What is an M.2 fan header?
An M.2 fan header is a type of connector found on some motherboards that allows users to connect a fan to the M.2 slot. This feature is designed to provide additional cooling for M.2 SSDs, which can run hot during intense usage. The fan header is usually located near the M.2 slot and is labeled as “M.2 FAN” or “FAN M.2”.
Not all motherboards have an M.2 fan header, so it’s essential to check your motherboard manual or specifications before purchasing an M.2 fan. Additionally, not all M.2 SSDs require a fan, so it’s crucial to check the SSD’s specifications as well.
Can I use any fan with the M.2 fan header?
Not all fans are compatible with the M.2 fan header. The fan header on your motherboard usually has a specific pinout and voltage rating, so you’ll need to ensure that the fan you choose matches those specifications.
