GPU AIO mounting and fans/power

Invertigo · 16 Jun 2020 at 23:58

So, I happen to have an AIO unused so been looking at getting the NZXT G12 kit to use it on the GPU. The only question I really have, how best to connect up the pump and fans to which appropriate sockets - it's an ITX system so the motherboard has one CPU fan header, one PWM/Pump header and one 3 pin (Technically 4 pin, but only has DC control and no PWM).

I'm also aware you can connect fans to the GPU header with an appropriate adaptor, considering this might be the option for the rad fans?

I connected my rad fans to the GPU mobo using an adaptor. That way you can control the speed via the driver software or afterburner. pump can be connected to any header really.

Thinking I could run both pumps off my PWM/Pump header, but would it be better to use a SATA powered splitter in this instance? I know running a couple of fans off one header is fine but dual pumps is a new thing to me.

depends what current the header can handle.

Can you connect the pump and fan from the G12 to the GPU header using the adaptor and a splitter? Makes more sense to have pump speed directed by GPU temp rather than CPU or Mobo temps which would be the case if connected to any of the motherboard headers.

Just use motherboard headers set pump to max and fans as fast as possible before noise bothers you no point having them ramp up and down

Can't see the point having the pump running at full speed all the time. Was planning to have it at half speed when temp low and full speed when temp goes over 50

These are gpu temps not mb or cpu

Yes I know u meant gpu I’ve had the g12 on 1080ti 2080ti and found this was best. AIO don’t have the greatest of flow speeds hence full pump gave the best cooling

It's a very quiet system and the hum of the pump at full speed is easily audible. Full speed will give you the best cooling but if I had to choose between 40 without any noise and 60 degrees with noise when working on a spreadsheet I would go with the first option.
