Macbook Pro fans running high from startup

Question

Hi, I'm new to this forum, but I've been looking around quite a bit, both here and on other forums to find a solution to this problem, unsuccessfully.
I have a Macbook Pro, 15", 2007 model, Intel Processor. For a while now, the fans on the computer have speeded up to 6000 RPM almost immediately from bootup. Before today, the computer also overheated quite badly, topping at 96 degrees Celsius as monitored by istatmenus. Today I decided to open the computer (warranty already expired) and clean out dust and whatever else might be clogging up the fans. Using a high pressure air bottle I got rid of a few dustbunnies, no copious amounts, but something. After reboot, tthe temperature seems under control (CPU at 44 degrees celsius), but the fans keep running high.
I've tried out all the recommendations I found in other threads:
Reset SMC a few times
Reset PMU
Reset PRAM
There are no activities using up processor power, usage at the time of writing is about 20% per core with Google Chrome, Mail, Skype and some other stuff running.
I've uninstalled both SMC Fan Control and Fan Control apps completely according to instructions (removing library files etc.)
I've installed Temperature Monitor to see if there's any problem with the sensors. All the sensors seem to be working fine, except perhaps one: SMART Disk Hitachi HTS542525K9SA00 which is not giving a reading in Temperature Monitor.
However, iStat Menus gets a reading from the Hitachi Disk, saying it's currently at 35 Degrees Celsius. Thus, it seems as though the sensors are all online.
I haven't been able to do an Apple Hardware test since I haven't got the installation disc at home.
So... I'm basically out of ideas, and getting more than a bit frustrated since I'm using the computer for audio recording, which isn't much fun with fans blasting away at noisy 6000 RPM.
Does anyone have any idea what the problem might be and how I might be able to solve it?
Many thanks in advance

Answer 1

Yep, you could say that.
I had one of those screws unscrewed. Sure, by itself ))
but tightening it fixed the problem in my case.
Normally "nice guys" are lazy so it might be just some small unnoticeable thing.
If you were not nice with the "nice guys" you could expect more elaborate joke ))
If it is the case, If I were you, I would check termo pads, size of the screws, then tighten all up and that will be it.
For the size of the screws as for anything else you should try google.com or iFix.it
You don't really need to be not nice to be screwed )
Last joke of the "nice guys" here was replacing the trackpad connector. They told me that my MacBook is not booting and it is not the problem I've brought it for. Fortunately I have 4 Macs of the same model so it was quite easy to figure ))
Anyway, be safe, be nice, be a little bit paranoid in a sense of making connection of what happened in what circumstances.
Good luck.
