[QUOTE="JollyRogerBay, post: 1630729, member: 340611"] Hello everyone, I recently bought a Mid-2007 Mac mini from my university surplus store. The machine is a 1.83 GHZ Intel Core 2 Duo model with 2 GB Ram and came without a hard drive. When I first tested the computer without a drive, it was extremely quiet, but after I followed iFixit's guide to replace the hard drive and installed Lion, the fan is extremely loud. The high fan speeds continue while starting up, and the speed lowers when the computer is idling on the desktop. If I try and do anything such as use Safari or update the machine, the fan speed goes back up. I have done research into this issue, and several people have stated that this is the result of not correctly plugging in the hard drive temperature cable. I have, however, ensured that the cable is properly installed. In addition, I know that the fan currently runs lower than if I start the computer with the cable completely unplugged (I have tested this). This leads me to think that the cable is indeed intact and properly connected. The first hard drive I installed is a 2.5" that used to be in my Mid-2012 MacBook Pro before I upgraded it to an SSD. I then installed another I had lying around, and it produced the same issue. Additionally, I am currently running smcFanControl to keep the fan speeds off 5000 RPM, and have observed a temperature around 40-54 C. I have also already tried resetting the SMC (unplugged for 15 seconds, and plugged in for 5 before being powered on). On top of this, I have run an Apple Hardware Test that returned no errors. Besides the fan issues, the Mac mini is running extremely well. Has anyone else encountered this problem when installing a new hard drive or have any ideas what could be happening to this mini? Should I ignore this and keep using smcFanControl to idle my computer or is there a fix? I'd much prefer having the computer take care of the tasks of temperature regulation; it's quite distracting having to do it myself. Thanks in advance. [/QUOTE]
