The new innovation from Enermax is called "Adjustable Peak Speed" (APS) and enables the adapting of the fan to its field of application. Therefore, the manufacturer can address three different target groups with just one product: At default setting ("Silent Mode"), the fan runs with max. 1,300 to 1,500 RPM, depending on the model.
For the installation in a silent PC system, the user can slow the speed down to max. 1,000 or 1,200 RPM ("Ultra Silent Mode") and make sure that the fan will work virtually silent. At "Performance Mode" the noise generation does not play a major role. The new APS fans will run with up to 1,800 RPM and reach the best possible cooling performance with max. 147.29 m3/h.
Within the selected mode of operation and RPM range, the fans are controlled by pulse width modulation (PWM) like the Cluster Advance fan or by a thermal sensor (Everest Advance). The Magma Advance and the 180mm models T.B.Vegas Quad and T.B.Apollish are not equipped with an automatic RPM regulation. Nevertheless, they also come with a small switch at the back which enables the so-called "Shift Speed Control". It will change the fixed maximum speed of these fans in three steps so that end users can select the most suitable cooling mode for their system. As usual, the 120mm fans from Enermax are based on the trusted Twister bearing. The patented technology ensures a smooth and durable operation of up to 100,000 hours MTBF. The Twister bearing further contains a solution for one continuous problem of end users. After a longer period of time, the fan blades are covered with dust which will finally also influence the system cooling. Therefore, end users can detach the rotors of the Twister models and clean them from dust more comfortably.
Apart from the standard mounting holes for 12cm and 14cm fans, many cases on the market, including the Enermax towers Fulmo GT, Fulmo, Fulmo ST and Ostrog GT, are equipped with slots for big-size 180 and 200mm fans. Latter offer a much better balance between performance, speed and noise generation than smaller fans. At the same speed, a 180mm or 200mm can pull much more air: Already at 600 RPM, the new Enermax T.B.Apollish 18cm and T.B.Vegas Quad 18cm achieve an air flow rate of 116.55 m3/h.
For comparison, to reach a similar cooling performance, the Enermax Cluster 12cm (UCCL12) requires a speed of more than 1,200 RPM! It is hardly surprising that the demand for big-size fans is growing steadily. At the same time, case vendors still apply different assembling standards for these fans. Enermax has therefore integrated two mounting holes in the fan frame – one for 180mm, one for 200mm fan slots. Therefore, T.B.Apollish and T.B.Vegas Quad can support both two prevalent mounting systems.
