Network Cabinet Fan (2pc Kit) Pair of 120mm 4in Fans 110V AC -Tupavco TP1511

The included self-tapping screws don't fit. They are two small and simply push through the fan holes. Not a problem for me as I just re-used the nut and bolt from the old installation. These fans are very quite. I question there rating of 95 CFM as the feeling of air flow when placing your hand over the exhaust is very low. I'm still satisfied as both fans are exhausting the hot air in my cabinet which is the goal. I like that both fans come connected to the AC power cord and includes a Cable Tie Mount already secured. If you don't use the cable tie mount, just cut the cable tie.

I did not care if these fans were going to be loud in my cabinet, but after installing, I cannot hear these fans at all. The rubber shock absorber things were easy and worked. The top of my cabinet is a little awkward to get to so not having to blindly use a screw driver was a plus. The fan that came with my cabinet did not work. As a comparison to that fan, these have much heavier wiring and more importantly... They work. Lots of air coming out of my cabinet, I cannot measure it, but it is lots.

The screws that were included were crap, and not self tapping. 3/4" #10 screws from my local hardware store worked great, and no issues with the fans, they aren't too loud and pulled air out of the cabinet.

Very low noise level, easy to install.

These fans may be appropriate for a server room separated from the people trying to work but you cannot use it in the same room as you sit. They are really loud and have no speed control or even an on/off mechanism. You just plug them in and they turn on. That's it for control. I had a single fan of the same size which sat directly on top of the primary heat generating component before. I could barely hear it on high and not at all on medium or low. I only replaced it because I thought dual attached fans mounted at the top of the cabinet would be more professional in the long term. They don't seem to produce greater airflow per fan than my original fan did. No idea why they make so much noise. They do the job if you don't care about noise... disappointed though because I do.

Didn’t need this for cooling so no comment there. Needed something that draws 30watts for vacuum auto switch actuation (dust collection system). This setup allows me to connect a rocker switch to these fans, to allow for use of the vacuum without having to power on the table saw or router (which is what the vac auto switch does). Fans did the trick! Solid construction.

I brought the other fans from this company without reading a review and those sound like being in a data center, it was like I was close to a small jet engine but these fans are quiet with a very nice wind speed. These are good for small to midsize cabinet.

A picture shows screws are stripping (unable to firmly secure either fan). The rack screw holes are not an issue (screws go through them fine). That is if holding the fan in one's hand and attempting to install a screw, only after 1/4 - 1/2 turn, the screw stops turning. Quality control required with screws.

Encajaron perfectamente en el gabinete, extraen el calor del mismo y el cable es suficientemente largo para conectarlo al enchufe de la corriente.
