I guess if its reading the temperature from the socket rather then the chip then the sensor may be bad.
come to think of it the first time we booted an went into bios the CPU2 sensor was reporting something silly like 25C.
Hmm, has anyone had any experiance of faulty temperature sensors?
I'm not convinced that the sensor is faulty though because as you say I did feel the heat sinks after a few minutes running and CPU1 was fairly cool and CPU2 was hot.
the heatsinks we're using are vapochill things, liquid filled with 3 verticle tubes in a fin array with a fan on the side.
