I got this Antminer S7 used on eBay. I hooked it up and it was hashing at about 4TH for over a month, then one of the fans burnt out. I cleaned up the burn marks with alcohol and replaced the fan and ran it again and within a week the fan burnt out again.

Has anyone had this issue with the S7? Should I just relist it on eBay for parts?

Here's a pic of the burnt fan connector.

Are the fan plugs tight on that port? It looks like a loose connection that is arcing. Used to have that problem on the Avalon 6s

Stop buying industrial miners, running them at home, and then complaining about the noise.

It would be odd for a fan to draw more power than expected, although not impossible if the bearings are wearing out.

You might want to consider buying a replacement fan for ~$15 USD and see if the problem goes away.
