First off we must say in this review that the Thermaltake Big Typhoon has a very quiet fan. At the lower fan speeds of 7.5 & 9 volts we could hardly hear it running. Also the fan we used with this Thermalright is a very basic low powered computer case fan. But that all said the cooling performance from this Big Typhoon heatsink is very good indeed as the graph shows.
