Changing CPU thermal compound.

[MarkC1970]

I have just taken the heatsink of a v1.0, cleaned it up and replaced with MX4.  It seem to work OK but the heat sink is not clamped to the CPU at all well.  I can rotate it with no trouble and even rock it side to side.  Were the original thermal pads adhesive?  Were they 1mm thick and I need to now pack the clamp out?  Any thoughts?  Thanks.

Gpu can slightly move when clamped.  CPU should be pretty tight clamped down even with arctic mx 2/4.

The originals were pads i think. it's too consistently perfectly applied and tacky to be paste. it's normal to be able to move the cpu heatsink by hand after clamping when you changed the paste.

on the gpu is used glue like substance. no need to replace it.
