ihs removal

[Geomon]

I am toying with the idea of removing the heatspreader from my 57FX but have heard some horror stories about resistors also being removed too.

Does anyone know a good method of how to remove the ihs or have any tips to help me.

I have a busted 3500+ that I will practice on first.

use a modelling knife (scalpel type) dont go in too far kinda make a line in the knife at the 5mm deep area of the blade and just stroke the seal gently and slowly. do all 4 edges and corners first - if it dont comeaway gently and slowly cut a couple of mil deeper and repeat until it comes off.

Or send it to shigsy to get it removed

tip for ya :

Stick it in a freezer bag seal it (double check you seal it to prevent condensation) shove it in freezer for an hour or so take it out and then teh seal is easier (although it may sound like it isn't) to break using a hot knife

I've only seen this on AMD 64's as the XP's came open core anyway but would this work on a P4? I've seen a pic on Artic Sliver's website of a P4 with the IHS off. Is there much of a temp drop and what issue can i come into?

Edit: Taken from AS5 website.

''The photo to the right shows how the pressure from the heatsink base spreads the compound and also shows a P4 with the heat spreader removed to show the location of the actual CPU core that is the source of the heat.

While the CPU core on an Athlon64 is slightly larger than the P4 core, it is still much smaller than the metal CPU Cap that covers it.''

It's only really usefull if your running Phase cooling because it allows Direct Die contact to the head of the Phase. You wouldn't really notice any difference on air or water apart from the more chance of cracking the core, due to most of the hold downs being designed to put as much pressure as possible on the ihs so it touches the core. Seeing as your running air, I wouldn't recommend it, but it can be done to P4 chips yea with much more difficulty.

I would of though AMD 64's being hard as resistors are right on the inside of the IHS from what pic's i have seen. I guess it's something i won't bother with tll i get a hot CPU thats Phase worthy. Thanks for the info, learn't something new

 

[boardy]

Your right, the AMD64s can be a pain but the P4 cores are SOMETIMES glued to the ihs to prevent people from removing the ihs. I know the 775's are and some of the Pressys, dunno bout the Northwoods but I wouldn't like to be the one to find out personally.

It be a skt 478 if it was to be done as i'm not really looking at making that big of a jump just yet

Thats exactly how I was thinking to do it, I would make a line on the blade so I never go to deep. What I am thinking to do is practice on a 3500+ and once the ihs is off I could then messure exacly how much of the blade can go in.

Who has does this and what gains where had? thx guys.

Well first question is how much more of an overclock have you gained from the chilly1 r402 mod?? this will give some kind of indication also what stepping is your fx??

The stepping is poo . The Chilly is performing great and I got about a 100mhz overclock with the mod.

The cpu is not at all a good overclocker and it may be better to just sell it.

I know there have been great results from most from removing the A64 ihs, even on water/air people have seen good temp drops, think i'll do mine before i whack the mach 2 back on

 

[fatty]

I think that standard mach2 will give you a good indication a modded one will give you maybe a little more removing the ihs may give 50-100 tops I need to test mine under a cascade to see what she will do I can do 3600 non stable at the moment under my prom I am sure it will go a lot higher under a cascade

Here is one same week as mine under dry ice -75 evap so not that low

 

[Geomon]

Yeah that cooling is in another league to a chilly mach. Is that a week 16 57fx?

I can get 3.6 but it a milion miles away from being stable. At 3.450ghz it is 12hour prime95 +memtest 86 stable.

Hmm, is I do the ihs then I will gain a small overclock but lose value on the 57fx, if I sell her now I will get more for her and could then look out for a better stepping..:? Hmm.

What do you think guys?

 

[boardy]

Fatty is that screeny under LN2?!?

We hit that on a 57 under single stage :S Couldn't go any higher with LN2, infact it didn't like LN2 at all and bummed us out all the time.

Geo, I think you may gain a LITTLE on the FX with it topless, as long as a good job is done of it and the ihs isnt damaged, cos u can put em back on i believe.

Boardy is correct that the IHS if correctly removed can be reseated quite easily (well easily to shigsy ) - but SD cores are quite fragile so be mindful of that.

LN2 and FX SD cores best temps to hold it to is between -75 and -100 degrees AFAIK - if you go too cold it craps out unfortunately.

The last (only) good thing that Intel have over AMD is there is (AFAIK) no cold bug with current Intel CPU's.

 

[fatty]

The screeny is of a week 22 top on under dry ice it doesnt boil as low as LN2 oh an there is a week 16 on the bay of flea for £500

just for the guys taking the ihs off an athlon 64 here is what you need to watch out for underneath. Watch for those transistors (or whatever they are lol)
