If it's the "Flex Guru FSP500-50FDB" it is just the FSP500-50FDB in black. I was planning to replace my painted black w/ modded fan FSP500-50FDB with this modded Enhance 7660B (could not find in my region un-modded), because the coil whine is so loud. The fan is also placed on the inside, so if you don't have a hole right next to it (like the k39 or S3, the Geek A30 does not) for air it gets very hot causing the fan to ramp up. Just a head's up if anyone want's to do that after waiting so long. I still got a month till 6 months so i might wait till end of July myself.all black 80+ Gold 500W
..."Anecdotal evidence" ... you would not happen to know the fan model?
