The Phanteks and SB-E aren't just close but also beat the original H100. The H100i easily beats the original H100, whilst being quieter and the new H110 improves on the H100i by another 5C and is quieter.

When they finally start using copper radiators and quality hot plates and pumps we will finally see traditional air coolers dethroned.
