Question

Do 120mm case fans cool your computer better then 80mm fans?

Answer 1

A 120 or an 80 mm fan may have the same ability to move air at the same rate but at different  fan speeds.

A 120 mm that spins a little slower than an 80mm  might be quieter.

At the same speed a 120 will move more air.

Answer 2

welll depends wats the rpm on the my 80 mm fans spins over 250 a min and my sis 120 mm spins at 200 mm soo depends on the rpm of the fan

Answer 3

Most often yes but it also depends on the pitch,# of blades and rpm of the fan.High doller 80mm fans tend to out perform low cost 120mm fans.

Answer 4

Both 120mm and 80mm fans have the same potential.

But the good thing about bigger fans is that it is able to move more air with less rotations. So a 120mm fan can move the same amount of air a 80mm fan does with less rotations. And with less rotations come less noise.

If both a 120mm and 80mm fan were rotating at the same rate, the 120mm fan would move more air.
