Correct way to remount a heatsink??

[agarza]

I'm wondering if there's a particular order of remounting the heatsink onto the CPU/Northbridge by tightening the screws that hold the HS in a particular order.
Reason I ask is because I replace the thermal grease on the CPU and Northbridge with Arctic Silver 5, and first 2 screws I fastened were the ones to the left side, then proceeded with the little brackets that hold the heatsink into the T61 chassis.
I heard of reassembling the heatsink by tightening the screws on a star direction, but is this necessary on the Thinkpads?

Any one have done a thermal replace on their T60/T61. Not sure if the temperatures have dropped, I'm getting 76C at full load on Orthos with the CPU running at stock voltage.
FYI, my T61 has standard screen, so I guess it uses the same fan FRU as the T60 Std. screen, not sure.

"tightening the screws on a star direction,"
SOP on everything from car wheels to engine blocks, in order to get even torque across a part that is held down by multiple screws/bolts. I'd assume that logic will work for heat sinks as well. Not that it would be necessary--just that it would be more likely to give you even torque, for even cooling. (And presuming you used the thermal paste most sparingly in the first case.)
