Based on all I've read, I'd go with a Silver Arrow. The fans are better than the D14. And the SA cools better than the D14, even with the same fans. And it is cheaper. And the plain vanilla D14 does not have PWM fans.
That said, you should never get RAM with coxcombs. Samsung makes the lowest profile RAM, but RAM is low Voltage these days, so there is no excuse to get RAMsticks with tall heatsinks.
I'm not impressed with the Phanteks fan. If you have the money, of course, get a Phanteks cooler with Thermalright TY-140's (same as in the Silver Arrow) or TY-147's in place of the Phanteks fans. For Phanteks, it is the heatsink and not the fans that give it the cooling power it has.
