The Amd recommendation is max 63 celcius for my cpu which is now at 75
degrees celcius. Its not even a hot day here? IM gonna shut down soon just
incase it burns out. The only reason im not so worried is the mobo temp app
goes from yellow to orange to red and im still only just in the yellow. I
asume red would be the time to switch off im hoping if my cpu got that hot it
would switch off automatically. Im suprised as when i bought the cpu i read
reviews of temperatures half what its at. The stock cooler seemed to be
quality i'm not sure buying another one will make any difference? Any
recommendations for good coolers?
Both current AMD and Intel processors, have THERMTRIP. If the processor
gets hot enough (such as what happens when a clip breaks and the heatsink
falls off), the computer will shut off with no warning. You could be in
the middle of doing something, and it'll just switch off. There won't be
any dialog box on the screen, saying "bye bye". That is because THERMTRIP
is wired in a pretty direct path to the power supply.
That is what protects the processor from burnout.
To improve your cooling
1) Check all filters on the computer are dust free. I removed the filters
from the front of my computer, so that the filter would not become
clogged. If I didn't do that, I'd have to check the filters monthly,
because they would clog quickly.
2) Make sure there is sufficient intake vent space, on the front of the
computer. If there is a big fan on the back of the computer, it cannot
exhaust hot air well, unless there is some good sized intake vent area
on the front.
3) Make sure the BIOS automatic fan control is disabled, so that the
fan will run at full speed. Some fan control algorithms are not
correct, and lead to poor cooling performance.
4) Vacuum dust out of the CPU heatsink fins. I did this the other day, using
an adapter kit that plugs into my vacuum cleaner hose. The wand on the end
of the adapter, is about 1/2" wide and 1/4" thick, and can get between the
fan blades, to clean the fin area. I got a 5C improvement in temperatures,
once some of the dust was removed.
5) Check that the heatsink is still firmly secured to the socket. On some
Intel LGA775 systems, the plastic peg system doesn't hold the heatsink
that well, leading to variable cooling performance. I would expect the
AMD sink to be a little better. If the heatsink has been removed several
times for inspection, then cleaning the surfaces and applying fresh
thermal paste, is recommended.
