i bought a nzxt sentry 2 and noticed that it says "Sentry 2 easily installs in a 5.25" bay and is compatible with any fan that uses voltage control." so how can i know that the fan uses voltage control?
i have 3 standard fans in my fractal design define XL that follows with the cabinet and a NZXT FN 140RB 140mm Enthusiast fan Noctua NF-P14 FLX 140mm fan(placed at the door, and only fan i notice any change in noice)
More aboutvoltage control
Speed controllable fans have a 4-pin miniture connector that would normally connect to the mobo, not the larger 4-pin Molex connector or a 3-pin miniture mobo connector.
but all connectors on the nzxt sentry 2 has onlt 3pin miniture connector
Thats what he meant, the fans controllable by controllers like the sentry have a minature 3 or 4 pin plug, instead of the large molex plugs, although you can get adaptors to or from mole/mini plugs to suit your needs Moto
