I am, as I reported previously using a SMD LM335 away from the fan and held down with a screw and a small bracket and I get consistent .1 C. I do not think that I would get 1 E-12 over weeks when my lab has seen more than 5 C temperature changes if my temperature readings are not correct. Do not forget this was a quick and dirty setup, the final product will look more professional. Bert Kehren In a message dated 1/17/2012 12:19:44 P.M.

What is the fe5680 mounted to? just the heat sink or is there a thick metal plate. Also what are you using as a heat sensor. Is the sensor press fit to the heat sink or. I do remember reading about your temperature controlled fan but not the 0.1C part. I'd have guessed yo could only do about 2.0C with a setup like yours.
