Athlon 64 Winchester IHS (heat spreader) removal, update: done.

Has anyone removed it or seen it removed somewhere?

Will a Shuttle XPC HSF still make good contact?

Please post links or pictures or experience.

Update: a shuttle will still make good contact according to one poster who used a P-M in a sb61g2.
 
Not a smart idea. Oftentimes people who remove the heatspreader (on P4's or Athlon64's) end up with instable systems. Frequently the core ends up getting crushed.

Furthermore, heatsinks are designed for the extra height provided by the IHS, thereby making many heatinks incompatible with the CPU because there will be a gap or barely any pressure on the core.

Finally, it voids the warranty and is an irreversible process.

Its not irreversible but it is much easier to damage the core.

Do you have the same types of epoxies that Intel or AMD uses to attach their IHS back? If you try to reattach the IHS, it will never be 'as good' or make the kind of contact it does at the factory.

It's not opinions, back when the P4 started shipping with an IHS I looked into removing it around a few forums. Without fail the people who did this either cracked their cores, saw no improvement or had flaky systems within weeks.

But, hey, if you want to void your warranty and quite possibly screw up your chip, go for it! Just remember we warned you...
 
The new prescott cpu is adhered to the die. Amd has not adhered it yet, they still use thermal grease. As for the glue around the edges of the IHS, I don't know and neither does anyone else so far.

I fail to see how replacing the IHS--which apparently uses standard thermal grease--with something like Arctic Silver 5 will not help. So, if you have any opinions about that I'd like to hear them now 🙂.
 
I have a mobile a64 chip. These come w/o heatspreaders and run up to 9C colder than equivalent desktop chips. As stated above not all heatsinks will be appropriate. You will need to file down the posts by 1.5mm or so on a stock bracket, or use an appropriate sink (xp90/120, zalman orb, 948u, swifttech, alpha pal; others might also work but these listed do not require mods).

Core damage is a possibility but will be more of an issue with the large die of the .13 1MB chips vs. the .09 512k chips.

It's a worthwhile mod, but you will have to know what you are doing. And please don't raise costs for everyone else by trying to RMA the cpu to AMD if you screw up.
 
Well I did. I took a razor and carefully cut around the nickleplated copper IHS. it's just a thin layer of epoxy or silicone holding it on on the exterior. Warranty bwahahaha I never use them so screw it. I went from 2560 to 2650 on a 3000 newcastle.

BUT don't do it unless you have a waterblock as no A64 HS will work afterwords inside bracket.
 
Hmm. I had the opposite problem. I have a P4-M here, that lacks a heatspreader, and I need one. I have a friend with a Sager OEM'ed laptop, designed to use desktop P4 chips, except that the system's thermal design is poor, and it overheats after about an hour of usage. If I could swap him my P4-M, it would help a lot. I should try to obtain a dead desktop P4 CPU and remove the IHS, I guess.
 
I got my winchester, took off the IHS and used Arctic Silver 5 on it. The SN95G5 heatsink mounted successfully on the exposed die.
I am getting about 30C for the processor in the bios screen, and the fan is ~750-800 rpm.

BTW 12 Grams is a lot, get the 3.5 gram container of AS5.
 
are you supposed to take off the IHS??? to apply AS5...or do you apply it on top of the IHS and then place the HSF

Yes, get a 1962 or older penny that is pure copper. Go outside to the sidewalk and use your foot to carefully grind both sides down evenly. This saves alot of sanding time, now use 400-grit, then 1000-grit.

You end up with a mirror smooth copper penny that is about half the original thickness, perfect for using a Mobile P4 on a desktop board.
