the PCPS is perfect

i installed it today and it's even quieter than my WD green powers and as loud as some scythe s-flex @600 rpm (= still audible but not as loud as a completley decoupled laing)

i am used to VERY silent rigs and what kept me from watercooling all the time was the noise coming from the pumps; while laing pumps are very quiet they can't go as low as some 120mm fans or quiet hard disks...
