I downloaded and tweaked around with Speedfan (v. 4.49), and the "Automatic speed fan" option seems to work a bit TOO good. When applying it, the CPU fan speed drops to and idle speed of ~650 rpm AND both the rear and front case fans shut down completely (0 rpm).
Initially I thought it was just because of the computer being just that; idle (with temps around 35'C), but then I tried applying a load to the CPU (rendering a file @ Premiere Pro) and even though the CPU temperatures raised to 50-60, the CPU fan wouldn't speed up. The fan should be capable of a speed of around 1300rpm (Thermalright TY-140).
The second problem I have is the intake and exhaust fans. As I said, they go completely motionless when "automatic speed fan" is enabled. Yes, this could perhaps be explained by the fact that my case seems to be in fairly good temperatures (~33-37) when idle, even without intake/exhaust fans running. But they don't seem to speed up when under load, either.
Also, when idle, I would like the front panel fan to be running even just a little bit, just to keep the hard drives (which are positioned in front of it) as cool as possible.
Any experienced Speedfan users out there?
Thanks in advance!
