Fan Not Working Error. Fan is physically working

I bought a brand new My Cloud Ex2 Ultra NAS for use at home. It works fine and the fan is usually on with no issue and when I check system health it shows a working fan and it is physically working. However, I keep getting fan not working errors in the system Dash Board. Is this a software Issue? They seem to come at around the same time each day around sun set. Is it some thing I should be worried about? |2022 Mar 14 18:57:34|FAN|The system fan is not working. |2022 Mar 13 20:45:40|FAN|The s…

"Fan not working" alert when replaced fan

Hi all, I’ve replaced factory fan on my WD My Cloud EX2 Ultra with Noctua NF-A4x10 FLX fan. All works great, fan is very very silent, temperature keeps as before (if not better) but, what happens now, is that time to time (every other day or so) I am getting “Fan not working” error notification.

FAN is RUNNING BUT IT GIVES FAN ERROR

My EX2 ULTRA’s fan is running perfectly, but it gives critical error 20 which is fan is not running error. I reset the device, returned to factory settings, disassambled the battery for a while (while unplugged do dc source) tried another 3 pin fans nothing changed, what should i do ? thank you

MyCloudEX2Ultra Fan... again

I had this unit maybe 6 months when the fan error came up. Dismantled, cleaned the fan, and it’s been fine for almost 2yrs now… but fan error again. I saw a (rather useless) YouTube video about the stock fan vs a Noctua NF-A4x10… no info, not in the unit, just ran one fan on the desk, then the other. Anyways… does the Noctua NF-A4x10 fan fit this unit and work? Does it run about the same or maybe a bit better? Should I do what others do instead and mount a USB powered 120mm fan on top instead…

Replacing fan on My Cloud PR4100 - Error message received

An error message says “fan not working”. On the back of the outer case are three screws - one each side and one at the top. The cover is still on firmly after I take them out. Obviously there are other steps. Before I ruin this thing does anyone know how to remove thecase s i can get at the fan? Thanks.
