The brushless SPAL fans are so friggin expensive, it's even painful to shop them. And the SPAL brushed fans are about the cost of other brushless offerings.
Some of that though is due to the electronics, many brushless fans have a 'simple' PWM controller built in. All you need is a programmable PWM output to run them.
Being able to run a pair of 14" fans is certainly an advantage over a pair of 12", and the cost difference between is nominal.
Nice thing about that Flex-A-Lite fan is that it can run either off a voltage signal or a PWM signal. OE replacement type and many other brushless fans require a PWM input, as a reminder.
Overkill with a cooling system is a win-win, it's like that saying about condoms...
