Inno3d GTX 1080 x2 fan controller pwm transistor

[regina_xl]

I saw that the transistor fell off and now fans always on max 100%. (4pin - and pin for pwm not working) Which transistor do I need to solder for replacement
ps.(somewhere I read that D3 BCW33 and I do not have that) so is there any alternative to take off from my old comp and solder there?
