Its a little bit to powerfull

of course you can use it, but a 1046 or 1048 would be better. They are small enough to be put into the case and their power is enough to serve several coolers and radiators. And they make hardly any noise, while you can hear an 1250 or a 1060 quiet good.
These pumps are only necessary if you want to use a Bong instead of a Radiator because then you need higher pressure.
Also most people here in the Forum use a 1046/48, and only a few a 1250, i don't know anybody who has a 1060.
