hi there. this is my first post here. i just wanted to know if this is enough heat sink for 2 3886 chipamps? the enclosure is an empties dual 31 band EQ so there is plenty of ventilation. Also i'm not opposed to putting in a small fan to help if necessary. if this isn't enough, would the 9.95 one at apexjr.com be enough for said purpose? thanks. any help is appreciated.

That eBay one would probably do for a single LM3886, but would get pretty hot. I would suggest the $20 "gold" heatsink from apexjr if you want to do two LM3886's on one heatsink. Although, for the price, the best solution would be two of the $9.95 apexjr heatsinks, one for each chip.
