Fan noise & motherboards

I'm not disagreeing with you in any fashion. I was trying to acknowledge that your motherboard has some great option for controlling your fans. I thinking that those options will be helpful to many that have the same options in there bios.

Got it

Well I'm thinking the sound is normal as it isn't doing the gurgling sound, just a constant hum. It's not over powering though, and if I'm not listening for it, or have some other noise going one - gaming, music, or even concentrating on something else, I don't notice it.

Still, when quiet down the other fans, and all you hear it he pump fan it gets your attention. Anyway the system is a lot quieter since moving the case fans to the other fan headers on the motherboard :)

And yes, PWM with BIOS control works like a champ

A constant hum? That may be the norm for your pump. I'm sure you have checked all fasteners, mobo standoff's thing like that. I'd pop the pump apart and deburr the impeller, see if I could check it's balance. That's just the crazy stuff I do, not really needed.

The two different Corsair pumps I have used, a 80i and 100i were very quiet, I had to put my finger on the pump to tell if it was running. From the number of noise complaints you see at the Corsair forum I got luck I guess.

I bought a pair of high end Aquacomputer D5's, those I can hear!
