cooling - Invalid (100°C?) CPU temp sensor - how do I disable throttling?

    I have a Quad core Q9550 processor, and it is displaying the temperature of 86 - 100 °C. I'm pretty sure that's not correct, since just a few minutes ago I have reapplied the thermal parse and right after that BIOS was showing 83°C. And a few other windows tools have shown up to 100+ C.

    The CPU is not overclocked, BIOS settings are default, and the cooler is default too. Windows runs fine at first, but after 4-5 hours it gets terribly slow - I suppose throttling gets enabled? If so, how can I disable it? I guess, this is a motherboard's (Asus P5Q-E) fault, so I'd have to replace it as an ultimate fix?

    Update: I've changed the cooler to another one and now it works like a charm. The previous one has been installed badly for 2.5 years (I am one stupid guy).

    There is almost no way these on-die temperature sensors can be inaccurate, and they cannot be disabled as they are vital physical safeties. Your CPU is overheating because something is terribly wrong with its cooling. Are you sure you applied the right kind of thermal paste? Are you sure the heat sink's fan is working? Are you sure the heat sink is properly mated to the CPU?

    I have a AMD X2 64 7750BE.

    My system bios show my CPU temp is at 64 degrees centigrade(64C). Is it too hot?

    MY CPU fan RPM is 2355. Is the rpm speed normal?

    According to a Google Search, a temperature between 40°C and 60°C is normal for this CPU, max is 75°C. But you could try to get a bigger heat sink.

    Btw, You mean Celsius. ;)

    This sounds like a normal temperature for a processor. If your really worried you could look into getting a third party heatsink for it.

    Between 40* and 75* is fine. I've had my computer run up as much as 85* before.

    It also depends on where do you live :-)

    During summertime my CPU is much hotter.

    So if you get 64C for air temperature around 20C, but you expect to have 40-45C during summertime, start looking for a better cooler.
