For size comparison, here's the Noctua NH-P1 next to the 22cm wide Nofan CR-100A, the 18cm wide CR-95 Black Pearl / Copper, and the 15cm wide CR-80EH. Nofan's CPU coolers used the proprietary IcePipe technology, originally designed for large LED lamps. The Korean coolers were surprisingly light (only 783g for the CR-100A) but were not case-friendly, not to mention PCIe slots blockers.
