What is the ASUS Fan Extension Card? Why is it an AWESOME accessory for PC builders?
It is finally here after some extended waiting the ASUS fan extension card is available. You might be wondering what this awesome piece of hardware does and that is what this post will help to fill in.

Details behind the ASUS Fan Extension Card
ASUS has long been the industry leader in motherboard fan controls & fan connectivity. This is an area often overlooked by users thinking that a fan header is a universal spec in regards to what type of functionality it offers. Many times not realizing the fan header may not offer both 3pin DC & 4 pin PWM output control or offer induvial control as opposed to shared control or does not offer calibration and profiling or ramping and response.
Overall this is where ASUS has consistently led when compared to other board vendors. That being noted, one limitation though that was difficult to surmount was the number of headers on a motherboard as well as their location. Normally a board is limited to a certain number of headers due to the topology (layout and traces) of the board and its headers as well as the corresponding components and connections on a motherboard. Additionally, the SuperIO controller also is a factor in the number of headers supported. Last but not least there are also cost considerations.
ASUS figured out a number of solutions to offering more flexibility in fan connectivity through the implementation of true PWM output in its fan headers. This has allowed any fan of the onboard headers to support PWM splitter cables which can then control multiple fans while being powered by the PSU. This is perfect for radiators which have 2 or 3 fans. PC builders who also use larger chassis also can benefit as it can be used for the multiple fan front intakes, where you want to ensure consistent control across all those fans.
While this type of functionality is great you may still have the need or want for more physical headers or do not want to use a splitter cable. For some, it may also come down to improving cable routing and minimizing or eliminating fan cable visibility.
To resolve this issue ASUS R&D developed an awesome accessory in the form of the ASUS FAN EXTENSION card. This feature was first introduced on ASUS X99 series motherboards. On its simplest level the card will offer
3 additional headers ( supporting DC or PWM output control )
3 additional temp input sources
Serving as a PWM splitter board with support for 3 fans that mirror a PWM signal from a CPU or CHA ( CHASSIS ) header
Fans connected maintain support for Fan Calibration & profiling ( where the fans min and max operating values are automatically found through a calibration process. This allows for the fans to be used most effectively as well as enable ultra-low RPM operation.
You can see of a demo of Fan Xpert fan calibration and profiling in the video linked below

The additional temp input sources are of special importance as it opens up a whole other level of cooling control. Traditionally all fans respond to the CPU temperature. For newer generation boards like X99 and Z170 they have multiple temp input options available. This allows for different headers to respond to different temperature sources.
Your CPU and CPU OPT headers will respond to the CPU temperature.
Your CHA 1 and 2 headers will respond to PCIe slot sensors allowing the front intake fans to provide more intake airflow for the GPU.
This is important as many times higher performing CPU cooling solutions keep the CPU cool enough even when gaming that the intake fans may not respond as efficiently or Effectively as you would like.
As an added value you also have improved cable routing flexibility where instead of needing to run fan cable directly to the motherboard you can run then to the card and have then hidden from view.
Overall it is an awesome accessory that adds further values in considering an ASUS motherboards that support ASUS Fan Xpert and the Fan Extension card are listed below. You can visually confirm yourself by verifying the board has a FAN EXT header generally located in the bottom center to bottom right of the motherboard.
*please check your motherboard for which level of fan control features & functionality are offered.
