RivaTuner Linux equivalent?

@Linux Guru's: Is there a RivaTuner equivalent for Linux (I'm using Ubuntu64), or some app that can be used to adjust the speed of the GPU fan?? - things are getting a bit toasty ...!

 

Not sure where you'd get the Ubuntu package from, but what you're looking for is called nvclock. 'nvclock -F ....'

Code:

       
       -F, --fanspeed speed
              Using this option you can adjust the duty  cycle  of  the
              fanspeed. The value you can enter can be a delta like +10
              or -10 which increases/decreases the fanspeed  with  10%.
              Further the value can be a number like 20 which would set
              the fanspeed to 20%.  Further  if  your  sensor  supports
              automatic  (temperature  controlled) fanspeed adjustments
              you can also use the value ’auto’ to switch back to auto-
              matic  control.  Note  that  in  all  cases  the  (final)
              fanspeed should lie between 10%  and  100%.  A  low  duty
              cycle correspons to a low fanspeed.

              Note  that  the  duty cycle is NOT the fanspeed. The duty
              cycle controls the percentage of time  in  a  fixed  time
              interval  in  which the fan is ’on’. By choosing a higher
              value the fan is enabled a larger part of the time  which
              results  in  a  higher  fanspeed. Changing the duty cycle
              from 20% to 40% doesn’t double the noise or fanspeed.

I also understand (but this is secondhand rather than from personal experience) that the latest nVidia BETA drivers 190.xx allow fan control from the nvidia control panel. But obviously not a lot of use for folding purposes where you're stuck on the 180.xx series.

 

Thanks JackOfAll.
Installed nvclock, then had to do a bit of fiddling in the xorg.conf file to enable Coolbits, then on rebooting, I've got control of the duty cycle which I've bumped up - temps dropped nicely
Lets see if this particular GPU now behaves nicely ....

 

Couldn't get the old GPU to sustain running 24/7, so popped in a GTX 260

Q. If you have two GPU's, how do you target a specific one with 'nvclock'?

 

Code:

        -c, --card number
              Most systems only contain only one videocard. On  systems
              with  multiple  cards,  this option can be used to select
              the card to overclock.

 

Oops - missed that one on the help list
One final question - there's option to clock the GPU and Mem - what about the shader?

 

There's no way to get at the shader clock, on the fly, at runtime. It's a case of using a VGA bios editor if you want to do that. Dump the bios, edit the shader clock, and flash it back.
