Chosen Solution
Gang, I figure why not DIY my new mini so I got 8G of memory and a OCZ Agility 200G SSD drive. I have put these in several older mini’s. Ok So I replaced the drive and did all the stuff put the DVD install disk in and formated, partitioned and transfered the OS. The problem is the FAN is running full speed. I tried the SMC reset by removing the power cord and pressing the on button for 5 seconds. I reset PRAM no luck… I opened the $@!$ thing 3 times and cannot see anything wrong. There is one thing I cannot figure out. On the Toshiba drive I swapped out there was a little PCB and a two wire connector on the front. Not sure if that is it… does not seem to be anything required. Help? Thanks gordon
Just did a little research and it turns out that there are 2 Thermal Sensors, one on the sata connector and one glued to the drive. If you have eliminated these sensors it might cause your fans to blare at full speed being that the temperature is not being monitored. Read this post…. http://forums.macrumors.com/showthread.p… One of the PO’s speaks of these sensors.
If you get all the connectors back in place and the fan still runs at max speed… First, try smcFanControl: http://www.eidac.de If that doesn’t fix it, solder a 1/8W 2kΩ resistor between the two center wires on the 4-wire fan connector (leaving all the wires connected). This will drop the fan to about half speed, still a bit audible but nothing like the full-speed cyclone.
