NVME Overheated

[tommi2day]

I plugged 2x2TB Crucial P5 plus NVME SSDs into the NVME slots and started to build a new pool as traid(mirror). While running this i got overheating warnings at 66C/150F from one SSD. Both SSD have a ICYBox M2.SSD fanless heatsink. I also noticed even with nvme ssd the raid sync is very slow (~ 10%/h).

Is this a problem with the ssd and i should return or usual behavior? Can i adjust the warning levels for these drives?

The NVMe slots are likely only connected @ PCIe ×1, so their maximum bandwidth is just under 1 GBps; using high throughput NVMe SSDs are a complete waste on these low power purpose-built devices.

The threshold of SSD temperature alarm is preset to 70 degrees. When the SSD continues to have a high workload, the temperature will be high. If you want to reduce the temperature of your SSD, we recommend you to install a heat sink on your SSD.

Ups, i was not aware about this, i never expected to get NVME drives dropped to 1GBbs. This is ridiclous, the CPU should have enough lanes and even the already limited USB Ports with 5GB are faster

As i mentioned, i have alredy a fanless headsink placed on the SSD. I found in the specs, the drives will be speed limited starting at 85C. Maybe it would be a good Idea to make the threshold configurable. And add a fan to pullout all the heat of the board site at all for this class of device

The Atom SoC on the T9-450 definitely has the PCIe lanes (@ 20) to support more bandwidth to the NVMe slots, however USB 3.2 Gen1 is 5 gigabits per second, which translates to ~500 MegaBytes per second, so it actually has half the throughput versus a PCIe Gen3 ×1 connection.
