15 months after purchase my internal fan stopped working. The fan is ok, because i tried a new one which isn't working, too.
There seems to be no valtage on the fan connectors. 

I have found that component IQ3 on DSL6450CA maybe dead but dont know what
"B0571" (n-channel mosfet, transistor, schottky diode?) is. The component L2 "1R8" (electronic coil?)
above R30 is getting very hot, too. The Rest is working so far.

Some got an idea?

seems to be normal as i found out in  https://egpu.io/forums/thunderbolt-enclosures/mantis-venus/paged/17/

IQ3 seems to bee a p-channel mosfet, but which? B0571 does not exist in any database.

@bpoh_voodoo Have you reached out to Mantiz Support directly? If not, I'd recommend doing so.

Yes i did. But support told me, that it is out of warranty. The cost would be 120 $ + 30 $ shipping for an new DSL6540CA board.
They didn't told me anything about the broken component.
I changed the possibly broken part with a p-channel mosfet IRLML2244, which made sense for me and ... tada...
it is working again. Cost of Repair 20 Eurocent.
