? about hs/grease for those who have swapped cpus in the 6831's and the like

Picked up one of those $584 P-6831fx refurbs from a a couple weeks ago....great deal. Time to throw a t9300 into it. My question isnt about the cpu swap itself since that is straight forward and easy, rather the heatpipe assembly and chipset + GPU thermals.

I have probably just enough AS5 (used on other machines) left in the tube to do one more cpu. If the heatpipe assembly covers the chipset and the GPU, I would like to throw some better stuff on them too, in which case I think I will buy a tube of Arctic Cooling mx-2 since it is supposed to be just as good if not slightly better as well as non-conductive.

Anyhow...what are your experiences? Did you just do the necessary cpu? Or did you remove the pads or whatever is on the other 2 components as well?

I have seen mentioned that at least the chipset uses a pad. Is it one of the thick ones? Does the heatpipe screw down over those components or at least easily bendable to close the gap if it is a thick pad? Same goes for the GPU....I'm particularly interested in that one even if it is on a different hs/pipe since that is pretty much the hottest item down there and probably would shave a few numbers off the temp with better interface despite the obvious limited cooling capacity of laptop hs's.

Basicly would like to replace all grease/pads with better stuff while I'm changing out the cpu when it comes.

 

The GPU's actually quite a fair bit harder to reach than the CPU.

 

before you go for the gpu just game a bit and see what temps you get.
my gpu never gets above 70, so if its aint broken dont fix it.

 

thats what I'm gunna do since it appears you have to completely disassemble the laptop to get to it. I just figured I would slap some on to replace whatever original stuff was on there if it was on the same pipe/hs assembly as the cpu. The chipset I may still do though. I see a lot of mixed reactions about doing that in the different threads....some people saying it makes a difference, others saying stick with the pad since pads are generally used for clearance issues. I think I may do it anyways. I've ran into similar situations on regular desktop motherboards with heatpipe assemblies that use pads on the chipsets and power chips where it is sort of questionable if they used pads for ease or clearance reasons. Since all the areas had spring tensioned pushpins if not screws, I've gone ahead and used good non conductive paste instead of the pads and put small bends on the pipe on either side of the hs areas for a little extra downward pressure.....same theory as the tension clips on cpu heatsinks. Always worked great those times, with a noticeable drop in temps. In the end, its not so much that it's needed, but more of a you already have everything needed, and already taken apart, so why not kinda thing.
