Hmm, OK. Can you confirm manual fan management works as expected? I have just tried on my nvc4 and automatic fan management brings back my fan speed to 40% from the 100% set manually. As for your question about fan management being done by the hw or software, it is always scaled in software (either in an RTOS running in the card or in the kernel driver). In the fermi family, the first chipsets were actually using a dedicated hardware chip for fan management (ADT7473) but your card is not one of them. So, in our case, we run the code in the linux kernel but it will be moved to the RTOS when I'm done pushing my patches to fix timers and when I take the time to write the code for fan management.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
