2 pin PC fans are normally using just Ground and +12V for power4 pins adds tachometer output and PWM input.you can simply use available 2 pins in a regular 4-pin jack after modifying your connector a bit (just make sure you connect right pinout) and ignore the rest.Or as someone has suggested below - get +12V from SATA power via relevant adapter.
Hi, I have a question regarding Dell Precision T5810. I need to install a Tesla T4 in the mentioned workstation, and I bought a DC brushless fan for cooling the GPU. However, it has a 2-pin female header and certainly will not fit in the 4-pin male slot of the motherboard. Any solution I may try? Thank you for reading
