Connecting MQT and TKG 2510s to motherboard

[conoftheangels]

Hey all, I’m in the middle of building my first PC, and while plugging in I’ve found two cables which I’m not sure where to plug in. They’re both 3-pin with a locking mechanism, but I can’t seem to find where they go.

My motherboard is an ASRock z170 Extreme7+, and my case is a Phanteks Enthoo Evolv Pro M.

Please help me out, thanks!

Nevermind, turns out I’m dense: I didn’t know you could plug a 3 pin into a 4 pin slot.
