On the application of thermal paste, I've actually thought about this
for a few days, and decided to comment...if you are not overclocking,
ignore this because the thermal pad supplied will work OK, but if you
know the value of a cool running processor you want to do everything
you can initially, you don't want to go out and buy yet another 80mm fan
down the road.
Most of the aftermarket heatsinks, esp Thermalright, are pretty rough
and could use burnishing. If you can see machine marks, you need to
do this: I use a 4000 grit really fine sandpaper which can get it shiny,
can't have any visible marks where the sink contacts the CPU.
I use the 90 percent alcohol (from Walmart actually) and not the 70
percent, which has oil added, rub it with something lint free,let it flash
dry at least ten minutes, and do the thin spread on both heatsink and
CPU, just very thin, and too much is bad and not enough can be
a disaster. I do this to insure 100 percent of the CPU will have the paste,
Which is Arctic but the other brands do work OK. Any touch of the
fingers will leave a minute amount of oil on the part, and sometimes
the brand new CPU's come dirty (had one)
I've done this and carefully noted temp differences, one current rig runs
at 30 percent overclock with CPU fan running at 2500RPM's, no case
fan whatsoever, and 42-46C usually. Like I say, not that big a deal
unless every degree counts to you, like me.
