Cleaning Heatsink on 8887

Thread Starter 
Recently the fans on my 8887 were running nearly constantly. I removed the heatsink and cleaned a LOT of dust from the copper fins. When I went to clean the chip and heatsink, and apply some arctic silver I noticed there's a shim of some kind taped to the bottom of the heatsink. I'ts rather rough and wouldn't allow a nice close fit, I would imagine. I removed it, cleaned all the surfaces and applied a little thermal paste, and reassembled with the shim back in place.
My questions are... What is that shim for, and why is it rough? Could it be removed? Is there an app to monitor the CPU temp?
Thanks.

Yes, there is an app, but NO, it won't monitor the CPU temp in an 8887. Several of us have tried (search the forums, don't have the threads at hand at the moment) but have found that the 8887 does not have thermal sensors that are READABLE by an app.

I think this is one of the links you were reffering to.

Thanks for the temperature app link. I hadn't bothered looking for that part. I'm more interested in the shim part of my question. Does anyone know what that shim is for? Heat spreader, electrical isolation? Can it be removed?

could you post some pictures of it? im interested in this.
maybe some lapping would give it a better contact with the cpu

The heatsink and chip are smooth (not lapped). It's this "shim" that's kinda rough. I'm all reassembled now but if I can get some answers from some people regarding this thing, I may take it apart again. We'll see.

What you are referring to is the TIM (thermal interface material) carrier. It has phase change "stuff" on either side of it. It looks kinda foilish. It is safe to remove it.
