NEW Thermochill PA140.3

[SNiiPE_DoGG]

140.3 is better than 4 x 120 ---> more surface area on the 140.3 and the fan blade area to motor hub area ratio on 140mm fans is greater by a large amount .
120.3 = 43,200 mm^2
120.4 = 57,600 mm^2
140.3 = 58,800 mm^2

120mm fans is 6.09:1 fan blade area to motor hub area ratio
140mm fans is 8.64:1 fan blade area to motor hub area ratio

then by calculation of fan blade area ((Pi*fanradius^2)-(pi*hubradius^2))*#fans) we can say utilized area.

120.3 = 29,127 mm^2
120.4 = 38,837 mm^2
140.3 = 41,373 mm^2


therefore PA140.3 is ~6% better than PA120.4 @ equal fan speed and design on each (120mm yate loon and 140mm yate loon for instance)
