Re: Antminer D3 overheating AFTER cleaning the hashboard and removing the dust
Yes, honestly last time I opened it, it wasn't this dusty! 
After I brushed the dirt off, I used a blower to blow off any residual dust. Could you please recommend me a contact cleaner spray? Is this ok https://www.amazon.com/WD-40-Specialist-Electrical-Contact-STRAW-SPRAYS/dp/B00CMT9TFY/ref=sr_1_fkmr3_1?s=industrial&ie=UTF8&qid=1520721398&sr=1-1-fkmr3&keywords=PCB+contact+cleaner+spray ?
Thanks!

Thanks!
that product is perfect...doesn't have to be a premium brand contact cleaner, maybe your local electrical supply store stocks a cheaper brand(just check labeling and make sure it states for PCB boards) good luck
So, I used the contact cleaner to clean all the boards and plugged it back in. In less than 2 minutes of the ASIC booting, all boards were over 100c!! I am sure I didn't damage the cards while handling. Do you think using compressed air might have damaged some temperature sensor on board? Please help me!
