If you are shopping for a new all-in-one liquid CPU cooler, make sure you read our evaluation of the NZXT Kraken X41 before spending your hard earned money. NZXT is again on our test bench today with another new All-In-One a.k.a. AIO CPU liquid cooler system. This time we review the Kraken X41 that provides a single-fan radiator solution. As before we have a variable pump speed which is its new signature feature, but we truly want to know if it will handle a hot overclocked CPU.
