#5 Can't get current fan speed

[Steven Heidel]

Program gives error "failed to read current fan speed." but yet running "aticonfig --pplib-cmd "get fanspeed 0"" works just fine.

steven@steven-PC:~$ aticonfig --pplib-cmd "get fanspeed 0"
Fan speed query:

Turns out my card only supports fan speed by percentages, here's a patch that works around that:

Hey thanks for the work-around, finally figured out what you mean - for those who dont know what to do:
1. download source-file from https://sourceforge.net/projects/amdovdrvctrl/files/C%2B%2B%20sources/
2. download ADL SDK from http://developer.amd.com/gpu/adlsdk/Pages/default.aspx and copy all files of ADL_SDK_X.X to AMDOverdriveCtrl/ADL_SDK
3. edit the file adl.cpp in /AMDOverdriveCtrl/src as described above
3. ./configure (needs to be set to chmod +x)
4. make
5. make install or make deb
(you need wxWidgets)

for AMDOverdriveCtrl.1.2.1.tar.bz2:
makefile needs to be edited as mentioned here https://sourceforge.net/p/amdovdrvctrl/bugs/4/#add9

"+" means add this line(s)
"-" means remove this line(s)

Hi, I have exactly the same problem with my HD6770. Using latest version of AMDOverdriveCtrl (1.2.4 to 1.2.7 tested). Is the fix included in the latest release versions already?

[Anonymous]

Cards which do only support fan speed in percentage should work with the latest version (fix has been included, tested using latest deb file with HD5870)

This is strange. My card supports reading fan speed in percentage:

$ aticonfig --pplib-cmd "get fanspeed 0"
Fan speed query: 
Query Index: 0, Speed in percent
Result: Fan Speed: 5%

but AMDOverdriveCtrl cannot use this information:
