    How to remove the small heat sink off the cpu

    I found a quick way to remove the small heatsink from cpu's. Taking them apart and selling them seperate you will make more money just a matter of how quick you are and what your time is worth. Every once in awhile you will get a heatsink with gold underneath the cap.(added bonus, usually from some P4 and celeron D) I will attach some pictures one was previously posted by jghilino showing the gold cap. Basically you will need a descent sized magnet to hold the cpu in place so that you can hit the heat sink downward to remove it.

    Below is a price comparison using Ewasted prices for cpus hopefully he wont mind.

    $6.40lb Green Fiber with Heatsink - Pins

    11.4oz*6.40= $4.56

    $16.00lb Green/Brown Fiber without Heatsink
    4.4oz*16= $4.40

    #2 Copper(tinned 14awg or larger/paint $2.25/lb
    Im not an expert on what grade this would be considered they are solid cooper that is tinned I believe.(if Im wrond please advise)

    7oz* 2.25/lb= .98

    4.40+.98= $5.38 seperated
    VS
    $4.56 whole
    Thats .82 cents more from 14 cpus approx 6 cents more per cpu not alot more profit for the work but it is pretty easy and can be done quickly. If my values for copper or fiber cpus are low than it could be worth it.

    It's usually just dried up heat sink grease that's holding them fast to the heat sink, so I use a flat blade and start sliding between the chip and sink, tap it if you need to.

    I have done that in the past this is just a quicker method for me and it makes it easier to remove the caps that have been expoxied on along with grease in the middle. Just curious what do you sell the caps as? #2 copper? thanks

    Just curious.... What about Pentium 4 pinless procs with the heatsink soldered to the cpu? What happens to the sort and the price then? Thanks.

    Good question, never had that one answered by ANY buyer. But from what I know the pinless P4 is not worth refining unless they are mixed in with other material. I would think that removing the sink should bump up price but only a buyer would have that answer

    I was able to put them in with green fiber a few months ago for one seller. You can always ask. I was using the heat gun to melt the solder before lifting the cap off. It wasn't worth my time.

    Thanks for the quick reply, I'll try asking a person I know locally that your response made me think of and I'll reply back but it'll be a couple of weeks before I run to town again. I'm more limited to mail in recycling since I'm usually down in between chemo treatments (that's mostly when I go to town), but that's more for off topic thread. I'll ask next time I'm in town and get back. Thanks again!!!

    Thanks I'll probably do it if I can get someone to buy it separately, just for something to tinker with, thanks again!!
