Hi there. My Macbook Pro's fans are constantly running. It only started maybe a month or so ago. I have reset my PRAM, I have cleaned up the hard drive and a verified disc permissions. The thermal paste on my cpu's has been replaced. I have looked in the acitivity monitor, and it the green and yellow lines are spiking, but I don't know why. I do not see any stray activities happening. I haven't upgraded my software, so the setup hasn't changed. Any ideas?
Got a tip for us?

Have you tried an SMC reset yet?
Intel-based Macs: Resetting the System Management Controller (SMC)
To measure fan speed(s) and temperatures, use iStat Pro.
Btw, 2000RPM is the idle fan(s) speed.

iStat Pro is a good widget which will tell you
Theres also SMC Fancontrol, which used to allow you to control it, but i havent used it in a while and i dont know if it still works

Hi there. The fans are running at: Left: 6009rpm, Right: 5990rpm. I've done the SMC reset, nothing doing. And no, it's not when the Macbook is idle (asleep), but when I am working. Thanks for your responses.

what are you doing when they run at 6000 rpm mark? heavy editing,or light browsing etc,give us more info pls,
you may need to try reinstall of osx at the worst,although id start with a hardware test,can use install disc for this,google it.apple support forum has it too,

It doesn't matter how many apps I'm running, it still runs at that speed. I will try reinstalling osx and give feedback.

I did the hardware test, and I got the following error:
4SNS/1/40000000:Th2H-128.00. I googled it and it seems to be the thermal sensor. Now to find myself a guru in SA that will fix it for me tomorrow (nearly impossible - normal quote time is 48 hours
), as in ASAP. Hold thumbs they have the part. Thanks for all your input. I really appreciate it. I learnt a lot.

The fans come on after about a minute after booting up cold. Temps are: 21 - HD, 37 - CPU, 20 - Airport, 21 - Enclosure base, 47 - GPU diode, 37 - GPU heatsink, 31 - Mem controller.

I downloaded SMCFancontrol 2.2.2, but the application does't open. I am running OS 10.5.8.
I set the base speed to 1000RPM, Lower threshold to 40 degrees C and upper to 70 degrees C, and the fans are still churning. Am I doing it right?
try my settings of 2700rpm fan speed, lower threshold of 45C, and upper threshold of 70C. that keeps my computer running at 30-40C when im just browsing and keeps it very silent.
No, still nothing. I found apple core in SA, and I will be at their doorstep first thing in the morning, while they are still having their morning coffee.

i know that was probably a typo when you typed Apple Core but in a way that would be a great name for their retail stores!! haha

If your thermal sensor isn't working the fans will run at full speed to protect the computer from overheating since it doesn't know if it is overheating.
A misconnected thermal sensor cable or the sensor itself may be bad, it's cheap to replace and apple should be able to do it for you in a day or two.No amount of software tweaking like fan control and smc fan control will change that, don't bother.
MWAHAHAHAHA!!! Ok, they are called "The Core Group", but it's obviously a pun on Apple. http://www.core.co.za/contact.php

Just to keep you updated. I took it to the technicians, and they reckon I must have the Logic Board replaced (R6000 - donations welcome). They say that the guy that replaced the thermal paste, damaged it. "Report: Fails, 3 sensors, machine has been opened before, found a screw just sat inside on top of logic board. 1 sensor was not attached at all, just taped up with insulation tape, 1 sensor slightly broken near dvd drive and 1 sensor broken next to fan." Went back to thermal paste guy, who opened it up and explained that he doesn't know what they are talking about. I saw the tape, but apparantly it's for something that isn't needed. So here I am, dumb looking girl, in the middle, and someone is trying to con me out of R6000 and my fans are still running like it's the end of the world.
