check your temps in istat, or if you could post a screen shot, that would be helpful

Is the computer itself hot, or are the fans just kicking up? What do you have running? Have you tried an SMC reset?

142 degrees f - fans @ 1800 rpm

182-191 - fans @ 6000-6300

4000 does not seem that high unless your temp is low and they just run and run for hours with you not doing anything

so, when you turn it on - without any heavy app running - the fans go to 4k rpm and stay there?

Try the following:

• Check if you installed a manual fan manager app, such as SMCfancontrol - If you did, turn the fan setting down and disable it.
• To make sure no other app is running, start in safe mode (hold Shift key while starting). See if the fans power up in safe mode.
• Reset SMC and PRAM: Reset SMC and Reset PRAM

hope this helps,

cheers!

i did use fan controller

i used fan controller when i first got my computer but then i had to reformat my mac due to sound issues and the fans were fine and within the last week they are going up.

that's not very hot, so I don't see a reason that your fan should be that high. My cpu is running 20C hotter than that at the moment, and my fan is only at 2000 RPM. Perhaps try resetting your SMC, there is a link for how to do so above.

Also, you can take a screenshot by pressing cmd+shift+3, or cmd+shift+4 to select the area you want to take the shot of.

The temperatures are OK - no problem there.... but, when you "reformatted" your mac and got rid of the fan controller, did you do a clean reinstall of OS X, or did you reinstall from a clone/Time Machine? Perhaps some fan control pref files are still hidden in your system.

Try what I suggested earlier: run the maintenence scripts (Onyx), reset PRAM and SMC... I think that'll help and will take some few minutes.

Also, if you want to reinstall everything, it's up to you it's your time.... BUT FIRST TRY RESETTING SMC AND PRAM...

 

[jordan123456789]

it did not work

so it didnt work so ill make a video and try and show whats its doing.

so... basic maintenance with Onyx and Disk Utility, starting up in safe mode, resetting SMC and resetting PRAM did not work...

Have you tried running Apple Hardware Test from your original install disks?

Finally, do a Archive and Reinstall of OS X...

If this does not work, take it to Apple...

I can't say my fan has really ever come on that I have noticed in my 13". How does one go about resetting the PRAM and what would be the symptoms leading up to a reset?

here it is

[freddyfingers]

my right fan is running at 5975rpm
the left side is running at 0rpms

its that normal?

I tried ramping up the cpu usage so says 85%-88% cpu usage and still get the same \right side goes up to 6005rpm left side 0 does the left kick on once things really heat up or does everyone elses computer have both fans running?

just tested

ok so i just tested the macbook pro for any errors and when it tests the logic board the fans go to the max. and then when its done testing the logic board it goes all the way down.

 

[freddyfingers]

mbp fans only one is running??

delete

 

[Pax]

Run Hardware Test, on your install disks (maybe that's what you mean by a logic board test?)
Does it show any temperature sensor errors? Faulty temp sensors can cause the fans to run very fast. Sensors are cheap to replace if that's the problem.

Open Activity monitor (found under /Applications/Utilities/ and sort by the CPU column (make sure you sort high to low). Check and see if there are any processes using a lot of (unnecessary) CPU time. Could be a thread gone rogue.
