Color me impressed by how much variation Bitspower has managed to put into the five products we have detailed recently, especially so with the fans that have similar spec sheets but are so different once you get them in hand. The value-oriented Touchaqua NJORD had to hit a certain price point, and yet offers quite a lot for the money considering you get a bundled fan hub, an LED hub and controller unit, and the associated dRGB lighting compatible with motherboards. The Bitspower Njord Dual Fin builds upon that base with those features intact, and we get more with the fancy daisy-chained cables, concentric lighting rings with two different color options to choose from, and a different rotor design where the name comes from.
The Bitspower Njord Dual Fin triple pack at $85 is a good buy considering everything. The included hubs and controllers would easily be $15 together, with the LED multifunction controller alone retailing for $12, so the fans themselves come in at ~$20 each. RGB fans that do pretty well as radiator fans while offering a large range of RPM control and motherboard LED control are definitely worth checking into, especially given the neater cable management here when using multiple fans together on a radiator, and the lighting effects are nice, too. As it stands, this is among the better of the RGB fans overall, with the CORSAIR ML and EK-Vardar EVO being the other contenders for those wanting a nice balance of performance, noise, and aesthetics without it costing a lot, especially with the triple pack. Just don't buy these individually, as you basically get the third fan for nothing and the accessories on top with the triple pack.
