QNAP Smart Fan Control Does NOT Monitor Drive Temperature

[Village.Guy]

I have been in contact with QNAP support regarding hard drives in my TS-653 Pro overheating. The drives are exceeding 50 Centigrade and the system fan speed does not go above 700 RPM!

In spite of the Smart Fan menu information clearly stating that the disk temperature is monitored and fans are adjusted accordingly, QNAP Technical Support have advised me that drive temperature has NO EFFECT on system fan speed!!!!

This is actually a big deal for many users since the actual drive temperature monitor defaults to OFF when an array is newly initialised. Consequently there could actually be many thousands of QNAP arrays operating with drives exceeding 50 Centigrade their-by reducing their life span without the owners even aware..

I have requested that QNAP address this issue with a firmware update, you may wish to make a similar request!

What HDs are you using, and what is the environment like?
If the drives are indeed hitting 50C, that would warm up that enclosure rather quickly, then, those fans should be ramping up very quickly.

You would think so but that is not the case!
The drives are Seagate ST6000VN0021-1ZA17Z (SATA) 5.46 TB and the environment is 19C/20C.
System temperature = 31C
CPU = 34C
Drives = 50C
Fan CPU = 621
Fan System = 699 rpm

QNAP Support recommend manually controlling the fans!!!!!
