The issue still happens with 260.19.12. Given that it's about two years since the issue appeared and there's has not been _any_ effort to get it fixed, I guess it's the last time I bought a notebook with an integrated nvidia chip.

To all people who have this problem: have you ever updated BIOS for your laptops?

Some BIOS updates make GPU fan never stop/rest to save GPU from overheating/burning due to a notorious problem with the bump material. And if I'm not mistaken you cannot do anything about that.

I have updated the BIOS, but IIRC it was after the issue appeared. Can't tell for sure after so long.

I have the latest BIOS for my HP Pavilion dv9500. One of the BIOS updates did turn the fan on at a low speed all the time, but it is unrelated to this problem. The maximum fan speed for 5 minutes after boot/resume problem began with a specific version of the NVIDIA driver and it still there in the latest version. I've given up hope of them fixing the bug at this point and don't plan to buy an NVIDIA product again.

It's most likely a combination of new NVIDIA releases and somewhat buggy BIOS'es (if it were solely due to NVIDIA drivers, then all users would experience this issue) that causes this issue and it's really sad no one at NVIDIA has tried to resolve/reproduce this bug.

I asked NVIDIA to start a public bugzilla years ago but they don't want this kind of publicity/transparency/openness.

I have the same problem with dell latitude d630c notebook (using the latest bios revision A11). I used to work around that problem by using the legacy version 173.14.28 of the nvidia driver. However, this version of the driver is no longer compatible with the latest kernel versions as far as I can see. So I'm forced to live with this annoying oscillation of the fan speed in the first 5 mins after xorg has been started. The problem seems to be that the nvidia driver wants to set a higher fan speed because of the GPU temperature being above 60 C, whereas the BIOS lowers the fan speed because the CPU is only at about 35 C (There is only one fan in the laptop). I can disable the BIOS fan control by hitting Fn + Shift + 15324 followed by Fn + R. However this setting has to be made again after each cold reboot of the laptop and I think that it is a bad idea to disable the BIOS fan control since the CPU could maybe overheat when its usage is high.

For me it would be actually less annoying if the fan speed would remain constant but the noise is frequently changing between high pitch and low pitch making it sound like an alarm.

Any hints on how to solve that annoying problem would be welcome.

Best regards

I solved under windows using rivatuner nvstrap, my HP DV6723EL with 8400M GS now have a QUADRO NVS 290
Using quadro driver after softmod with rivatuner fan noise is stopped, temperature and performance are the same but with this trick i can't use suspend mode and hibernation
under linux seems there's no similar solutions at the moment

Default Re: Fan running full-speed for 5min

Using i8kctl (Debian package: i8kutils), a program which provides fan speed control for dell notebooks, I was able to work around the oscillating fan speed issue by running the following shell script in the background which frequently imposes a minimal fan speed and thus prevents the bios to lower the speed of the fan:

Code:
#!/bin/bash
modprobe i8k

min_fanspeed=2

while true; do
    fanspeeds=(`i8kctl fan`)
    if [[ ${fanspeeds[1]} -lt 3 ]]; then
        i8kctl fan - $min_fanspeed >& /dev/null
    fi
    sleep 0.1
done
With this script running on my Dell Latitude D630C, the temperature of the GPU (Quadro NVS 135M) drops from above 60 C to about 55 C. I find it much less annoying if the fan constantly runs at medium speed than the oscillation between low and medium speed that it does without running this script. However, according to i8kmon the temperature of the CPU also drops to about 28 C, which may be too low. I don't know whether there is a problem with this low CPU temperature. I heard that the hard disk drive can be damaged if it is too cold, but this should not be a problem since in the Dell Latitude D630C, the hdd is not directly cooled by the fan.

Best regards
