Tualatin IHS removal. (Kony)

    Hey Dave (and crew).

    Well that Tualatin I mentioned that I'd glued the HS onto with Zalman epxoy?
    I ran a razor blade around the IHS and eased it off, it came away no
    trouble. One thing I found interesting, there was quite a gap between the
    core and the IHS, filled with thermal compound. Probably 2mm or more. That
    can't be good for heat-transfer.

    I then put the HS into a hot oven for a half-hour and tapped the IHS with a
    screwdriver and it came off the HS fairly easilly. Gouged the (aluminium) HS
    a little, it's a lot softer when it's hot. Thankfully not in an area where
    it makes contact with the core. I then 'lapped' the HS with some 600 grit
    wet & dry sandpaper (wet) on glass to remove the remaining epoxy. It
    actually came up a lot smoother than it was originally. Plus it's a lot
    flatter now, it was quite bowed, a good half-hour of elbow-grease.

    I don't have a board to run the Tui in at the moment but when I get one I'm
    just gonna run it bare (no IHS). I really didn't like the way there was such
    a huge gap between the IHS and the core, certainly can't be good for
    heat-transfer.

    Thanks for the URL and the idea, I now have another CPU I can use when I can
    find a cheap enough board. It's a Celly 1.3Ghz.

    Cheers,

    Yep, after seeing quite a few chips sans their IHS, it's clear that a user
    with attention to detail will have a better interface without the IHS,
    providing of course that they have a halfway decent heatsink... but for a
    Tualatin any old POS 'sink is usually plenty good after it's lapped.

    I'd be worried about the oven though, if the localized heat was too high
    compared to the thermostat it might get hotter than intended, harm the
    chip.

    It's good to hear that the IHS came off without any damage... I probably
    would've taken a hacksaw to the 'sink and cut out a chunk of the bottom.

    good ... no damage to the CPU base (PCB); my friend did not have that
    luck!

    Sure not! I did not wanna remove for myself that IHS but resolved a
    problem my way .. :) , see my site ... check my mods too .. :)

    >I then put the HS into a hot oven for a half-hour and tapped the IHS ....


    thats nothing; I put my Tuallie on the pot & than on the stove! see on
    my site this updated under comp/..CPU Burn-in ... :)))

    > I then 'lapped' the HS ... it's a lot
    >flatter now, it was quite bowed....


    I did it also on IHS ...

    If you have enough gutts, you can try lapping the core itself too ..
    :) (some guys did it, but its a risky business)

    be carefull not to crack the edges of a CPU core; put some foamed gum
    washers at the edge of a CPU (like AMDs have) to prevent that when
    mounting a HS!

    Be carefull that in any case the HS does not fall off during operation
    /crack of a holding plastics on s370 socket!/, since IHS helps
    delay-ing the thermal runaway of a chip to engage its thermal
    protection at IMHO 125°C shutting it down ...

    sure not, but that gap is not equal on all samples, some have been
    just assembled worse (depends on in which Intel´s factory was done &
    boxed are generally made better)

    Maybe I wasn't clear, I put the HS in the oven, still attached to the IHS
    but *after* I'd removed the CPU.

    I think it was because the CPU was stuck to a HS. I could only get the blade
    in dead straight, therefore it didn't dig into the CPU substrate.

    Yeah, I've seen a site that gives instructions on how to do it. I don't
    think I'll bother. <g>

    The site Kony gave me mentioned this. I have some double-sided foam tape
    that I'm going to try using. It is a little thicker than the die but I think
    (hope) that it will compress enough to allow good contact between core and
    HS. It is quite 'spongy'.

    Thanks for the tips.

    Naw, you were clear... 'twas prior to the AM coffee, i was not clear

    LOL, any excuse to cut up a heatsink... the scraps are infinitely cheaper
    than ready-made mosfet 'sinks

    Foam tape, provided it's open-cell, should compress plenty, though you
    should be ok without any tape... Coppermines survived. It was mostly the
    Athlons that were such a problem because of the extra tension AMD spec'd
    for the heatsink clip, and I suspect it didn't help that the ceramic
    carrier was completely inflexible.

    Thanks. Yeah, I already tried fitting it in a socket and fitting a HSF, just
    for the hell of it. It was Ok. Shame it wasn't a board that could run it.
