I have to replace my 120mm AIO cooler, but don’t understand how the wiring works. Custom pc from CyberPower PC.

Those coolers are just working by 4 pin molex power right now, which you see in the back stacked upon each other(Always 100% fan speed).
The one you have in your Hand you can put on your Board, then you can adjust fan Speed/Curve in Bios. You can remove the Molex Switch that is connected to it when Put on Fan Connector on Board.
Ok so you’re saying I can just disconnect those larger (molex) connectors completely? And connect the fan directly to the board?
And that info about 100% fan now makes a whole lot of sense because I used to wonder why the fans were always running. Probably why it died so fast.
Yes, they Just get full Power from the Molex. You usually have some Sysfan 4pin Header on the Board where you can connect those small connectors.
You can just remove that Molex stack and fill the Slots on the Board. If there arent enough you can sti use the Molex for that ones.
Thanks! If you don’t mind, I’ll probably have a question or two once I get the parts and try to install it myself. Appreciate the help.
No problem feel free to ask. You can dm me
Got the parts in last night and managed to get it working! The AIO cooler (H80i v2) ended up being a lot bigger than the original one, so had to skip out on the 2nd fan. No way that was going to fit. Got all the fans on the motherboard now, which is much better. Thanks for that tip! Appreciate the help.
What Case are you using, AIO's can be often placed in the front or elsewhere to. The Fan you couldnt use of it you could also integrate on another slot in the pc. If you are running out on fan slots, you can get chip y-splitter fan cables on the internet.
Quick question though. Which way should the fans be installed? Should the air be sucked out of the system or should it be blowing cool air in? Or is it a combination depending on where the fan is located?
In the front and floor air needs to be sucked in, on the top and back it needs to be pushed out. There you go with perfect Airflow.
Ahhh ok! I think I got it all right hopefully. Played some games and the temp stayed around 40 to 50 celsius! And now the fans ramp up and down depending on the cpu temp rather than full blast all the time.
I used the extra fan on the top of the case. So air is coming in from the front and exiting from top and back. Though I only have one fan on the back now, which is hopefully good enough.
