Dell precision m6400 noisy fan

Hi folks,

I have a Dell Precision M6400, with which I'm generally very pleased.

However, the fan(s) is (are) very noisy.
Dell recommended using a can of compressed air to blow out dust. Did this & seemed to get a very short-lived improvement.
Della also recommended updating the BIOS. Did this & had no effect.

I understand that there are 2 fans? A video card one & a processor one.

Has anyone else had similar problems on this or any other laptop / desktop replacement please and if so, any ideas on how I can resolve this?
The noise level is distracting & tiring.

Many thanks in advance.

Philip

Same issue here. Except for one Precision 690 workstation that my wife has, every Dell I've owned gets noisy very quickly, and they use fans that you can't get from anyone but dell (which is understandable for a laptop, but inexcusable for a desktop). If you're still under warranty, just make them replace the fans about 20 times. They'll never clue in and correct this bad habit until it starts costing them more to leave it broken.
