The pins are for Ground, Voltage, RPM sensor, and PWM.

Typically it's like this, 

 

Red - Positive

Black - Negative

Yellow - RPM sense

Hello,
I bought a faulty Lenovo ThinkPad T450.
I would like to fix it to a desktop pc.
No heatsink and no fan on the motherboard.
When I start it it shows "fan error" and turn it off itself.
I have a Chromebook HP 14-q011sa heatsink and fan.
Problem is the fan plug on the motherboard have 5 pins.
My fan have 4 pins.
It spinning, but still "fan error".
I need something more to realize it is there.
Semantic, and how I pug the fan :images are attached.

Could you help me please how can I use this fan?

Please start a new thread instead of hijacking and necro-posting. 

I've been using computers since around 1978, started learning programming in 1980 on Apple IIs, started learning about hardware in 1990, ran a BBS from 1990-95, built my first Windows PC around 2000, taught myself malware removal starting in 2005 (also learned on Bleeping Computer), learned web dev starting in 2017, and I think I can fill a thimble with all that knowledge. 😉 I'm not an expert, which is why I keep investigating the answers that others give to try and improve my knowledge, so feel free to double-check the advice I give.

My phone's auto-correct is named Otto Rong.🤪😂
