Just installed a recently purchased, albeit "used", Intel Pentium D Dual Core 2.8 GHz 4MB L2 SL9DA CPU to replace the stock Intel C2D 1.86 GHz in my Dell Dim E520 (8 years old, but still going strong).
Boots up fine and is noticeably faster than before.
However, the thermal sensors don't work and I've tested this in a range of OSes (Ubuntu, Slackware, Gentoo as well as Windows 7).
In Linux, lm-sensors sees the appropriate drivers but fails to detect any sensors.
In Windows, the Nvidia System Monitor equally fails to detect the sensors.
I have never come across this defect before in my many years of dealing with these things. Obviously, without the thermal sensors, the CPU heatsink fan can work.
Has anybody else encountered this defect in a CPU before?
Is there any solution other than swapping out the defective CPU?
