In June last year, Thermaltake announced the launch of the ToughFan 12 14 Pro fan, whose fan blades are not only specially designed, but also made of strong and stable LCP material, making the overall structure more compact and efficient, and can provide stronger airflow and static pressure to enhance the overall air intake efficiency. Recently, Thermaltake has added the magnetic splicing of SWAFAN EX and the replaceable fan blade design on the basis of the SteelShadow Toughfan 12 14 Pro fan to create the **SteelShadow ToughFan EX12 14 Pro fan, which further improves the design aesthetics and installation flexibility of the product. 
The ToughFan EX12 14 Pro features the new MagForce 20 magnetic splicing design, and the contact area of the Pogo Pin magnetic contact is tripled, whether it is splicing fans or magnetic cables, it can be more convenient and firm, and get rid of the shackles of cumbersome wires. Three magnetic cables are provided in the triple pack. At the same time, the fan also adopts a replaceable fan blade design, which allows players to install positive or reverse blades according to their own installation needs, which can not only better release the fan performance, but also ensure an excellent frontal appearance. In addition, the replaceable fan blade design also allows the fan blade to be easily removed and rinsed with water, which is also very convenient for ash cleaning and maintenance.
The ToughFan EX12 14 Pro is equipped with the same nine widened fan blades as the ToughFan 12 14 Pro, with a maximum speed of 10% at 2000 rpm and a maximum airflow of 708/119.6 cfm with a maximum wind pressure of 319/3.57 mmH2O, corresponding to a noise value of 226/31.6 db db(a)。After the replacement of the reverse blade, the indicators were reduced, and the maximum air volume was 6421/102.3 cfm with a maximum wind pressure of 260/2.95 mmH2O, corresponding to a noise value of 298/34.1 db db(a)。
The new square fan frame design allows the ToughFan EX12 14 Pro to have an extremely narrow gap, and the beveled edges at the rear minimize air leakage, making it a better fit for the chassis or radiator. The fan blades are made of a robust and stable liquid crystal polymer (LCP) that reduces vibration when rotating at full speed and keeps noise extremely low. In addition, the four corners of the fan are equipped with shock-proof rubber pads, which are made of soft rubber material that is not easy to peel off, which has excellent shock-absorbing effect, so that the inside of the case runs smoothly and reduces the noise caused by the resonance between the fan and the case.
