So, I've got a SONY VaioBook from 2012, my laptop fan is pretty much broken and doesn't work, I've replaced the thermal paste so I can atleast use this without instantly overheating. I've got a spare fan from a laptop but I want to fit that fan to this one and this has a 3 pin connector and the fan I want to connect is a 4 pin one! Please help cuz I don't want to spend any money cuz you know I am a teenager and I don't have any money to spend ;(
