I didn't pushed my system because I belive it performs well without
overclocking. There are a lot of chances to fry the chip, and for this
reason I use my system at the frequency my manufacturer gave it to me.

It might be as you say, but I really do not belive that your chip will fry
at 44C. I never seen a chip that fried becasue the temperature was 1
degree greater that the one it supposed to work at. And I worked with a
lot of CPU's and motherboards.

I said, and now I'll say it again: I support the ideea of having very high
precission, BUT this is not the case for personal computer, this may
concern high-end systems that must run in a controlled environment at a
fixed temperature.
