Here is a partial listing of best coolers. All are within a couple degrees of being the same except HE01 and SA SB-E Extreme. They have fans spinning twice a fast and are therefor run cooler but are twice as loud at full speed. Controlling rpm on PWM fans is easy to do with motherboard PWM control.
It is by no means a complete list. There are more.
Cooler size comparison (Width x Depth x Height looking from front of case with motherboard laying flat)
K2 . . . . . .= . . . . 8x 6mm pipes 140x128x158mm 146x154x160mm w/ 120mm & 140mm PWM fans 43.2mm*
D14 . . . . .= . . . . 6x 6mm pipes 140x130x160mm 140x158x160mm w/ only 2011 has PWM fans 44mm*
TC14PE . . . = . . . 5x 8mm pipes 140x134x160mm 140x159x171mm w/fans, PWM adaptor included 40-45mm*
Silver Arrow . = . . 4x 8mm pipes 147x123x163mm 151x149x168mm w/Fans 40.87mm*
SA SB-E . . . .= . . 8x 6mm pipes 155x105x164mm 170x130x170mm w/ 140mm & 150mm PWM fans 31.9/39/46mm**
SA SB-E Extreme . 8x 6mm pipes 155x105x164mm 155x130x165mm w/fans Reason it's smaller is 140mm fan vs 150mm fan.
HE01 . . . . .= . . . 6x 6mm pipes 140x119c160mm w/ 140x38mm PWM fan
Dark Rock Pro .= . 7x 6mm pipes 133x124x166mm 133x149x166mm w/ 120mm & 135mm PWM fans
*cooler base to bottom fin. (add 8mm for motherboard to bottom fin.)
**fins are at 3 different levels
K2, D14 & TC14 are about same size cooler. TC14 with 2x 140mm fans can be problematic with ram clearance.
SB-E is widest by 15mm. Even wider with TY-150 fan = 170.
Extreme is 155mm wide because TY-143 fan is 151mm wide.
