Dell Precision m6400 chipset heat

post #1 of 3
Thread Starter 
Anyone worked with Dell m6400's?

I have I8kFanGUI running with settings:

CPU slow fan at 75 / fast at 85
GPU slow fan at 65 / fast at 75
memory slow fan at 48 / fast at 52
chipset slow fan at 50 / fast at 54

Just watching videos and surfing and never firing up a game the peaks are:

CPU:34
GPU:46
RAM: 46
Chip: 54
HDD: 46

Ambient room temperature about 29 C. (It was 35 C at 9pm outside tonight)

Every time the fans are coming on to top speed it has been set off by the Chipset and I did try setting the top temp to 60 (which worked fine on the Dell m6300 because other devices would always start the fans first) but had a thermal shutdown event at about 58.

Is this normal behavior for this notebook?

There is a hot spot close to the screen just right of the Dell logo but the pictures I've seen that would be the GPU and it's component parts..

Opening it and cleaning seems on the agenda.

Dell's manuals didn't see to be of use on the m6400 and I hung up after waiting 45 minutes to talk to their techs.

Edit: It shipped with an underpowered 130W PSU and once the 210W proper PSU gets here and the CPU kicks into top modes I bet the problems get worse.

With this setup the CPU is SLOW untill 75c then starts to spin faster, same with GPU only at 65c.

If you set it like this you will allways have tempratures around 75c cpu and 65c gpu with some system load.

I think a better setup would be,

CPU slow at 50c fast at 80c
GPU slow at 45c fast at 70c

With a profile like this the FAN will make more noise, but atleast it keeps the components cooler.

The chipset is the controlling factor. Chipset is sitting at 52 C all day long so the fans are always at slow and much of the time the fans are on at max speed. I'm trying to find out what safe levels to set the chipset triggers at.

But I'll remember what you said as a general case for other machines.
