How do I know why my fan is so loud?
All over the internet you find lots of more or less easy fixes for loud fans, such as: cleaning, replacing, or greasing the fan, renewing thermal paste, cleaning the interior of the laptop, etc. (not to mention several half baked software based "solutions")
The problem in my opinion is: There can be a multitude of different problems leading to the symptom of a loud fan. For example: bad heat transport from the cpu to the heat sink, a bad heat exchange between the heat sink and the air-stream used to cool it, the fan became solower over the years as a result of dirt, or wearout..) and so on and so forth. As long as you don't know where your problem comes from, you will probably treat it wrong.
I was wondering if there is any way to do a more sophisticated diagnosis. For example: is it possible, by looking at the different temperatures at heat sink / cpu, to tell what the problem is?
I guess this is a very relevant question, since almost every notebook gets noisy after a couple of years.
Thanks everyone :)
