WTF?????????? man. These things are not staying for nothing.

and this SH#$ http://www.performance-pcs.com/cata...ge=product_info&cPath=46_58&products_id=22980 isnt helping either? '


What are I doint wrong? I'm cleaning the chip b4 applying

Edit: you have to let them cure.....

No curing,, I would be suspect of the cleaner you use. It must evaporate completely. A final wipe of the surfaces with iso alcohol 90% or above has always worked for me.
I prefer using the arctic silver adesive http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=46_58&products_id=227 for sinks like that but it's pretty much permanent. If you want to remove them you may ruin the board.

i use those mosfetsinks on my motherboard and they stick pretty good.i used alcohol and then a pencil eraser

Under the AM3 ready heatsink. What are these 12 chips? to the board and how hot will they get. are these enzotechs a must?

p.s I apologize for my first posts anger. I'm dealing with heavy medical stuff and this is not my computer and I should not have let my anger spill into these forums.

Are you applying pressure while you are waiting for them to cure? What exactly are you using to clean the surfaces with?

You can use some super glue on the corner of the heatsink and the VRMs. That's what I've done in the past, used regular ceramic paste and a tiny bit of glue.

A very very very small bit of it only on one corner, no more otherwise you wont be able to remove the heatsinks. Should you want to remove the heatsinks you just twist them off rather than pull.

how long to cure/?

how long to cure/?

I would say an hour for a strong enough bond.

When you apply the heatsinks, push downward for 10 seconds or so. The way that tape works, it has a residue adhesive inside of the tape. You need to essentially squeeze (wet it) out.

What are you using to clean the surfaces?

mrbarton, this is quoted from your first link,

These tapes are tacky pressure sensitive adhesives loaded with thermally conductive ceramic fillers that do not require a heat cure cycle to form an excellent bond to many substrates. Only pressure is needed to form an excellent bond and thermal interface.

As Jim pointed out you need a little pressure, ten seconds is all it takes. It does stick better over time but it will not harden and be solidly attatched, If you pull, it will come,,,
