When you reapply the paste, clean the heat sink. Dust is an excellent
Does the system fan have three wires? If there are only two, the fan lacks
tachometer feedback and will always read '0'. I have seen many systems that
have a motherboard supporting fan speed reporting (I think all modern ones
do), but lacking the slightly more expensive fan that actually provides the
I also would suggest disabling throttling and TCC on non-current systems.
11 will FINALLY disable these by default. (I've been beating this horse
since at least v7 and I am amazed that it was not dead!) While this might
not help, it will leave TCC at its default of "AUTO" for thermal control
instead of attempting to make it a power management tool.
