Hi, so I just recently upgraded from my FX8350 and gone to an R5 1600X. I got a Cooler Master 120 AIO water cooler and I have a problem. Unfortunately, I saved on the motherboard and it only has two fan headers, one which only the exhaust fan at the back of the case can reach and the cpu one that only the part of the AIO that touches the cpu can reach. So this leave me with an unconnected radiator fan. My question is: can I connect it to a molex through an adapter? Or does it have to go to the cpu fan header?
 
Solution
Oh i see the issue. Yes, like the previous poster says, I'd connect the pump instead of the fan to the PSU. Running your fans at max speed all the time (and for those CM fans, max speed is considerable, 2000RPM) will sound extremely loud and annoying if at that speed all the time. I have the SP edition of the same fans and even at 1600 I can hear them very clearly even though headphones on. This is not an option you want to do. Unless, as previous poster already said, you get a voltage limiting cable. Some of these fans have also max RPM limiting built on the fans themselves as a switch (I have this on mine), so check that you can't quiet them that way instead. What motherboard model is this?
I'd also talk to CM about this. They may...

But if it's the other way around, will it be a problem? Because you see, I only saved on the motherboard, the case is quite big and I mounted the radiator at the front of the case, in this case the fan header will not reach the cpu thing to connect. So I will have to buy a fan extensor and a molex adaptor, and if I do my way, it's only a molex adaptor.

Ok which AIO is this? Because fan should plug into the radiator or the pump, and then you should have a separate cable that comes with an aio to connect that to the motherboard. If you didn't get it, you should ask the company that makes the aio to send you one.

It's a cooler master liquid master 120, I didn't see a header on the radiator and there is a cable coming from the pump, which I plugged into the cpu header. I don't mind the fan at full speed, I'm always wearing headphones anyway.

I'd also talk to CM about this. They may have a solution or an alternate cooler that uses only one fan header to offer you.

I can't connect the fan anymore, I will stick to the noise. Thanks though.

It's a GA-A320M-DS2
