![]() While the overall quality is good, there are some rough spots on these fans, I am not sure if they are just in the case of these samples or across the whole lot, the edges of the blades are not smooth, in fact they look like they were not sanded down in the factory at all. The build quality & the materials used are great while the accessory bundle is more than reasonable. The performance of the Spectre Pro PWM fans is good being comparable with higher RPM fans (up to 2400 RPM), being also silent, the fans can be heard only at their maximum speed. The noise level was measured at two RPMs and at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db. The BitFenix Spectre Pro PWM 140 fan has been tested using a 280mm CPU liquid cooler, the NZXT Kraken X61 at max. The BitFenix Spectre Pro PWM 120 fan has been tested using a 240mm CPU liquid cooler, the SilverStone TD02 at max. – CPU Cooler: SilverStone Tundra TD02 / NZXT Kraken 圆1 – Motherboard: MSI Z97 Gaming 9 ACK / MSI Z170A Gaming M7 The following system was used to test the fans: In the case of the BitFenix Spectre Pro PWM 140mm model, its frame features an extra set of mounting holes which makes the fan compatible with a 120mm mounting slot. The fans are composed out of two sections which can be taken apart, this helps to dampen the vibrations. The reinforcement is present to reduce the vibrations during use and to prevent the blades from warping.īoth the 120mm & 140mm variants are powered using a 4-Pin Molex connector with PWM function. The blades of the fans are reinforced, this is outlined by the three raised portions on both sides of each blade. In the middle there is a lable with the model of the fan and the manufacturer’s logo. The back side of the fans & frame use 13 fins to focus the airflow. Also the manufacturer’s name is engraved at the top of the fan’s frame. On the front side of the fans in the middle we find the manufacturer’s logo. Unlike the LED variants, the PWM models use a matte plastic frame with a honeycomb pattern. The two fans use 9 blades made out of white plastic just like the frame of the fans. – Two Color Versions: No two setups are alike, which is why Spectre Pro PWM comes both solid black and solid white versions. – Silent Operation and Long Life: Like the Spectre™ Silent Fan Series, the Spectre Pro PWM features the very same fluid dynamic bearing technology for minimum noise and maximum operating life. Spectre Pro PWM features reinforced fan blades that resist warping even when spinning at high speeds for maximum cooling performance. – Reinforced Fan Blades: High rotation speeds can actually warp fan blades while in motion, resulting in more turbulence and noise. In short, our Spectre Pro PWM looks different because it is different. – Dual Ring Construction: Using a dual ring construction, Spectre Pro PWM fans not only offer aggressive looks, but also vibration dampening properties, helping to keep noise levels in check. Performance freaks are going to love Spectre Pro PWM. – High Pressure/CFM Design: Engineered for maximum pressure and airflow, Spectre Pro PWM delivers a torrent of air that will keep your CPU cool even when the action heats up. This technology enables your system to control your cooling with much greater precision than conventional linear voltage fans, making them perfect for CPU coolers. – PWM Technology: Spectre Pro PWM users pulse width modulation technology to adjust fan speeds. The product comes with the following accessories:īearing Type: Fluid Dynamic Bearings (FDB) On the right, there are printed the manufacturer’s logo and the name of the product. The back side of the box presents the feature of the products, below we find a table with the specifications of the product. On the sides of the packaging there are printed both the manufacturer’s logo and the name of the product. ![]() The name of the manufacturer and the model are placed on the upper part, below we find the name of the fan. The Spectre Pro PWM fans come in a black box with a plastic window on the front side. The company is specialized in manufacturing computer cases, power supplies, fans and different IT accessories, the latest launched products are aimed at the modding segment. is an IT manufacturer founded in 2010 by a group of enthusiasts specialized in producing cases, Power Supplies, fans and different IT accessories.
