For our acoustic performance analysis we measured the noise generated by the default fan of Corsair H50, its pump and one alternative Thermalright TR-FDB fan in the entire supported rotation speed range. During the tests all fans were installed onto the Corsair H50 radiator. Here are the results:
It is really surprising that if YS Tech KM121225LB fan doesn’t make any crackling noises, then it is quieter than Thermalright TR-FDB! Corsair H50 does work in a more acoustically comfortable sound spectrum than TR-FDB, but it was the pump that in fact amazed us most. Up until 12 V it stays within the subjective acoustic comfort zone and at 7 V you can hardly hear it at all. It is the quietest pump that we have ever tested in our lab. Excellent result!
