Left hotfan not working

I just completed the build and run calibration. Fir fan fails and says to check wiring. I took a look and all seems correct. Is it likely that it is a dead fan with bad wiring?

Will this mean I need to replace the fan and take apart everything ?

All I can say is double check the manual, step 35:

Make sure the connector is firmly seated.

Those Noctua fans are extremely reliable, but I guess anything can fail.

Fan is only held on with 4 screws. Disassembling the extruder is not necessary.

Once you have checked everything you can, contact Support.

Thanks yes it seems like it is the fan maybe a bad wire. I will check the wires with a meter first but think thats the issue.

Just to let you know it turns out it was a faulty fan, probably the cable. Prusa support were great and got me a new fan shipped out in 2 days to canada. Got it installed and calibration complete am currently printing buddy as a test after the prusa name plate.

2 days to Canada is ridiculous! Anything I order from Prusa takes at least five days to the UK. 🙁

Yeah was crazy fast. I spoke with support on Friday and they confirmed the fan was dead. They shipped a new one Monday and it arrived Wednesday. I stripped down the parts and rebuilt with the new fan. Then yesterday I ran the calibrations and after a few trys at the first layer calibration I finally managed to get my first two prints off with little bother. 

So far it looks like my build was pretty good and not seeing to many issues.
