Hi,
I built my computer quite a few years ago and since I've forgotten how to replace fans and some other technical things.
I wanted to replace the noisy fan I have on my Thermaltake chaser MKI, (the mobo is Asus sabertooth Z67), but there are many components connected via a single multi pin connection to the motherboard, and the fan is included.

Can I just cut the three wires leading to my fan and I'll be fine? And I don't seem to find a 3 pin connector like my fan has on the mobo. Will I be fine connecting it to a 4 pin connector, leaving one pin out?
Any reply will be greatly appreciated as I just took the computer outside especially to clean it in install the fan, and now this uncertainty comes along..
And it's pretty sunny, I don't wanna hurt it to much..!


Many thanks!

The fan pin connector and the fan header are keyed, they'll only connect 1 way easily. If you need to use force, it's not the right way.

Don't think I've ever seen a fan that's permanently attached to anything else other than itself. I'd make damned sure to trace that fan all the way from the fan to the connector, it's highly probable that there's a switch/hub in the way, so just chopping at random wires can do more harm than good. Cases, especially wiring is most always modular, it's the only way you can get wires where you need them to be, a large fan kinda makes that impossible if it's permanently attached, a simple 3 pin connector on a switch or hub solves a lot of issues.

Thank you!
So I will cut the wires.

I just found a 4 pin connector called cha fan 3. Should I connect the new 3 pin fan to there? And will it matter which pin I leave out (shoud it be the right or the left one)?

Thanks again!
