IHS off of my proc

[covert24]

Hey, i have THIS CPU and THIS COOLER. Would i be able to take the IHS off of this proc and be ok to mount that cooler on it? since i know AMD has soldered some of there IHS' on i wanted to know if this one is soldered or not.

No idea whether you have a decent chance of doing this safely with an AMD proc. But at least with the Intels, it's likely you'll kill it.

lmao why would they even try to run the computer when half of the core was still on the IHS?! lmao. but i have done this procedure with a A64 3000+ winchester core with success and the temps were great. im just wondering about these new brisbane x2 4000+'s if they have a soldered on chip. the only A64 with a soldered on chip that i know of is the black edition series and some 6000+'s. i could be wrong tho.

Should only be the black series.

Pretty easy to tell if it is soldered, when you try to pull it it won't budge.

Insert CMA statement:

I believe there is no way you could put enough force to pull off soldered cores by trying to get the IHS off. I know you could not with the 6000+ unless you were using powertools and not the old razorblade method.

For what its worth, I was able to (easily) take off the IHS of my s939 X2 4400+. Take a razor to the black epoxy/glue/sealant. Be sure to find a A64 X2 IHS removal guide though (helps to see where the capacitors are under that IHS).

what is this RAZOR BLADE TEST that i keep reading everywhere to see if my processor is flat? how is it done?

Messures the flatness of your IHS.

The sharp side of the razor, also the side the cuts is placed flat in a 90 degree angle on the IHS.

You then look sideways, so the IHS is directly in front of you.

Any light passes though the razor blade and ihs = unflat ihs.

Its usually the second easiest method to determin how unflat your ihs is b4 you lap it, or think you need to lap it.

The first would be a stright grid reflection test, but its impossible to do without lapping your ihs to an almost mirror shine.


Razor method of hacking the IHS is different. You need 4 razors where you apply tension on each corner. You then get a mini torche and gently heat the ihs so the sodder melts. The tension and pressure from the 4 blades slowly peel the sodder and ihs off the Die.



So louis take your pick on which you wanted to know.


Also i heard most AM2 proc's are soddered. I hear E4300 and E4400 arent soddered. I was awefully tempted to buy one to see if i could hack the ihs off and recycle my storm waterblock for massive oc's. But i got lazy somewhere..


OH incase anyone is wondering.. there is no greater block still compared to a swiftech storm for direct IHS cooling.

Also i dont recomend you people hacking off the IHS. Reason is because the DIE is kinda fragle on the corners. You mount a heavy sink and apply the wrong tension on it. CRACK goes you die, and bye bye processor. Most IHS removals are done for waterblocks.


Also IHS vs Lapping differences shown to be no more then 4-5C tops. So sometimes its just not worth the risk.

thanks aigo. so i guess i will just head over to home depot (again) and get some sand paper in different grits to get me a mirror shine what grit stage do you think i should start and stop at? like what should the sequence be?

 

[LOUISSSSS]

yea i only got 1 sheet of 1000 grit paper. store didn't have any 800 and im' not a perfectionist so i didn't bother getting a 1200 for 0.1% difference lol

I've never seen finer than 800 grit at any Home Depot or Lowe's in SC; some don't stock finer than 600 grit. If you want the really fine grits for an unnecessary mirror finish, try your local auto parts store, or the automotive section of your local WalMart. WM typically stocks up to 1500 grit, and auto parts stores have 2000 or finer. Of course, IMHO, finer than 800 grit will get you a pretty, shiny finish but won't make any significant difference in cooling.

When I lapped my Sunbeam HSF (flat but not smooth copper base), I started with 400 paper and finished with 800. For my IHS, I only bothered with the 800.

edit: Old aquarium canopy glass (thin but well tempered) for the support base.

Autozone has Imperial wet/dry sandpaper in 220, 400, 800 and 1000 grits.

$3.99 for 4 sheets (~8.5x11) when I bought some yesterday.

I did 220 until the Ni was gone from the IHS (all down to copper) then 400, 800 and finally 1000.

After 800 grit I thoroughly cleaned the CPU and then with a sharpie pen I drew an X across the IHS.

The 1000 was only done for maybe 10 strokes (x4 90° rotations) to ensure the IHS was flat and even as I lifted the CPU and noted how evenly the sharpie "X" marking was dissappearing. Basically used the 1000 grit to plosh off the sharpie X, not for making mirror finish.

I did the same process with my Tuniq 120, except I used 60 grit to bevel off the corners so the copper baseplate wouldn't skip as much during the polishing.

Dropped my loaded temps maybe 5-6°C, but did not increase my overclocking at all as I am FSB limited on my DS3L.

i dunno if i did it correctly but i started with 1000 and stayed on 1000 lol

and this was the result http://s47.photobucket.com/alb...ew&current=lapped3.jpg

Nice IHS but waaaay nicer desktop wallpaper (3.2 Temp)

haha thanks for checking out the rest of my pics
