Summary0002498: "Black Screen" hard crash of Radeon R9 Nano graphics card caused by SpeedFan
DescriptionSpeedFan causes a hard "black screen" crash of the R9 Nano as it goes through the process of probing the motherboard devices.


* The screen goes black
* The graphics card fan goes to maximum (100%)
* The machine is running, but the graphics card is locked up. Even a hardware reset won't restart the graphics card. Only a full power cycle will bring the graphics card back.
Steps To Reproduce1) Start s SpeedFan manually once the machine has booted.

2) The graphics card will crash before SpeedFan has finished reading the motherboard sensors and initialising.
Additional InformationI've been using SF (4.52.5782.52544) for several months successfully on this machine with an AMD Radeon 6950 graphics card.

After upgrading to an AMD Radeon R9 Nano card. I very time I log into Windows the card crashes within about 10-20s.

I have SpeedFan set up to start automatically from the Task Manager. After some testing I proved that SpeedFan was the cause of the crash-

1) By renaming the SpeedFan install directory (preventing SF from starting) I was able to get the machine running ok.

2) I tried moving the SF .cfg files to reset the configuration

3) Running SF manually still crashes the graphics card part way through the process of initialising SpeedFan.
