Sanded down the IHS of a Q6600 to the silicone.

[silisli]

Hi, well Ive been sanding my qx6700 for 3 days now with 100grit and i dont think its any where close How hot can the thing get before it gets damaged? It gets pretty damn hot sanding it.

[Origin_Unknown]

that is amazing to be fair - 6 hours of sanding shows alot of patience, nevermind upper and lower arm strength.

also - that chip would make an uber keyring like that

[MidgetMariachi]

Sanding is always my least favorite part of any project. I don't have the patience. Imagine sanding an entire car for paint! Sucks...

Yes it will get hot...friction!!

I have a bleth sander in my metal shop class. I am going to take my dells pentium 4 540 to it on Monday. I will get back to you on how it goes I know theirs a lot of heat though so I hope it lives.

[c.freak]

Use a heatgun and the IHS goes off just around 35-45 sec (e6550).. Well.. sanding is ofcourse a method too, but ~6h Noway man!

[silisli]

is there any chance of killing it with the heat gun method?

Well guys just thought I would share my experience with this. Saw it and had to try it. I have a B3 X3220 that I figured if anything may help the temps why not.

Well got it all done and finally got it too boot back up again, Im using a V8 water block which is very flat. Found out that my temps are exactly the same as before with a lapped IHS. I was rather disapointed I must say. Tried several different moutnings and used both arctic silver and ICD and ICD actually was warmer by 1 or 2C.

Anyways gave me a fright becuase it woouldnt boot at first but figured out gotta be careful putting it in lol.

that sucks you didnt see any temperature improvements, though it may be your cooling that is not good enough (what kind of rad?)

js.

Its a bonnie heater core with a couple of shrouded silverstones.

I may end up doing another reseat later on and see what happens. Maybe I am using too much thermal paste. Was thinking that maybe I wont see any improvements until I get the super thinnest layer I can possibly get on it.

[xdrift0rx]

one quick question about applying thermal paste...when i do mine with AS-5 i make sure the whole IHS is covered, and when i do so i make sure its all the same color (of AS-5) am i using too much? or am i doing it correctly? i know it says to do a thin line down the middle for quad cores but i tried taht and didnt like the results.

[MADMAX22]

Use as little as possible and still maintain full contact is what your after. If you wanna smear a thin layer over the entire IHS then put the block on that works pretty good IMO. Just make sure everything is flat and that you have even pressure all the way around.

Past the 2 dies (or 1 on some of Wolfy pics etc) what are the 9 or so chips in by the dies? I'm asking because I'm going to try using a peltier + water setup and wondering what should be done in terms of condensation prevention within the ihs base.

If I were guessing I'd just be throwing in some dialectic grease and making sure nothing bothers the connections... but I dont want to guess

Thoughts?

those are resistors, if you plan on doing this dialectric grease will be necessary! imho, this mod is more trouble than it's worth; simply lapping the heat spreader until it's flat and smooth will yield results that are just as good. when i lapped mine i finished off with some 1500 grit automotive sandpaper and i think that made a big difference.

[Serpentarius]

crazy stunt .. but a good experience ..

maybe next time you should get a sanding drill bit .. that's cut down the time to 1/2 hr

[=ACID RAIN=]

Hehe..

I have 10C lower temps compared to the OP, but I haven't lapped anything. Even higher vcore (bios 1.55v, vdroop 1.45 normally, but 1.4v lowest stable) and same OC. Using an apogee CPU block, viperfang II for my 8800GT, and a bonneville heatcore (or similar, got it on ebay years ago) with a couple of slow moving san ace 120s.

You can get the IHS off people have done it but they allmost all have ended up cracking the cores. without the shim in there the cores get just a little bit too much pressurewhen mounting the heatsink they will crack. I believe there is a post in the beginning of this thread showing pictures of failed cores taking off the whole IHS. I would say with a water block you could get away with it if your careful but any kind of decent air cooling heatsink is going to have too much weight to it. I think if you did pop it off and glue you some shims juat a tiny bit higher then the cores back onto it. then lap till you even would be the fastest easyest way to do this mod.

It's more how carefully you put it on, I have a Xigmatek S1283 that I mounted on a Athlon XP with Zipties, etc that didn't destroy the core (And it let me get that Athlon XP to 2.3Ghz on a crappy mobo), if you put too much weight on one side, then it probably will crack, but if you put it VERY equally (i.e. 1 turn on each side at a time until fully tightened) then it should be fine unless you have like a TRUE copper on it or something.

If I can be bothered, I might try this on my PhII X3 720, it's running pretty cool now, but I might just try it for the heck, I'll wait to get water though as I have a hard enough time trusting the AM2+ mount for a TRUE with an IHS on it.

Ruslan, the pics is gone.. can you please upload the pics again?

sorry for waking an old thread again, but i must see this think i will attempt this on my Phenom II X4 940

[BigHops323]

Sweet, awesome to see that there is a reasonable chance for the chip to survive, not that I'd dare try it. Congrats.
