After months nothing happening, imirkin have send out a ping:

Now over a half year later still nothing happened. Could someone take a look at this?

Thanks

The patch you're talking about has been merged for a long time now.
Comment 2 caguduzexi 2017-08-23 22:51:41 UTC
I saw after your report that the patch is been merged into the kernel since 4.11-rc1. Every later kernel should not let the gpu-fan run at 100%.
I tested now a fresh linux live iso with kernel 4.12 and have 100% gpu-fan the whole time. The fan speed did not change from the 100% when the computer is been turned on. NV43 and NV42 GPUs are been tested and none of those slows down.
If there is some other live linux iso i should test, i would do that.
Comment 3 caguduzexi 2017-10-03 16:10:06 UTC

NV42 Quadro FX3450 Vbios dump

Here is a VBIOS dump of a Nvidia Quadro FX3450 card. I got it by running

Comment 6 caguduzexi 2017-10-03 21:26:16 UTC
Thanks to mupuf. He find out that the reason for not working fan is:

nouveau 0000:08:00.0: therm: parsing the fan table failed


This have been displayed by adding "nouveau.debug=debug" to the kernel boot line.
Comment 7 Martin Peres 2017-10-10 20:42:37 UTC
Sorry for delay. I wanted to pick it up this weekend, but failed. I will try again next week end!
Comment 8 caguduzexi 2017-10-23 22:49:46 UTC
I bought extra for this bug an Nvidia 7900GS card. It have a bigger and powerfull fan - that is running the whole time at 100%. Kernel 4.13.9 . Because its such a powerful fan, you have to speak louder to other people in the same room when you are both next to the computer...
Should i do something to help fixing this bug?

We have now the next year. There was tons of week ends in between your post and now. Nothing happened. One of the fan have failed because it ran the whole time at 100%. Now i have to buy a new fan.

When would i be able to use the computer like expected?
Comment 11 caguduzexi 2018-08-12 22:30:54 UTC
I tried now Kernel 4.17.14 (the latest kernel recently).
The error is still there! Please help fixing this! I dont know what to do. Fans are spinning at 100% the whole time.

Please retest >5.0, and also report back in bug 107447 perhaps.
