Kinda feel sorry for the guy. Heard he dropped a grand on that sucker 3 months ago. But he says its okay, since he's going conroe <img alt="" class="inlineimg" src="/images/smilies/thumb.gif" style="border:0px solid;" title="Thumb">

I also read that you can remove soldered IHSs by raising the temp to 90C+ (it melts at about that temperature).

Hmm, I think my conroe is too young yet to be removing the IHS but that lap job looked great. I ordered a kit from easypc also so I'll try that and hopefully have my CPU waterblock by then! Not sure if I'll attempt to lap the Apogee block, does anyone have any experience as to the "flatness" of those water blocks??

I should have thought you'd want to lap, your not meant to have a giant x in the middle of it.
