L3+ Fan Problems

[Reudiga]

Hi,

my L3+ was delivered but i had problems. Its started normal, short time than showing

Dec 27 13:46:14 (none) local0.err cgminer[374]: Fan Err! Disable PIC! Fan2 speed is too low 0 pwm 100
Dec 27 13:46:15 (none) local0.err cgminer[374]: Net Err! lastest job more than 2 mins! waiting ...
Dec 27 13:46:16 (none) local0.err cgminer[374]: Net Err! lastest job more than 2 mins! waiting ...
Dec 27 13:46:17 (none) local0.err cgminer[374]: Net Err! lastest job more than 2 mins! waiting ...

But why?! The Fan2 is connected and working when starting... after this error stops to 0.

I already tried to update Firmware, but was newest


// I switched the Connections from Fan1 and Fan2 and the Miner shows also 0 on Fan2

Yeah, that was what i think...

Think the Firmware or Controller Board make some problems...

But crazy is, directly after start all two fans spinning fast... so think its firmware

Hi,
Did you figure it out? Was it a bad board? I don't have the miner with me so I can't do much hardware inspection. Which firmware version do you run?

Thanks

look after the airgrid is the distance to the fan ok
