HoSS, The oscillation of the relay may be from the temperature sensor, but Jeff will have to answer that one. Our SDC does not have that problem. http://www.mp3car.com/store/product_...products_id=66
However, you are incorrect about the low temp feature being useless. It is quite useful. Why? Because, when temperatures are too low, the lubrication freezes in moving parts such as your hard drive and fans. This can cause your hard drive not to spin up, and your fans not to spin, which will result in hard drive and fan failure. Hard drives were not designed for extreme cold. According to the hard drive manufacturers, the standard 3.5" hard drives should not be operated below 5 deg C (41 def F).
