Fan-spd,90 it's a fan speed with 90% you can replace it with 80% or 100% to try if it fixes the issue.
Do you know why an avalon 1166pro fails to start hashing after a firmware flash? The first time i ended up having to order a new control board and it fixed the problem and after a few weeks i flashed it with upgraded firmware that was emailed to me from canaan and now it just boots and says IDLE in the webui it connects to the pool just will not start hashing.
Canaan has been horrible with customer service i dont understand how you can sell a machine at such a high price and just brush off anyone who asks questions. at the very least they could give the tools required for people to diagnose their own machines. canaan told me if i buy a lot of machines i get support and warranty. im not rich and this is truly a hobby for me and i have bled about 15k so far on mining equipment in the last 6 months.
My avalon experience lost controlboard after 3 days(had to order from ebay for $300 canaan wouldn't sell me one), lost a hashboard after 3 weeks, lost whole machine now after 8 weeks. I wrote canaan it was under warranty when they ran the serial number but there was so many steps to get it returned and they wanted me to remove the hashboard and heatsink which i started doing but they put thermal paste all over every part of that board even the slots on the case the board slides into. So many steps as in (let us remote to your machine, disassemble whole hashboard, waybill, give us your company full information(im an individual), ship, insurance, wait time etc)
I even found a broken drillbit that was used to drill the holes in the avalons enclosure stuck in the fins of one of the hashboards. I know it was for this purpose because of the size of the drillbit and it still has 4 or 5 rings of alumnium attached to it.
