My $0.02
Dear manufacturers:
Water cooling isnt supposed to be pretty and petite; it is supposed to perform well and be quiet. As such, I remain unimpressed by the great aesthetic details when you use small tubing, smaller radiators, and restrictive elbows and fittings.
For more information on properly watercooling your computer, please see
www.dtekcustoms.com and
www.dangerden.com. Note the size and surfacial area of the heatercore they sell compared to your small ones. Note the lack of 90 degree fittings and quick disconnects on these kits. Please study; there will be a quiz later.
Sincerely
pH (likes the look of a big hunk of homemade copper on CPUs actually)
