The Corsair Vengeance LPX DDR4 modules have a raised loop at the top. We moved the second fan up one heatsink fin though it probably wasn’t required.
We also tested it with a set of Crucial Ballistix Sport DDR4 modules which have a normal profile and we had good clearance.
Next, we fit the PNY XLR8 GeForce GTX 770 – Enthusiast Edition. It is a long dual slot card perfect for causing lots of space issues!
It’s close, but locking in place when mounted in a chassis, there wouldn’t be any movement and there is no contact between the card and the cooler.
