Temperature after applying new thermal paste.

Hi,
I just renewed the thermal paste to my X200 tablet. Now, the idle temperature reads like ~45-50 C, with a little load (10%-20%) ~55-60 C. Is that normal? I feel it is a little high.
I applied a dab of "X"-shape Acttice Silver 5 on both CPUs (including the one with a thermal rubber), and then screwed them tightly. I have little experience to change thermal paste. Can anyone tell me is there anything wrong? Thanks.

So... is that warmer or cooler than it was originally? You did check, right?
In any case... that temperature should be fine.
Notebooks tend to run a little hot anyways (prioritizing quiet over cooling), and the internal parts are good to upwards of 90C.
You might have a bit more paste than is necessary (I use the 'grain-of-rice' method myself- instructions should have come with the paste and IIRC the heatsink plate is flat), but it should be alright as-is.

Sorry, I did not check the original temperature range before disassemblying. I guess I did used a little bit more than a grain size of AS5 thermal paste. Maybe I shouldn't apply any thermal paste on the original thermal rubber's surface. I didn't replace the thermal pad (rubber), as I am not sure of the size and thickness to buy. Now the CPU temperature is around 65 C with 30% CPU load which is a normal usage of my daily work.

Hi
That sounds a little high IMO - the X200 Tablet uses Low-Power processors. I have a W500, and my idle temps can get as low as below 40C, with Intel Graphics (fan turned off)
My W500 have a CPU temp of 46C and GPU (ATi graphics) of 52C currently, while im writing this, with the fan on 3000 RPM. I have Skype open, and 5 fans in IE. So something is off IMO (and something is off in my W500 too, while we are at it
)
The thermal paste have to be Applied as a paper-thin layer, just covering the surface. The thermal-pad can be replaced by a thin cobbershim to get the temps even lower, i did that in my W500.
I hope you'll find a solution.
Best regards

Thank you for your reply! I may try to apply the thermal paste again in the future. I guess the "grain method" works better...
