|0001557||SpeedFan||Fan control||public||2010-02-21 18:48||2010-03-08 05:50|
|Platform||AMD Athlon XP 2800+||OS||Windows XP 32bit||OS Version||SP3|
|Summary||0001557: Speedfan - video card fan stopped permanently?|
|Description||I've been using Speedfan for years too change fan speeds on my Gigabyte Nvidia 6800GT (Winbond W83L785R) video card, but after closing Speedfan 4.37 then immediately reopening it again, a few days ago, it seems to have permanently? set the W83L785R chip to a PWM value to low to startup, and the fan is now stopped dead at all times including startup POST.|
I can see the fan's LED light's glow *very faintly* at 100% and go dimmer as I decrease the % so the fan physically seems ok.
I have shutdown the PC and unplugged it overnight - no effect.
Have run PC with 4.37 un-installed - no effect.
Have installed GigaByte vturner2 fan/OC controller - no effect (just reports 0 RPM and can't speed it up)
Have installed SF 4.40 - no effect.
Video card is otherwise fine, I just can't play any 3D games because card gets to hot.
|Additional Information||This has happened before, using SF 4.33 but came right, speeding up by-itself over a couple of days, but it's been 4 days now with no sign of life apart from the LED's.|
The Fan needs "Reverse PWM01 logic" ON otherwise 0 =100%. I'm **guessing** that a bug with 4.37 in this mode may have set a 35% value on exit (my low temp %) then the immediately reopening of Speedfan, somehow "thought" 35% was 100% and proceeded to automatically set it lower, beyond a valid value that is now "stuck" in the W83L785R.

||Fan still not going, so I have unplugged the fan from the videocard and am now running it from a NZXT sentry 2 fan controller. It's going just fine now so I can run 3D apps & games no problem. Will leave it like that for now, as it's a pain unplugging the videocard to change cables. Will still use Speedfan to monitor the videocard chip temps & volts.|
