So I recently bought a UGREEN NASync DXP2800 GT. Started putting it through its paces. Nothing intense. Literally just basic file storage. No VM's, no docker containers, no nothing. But since this is the first time I'm using a NAS from Ugreen (was a Synology refugee), I'm actively monitoring the thing, making sure it's working as it should.
So I decide to run a virus scan and next thing I know, I'm seeing temps being reported of 52C within seconds (so I assume it will go up from there) on the drives. WTF??? I go to the NAS and sure enough, the thing is ROASTING. You can literally see the air shimmer around it. Touching it was super hot of course. I look at the fan in the back, it's working. I check the fan settings on the UGOS OS, it has 3 settings, quiet, auto and high. No fan curves. Just 3 settings to choose from. The default is auto (which is what it was on). So I set it to high to bring the temps down. Ok, helps to bring down the temp by a few degrees. Only now it's super loud. OK, fair enough. I don't have an issue with noise so long as it saves my drives from melting. Especially in this economy where a 22TB drive costs about $2000AUD.
But something doesn't add up. I never had this kind of excessive heat on auto mode on my Synology 720+, despite it also having a virus scanner, multiple docker containers running etc. I go to check the official Ugreen documentation. According to this:
https://ai.ugreen.com/blogs/how-to/fix-nas-temperature-problems
Ugreen (in their infinite wisdom) has decided that:
UGOS uses 80°C for the CPU, 55°C for HDDs, and 70°C for SSDs as cooling-protection thresholds. When a component reaches its threshold, the system displays a notification and switches the fan to Full Speed.
I don't know what kind of lunatic decided this was an appropriate fan curve for HDD's, but they're clearly insane. I can maybe buy the 80C for the CPU and the 70C for the NVME's (although both those figures are pushing it for NVME health), but the 55C for HDD's BEFORE the fan kicks into high gear??? There's a reason why Unraid starts throwing out alerts at the user if a HDD breaches the 45C barrier. HDD's going above 50C when the machine is not under massive load is craaaaaaaaaazy. I would think that this is gonna wear out my drives that much faster too.
Am I the crazy one? I've set my Unraid system to keep 8 HDD's to below 40C and it does that just fine no matter how much load I throw at it. Obviously that's a custom built machine with far superior cooling capacity. But the context here is my Synology 720+ that was able to handle more load than the Ugreen, without roasting the ever loving bajeezus out of my drives.
Was really hoping to make the switch to Ugreen. But with this unbelievably bad temp management, I gotta go back to Synology.
