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

I have the same problem with my Dell M6400, have you had any resolution to this problem?

On my Dell Precision M6400 I noticed the fans were runing much noiser than previous months. Yesterday the unit started to power off at weird times and I suspected it was thermal related as the heat from the bottom was almost too hot to touch! I ended up taking off the back panel (remove battery + two screws, panel slides to the front of the unit and easily comes out. It exposes two fans and two heat syncs. I used compressed air can and blew out in both directions and some pretty large chunks of dust came out. But that back on and then removed the keyboard, 1 plastic bezel and four screws. Blew out the unit, CAREFULLY with LESS air force than the fan & heat sync.

Replaced keyboard, four screws, plastic bezel and whalla, no problems since; and fans are back to a noise level that reminds me of the first 10 months of ownership. A few of those dust chunks were big enough that they probably were blocking critical cooling paths and thus the thermal shutoff.

Hope this helps.
