Pretty, symmetrical and white is a tough one.
There's a low profile scythe that looks pretty badass because the fan is behind the radiator, and it's silver. doesn't have a whole lot of guts though. I don't think it would be any better than your free i7 cooler heat wise. it takes a standard 80mm fan. You could buy a white lighted fan for it and have the thing kind of blink at you as you walked by.
If you're willing to go up a few more bucks one of the prettiest coolers there is IMHO is a zalmann flower cooler. http://www.quietpcusa.com/Zalman-CNPS8900-Extreme-CPU-Cooler-P865C96.aspx
This one has a clear lighted fan, though there are cheaper ones that have black fans, and even cheaper ones with aluminum fins. Just go to newegg and pick zalmann for a selection.
all that pretty copper weighs a lot though so it's got a big back bracket. You will have to remove your motherboard to install it.Edited by bombastinator - 9/12/13 at 7:51pm
