Macbook Pro Fans running constantly

Hi there

The resolution: there's a fault on my motherboard. Motherboard needs to be replaced, as well as the bottom casing because it comes with sensors that the motherboard needs. AKA a LOT OF MONEY!!! Just thought I'd let you know and if ever someone else has a problem like this. Thanks again for all your help.
 
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.

And this is proof why amateurs should not be in their computers trying to do fix-its like apply thermal paste. Sorry OP, if you don't have the money than use SMC control and manually change your fan settings depending on your usage.

Don't you think I did that? That was one of the first things I did and it does N.O.T.H.I.N.G.! The software won't control the fans in this situation. And yes, maybe I am an amateur, that also happens to be very broke and doing the best I can. I'm sure I'm not the only one. And with this process, I've learnt lots, that counts for something doesn't it?

Well then there ya go. Didn't mean for my previous comment to come off as rude. But facts are facts. And you are right, you live, you learn...
 
1) Don't buy used, unless Apple looks at it and confirms that it still falls under warranty.

2) Don't have anyone but Apple screw around inside the computer.

3) Purchase Applecare.

I don't know who thermal paste guy is, but you took a huge risk when you presumably paid him to open up your computer and mess around in there. It's great that you learned something, but I hope next time you'll come on the forums and ask before jumping into things.

Well, now you have a computer to mess around with, so I guess that is some silver lining :)
 
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

Thanks for this hint, as my fan was constantly running at 5600 although I thought the MacBookPro was idle. It turned out that Kapersky Virus and Filemaker 12 kept the CPU busy (no idea why) at 50%, CPU temp was up to almost 70. After closing these two programs, CPU use dropped to some 3-8% and fan dropped to sustainable noise and speed too.

Currently there are zero viruses affecting Mac OS X in public circulation, but there are other kinds of malware existing, that can infect your Mac.
But as long as you don't install software from unknown and untrusted sources, you are safe, as malware needs administrative permissions to run successfully, which means, you need to install the malware yourself, it can't install itself (one of the reasons, why a Mac OS X virus hasn't appeared yet).

fans running constantly

I swapped heatsinks in my 2.3ghz 17" macbook pro. It was a success aside from the fans running at high speed. The new heatsink ($4 incl. shipping) came with a heat sensor attached. It was the culprit. I swapped the old sensor back in and now have a near perfect computer again.
I am thankful for these discussion boards as they allow me to get by without a lot of "professional" help. I am a firm believer in doing things for myself and encourage others to give it a shot.
