Do you feel heat when your PC is turned on and running hard? Of course
you do. The whole machine heats up. The CPU under load heats the
machine so the RAM and drives and everything else heats up also. Not
as hot as the CPU, but it heats up. So I might agree with you - the
RAM might not be 'hot', but it would certainly be 'warmer'.

I'm not suggesting that this would cause a normal DRAM stick to go
bad, but only that if he had a very marginal bit of RAM that it might
go out of spec...
