Got my OcUK H²Flo Liquid CPU Cooler and was wondering why is it so loud? is it meant to be like that?

the most likely cause is that you bought a really loud fan. however, it might be caused by you plugging the pump into the wrong socket, as this needs 100% power at all times. or, you might have some air flowing through the pump

Cos the OcUK H²Flo Liquid CPU Cooler didn't come with instructions can you tell me what plug into what socket please.

Pump plugs into CPU header and make sure it is set to full speed in BIOS.

Plug your fan into whatever.

How do you do this? I just plugged it into the CPU header, it reports that it's spinning at like 4000rpm though.

I've just worked it out, after fiddling around with it. I plugged the pump into the PWR Fan socket. If you want to keep it simple you are going to need a PWM Fan for the radiators so it can automatically detect when it needs to raise or lower fan speed which plugs into the CPU fan pin.

Enter your BIOS.

Find any fan control settings.

Make sure all speed control for the CPU header is off.
