The App does what it says.

I was looking for an altrnative to FanControl since it acted quite strange on my MAcBookPro.
The automatic adjustment of fan speed corresponding to the temperature is the feature the macBook needs to run cooler, because by default the fans kick in at 80 C, which is already quite hot.

Unfortunately on my computer the automatic- mode seems to work randomly: it would ignore the given lower threshold and right away speed up to 2500- 3500 rpm, which under normal use is already quite noisy.

I think i´ll switch back to FanControl and just deal with it´s random freakouts.

I've used iCyclone for about 3 months on my MacBookPro. I found that it did indeed reduce the heat coming out of the bottom of the MBP when I was holding it on my lap or using it in bed. I normally had it set at 2000 or 3000 rpm in manual. When I did a startup, regardless of my previous settings in would go into Automatic mode. That brought about a serious problem all users of iCyclone need to be aware of. The program had my fans running at 5000-5400 rpm which destroyed both fans. I cannot use the computer until I get an expensive repair. The only warning was a sudden rattling noise which got louder over 2 minutes then the fan died. One fan died a day after the first, when I thought I had disabled the program. Unfortunately I did a restart, the program started in Auto mode, killing the fan in less than 5 minutes.
My advice DON'T USE iCYCLONE in a MBP or risk killing the fans. They are NOT made to operate at 5000+ rpm which iCyclone will push them up to.

Tentatively wish this was available for powerbook G4. Mine was sent to Apple twice for "lower RAM memory slot failure" which seems to be due to overheating the solder connection between the RAM chip and its IC board. But then I would wonder if increased fan speed goes beyond what the fan may be designed to handle (i.e. wear and tear) over some period of time (I have no idea).

Something strange is happening, the disk image is being downloaded as an archive with extension .bz2

I initially tried to unarchive the thing, but ended up with a non useable dmg file.

Then finally thought to change the extension to just .dmg
Now it worked, sorry maybe I'm the only one with the problem, I know it's happened on one other occasion when Safari attached a .zip extension to a download.

For whom that can be irritated that i take the idea from smcFanControl of Hendrik Holtmann (and also the principal code) and think that i don't metion him , i'm sorry. I make my thanks to him in About panel of program in credits (i have also make my credits to others developer form whom i take ideas and code). For the missing credits on site i ask again excuse but i take all this in my free time and i'm still warking on it, so have a little of patience and in this days i'll take all the site up.

thanks.
