OLD NTB 486 .. 3pin things : AU34 and CR26

[PC-maniak]

Hi, I have an old 486 laptop whose fan doesn't work and the part that controls the fan contains 3 pin components AU34 and CR26 as in the photos .. will anyone help me find out what it is? I searched everywhere.. but it doesn't make sense .. they are old parts

CR and AU are probably BJTs or MOSFETs.
