Today we are going to look at the Cooler Master Seidon 240M which is the latest 240 mm liquid CPU cooler to hit the market. We were very impressed with Cooler Master’s first attempt at a liquid CPU cooler, the Seidon 120M, when we reviewed it back in January. It offered great value for money and was one of the cheapest all-in-one models on the market.

Cooler Master has been fairly late to market with their all-in-one liquid cooling units, compared to the likes of Corsair and Antec. With the ever increasing popularity of Corsair’s all-in-one models, it’s not surprising that they have started releasing competing products.



In this review we will be comparing the Cooler Master Seidon 240M with the Corsair H100i, H110 and the NZXT Kraken X60.
