RE: Dell 7567 Inspiron 7000 FAN SPEED CONTROL
Same experience with ATG5404.
Dell have replaced the heat sink and fan and even the back cover and the main items replaced twice. No change
They advised that it was working within limits but the unit is often too hot to touch the back of whether off on glass, raised surface etc.
Here is an article I have read that may help....
Please let me know how you get on. I was using the SpeedFan program to monitor the temps and fan speed but as the article explains it cannot set the speeds unless the Dell way is disabled.
