As it has been said before, this approach is the worst, because the fans are just circulating the heat around the blade. The goal is to transfer the heat from around the blade.
The problem with turning the fans into a pull config is that there isn't a seal, or anything close to a seal on the fans. They'll just spam all their pressure sucking in the non heatsink air because its so much easier to move. At least with a push config it has to go into the heatsink.
These blades seem to be a pain in the butt. I'll take one for the team. I'm willing to adopt them and give them a home.
