Compact And Nice: Evercool CUC-610
The CUC-610 from Evercool is a relatively compact aluminum cooler.
Its underside contains an inlaid copper plate to better distribute the heat. A screwdriver is needed to install this cooler. It's a difficult and even painful process to get the clip to engage with just your bare hands.
Its cooling capacity is at the same level as that of a pure aluminum cooler. The noise level it generates is still bearable at 54 dB(A). The CUC-610 has not been designed for overclocking; in everyday use, though, it works admirably.
