Yes the 11 W/mK are good enough.
Here are two great threads.http://forum.notebookreview.com/panason ... -mods.htmlhttp://forum.notebookreview.com/panason ... -pads.html
My original posts on this subject..
Actually the cf29 uses a putty that comes in a sheet form. I opened a parts cf29 and I took the thermal material off and rolled it into a ball.
Fujipoly is what I came up with to use.
150 means 1.5mm XPE is the material.
The XPE has a thermal conductivity of 11 W/mK. Which from what I found out is really high performance. Thermal conductivity of 6 W/mK is considered high performance.http://www.frozencpu.com/products/11654 ... 8c487s1289http://www.frozencpu.com/cat/l3/g8/c487 ... Page1.html
From my research, I found that the 6wmk putty pads are considered high perf. Considering that we are not overclocking these things, 6wmk should be more than enough. I think it is more of an issue to use the incorrect thickness or several different thermal materials at the same time. If someone uses a 6wmk putty then why use paste?
I used the 11wmk because I wanted to try it. It has the same color and consistency as the OEM putty found on my CF29E. I used some 6wmk .5mm pads under the heat rails and 11wmk 1.5mm on the 2 chips. The bottom may get a tiny bit warmer now.
I feel that there is probably not much difference between 6wmk and 11wmk(or 17wmk for that matter)on these machines. Be sure you use the correct thickness and application techniques. If the 6wmk works for water cooled overclocked I7's etc..then I figure it's more than enough for our 1.2-1.6ghz Pentium M's.
Panasonic designed an entire cooling system. I don't feel that the exact wmk specs for the thermal putty are that critical. As long as it is high perf and the correct thickness is applied properly I don't think the magic smoke will come out.
Since the original is a putty, and rolls it up into a ball and can be flattened back out, why not reuse it? I tested it on my parts machine and it crushed properly when I reseated the base of the unit.
