You can but there are better alternatives out there. There won't be a large difference though so it doesn't hurt to use it if thats what you already have.Can I use Arctic Silver 5 on a laptop CPU. I have only used it before for desktop CPUs?
I need to put thermal grease on an AMD Turion 64 X2 RM-72 CPU. The laptop is HP Pavilion dv4
....
It might be possible. I've tried to put it on laptop chips before, but they used a pretty thick tap/pad and so without it, there was a gap in between the cpu and heatsink and the chip would overheat (nice thermal design, right?).
Ed: Just saw the pic, that should be fine, just don't put too much. Is there any reason why you want to replace the grease that's already there? Are you having overheating problems?
