There's not going to be any snow in Sahara any time soon, I'm sure.
My CPU reached at 73 Celsius (the real core temperature, not the fake
external) this summer when the temperature outside and at home was at
its peak, playing "Far Cry", "Halo" and "Thief 3". I would be able to
drop the temperatures by ten Celsius with Zalman's toughest fan, but
I'm not really planning on it. My case temperatures were over 40
Celsius. No lock-ups on the graphics card or the processor. My
friend's CPU was at 56 Celsius with Epox motherboard, and funny enough
it had lock-ups from hell, which we finally fixed by setting the CPU
fan properly, after pondering for hours what the hell was going on
since the temperature weren't even near what I had. I believe the
Epox's BIOS showed false reports on the true temperature -- possibly
the external readings taken from the socket that just stopped at 56C
and in reality had reached 80 Celsius, which locked-up the system. It
took us a whole week to figure out it really was the CPU overheating
like chimney from hell. My Radeon 9800 Pro has been acting very well
even with the very demanding gymnastics and aerobic exercises with
"Deus Ex 2" and "Far Cry". It's been hot every now and then, though,
but the autumn is already knocking on the door and managed to drop my
CPU temps from 73 to 68C.
