I am not a Dell employee
What I don't understand is if this is BIOS problem in 8400 series, as somebody suggested, why doesn't it happen to all 8400s? Mine (BIOS A03) is fairly quiet except when the video card fan revs up.
Has anybody with noisy fan run Dell diagnostics on memory. I vaguely remember someone posting that noisy fan problem turned out to be bad memory module and replacement cured the noise.
im getting a reading of 68.0 degrees celcius. but since this never seems to change i doubt that it is a valid reading from the thermal sensor. i have been trying for some time now to find a program that can read the thermal sensor on the 8400 motherboard but they all fail.
also i have had my fan changed 3 times and this has done nothing. having my motherboard changed did reduce the noise from my fan but has not in anyway solved it. i live in ireland so this i a global problem it would appear.we also have to rely on the indian tech support :).
what i would advise is to use a better thermal interface material than what dell uses, there thermal paste comes pre applied to the underneath of the heatsink ( all technicans i have had did not clean off the old paste before adding new heatsink ------this can cause more thermal resistance between the cpu and heatsink causing the cpu core to heat up more because there is too much paste there--so make them do it) .try something like artic silver 5 thermal paste and use isopropyll alcohol to clean off the old paste beforehand.
