I currently have tried smcFanControl, Fan_Control, and Lubbo'sFanControl. At one point in time, I was using one that had a very simple layout, and made it easy to change your left and right MBP fan speeds at any time. Unforatuntely, I bought a new Mac, and no longer remember the name of the program. I then tried a few I had heard of, as mentioned above. smcFanControl nor Fan_Control allowed me or worked when attempting to manually change fan speeds. I had thought that in the past I had used Lubbo's Fan Control, although this time I tried downloading it, I could only find it as an .exe file. Any suggestions?
