Tupavco Rack Mount Fan - 4 Fans Server Cooling System - 1U 19" Rackmount Cabinet Panel w/Adjustable Temperature Control (Heat Monitor - Digital Display) Alarm Sensor (Overheat Air Flow Exhaust) TP1701

This product offers a programmable temperature control, which is nice, but it can only read in Fahrenheit which makes it unsuitabe for Canadian customers. When the manufacturer was contacted they said that this product was only made for distribution in the US and they don't know how it got onto amazon.ca. The unit needs to be used with a rail due to it's weight, but unlike most other rack mount devices, no allowances were made in it's height for that. The side flanges are welded on, so when they don't line up with the rails, there is nothing you can do. I put the rails in upside down under the unit to offer support.

Extremely easy to install. A little loud (my server is kept in a closet, and I can hear it starting up with the door closed). Only complaint is the manual (2 pages)

Funciona muy bien, enciende cuando detecta calor ya que trae un sensor que lo puedes ubicar donde sabes que se genera mucho el calor y prenderá más pronto.

El producto llego dañado y es muy ruisoso

Seller gets perfect 5 stars. The item is exactly as shown and does what it was made to do. PROS: Solid metal construction and has some weight to it. Four temperature controlled cooling fans that move a lot of air. CONS: cheap control display panel. Vague instructions. Questionable quality control. For what you pay for this item and what it is (value for the money) this is a very decent product. Solid all metal construction with 4 fans that move a lot of air. The temperature sensor is super sensitive and the display is very visible. Comparable products cost a little more without the temperature control feature requiring you to manually turn it on and off. My item did not work out of the box. I emailed the seller who responded the same day and was sending a replacement next business day. No questions asked, haggle free process. These things happen I just wanted a working replacement but Rebecca went beyond and even compensated me for my time. A+ customer service and now I have a pretty decent rack fan. The seller stands behind their product and the sale. Thanks to Amazon and sellers like these.
