There are 3 new additions in the 80mm range, the ULN, FLX and PWM versions. There are some very distinct differences between the 3 fans, for instance, the PWM version of course has a 4-pin fan connector cable whereas the FLX and ULN feature 3-pin connectors.
The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 2200 to 1750rpm.
The ULN version provides super-slow 1400/1100rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation.
The FLX version provides 2000/1650/1200rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation.
As mentioned all the different version will come with some different adapters in their packaging, to make sure you are getting the ones you wish you can open the flap and get an illustrated list of box contents, or you can look on the back of the packaging under scope of delivery.
Again I have gone ahead and added the 50 pence piece in for reference on size and as you can see this time it fits quite nicely on the middle circle inside the fan. As mentioned all the different versions of 80mm will have different connectors, but they will all come with 4Â Vibration-Compensators and case screws.
Noctua have gone to great lengths to make sure there fans are protected from vibrations and don’t create any unwarranted noise. Not only do they include Vibration-Compensators there are covers made from the material on all the corners of the fans where they will be screwed to the case.
