Questions about boxed PIIIs w. SECC2 and OLGA

[Snoopy]

Does anyone know what thermal material did Intel use for the boxed (Intel heatsink and fan) Intel Pentium IIIs in the S.E.C.C.2 packaging that uses what Intel calls "Organic Land Grid Array" (OLGA) to attach the heatsink directly to the processor die?

Is it paste or tape? Is it thermal glue? If it's paste, how it compares with something like Arctic Silver II?

If anyone removed such an Intel PIII heatsink, how hard is to be removed? Is any danger that there may remain residues from the thermal paste or tape on the die and it has to be scraped in order to apply effectively some good "after market" paste (such as Arctic Silver)?

i don't know about OLGA but I owned SECC2 version of P3. It came with the Intel's thermal tape that is applied between the CPU core & the factory HSF.

Is it paste or tape? Is it thermal glue? If it's paste, how it compares with something like Arctic Silver II?

Tape only. no glue. and no comparison to any of Artic Silver series. ASII is by far better than the factory thermal tapes or paste. ASII is the best one currently. =)

When i first removed it, i used a set of pliers and ripped it off. and worked flawlessly. :eek: and it was not too easy, but managed it. :p However, there's instruction how to do it properly without worrying about damaging the chips on the slot1 cartridge. If you want it, i'll post it here..

Thanks \(^0^)/

If you can post those instructions I would greatly appreciate.

I have a 550 (@100, 512KB L2) and I read somewhere that Intel started at some point to use thermal paste for the Slot 1 PIIIs (since 550 if I remember correctly).. But maybe this info was incorrect. On what PIII did you remove the Intel heatsink?

So, what chances I would have to destroy my CPU or cache chips when removing the heatsink compared with the benefit of ASII..? I don't want to buy another processor now.. (btw I found a Slot-1 100 FSB PIII 850MHz, just 256KB L2 cache but supposedly more effficient, thermal power is just 2/3 of the 550 power - ~20W compared with 30W for 550 - retail for $250 Canadian.. but still a bit too expensive for 2 year old technology).

The main concern with removing thermal paste is cleanig the residual enough to get a good clean install of the Arctic Silver II. The is no danger in removing a HSF that is using AS beyond the normal concerns with taking it loose from the socket. There is an AS epoxy but that is for ram and chipset applications. The chip that you are refering to is way to expensing for it's technology. Check out www.pcprogress.com for reasonable prices on older cpu's. An 850E seccII oem is $142.00 us while a retail is $184.00 US.

.. Intel's gave me a dried out thermal pad .. heh!

Epoxy is not meant to be put on your CPU ... Its for the GPU's and Ram stuff .. :)

I wouldn't really care what Intel put I would change it with either Artic Silver 2 or Radio Shack thermal paste.

Hi Snoopy

Here's one of the sites for removing the HSF P3.. click Here (http://www.overclockers.com/tips33/)

I removed my P3 800EB Slot1 HSF from its cartridge a few years ago.

Yeah those P3 550's are Katmai processors, before the Coppermine P3's released. Those Katmai@ 512kb L2 runs at its half of the processor's speed. The Coppermines run its full speed at 256kb of L2 cache. They also run faster and more efficient and overclocks better than the Katmai. You're right, the Katmai 550 does have very high thermal output.. The P3 850 starts at around 120 USD but don't know if they ship to Canada but check around.. =)

As for the removing the factory HSF on a P3 slot1, if you follow the instruction by going to one of the sites I posted, the chance damaging your chips is very low. The way I did with mine is obviously stupid.. very risky hahahaha. so I don't recommend the way I did with mine. good luck =)

The method is really easy I can explain it in 2 sentences:

Take your case screw and a screw driver . Locate the four holes in the back of your slot catridge thingy, put the cast screw in the hole and push with a good force and it'll simple pop out.
