What is the best diameter to go with? and is it bad to start mixing diameters in a single loop?
The EVGA GTX 580 is available with a water cooler factor direct but the fitting options are 1/4" and 1/2" and most rads I've seen are 1/4" but most pumps seems to be 3/8" and I feel Like 1/4" tubing won't provide enough flow
