Ok, I'll admit this, despite having a look round I'm still pretty much out of the loop on cooling and I'm going to be building a Haswell system this week with luck 
So what I'm wondering is, what coolers there are that are both quiet, and don't weigh enough to need a forklift to move them?
I'm going for a 4770 of some description (probably the low power one as I have no intention of overclocking), and want a cooler that is as close to silent when the system isn't playing games etc as possible
At the moment the loudest thing for my current Q6600 is the external HDD when not playing games.
The most likely motherboard is the Gigabyte Z87X-UD3H
I'm stuck on what cooler to get that is fairly good (no overclocking!), quiet (important), and preferably has a fan that is easy to replace.
Relatively cheap would be good
Easy to fit would be great.
I am tempted by one of the ready to use water cooling type units, but don't really want to spend £50+ on the cooler, and I'm leary of the fact they've got pumps which if they fail, the the whole unit needs replacing.
