My main desktop machine has an Icy Box caddy fitted with 4 x SSDs. The
caddy fits into the space of a DVD slot so very useful.

I have finally got round to removing the very small fans because of noise.
Only been running for a couple of hours but temps are 22 degrees for all 4 drives, with fans fitted it was 20/21.

Seems to me this is well within limits. Is anybody aware of a monitoring software that would keep a record of temps every 30 minutes or so?

Many thanks.

Unlike HDDs, SSDs burn most of their power when actively doing reads and writes. So unless you're thrashing them doing a RAID rebuild or something
they aren't taking much power. You can look up the specs of the SSDs which will tell you their operating temperature range. In general SATA SSDs are
low enough density (watts per cm3) that active cooling isn't needed - the
metal drive chassis is a good enough heatsink.

The SMART data should tell you the drive temperatures - I don't do Windows
but there should be tools to plot that information.

SSDs supposedly don't like to be actively cooled anyway, they like a certain amount of heat to ensure written data is durable.

HD Sentinel is the best SMART monitor that I've found. Not free, but pretty good value, especially the five-license deal.

Many thanks for the replies :-)

I ran AS SSD benchmark and it pushed the temp of the SSD I was testing to
30 but it dropped back to 25 after the test.

I left HW INFO on overnight and the temps were 25-30 for the drive I
tested, 25-26 for the others, the overnight backup doesn't seem to have
caused an issue.

The NVMe that the Z170K boots from shows 30 to 34 but the second NVMe
which is on a PCIe card doesn't show up in HW INFO or in Crystal Diskinfo although it does in AS SSD benchmark, perhaps being in a card hides the
sensor?

There should be no difference[*] between an M.2 stick being plugged in
direct, and via an adapter. But it may just be that that stick doesn't
offer the temperature via SMART.

Anyway, if you aren't reading temps in the 70+C range there's not a lot to worry about.

[*] Technically, M.2 and PCIe cards have SMBUS pins where I2C temperature sensing chips can be connected. Some motherboards can read these, others
can't - but eg servers use them for chassis temperature management.

I suppose it is possible that your adapter doesn't wire these through, which would show a difference compared with being in an M.2 slot. Although in general there is not a standard way to find out which sensor relates to
which drive (only the BIOS or BMC knows), so I would be surprised if tools
like CrystalDiskInfo will show these sensors.
