These temps are under what conditions(ambient and how many transceivers are installed and how high is the load?)
Code:
Ambient temperature: 27C
There's no load on it yet, as I'm still trying to mode the PSU fans, which are entirely different from the write-ups I've seen. I ordered a few parts to make the pigtails, so those won't be in until Thursday. I turned most ports off, and the power consumption decreased to just over 100w.

I finally got all my fans in, and it's whisper-quiet now! My power supplies were different than the ones in the Reddit post, but after ordering some 2/3 pin Molex connectors, I wired up my fans and was able to keep the stock fan/wiring just in case I ever need to switch it back.

Here are the details for the 450w PSU:

The DELTA fan's wiring runs from the back of the PSU to the front and splits out into two Molex connectors: a two-pin and three-pin.


Here are the parts you need to buy to wire up your Noctua properly

Not exactly sure if this is a super super super cheap deal, but it's still 48x 10G RJ45 ports with 4x QSFP ports. I know they are not super quiet, but turning down the fans to 40% keeps them cool and just slightly audible .... and it's ARISTA ;) All the other ARISTA switches I bought from them were all in super condition.

I was able to catch an offer for US$ 200.00. They, specially Tom, were very helpful with the process while eBay confused everyone again ;(
Mine broke, would always automatically reboot every 3-4 days. Sent it back. Never received a refund from the seller. Had to involve eBay Germany to get the refund.

PS: Any issues with the seller have been clarified and were finally fixed.
