I'm testing it right now with a few different fans. I'll see about posting a full article on the site this week. So far, yes you can improve performance if you are willing to accept more fan noise.I was looking through the charts and I noticed the Cryorig C7's were using just the stock fan. If testing is still being performed, have you considered getting TheHack's 3D printed adapter mounts (92mm and 120mm) to see if temperatures improve at all with non-stock fans? I just might consider one if Dan's fan takes a while to release since the teaser trailer just hit.
I am as well. I would think a duct would be better than a simple hang-over adapter since it would allow a 120mm fan to pull about as much air through a 92mm spacing as it can through a 120mm spacing. I might actually consider switching coolers to make RAM installation easier because it will be quite hard having to remove my IS60 just to access and remove my current DDR4 2400 memory to eventually upgrade to DDR4 3600 memory in my Ryzen system.I'm curious to see how it will perform with the duct.
Um, even in that link the Cryrig C7 is still out preforming the Noctua L9i. (The chart I was looking at is the same on on page 1 for this thread)
