buildwise, the prolimatech Coolers are the best imo, very solid and sturdy.
Mounting system: Noctua's and Prolimatech are both equally good imo...
Thermalpaste: PK-1, NT-H1, and chillfactor 3 from TR are all equally good...
Pretty much every Thermalright cooler is excellent though,
Single Tower: Venomous X and Archon are the best in its class together with the Megahalems, Semipassive Coolers: HR-02 is the best. Twin Tower: Silver Arrow is the best on par with the D14.
Eventhough the fan mounting clips from the Noctua are very good and simple to use, a lot of fans are not compatible. The Thermalright ones are a bit annoying at first installation (you still get it done in a minute, just do it before mounting the heatsink) you can pretty much use every single 120mm and 140mm fan with it. Also the fans are more quiet than the Noctua Ones and are PWM...
At the end of the day, i'm just the type of guy who defends the guy (or heatsink lol) everbody is picking on, @overclock.net i was actually defending the D14 againt all the people who said it cannot compete with the silver arrow
@SnW:
The Silver Arrow is just a slightly improved, updated Version of the IFX 14, wich was released almost 4 years ago, talk about 'copy and paste'
IFX-14:
they will release a brand new designed Twin Tower Heatsink soon...
