I'm on the hunt for an NVME enclosure that specifically supports Thunderbolt 4 (not just USB-C) and has passive cooling. I'm okay with spending a bit over €100 or $100, but I can't handle fans. The previous UGREEN model I tried had fans, and my current ACASIS keeps idling at around 50 degrees Celsius, which I'd much rather see drop to about 40 degrees. Also, I found an OWC option on Amazon but it doesn't seem to be genuinely Thunderbolt, which I believe is necessary for SMART and Trim functionalities.

Both the 1M2 versions, whether it's 40G or 80G, actually support both SMART and TRIM features, so either should meet your needs.
If you're struggling with cooling, I modified my ACASIS with an older Noctua fan that runs at about 11 dB to keep its temperature under 40 degrees when idling. Just a little tweak can make a big difference! Here’s a shot of my setup: https://www.mel-ler.dk/pr/florp.jpg
I came across a Satechi enclosure that looks promising. The link mentions support for Trim, but I'm not entirely sure if it actually delivers on Thunderbolt 4. Check it out here: https://www.amazon.de/-/en/SATECHI-Enclosure-Aluminum-Polycarbonate-Included-silver/dp/B0BYPVNBTQ
