14 DAY TRIAL // German developer of advanced cooling solutions Blacknoise has finally presented the result of its so-called 'collaboration' with the members of the HardwareLuxx forum, who focused on discussing the product's detailed characteristics, such as the autorestart function, controllability, cable length or optics. The company used the recent weeks to collect suggestions from the forum's members, a feedback that it then used to put together a gentle but strong, all-black casing fan. The product goes by the name of Noiseblocker BlackSilentPro and comes in five distinct models, distinguished through their size, rotary speed, airflow and minor estimated time before failure.
The series features two 120mm and three 140mm fans, all boasting a low-noise NB-NanoSLI bearing. All come with two sets of cables (20cm and 50cm) and an anti-vibration frame made of rubber. The 120mm fans are the NB-BlackSilentPro PL-1 (11 dBA (noise), an airflow of 68 m3/h, and an MTBF of 180,000 hours) and the NB-BlackSilentPro PL-2 (1,400 RPM, 20 dBA, 96 m3/h and a 160,000-hour MTBF).
The series includes three 140 mm fans. The NB-BlackSilentPro PK-1 spins at 700 RPM, produces 9 dBA, has an airflow of 49 m3/h and is guaranteed to run at least 180,000 hours before failing. The PK-2 will run for at least 140,000 hours at 1,200 RPMe, boasting an airflow of 93 m3/h, while producing no more noise than 20 dBA.
Lastly, the most powerful of the series is the NB-BlackSilentPro PK-3 140 mm case fan. This one will produce no more than 27 dBA of noise while spinning at an impressive 1,700 RPM, providing a sustained airflow of 153 m3.h. Unfortunately, this fan has the lowest MTBF of the lot, with only 120,000 hours estimated before a possible failure.
The fans are already available for purchase in stores and come with a six-year warranty. All devices run on a dielectric strength of 5 mA at the most.
