Great POE Hat for rackmount Pi
This is a really low profile POE Hat or the RPi 4B. It is very quiet and fans spins up/down based on load. Entirely appropriate for a Pi that is in a rack mount orientation.

Fan died after 90 days
Fan no longer functions after 90 days of continuous use. Bummmer...

Nice hat, fan sucks
Fan died after a solid year and a half of uptime, and yes it did make some horrible sounds for a while.

Works as advertised
I had a question and the reply was quick. I installed on 2 RPI 3b+s and have had no problem with them so far.

Rock solid power. Rock hard migranes.
These things are great at providing plenty of very stable power. On the other hand, it is like having a constant loud dog whistle going 24x7. It piggybacks off of the driver for the official POE hat (so there is no configuration needed) but the fan is not the same. Unless the Pi is slammed and trying to overheat, it sounds like a super loud dog whistle. If it is overheating, the fan works fine, making loud but ordinary fan noises.Adjusting the thresholds works to move the whistle around, but there is no way to disable the broken speeds entirely so it will always make that noise at least some of the time. If you are running more than one, you'll find that they are resonant but not quite in sync. Makes it surprisingly much worse than you would expect.

Doesn’t fit
Doesn’t seem to fit a pi 4 with heat sinks

Same as Most…
POE Hat great fans are weak. Would love to replace. Can someone from the company help with how do I buy a replacement fan size and the connection size and type. Would be 5 if fan would last. Moved to Raspberry Pi version of POE

Bad connection on PoE HAT 4-pin connector
I have 02 of there PoE HAT modules on a UCTRONICS 1U rack kit and both present the same problem: bad connection at the 4-pin PoE HAT connector. RPi module will not power up unless we press firmly the PoE HAT module at the PoE 4-pin connector. This is VERY ANNOYING and prevents power failure recovery, as someone will need to physically go onsite to press the PoE HAT modules again.

Noisy
Fitting this was fairly trouble free, and I paired it with the Uctronics 1RU rack mount for the Pi. Unfortunately after about 3 weeks the fan started to get really noisy. I have it running in an open rack in my walkin robe, and the noise if great enough to now need to close the door to sleep at night. I will be swapping for a Pi original POE hat, and maybe try replacing the fan and try it again on my next Pi project. Shame.
