Sapphire Radeon TOXIC R9 270X problem with fans

[ostryo]

Hello everyone. I have a strange problem for this card. Generally is fully operational, it gives a picture and can be used normally. The problem is that from the moment the computer is turned on, the fans are still working at 100% and it cannot be changed. Card temperature checked in gpu-z is very low. I checked on two BIOS which card has and the effect is the same.


Does anyone have any tips or encountered such a problem?

Thanks

I managed to solve the problem, maybe someone will need it. Defective shorted bipolar transistor (base-collector) marked as Q214. It is MMBT3904LT1G (SMD 1AM marking). It is located right next to the fan plugs. The fans started to run normally.
