Which 140mm fan to get and looking for cheap ones too..

[TheExcaliber]

Well atm still looking for 2 140mm Fans but came across these two:

1) https://www.amazon.com/dp/B00F6S0XK8/?tag=pcpapi-20

OR
2) https://www.amazon.com/dp/B007TSREFU/?tag=pcpapi-20

Opinions on these two??
Planning to get 2 140mm fans so I guess price also counts.. :l

Errr, not really. Both types of control rely on the motherboard/fan controller changing the output to the fan.

 

There are 2 ways to control fan speed. DC and PWM. 

DC control forces the fan to spin more slowly by lowering the voltage supplied to it. This puts most of the work of fan speed control on the motherboard.

 

PWM control tells the fan what speed to spin at. This means most of the work is on the fan side, and it is a better overall system in my opinion, as slowing the fan from within the fan motor allows more complete control, so gets better results than just lowering the supply voltage.

 

More PWM fans can be controlled off one fan header, as PWM is a digital signal, so the fans draw no power from the PWM pin on the motherboard. The power to the fans can be provided directly from the PSU. This reduces load on the MB fan header, but in order to do this, a special fan splitter is required, with an auxiliary power connector.

 

DC fans on the other hand draw all their power from the motherboard, so the max number that can be connected to one header is 2 to 3.
