All is ok for me now ! Corsair resolved the problem with a firmware. Now it's absolutly quiet in Silence Mode on the pump, 1950 tr/min. (2400 before) The "Balanced Mode" is functional too, at 2350tr/min. Extrem Mode : 2800 tr/min. The performance is not reduce. With a i7 4770K at 4.4ghz / 1.15v => 27° on iCue in IDLE with Silence Mode on the pump and 650 tr/min on the push/pull radiator. 43° in game ( BF5 ) Pump in Silente Mode and 950 tr/min on rad.

Do you have resolve your problem ? i have the same noise... i hear the pump in Silence mode (2400tr/min) or (Extrem 2900 tr/min) My fan are at 800tr/min. I installed 4 fans in push/pull. The two ML in the box and two another Corsair LL140 RGB I have lower performance compare to my aircolling NOCTUA NH-U14S ! When i run a OCCT test on my i7 4770K at 4.4ghz / 1.15v my system crash with the Watercooling.... by not when i use with Aircooling... After 4 hours of test, i'm very sad to see the result... Why Corsair block the pump at 2400tr/min in silence mode ? It's a joke ?? :bigeyes:
