removing 5 year old thermal paste from cpu

[apt403]

hey.

i have a really old intel cpu i just salvaged from a dell, im making a keychain out of it and am in the process of stripping it of its pins, theres some thermal paste/tape thats been on there for 5+ years now and wont come off, how do i get it off? ive tryed everything from a sponge with soap and water to steel wool, nothings working.

crappy pics, but see what i mean?

oh and anybody have a clue to what kind of cpu this is? i cant figure it out, since there are no markings on it, and i just took it out of the board and started to hack away at the pins, no time to see what it was.

thanks in advance.

Have you tried 90% rubbing alcohol? I think that might be a Pentium III

hmmm, rubbing alcohol, never though of that, thanks. i probably have some around here somewhere, but i'll have to look.

Also a razor blade could do it, watch your finger though!

Rubbing alcohal is the offical compound remover.
It does take elbowgrease and for sure that is a pentium 3 600mhz... why u using that old thing?

According to the original post, he's making a keychain out of it.

Out of curiosity, how can you tell from that picture that its a p3 @ 600 MHz?

BTW, Nokia IP650 appliance FW's still use P2 / P3's...

It's a Pentium 4, but for the socket 423, the first one for the pentium 4, maybe a 1.4 to 1.8 Ghz processor...
The pentium 3 processor is different...

Great guess, 2006 - 5 years = 2001, about right =).
Had a S423 P4(never boought one, I am smart =) that I took from an old system looks like that...

I think comptia rep was on a wild guess =)

You mean used to (not sold anymore), but yeah, they don't much processing power or disk I/O, as I recall most of them had 2.5" disks. If you're doing heavy encryption, the add-in crypto card is the way to go.

And end of life, end of support life.... But still working quite well.

 

[apt403]

ive tryed a razor blade too, but that didnt work. i found some 90% rubbing alcohol though, and it worked like a charm, thanks!

 

[CompTIA_Rep]

if you make it into a key chain, you cant use it anymore as a PIII processor. Its 600mhz I know this because I toook a guess.... and guesses are beter then facts.

really? wow i had no idea, i though a cpu could still funtion with a huge hole through it and a total lack of pins...

yeah, i just removed the last of the pins, and the aluminum heat spreader is nice and shinny, now i just have to decide where to drill.

 

[CompTIA_Rep]

I hope you saved those pins so you can resoder then back on when you want to use it again.

And instead of drilling, which has the potential of ruining the processor (which forces you to buy a new one), May i suggest a clip on processor ring?

 

[apt403]

all the pins are scattered on my floor and stuck under the keys of my macbooks keyboard. and what do you mean by "clip on processor ring"?

 

[CompTIA_Rep]

You know, like a clip on nose ring.

Anyway, sounds like you acidently lost control of your pins, but you can order more for resoddering.

i think i'll just take my changes with crazy glue and paper clips.

 

[CompTIA_Rep]

Dont be bry, give me the processor and i will put it back together.
Go ruin something of no historic value.

 

[apt403]

if you send me a new cpu to turn into a key chain i'll send you this one so you can try to fix it, has to be something good though.

 

[dasickninja]

This is getting kind of home buildish, I'm not sure if this even belongs in the CPU section anymore
Would a lapped till gleaming Celeron D suffice?

Depends, is it a socket 775 or 478? I would take a C2D as well, doesnt even have to work, as long as its all there physically its fine.

I wish there was some place i could go where they sold old cpu's for like a buck each, thinking about buying a few off newegg, but even the cheapest ones are there still like $20, kinda steep for something im turning into a keychain.

 

[shinigamiX]

I want to lap some old LGA775 CPU and etch "Core 2 Extreme" on it - see what my friends think

 

[dasickninja]

LGA775. It still works so I'm probably not trying hard enough

 

[apt403]

i was searching around ebay for bulk cpus and found this there old pentiums from what i can see in the pic, only would cost me about $20 after shipping.

edit:300 old proc's. i would be bussy for a while if i managed to get all those.
