Possible heat problem on CPU

A friend of mine is having trouble with his PC. Periodically it
freezes up completely. My guess was an overheating CPU. I suggested
he install Motherboard Monitor, which he did. The CPU is at 60° C at
boot, and goes up from there. At around 70° C or somewhat above, the
machine freezes up. (This is an Intel processor, by the way.)
Clearly, then, it seems that the CPU is overheated. I told him to
check the fans. All fans are turning, including the CPU fan, which is
moving fast enough to be a blur.
I then thought that maybe the connection between CPU and heatsink is
bad. I asked him to check the temp on the CPU and then touch the
heatsink fins. At 70° C, they should be scalding hot. He says they
are only just warm. Conclusion: There's inadequate contact between
the CPU package and the heatsink, probably because there's too much or
not enough thermal compound, or it was applied improperly, or the
heatsink was mounted improperly ... or perhaps there is no thermal
compound at all. The heatsink and fan are third-party (not boxed CPU
versions), and the computer was assembled for him by a small company
that builts PCs to order.
I've suggested to him that he remove the fan and heatsink, remove any
thermal compound, then apply new compound carefully and remount the
heatsink and fan. Do all of you agree that this is a good idea? The
compound is cheap. It's true that the processor could be damaged by
removing and remounting the heat sink, but I figure he has nothing
else to lose at this point (the next step, I think, would be a new
processor and possibly a new motherboard). What do you think? Am I
missing any other possibilities?
