new case

HP Omen Obelisk 875-0024
Microsoft Windows 10 (64-bit)

Hi, i’m looking to get a new case with fans in it, and it says the new fans are 3-pin connectors and i think mine is 4-pin, where would i have to plug them into on the motherboard since there is no 3-pin slot ?

Hello @mattyboi 


Yes, a 3-pin fan can plug directly into a 4-pin socket and vice versa. The plugs are keyed so you cannot plug the connector in the wrong way.

I believe a 3 pin fan only changes speed via voltage control and will continue to work this way, even if plugged into a 4 pin connector.
