Looking at the Bit Fenix Spectre Pro from NCIX.
Blue LED
Green LED
Red LED
Plain Black
Keep in mind the onlything with color in my computer is some of the cooling on my Sabertooth z77
go green because everyone needs more "green"
Green or white. White for coolness, green for ballerness
never even heard of white LEDs lol go for that just to be unique
The Spectre Pro isn't really good for a rdaiator. The 120mm models have 1.24 mmH2O of air pressure. I would strongly suggest you go for some fans that have better air presure if you want to get the best out of your H100.
I recommend either the Corsair SP series fans (3.1 mmH2O @ 35 dBA) or, for a bit more money, the superior Cooler Master Excalibur (3.53 mmH2O @ 30 dBA). That's if you can live without LEDs.
If you want LEDs, you should take a look at the Cooler Master SickleFlow fans (2.94 mmH2O), they come in RED, BLUE or GREEN.
Air presure is very important in trying to push air through the highly restrictive radiator. Also, a fan with good air presure can be run at lower speeds and will be quieter.
