Acasis with a thermal Pad between cooler and case. The material of the pad ensures a sufficient holding effect for the heat sink. Bring down my 970 Pro from 64 to 55 °C.During a large copy, it gets proper hot (and yes, I do have the thermal pad making contact with both the drive and the case). At idle, it feels quite warm.
So at 01:30 this morning, I ordered this heatsink. It said Sunday delivery when I ordered but it turned up at 14:00 today. Superb service by Amazon.
I've fixed it to the enclosure nice and tightly with just a couple of cable ties, I don't have any thermal pad between them.

My Studio is mounted under my desk and the drive is plugged into the back and sitting on some stuff stacked up under my desk. It's not visible.
The difference is incredible, that extra heatsink means it's barely warm to the touch at idle and during a large copy, it warms up by three or four degrees, nothing more. I have an IR thermometer gun which is what I used to check the temperature.
It's not pretty but as I can't see it, I don't care. For the sake of less than six quid, this was well worth it.
You've said already not having an Acacias but Satachi instead. Are you finding the OWC 1M2 enclosure running quite noticeably cooler?I own Satechi, not Acasis.
I bought the OWC directly from their US site.
Here are the OWC on the left, and Satechi on the other side. Hopefully these pics help.View attachment 2325571

I found the same. That's part of the reason for the mah00sive heatsink I added. I don't think it's out of spec, it's just that they do seem to run warm, even at idle.I'm just revisiting this enclosure for TM use, if it's plugged in for a lengthy time. It's odd that these NVMe's get quite warm just simply mounted but not reading/ writing.
Thanks for confirming this. It appears to reach higher temps irrespective if one drive is attached to TM or another just sits idle when mounted on the desktop. But also not immediately. I think mine got noticeably hotter (then stayed at that temp) after about two hours of merely being mounted.I found the same. That's part of the reason for the mah00sive heatsink I added.

Have a look at my suggestion just above your comment (#82)Anyone know of a good enclosure that will fit the 990 with the heatsink? Most I see won't fit it. Been looking at physotic brand
Always wondered how loud these were as I had so got used to SSD's being silent. I use two of your passively cooled variants as DAS backup drives, but they're so quick that they only get slightly warm whilst briefly attached. I do use my 1M2 for TM backups. Obviously not for the speed of TM but rather for its passive cooling efficiency when attached longer periods.OWC 1M2 is a great enclosure - I have several and think they're great!
Picked up an ACASIS TB501 recently, and the speeds you can achieve are ridiculously fast. Need to test temperatures in comparison to the 1M2, even though the TB501 has a cooling fan that comes on as soon as the temps hit 40c and above, the 1M2 have the super larger heatsink and Ive never had any heat issues with them.......
FYI you really should not be calling that other solution "Thunderbolt." While they may use a JHL chipset, they skipped the certification process, which is why they are able to offer it as a 0GB solution whereas genuine certified Thunderbolt devices cannot. The Thunderbolt brand is a trademark by Intel with very specific regulations on what and what not is allowed including specific quality metrics, testing procedures and more. Calling it Thunderbolt like you do in your title is a disservice to the actual legitimate devices that follow the rules...OWC 1M2 is a great enclosure - I have several and think they're great!
