HS-453DX high disk temperature

Post by KonradM » Sun Mar 01, 2020 7:17 am


I am running HS-453DX-4G system as a media server ( Roon + video ) + some Qsync.
The system is up 24/7.
I am registering disc and system temperature around 55-65 deg C all the time. (
I am using 2x WD HDD 8T ( RED) and 2x M2.SDD 256Gb discs. I'm affraid, thet HDD will not last long. The rest of the system is at similar tempareture level.
The unit is standing in a normal rooom temperature ( below 25degC ) with plentu of air around,
While I understand that fanless system will be a bit hotter, this does not seem to be a normal situation.

Any ideas what can I do except shutting system down frequently? I tried to put HDD in sleep mode after 5 min inactivity but it does not seem to work.

this unit is designed at the thermal limit..high disk temps were reported before..best not to buy such a system for prolonged use

either switch to a different unit..or think of a way to cool it better (little usb fan pointing to it?)

HS-453DX is passive cooling. My TBS-453DX has a fan in it, so i feel that is better in that sense since it's pushing hot air outside... whereas yours doesn't quite do as good a job as that.

i noticed that even the new qnap switch not only has a big heatsink in it, but also a fan to boot. so yeah... it helps especially for 24/7 usage.

also which m.2 ssds are you using? not all are created equal. My mx500 passed the test for continous usage in regards to temps. but some m.2 ssds they don't handle well for long usage :S

SSD CRUCIAL MX500 CT250MX500SSD4, M.2 (2280), 250 GB, SATA III, 560 MB/s

I do not use this system extensively, do the disc activity should be low. Looks like some processes prevent the discs to go into sleep mode.
Within one hour from restart after cooling the unit down to the room temperature I have 52 degC had again. Nothing was requested from the server (no media content used ). Just running idle with hdd standby set for 5 min.

Does anybody have such a problem with hs-453dx?
It was advertised by nap as a silent desktop solution with passive cooling system that keeps hdd at reasonable temperature. 55-60 deg C does not sound as reasonable!

I have:
2 x 8GB RAM A-Data
2 x M.2 SSD 1TB (43*C)
2 x HDD WDC RED 4TB (45*C)
CPU 51*C
system 44*C
QTS Build 20200402

Did you use coolant tape before installing the SSD / HDD? Maybe you should replace them with new ones

I also used the WD Red 8T before, which is an air filled hard disk, and the temperature is easily over 55 degrees.

I changed to a pair helium filled WD 8T now, the temperature remains around 46 to 48 degrees now.

Also WD Red 4T should have lower power consumption.

You can reference the WD Red hard disk spec here:
