Review on Amcrest 5Series 4K NVR 16-Channel NV5216: Record and View/Playback 4K @30fps with 16CH Capacity, Supports 2 x 10TB Hard Drives (Not Included) by Teo Alston

16ch DVR arrived on time, well packaged and no damage. I bought an AMCREST DVR to get rid of the constant "Login timed out" message that Amcrest had. The main thing is that the cameras connect quickly. However, the CPU temperature is quite high, at least I think so. I removed the cover, also to install hard drives, and noticed that the fan was a bit anemic. There are cutouts for two fans on the side of the case. Not sure how this will affect the warranty, but I replaced one fan with a Noctua fan (Noctua NF-A4x20 PWM, premium quiet fan, 4-pin (40x20mm, brown)) and a second Noctua -Fan on the other side added Fan. Chassis. Two fans lowered the CPU temperature by 20 degrees Celsius. The drives also stayed colder. Since this device operates 24/7, the additional cooling should increase the lifespan of the electronics.
