The Scythe Susanoo was a massive, high-end CPU cooler officially launched in April 2011 by Japanese company Scythe. It was notable for its exceptional size, earning it a reputation as a "monster" cooler with dimensions of 210 x 210 x 160 mm. Its size meant it covered a significant portion of the motherboard, sometimes even partially covering the graphics card. It featured a record 12 heat pipes and weighed 1.2kg. While it performed well, some reviews at the time suggested that despite its huge size, its cooling performance was not that impressive. The Susanoo was also too large for the vast majority of standard PC cases, and was quickly discontinued.
