TS-453 mini not booting

Hi everyone.

A week or so back I received an alert email from my QNAP telling me the fan had failed so I downed it remotely. When I attempted to restart it it did not boot.

I eventually replaced the fan as I read that if it is not reporting correctly, the QNAP will not pass its preboot test.

I replaced the original, a Y.S Tech Xtreme BD121232LB with a WDERAIR 120mm x 32mm Dual Ball 4Pin DC Computer Centrifugal Blower Fan 12V PWM Big Airflow. On paper it was a like for like, but ran a bit faster.

Replacing the fan did not help, I get 4 red drive lights, the USB light is hard on blue and the power light never comes on, so again not passing the preboot.

Of course this could mean the mainboard got cooked, but wondering if anyone has any thoughts as to what elase it could be? Is the QNAP very fussy about how the PWM fan reports speed etc and and needs something more identical to the original?

Any suggestions appreciated.

Thanks

I think it is the “Intel-Clock-Bug”

That is a long thread so I will go back and read it, but looks really interesting. So potentially it is a clock error and not related to the fan at all…and fixed by a 100ohm res?

A ray of hope, thank you.

Yes

I’ll take a look and revert thanks again.

And if it works I also have a new fan…although the original will probably still work.

It has nothing to do with the fan, the fan readout is on the superIO that is reading out wrong, due to the LPC bus degradation

Thanks for the insight guys, serves me right for going to ChatGPT for troubleshooting and not researching the forum as I used to. I was thrown by the initial fan error and went down a rabbit hole from there. Will apply the resistor fix and see how i go, but seems to be a common problem.

And just for my sanity, would I be seeing the same symptoms if the fan had actually failed?

And assuming the original was not actually the issue, should I keep using it or use the replacement anyway? It is getting on 10 years old.

A defective fan would not keep your NAS from booting or drives to show up red, no.

Noted thank you. And given I do have a replacement, is it worth replacing the 10 year old fan anyway, or just return it. Maybe keep it as a spare…do the fans actually ever fail?

A new fan would probably be nice and quiet.

Thats true, although given the PWM controls cannot kick in this one spins faster at max speed and is defintely louder. I’ll see how it sounds when I can slow it down a bit.

And probably not the worst thing in the world to have a spare on hand.

We recommend you open a support ticket with our Support team so we can assist you directly with your issue.

Since your NAS model is quite old, if needed, we might also be able to provide information on trade-in related offers.
