SilverStone released their latest Permafrost AIO Liquid CPU cooler series, featuring integrated addressable RGB lighting. The Permafrost series is available in 120mm, 240mm and 360mm radiator sizes. Today we are going to review the Silverstone PF240-ARGB AIO liquid CPU cooler with a 240mm-sized radiator. Personally, I don’t like an AIO with a 360mm radiator for a CPU cooler because I find it too big. I don’t prefer the 120mm as well, since it’s a little bit inadequate specially for mid to high end CPUs. The PF240 comes with an MSRP of $99 USD, it’s relatively affordable and not that expensive for a liquid cooler. But how does it perform? What kind of performance do we get from a sub $100 CPU cooler?
