Noctua NH-D14 vs Thermalright IFX-14 - Tested on S1366 Core i7 920
 

As you will see, the new Noctua flagship solution is one step ahead of Thermalright IFX-14 in all test modes. In quiet mode with one 140 mm fan NH-D14 is 3°C more efficient than the competitor, and in almost all other cases – 2°C more efficient. With two Thermalright TR-FDB fans that suit IFX-14 the best, the difference lowers to 1-2°C, but the victory still stays with Noctua NH-D14.

Noctua is the new king of Air cooling I guess...but should we start thinking what can water cooling do at that price range?

H50 from Corsair is the only alternative at the price, unless you go fully home made (only buy the WB, get everything else from ebay/other sources);
