Hello guys, just had a small rig of gpus since 2018.  Have a opportunity to buy a couple of s17 for great price. But doing some research I seen they have a fire hazard, heatsink problems, weak psu, and faulty fans. my buddy said stay away.

If i decided to get them and wanted to overclock them what can I do to reduce risk? Get new power supply, new fan, new heatsink? I have background in computers from the 90s, i put together and taken apart many pc, cpus, heatsinks, fixed or upgraded everything at one time or another over the years.

Also for overclocking i was wondering what firmwares are legit? (ascii.to (the moon))?  I like to hear good and bad from actual users to make informed decision.
 
Thanks guys.
