The heatsink only dispenses the heat and the fan cools it down. By directly allowing the fan to blow onto the VRAMs your are removing the heat a better rate.
We have done testing on it and we would not push out a product without like this that could cause serious issues to anyones video cards.

Why do you call them VRAMs? I thought people were concerned with the VRM?
ALL OF THIS.
You don't see people putting a 120mm fan direct to die cooling on a CPU and coming here to brag about how they have the best air cooler in the world.. cooling principles do not change.
VRAMs are the memory chips around the die (in most cases) a decent non reference cooler will have a heatsink on these as well, but it is probably less important than cooling VRM.
Now, some non reference coolers do not have heat sinks on the actual VRM, HOWEVER many people have raised a big fuss about this as those same coolers do a very poor job of getting cool air onto those VRMs when they are being pushed to their limits. (Believe the XFX Double D 7970 is an example, thread here
On the flip side some non reference coolers have some pretty decent low profile heatsinks for both the memory and the VRMs, like Sapphires heatsinks such as these.
I get that you are trying to sell a product, but you aren't doing yourself favors by telling potential customers that
A) You can't put heat sinks on memory or VRM
B) You don't need to put heat sinks on memory or VRM
C) You don't need a shim for a recessed die
I think the last thing you want is to find a thread in a couple of days/weeks that says "NZXT bracket killed my card" when there are heat sinks out there that can fit (or be filed down to fit), VRM and memory cooling IS important (and if someone forgets to plug in and check their fan they are baking their VRMs), and you really should have a shim... I mean you had your 7970 cooler in your hand and there is a reason the surface is not flat...Edited by Rickles - 11/27/13 at 11:55am
