Innosilicon T3 hashboard repair

[smracer]

Hey guys. 

Yesterday.  5:30am power prices spike so my farm shuts down.  2 exhaust fans were left on.

Started to rain a little and humidity spiked.  Fans were bringing in humid air and all the miners were still hot.

8:30am power prices came down and the farm restarted.

I instantly lost 25 (out of 200) Avalon 1047 PSU's and around 30 Innosilicon T3+ hashboards. (out of 195 hashboards)

The hashboards almost all had the same chip blown.  This little BOOST_MP3426 board looks like it is removable.  Does anyone know what could have caused this?  Was it moisture?

I have added a humidity sensor and the farm will not restart after a humidity spike until humidity < 70%.  Also all fans now shut off when the farm shuts down.  Does anyone know anything about this chip?

The image shows that it has lots of dust and since humidity makes dust adhere to one another it could lead to a short circuit.

You should have monthly maintenance for these units and I think filtering your air intake will help reduce dust and humidity.

And MP3426 is replaceable you can buy this chip on ZeusBTC from here https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=1182
