Actually there not loud at all. Alot quiter than fans, real quite! My next upgrade is going to be a cooler for my CPU and chipset. Ive been looking into it for some times now. And there reall not to high priced,you can get a full unit for around 150 to 300 depending on if you want your hard drives and vid card cooled to. Right now tho Im putting together a 24/7 server so Ill be adding the water cooler later on in the year. -XPerties BTW they do have liquid monitors now.lol
