So recently I have been having issues with my QNAP TR-004 in which my 49TB JBOD resides "turns off" disconnects in a weird way. The status light turns red and the USB light stays on however the HDD light for HDD1 and HDD4 turn off and the HDD2 and HDD3 lights get very dim. I have tried swapping the placement of the drives but every single time I have this issue the corresponding lights behave this way. I have noticed that the issue seems to happen whenever I either read or write data for a long period of time.
Contained Drives: Seagate Exos X20 20TB, Seagate Exos X20 18TB, 2x Seagate IronWolf NAS 8TB
It doesn't matter if the amount of data is large though if it is then it seems the happen a lot faster. I tested this by downloading a 100gig file at 10KB/s and in maybe about 6-7 hours time the device "turned off" in this manner. While If I download something at 15MB/s then it happens in a few hours and if the device is left alone it does not turn off.
I read somewhere here on reddit that QNAP devices are known to have faulty MOSFETs and that could possible be an issue? and I found mention that if you improve cooling by replacing the fan that might "fix" the issue. I have already contacted QNAP about this issue and was told that "yes" it "might" be a hardware issue and that they would fix it for 140€ as it is (I think) about 6 months past its warranty period.
These issues started only a after I added the Seagate Exos X20 20TB drive which I recently acquired and recreated my JBOD with it. I have tested the drive with a few disk health tools and all of them as well as the "QNAP External Raid Manager" say that the the drive is healthy.
I would like to know what is the biggest, thickest fan which will fit inside? I was thinking of maybe getting one of these.
