That heatsink is the plastic case version:

QC has been patchy on these. I've run them for ages, and have original ones that have run perfectly for 2-3 years now.
I've known of others who have had them blow in first use, first few runs or after not much time at all.
If someone collects enough broken power boards, then they could potentially transplant working FETs from the non-blown phase onto one circuit power board.
