FriendlyElec CM3588Plus NAS - nvme's overheating (75C)

[serverlesslove]

Hi,

 

I'm trying to setup CM3588Plus NAS

3 x 4tb vp4300 nvme drives

 

OpenMediaVault updated.

 

Drives are setup to RAID5 with ext4.

 

the OS is reporting that ssd temps getting to 63-68C while idling, and likes to creep up to 75C where if I'm correct thermal throttling starts to kick in.
the SBC is in open air, no case/enclosure. room temp 21C.

 

How to find the cause and solve it? Amy recommendations setup (change the fs) etc. Thanks a mill.

Hi

 

Providing logs with

 

PASTE_SERVER_HOST=paste.armbian.de armbianmonitor -u

 

 helps with troubleshooting and significantly raises chances that issue gets addressed.

@serverlesslove, your mount options for the device might not be ideal. If the device is used as a multimedia server, then you can avoid, for example, updating file access times on each read, reducing disk writes and improving performance, using the `noatime` option. Also increase the file system journal commit interval to 120 seconds (instead of the default 5 seconds) using `commit=120`.

 

Check your current `mount` options for the device and try these:
```

defaults,noatime,commit=120,errors=remount-ro
```

@Sirmalinton Are you sure this could be the reason? I have NVME's with btrfs running with following options in fstab

defaults,noatime,nodiratime,compress=zstd,nodiscard,max_inline=0

And temperature is quite acceptable (see screenshot below).

 

I had initially set up my NAS is the standard metallic case which was quite useless. So I got a 3d-printed one with a fan on the top to keep everything cool. See my post in another thread https://forum.armbian.com/topic/48705-cm3588-overlay-for-fan-speed-change/#findComment-214042.

 

Now I don't have to worry about the temperatures at all. 

 

I must also mention that my NVME's have heatsink attached.
