Quiet fan with great air flow!

Quiet fan with great air flow!
The flat screen monitor gets hot from its own reflected heat from inside the "cubbie" of the computer cabinet, so I added this fan to cool the monitor. The fan works great.The fan is mounted at the back of the cubbie in the floor, which also cools the UPS and the VoIP module (Magicjack Plus). The fan is mounted with Bgears 120mm filter grill, Bgears wire grill finger guard and a Ultra vibration dampener.The fan is powered by a 12VDC CCTV AC power adapter with a 2.1 x 5.5 male power jack. To power this fan you will need a 12VDC 0.5 Amp (or 500 ma) minimum. This fan is energy efficient. It uses only 4.2 to 4.5 watts, which means that running 24/7 this fan will take 9 to 10 days to use 1 kilowatt of electricity. In addition, running 24/7/365 the fan would last about 6 years (50,000 hours).Had to modify the included power cable meant for a computer tower/cabinet. I used a soldered 2.1 x 5.5 female power jack with screw over housing because prefer soldered connectors, but you can use a CCTV 2.1 x 5.5 female power jack adapter (which are relatively afforded in multipacks here on Amazon) with screw terminals. (There are some posted photos.)As with any "muffin" box style fans, using a filter will reduce airflow slightly. A rule of thumb is 10% to 15% depending on the filter, the cutout the fan is mounted to, etc.This fan's 69.69 CFM with the filter on the intake side results is an airflow around 60 CFM give or take in this application, which is still 1 CFS (cubic foot per second). More than enough in many applications.I used the included screws to mount the wire grill (finger guard and wires too) to the fan exhaust side. I lost one set of screws (bought 2 fans) and found that replacements can be purchased. A four pack of screws PacTech PA-SCREW02, you can find these on line or computer components supply store.To get the best airflow (CFM) the fan cutout is very complicated. Many times just a round hole is cut in the cabinet or chassis. 120mm is 4.72 inches, so the hole size should be around 4-1/2" to leave enough material for the fan to "seal" to cabinet/chassis.The vibration dampeners do not affect the airflow in any way but help reduce the noise transferred to the chassis or cabinet. The 19 dB rating makes this fan very quiet in its own right and with the vibration dampening; you can barely hear the fan running!I found that if you do not install the wire finger guard, the plastic housing "howls" or "hums" slightly in the second application I did. After I installed the wire guard, it stiffened the housing and the "howl" or "humming" went away.Depending on the wood in your cabinet, you may have to seal the cut suface. The particle board used in one cabinet had very fine saw dust and the fan's suction was pulling some of the saw dust from the cut edge of the hole. I used a craft wood sealer we had, but Kiltz is even better if you have some left from another project. With a foam brush applied 3 coats of wood sealer, allowing 45 minutes between coats to dry. The particle board "soaks up" the sealer, so take your time and get a good even coat each time...then reinstall the fan!

Reviewed in Mexico on August 11, 2020
Excelente producto, por su precio es de las mejores opciones que se tiene a la hora de elegir entre la gran variedad de ventiladores para gabinetes, en total he comprado 5 de estos y puedo decir que si son algo ruidosos pero no es exagerado el ruido que emiten, en cuanto a su función, el flujo de aire es bastante bueno, antes de comprar estos 5 ventiladores solo tenía 3 de la marca Eagle Warrior y la temperatura de mi GPU llegaba a los 80°C y después de instalarle los cinco fanes mantengo temperaturas de 65° - 69°C.
En general son buenos y los recomiendo mucho si su presupuesto es algo limitado.
