NEOPROLOG  This is the best fan control app ever on mac. I have also tried SMCFancontrol and FanControl, all off them overwrites apple's defaults and closes auto increment of fanspeed.

This is what i'm looking for, never try anything else.

thanks to developer.

JACKWEB  I've tried this for a few weeks, and it does what it says! =)

My MBP has never been cooler, and I just realised that most of the time the fans were running at 1000 RPM or just below. Now I've set them to 2000 RPM like the default on the new C2D's.

Thanks for combining the other fan speed controls into one easy little interface. And what a bonus that it doesn't need to do any hacks, just a standalone app.

SNDTECH  the MBP fans are designed to run at a max speed of 6000RPMs this will speed will occur with apple's own fan settings if the machine is under a heavy processor load. your fans are no being damaged by this program, its dust that cakes onto the blades and causes the fans to go off balance. Applecare will cover this issue and replace your fans for free.

COUGARBLUE  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.

SMPDIGITAL  Why can't I run this app on my iMac core duo? I think it should be available to all intel macs  
(Version 0.8.2)

JOESCHISA  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).

JACKWEB  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.

FAHLMAN  Now that we have that all straightened out I'm going to give it a try. As I said in my previous post I really like the GUI. Thank you for taking the best features of two open source applications and combining them to offer us this application.

KKILLIAN  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.

HENDRIK HOLTMANN  Yes, it is based on parts of the source-code of smcFanControl. I am the author of smcFanControl and most parts are 1:1 copied. It copies parts of Fan Control (another fan app) for the automatic control mode as well. This is ok, cause both apps are Open-Source and it's a welcome addition to the existing apps. But in my opinion the author of iCyclone should at least mention the other authors in credits he uses source-code from.
