"...but I guarentee it is far quieter than having a fan on the GPU and CPU spinning at 18023801042 rpms."
That is exactly what I'm figuring out. I live in Arizona where ambient stays high, so I shouldn't have expected that much of an increase without chilling the water. But I just put it on the lowest setting, and it's way quieter, and it's now running at 44c, maybe because the as5 is setting, but it's cooler than what I was getting with air.
