Very Hot - Thunderbolt 3 Four-Slot M.2 NVMe

Hi, I almost love the thunderbolt 4 nvme enclosure, after much searching the price and performance are great. The only issue I have is heat. The nvme drives I am useing 4x Crucial P3 4TB do not reach the heatsink with the included heat transfer pads. Also the otherside of the controller board and case gets very hot in the 60C+ range. If I take the board out of the case with the nvme disks sitting on the heat sink case bottom, it works amazing. Much quieter and everything stays in the < 40C range even under load. I have ordered extra thermal pads to make it think enough, included pads are 1mm and gap is 2mm. Will see if that is enough to fix it. Otherwise I am tempted to drill a hole above fan to allow it to pull in cool air easily and quietly. Or 3D print a new top half of the case with more air flow to keep things cool. It is such a beautifly made product I really don't want to mess with it. So checking I am not missing anything. Thanks

Thank you so much for the valuable feedback and insight. Will let our product department knows, and it seems like we may need to get thicker pads for this version. =) Much appreciated, Jasper!

Thank you so much for the feedback, Jesper. We always welcome that, as they're valuable to us. In order for us to understand the issues that you're having there, would you mind taking some pics or vids to share with us here? So that we'll get a better visual before we advise from there? Normally the heat dissipation pads would do the trick, but from the message above, it seems like the pads are not thick enough to be sandwiched in an intact manner between the drive and the heatsink. Would be great if we could get a visual and let us assist you further from there. Hope to hear from you again soon. =)

The image bellow shows the gap of about 0.5mm so there is no thermal connection.

My order of thicker pads arrived today, I swapped 2 driver over and ran some tests. The drives are joined together into a 16TB drive. Below is image of idle drives, on for about 10min. You can see two drives are 8-10 warmer than other 2.

I then copied 200GB of files which warms the drives up fast. After The reported temperatures were about 62 for 2 and 73 for other 2. I then removed heatsink bottom and checked drive temeratures with thermal camera. Two were 48deg

And other two with thinner pads were 56deg

So seems that the thicker pads seems to make about 10deg difference. Photo below showing two pad types side by side. Darker blue being the new ones.

I will assemple now with all thick pads and see how it goes as long as drives stay below the 70 max recomended temperature over mult hour use I will be happy 😀 Hope that is helpful.

Hey Jasper,

I'd like to buy this 4 bay enclosure because it's quiet, so your experience is very useful for me.

Also it's good to know Crucial P3 plus are working fine in the case. What speed do you get ? did you do a RAID0 ? Could you tell me if the thicker thermal pad made the trick ? thanks
