I recently bought the h55 and 3 corsair AF120 fans. Is it a bad idea to use the AF 120 fans instead of the fan that came with the h55? The AF120s are a little lighter, that's my concern. Could they support the weight? Also, is the fan that comes with the h55 SP or AP. Does it matter which I use? My AF120 fans all glow the same color. I'd like to keep using it if possible.
