I just swapped out my 5400 RPM hard drive (I have a 13" MBP) for 7200 RPM hard drive and noticed my MBP was running rather warmer than usual. Fan control is exactly what I was looking for; it allowed me to set the threshold temperatures for when the fan kicks on and shuts downs.

Is this a good program for my iMac 27 since it states it is for MacBooks? If not, how do I uninstall in? Do I just "remove form system preferences", and reset SMC?

Great software! It's just what I needed, since my MBP was overheating on simple tasks (like using Flash!). Heat was reducing performace and causing issues on network cards (wifi and wire). Now I can see videos on Youtube that couldn't see before. I've donated 10$

I installed it on my 10.6.6 iMac after failing to get smcFanControl to run. It shows up in the System Profile rather than as a separate file, which might be what's causing some people problems.

However, now my heat issues are WORSE. For low-demand stuff, it does help (i.e. something that might put me at 120F before stops around 110F), but high demand enters a feedback loop that takes the fan up to max and the temperature just keeps rising. I have to wonder if this is of a piece with how 10.6.x has broken heat control overall. Even setting the base speed to the maximum allowed 3500 rpm doesn't stop the runaway from happening. It's as if the OS knows something is trying to stop heat buildup and is determined to make MORE heat to counter it.

I prefer Fan Control over SMC Fan Control. I like the interface better, although it does seem that SMC Fan Control does have quite a bit more options.

I installed a fan control application on my wife's MacBook Pro five months ago and started having issues with the fans. It seemed to be correlated, although I think the fan was already going bad, and increasing the fan speed just broke the camels back. It wasn't any serious damage though: after opening the MacBook and re-lubricating the fans, it has been running just fine.

Installed it on a MBP 2.66GHz / MacOS 10.6.6. After installation there is no trace of a program. Nothing that could be opened or changed. Probably does not work anymore with new hard/software

Same problem.

Macbook pro 13". Deleted using fan control instructions. Also reset SMC. fan will not increase speed even at 70c. Reinstalled. and fan turns back on. This needs to be fixed.

Also, what happens if i want to reformat my computer? Will i need to install fan control again? Will the firmware be reset if i reformat my computer?

This is a great app!! Problem I have is that it will not ever set the fans to the max rpm of 6200 for my MacBook Pro 15" unibody. Seems only to get to about 5800. The red line on the graph in the system preferences control panel even indicates it will never use 6200.

Anyone got any solutions?

thanks!

Since I installed this program, my fans have been running loudly even at low speeds on my new white Macbook. After completely uninstalling it, 1800 rpm (and even 1500 rpm) are very noticeably loud, where previously at those speeds they were pretty much completely silent.

I was wondering if there is some way that I can restore my Macbook to the way it was before, since uninstalling it and then installing smcFanControl to restore apple's defaults didn't seem to take the problem away.

It still runs cool, so the fans must obviously be working, I just don't understand why they're so much louder now.

Any help would be appreciated. Thanks in advance!

I just installed Fan Control 1.1

Can someone explain why the Right Fan is at -1? Does it need to be on and how?

When I installed the software the temp of my MB was 136. It's now down to 127 with the left fan only.
