Summary0002076: when linking system fan to nVidia GPU temp, fan will stay off until GPU reaches 50C then goes to 100%
DescriptionIf I specify that a system fan be controlled by the nVidia GPU temp, the fan control will ignore the GPU temp until it reaches 50C, at which point the fan suddenly goes to 100%. On the way down, the fan shuts off at 50C.
Steps To ReproduceAdd a system fan to control. Specify that it be controlled by the GPU temp. Observe that, not matter what you do with the GPU profile, it always turns on full blast at 50C on the way up, and that it goes from full blast to off on the way down.
Additional InformationThis happened with a 9800 GTX and a GTX 650. The fan works fine when associated with a motherboard temp sensor. It's annoying because I want the system fan to start venting more air when the GPU heats up, but not full blast at 50C. That's just silly - and noisy.

Did you check CONFIGURE / TEMPERATURES? Most likely, you should fine tune the WARNING level set for video card temperature reading.

I think maybe you misunderstood the notes? I am trying to control a system fan based on the temperature of the GPU. I am controlling the system fan with the "new" method, using the GPU temperature. I have it set to the default temperature profile (30 - 60 C) as you can see in the screen shot I am posting.

According to the screen shot, the fan speed should go up gradually starting from 30 C until it reaches full speed at 60 C, but instead it suddenly jumps to 100% at 50 C. (The other temperature profile has a similar range.) At any rate, it is set to max of speeds, so I should expect that the fan % should be determined by the temp profile with the highest % for that temp.

But don't worry - you're the developer, not me, so I will check to make sure the warning level is set correctly. Maybe that is the critical piece of info that I am missing. :)

Haha - it was my stupidity. It worked. In retrospect, I never thought to pay attention to it, since all my other temps never came close to their warning threshold!

Thanks for the advice. Close this thing before I get too embarrassed.

Perhaps it should be renamed something like "threshold," instead of "warning," as "warning" implies notification without action.

A cop doesn't pull you over and "warn" you with a ticket. ;)
