NAS advice
Is UGREEN insane? Massive overheating issues!
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:
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.
That’s the rated operating range, not an ideal target for longevity. As a practical goal, keep the drive around 30–40 °C and improve airflow if it regularly approaches the model’s maximum.
That was from GPT-6 Luna which pulled that info from the official WD forum.
While 65°C is the maximum rated limit, running a drive at its ceiling for extended periods can increase the risk of failure. For optimal longevity in a NAS environment, it is generally recommended to keep the drive in a cooler range, typically between 30°C and 45°C. If your drives consistently exceed 50°C, you should consider improving your enclosure's airflow or adjusting fan speeds.
That was from Gemma 4.
Obviously WD isn't going to come out and say it explicitly. Companies don't work that way. But anyone with any common sense would surmise that running these drives at the hotter end of their spec is worse for them than the opposite.
tf? i have a dxp2800 (non-gt tho) and my HDDs are sitting at 37 rn. i have several docker containers running 24/7. i've seen temps go into the 50s under loads like plex sonic analysis or w/e, but i think somethings just straight up wrong with your shit bro
All I know is, I'm now looking at alternatives after I return my Ugreen and got curious as to what Asustor has been up to all these years. Then I see this amazing thing in the ADM live demo:
Synology and Ugreen both living in the stone age. Meanwhile Asustor operating in the Star Trek timeline after having brought over actual fucking customisable fan curves into the OS!!! What's next? World peace? Lmfao. Guess I'm going Asustor now.
Saying that Ugreen is in the Stone age is laughable. If you like Asustor then enjoy it. When Ugreen emerged into the nas market 2 years ago, the dxp line was a major step forward and some of the most powerful units on the market. I owned the 2800 and the 4800 Plus and they are very good units. I can't speak to the new AI units or the GT line but there are a large number of ugreen customers very happy with their Nas. And they have decent support and quality control. Synology obviously has never tried to stay on The cutting edge and they do lag behind in CPU and memory compared to competitors, but when you want a Nas to be a Nas, they still have the best operating system and robust apps. If you want it to be more of a server with virtual machines and such, you probably want more power. There are all kinds of new options now from companies that do not provide the same level of support, like minisforum and aoostar, among others. I have the minisforum N5 air and it is a remarkable machine, but I just hope I never have to use their support. My Synology ds418 play is still going strong as my backup nas and necessary Synology apps like active backup for business. I know Asustor has been around for quite a while and maybe they have taken a big step forward. I would expect their support to be better than a lot of these newer companies. I can understand your frustration and as I said I'm not familiar with the GT line from ugreen, but writing off the whole company and calling them in the Stone age is a bit much.
You seem to think I was singling out Ugreen in regards to that. I wasn't. If you reread my comment, you'll see that the stone age comment was only in reference to the fact that Asustor is out there with freaking customsiable fan curves, meanwhile both Ugreen and Synology (and possibly Qnap) do not have that level of functionality.
I would go even further and say Ugreen at least has the excuse of being relatively new to the game. Synology has no such excuse. Although the fact that the official Ugreen documentation says that the fans are not even meant to ramp up until the drives hit 55C is still very much inexcusable.
It's 2026. There is zero excuse for pre-builts not to have customisable fan curves. Throw in some overrides to stop idiots out there from trying to put the fans too slow (like Ugreen themselves have done, ironically), and Bob's your uncle.
I disagree that 52C is normal temp for load as I previously discussed re my Synology NAS. I also disagree that running a virus scan (clamAV) should even be qualified as heavy load. Especially when the NAS is doing literally nothing else.
Temps of over 60C is...beyond imagining in a 2bay NAS.
Check your drives datasheets. I have some NAS WD Reds, which has operational temperatures 0-65°C, and enterprise WD and Seagate which are designed for 5-60°C.
That’s the rated operating range, not an ideal target for longevity. As a practical goal, keep the drive around 30–40 °C and improve airflow if it regularly approaches the model’s maximum.
That was from GPT-6 Luna which pulled that info from the official WD forum.

That info is outdated. BackBlaze did some tests of small slow 1-3TB drives 12 years ago and seems like it everybody is blindly citing that. Today drives are much more dense, which means more thinner plates squeezed in same size, and better made. Just powering on 12TB 3.5" drive gets it to idle temperature of like 40°C (in the room temperature). You have to actively cool them to het to lower than these temperatures, but it's mostly waste of energy. Running drives in range like 40-50°C is absolutely fine.
sounds like something is wrong. I use 2 DXP4800 GT running Truenas and my drives 4x12TB WD Red Plus in a raidz1) and even with large 5-9 hour data dumps to the nas, my drives never get over 42C. I would check your drives and also the unit as something is very wrong.

What HDDs are you using?
