Some days ago my CPU fan began to make unnatural loud noise...
... time to search the fine mechanic oil can... this did help but finally all signes were set to change the CPU fan & cooler.
the new one did like a turbine jet with 100% all the time even when pc load was at 0.
So I decided to use SpeedFan 4.47 on my wn7 64 to create some profiles that in general only 40% fanspeed is used and at certain temp-steps the fan speed will rais up to 100%. so far so good.

now detecting a new panorama I observed that 8 cores at 100% load did result in a CPU core temp of >70 degree. not dramatic, but not normal, because the fanspeed did according to the set profile change to 100% but the speed of the fan itself did remain at unhearable 40%. there was no additional cooling.

reason: autopano.exe process gets started per default with priority normal and the same with SpeedFan. and autopano took the resources and fanspeed was blocked/overruled/whatever to use more resources.

solution: in the autostart group I did manipulate the start command of SpeedFan from:

"C:\Program Files (x86)\SpeedFan\speedfan.exe"


%windir%\system32\cmd.exe /c start "runrealtime" /realtime "C:\Program Files (x86)\SpeedFan\speedfan.exe"

now autopano start with normal priority and SpeedFan with priority "realtime" and SpeedFan gets now more priority and can handle the fan speed...
