wrong cpu fan??

[ashly]

i need alittle help here....i am new to this so please forgive my stupidity...just recieved my p3 550e 100mhz fcpga oem processor w/o fan so i ordered a fan it was a vantec fcpga h.e. cooling fan for coppermine cpu....how does the heatsink and fan mount to the processor?...i know the flat surface of the heatsink goes to the flat surface of the processor but on that side of the processor it really isn't flat has the bump of the cpu there so heatsink doesn't lye flat and the clip that is on the heatsink is not going to attack to the cpu either...i have some thermal paste but i guess i need some instruction on how to put this together...guess i should have gotten the retail...is there another part i need? thank-you

I am guessing that the heatsinks for FC-PGA coppermines attach the same way as socket 7 heatsinks. If they do, then there should be a springy strip of metal running through the heatsink. This actually clips onto the socket that the CPU goes in (you attach the heatsink after the CPU is in place). Have a close look at the socket and you should see protruding bits of plastic on two opposite sides of the socket, these lugs are what the springy clip thing on the heatsink uses to hold the heatsink on to the socket. If you are unsure of the mechanism, just try and attach the heatsink without the CPU in its socket to familiarise yourself with the mechanism.

When you are familiar with how the heatsink is going to be attached to the socket, you are ready to put the CPU in. CPUs are sensitive to static electricity, so either use an earth bonding strap, or ground yourself on the computer case (have the power supply cable plugged in and turned off, so the case is earthed). The CPU has a specific alignment, so have a look at the pins on the bottom of the chip and you should see that in at least one corner, there appears to be a pin missing (no corner pin). Then have a look at the pin holes on the socket and you should see a similar arrangement. Lift the lever at the side of the socket to the vertical position and drop the chip in. NO force should be required to seat the CPU in the socket - if you have to shove it, you probably have the chip aligned incorrectly and will bend/break pins! Now push the lever on the socket back to its horizontal position - this makes the socket grip the CPU pins and makes a good elecrical contact.

Now the CPU is in place, smear a very thin layer of thermal paste over the back of the heatsink in the position where the bump in the CPU will correspond to when the heatsink is attached - use your finger to do this.

The bump in the CPU is actually the CPU core - Inhell have started to expose the core, presumably to get better heat transfer by having the heatsink in direct contact with the silicon - this is electrically isolated (coated with some resin stuff), so don't worry about placing the metal heatsink onto the core - there are no exposed circuits there. The core is the only bit of the chip that generates heat, as the L2 cache is incorporated onto the core (in those chips).

Carefully clip the heatsink in place and that's that!!

also u might want to take a close look so that they really have contact

since
the coppermine´s core i so small
the sink will slide on it
and sometimes loose contact
also the core is wery fragile so DO not use force when mounting the HS

and also do u have a slotcket ?
if not ul need one
if your not on a fcpga motherboard that is

Errrr... yeah, that's a good point, skywalker!! I'd like to see someone get a PGA370 chip into a Slot1. Could you go to the shops and get me a bag of chicken lips, oh yeah..pass me the glass spanner and left-handed screwdriver on your way out http://www.sysopt.com/forum/smile.gif

Ashly, if you're not sure what these slocket things are, they are used to convert a FC-PGA370 chip into the Slot1 orifice. Here's some piccies:
