I can't pull the heatsink off!

[pentium]

I finally found a first generation socket 4 or 3 Pentium 1 CPU and the thing is massive! I really want to pull it's ugly heatsunk off and display the PENTIUM label beneath but this is where I am having real troubles.
First, the heatsink is attached without a clamp to the chip by a glue that looks like lite choclate. I would pry until it pops off but I am ascred of cracking the chip and ruining a piece of history.
Scraping it all away also seems useless because it is rathe stiff and I see at least two surface-mounted components on top if the ceramic chip.
Is there a trick or some chemical that can aid in removal?

And just if you are curious, it's at 66mhx and was made in 1992. It's no better than a 486 IMO.

stick it in the freezer in an antistatic bag (sealed tight) for an hour

I have working Pentium 60MHz with a board. It can be even overclocked to 66MHz

I'm gonna be away all day so is is that safe to the cpu?

Ooooooh. A whole 6 mhz?

a day in the freezer? never tried that long so cant recommend...

Re: I can't pull the heatsink off!

okay, so it's out of the freezer and ready for the next step.
I can't see prying it off, i might break the now brittel chip, correct?

Re: I can't pull the heatsink off!

fine, don't answer me.

Re: I can't pull the heatsink off!

how will the chip be brittle after only 1 hour in the freezer?

[pentium]

Re: I can't pull the heatsink off!

How?
I once broke a 386 when I was pulling it's heatsink off (except it was being done on a cold workshop). There was no warning and then *snap*.
I am just afraid I might do it again.

Re: I can't pull the heatsink off!

nevermind, I got it off.

I pulled the silkscreen with it!

Re: I can't pull the heatsink off!

That happens often when the glue is hard.

Re: I can't pull the heatsink off!

Oh well, I can't really complain.
I'm just happy the heatsink is off.

Yeah I have an Intel OverDrive chip PR66 (66Mhz) that could be OC'ed to like 83Mhz (upping the bus speed), but the POS Biostar mobo crapped out



Providing I could locate a decent/compatible motherboard for it... I suppose it'd be good enough to run a Linux firewall/router system

Re: I can't pull the heatsink off!

I was given a Compaq server over thanksgiving, has a pentium 66 (socket 5), with the heatsink fused to the CPU, no fan, 32mb of EDO SIMM's, 540mb HDD, no CDROM, and a floppy drive... It came from a family member who bought it new in 94, paying over $4000.00 for it. The case is absolutely mint, so its kind of cool to keep around for nostalgic reasons... I actually have DOS 6.22 installed on it, and I use it to modify BIOS's.

Here's the irony:
It ran 24/7 for about 6 years as his office file server, they never shut it off. The capacitors are fine, and it's 13 years old and was used heavily... Go figure.

I have two of those overdrive chips and the diagnostic floppy for them!
My 486 used to run at 33 mhz but a DX4 overdrive boosted it up to a good 100 mhz!

Another correction, The pentium cpu is not 66 mhz, it's only 60.

Not close to what I saw.
This one has a gold top to it.
Reminds me of it's smaller 75 mhz socket 7 version I pulled from a packard bell.

hit the more pics link.
and mine had the fdiv bug.
intel replaced it.

you want pictures?
sorry, My card reader is not in my computer at the moment.

Is this chip rare?
