Not sure which Corsair Hydro Series CPU liquid cooler I should get (H55 or H100i)

I have been looking at the H100i for a very long time. Looks promising, however, my friend is getting the H55 and he asked me why I am getting the H100i when I can get a H55 for $50 less (compared to H100i being $100)

I'm not going to overclock, but which liquid cooler should I get? Both coolers work with my build, but I worry about my computer's temperature.

I'm getting an i5-6600k and possibly a Nvidia Founders Edition 1060, possibly because I may just get the 1060 instead of the Founders Edition (if that helps in terms of how hot my pc will get)
The case I'll be getting is the Corsair Air 540

The 6600K is not known to be a particula hot chip so with an H55 you're going to get 4.5GHz out of it pretty easly I think. But surely you're going to run it faster than the H100i so would be a bit noisier. To be honest you should pick up a 50$ air cooler (Cryorig H7 maybe) to get better acustics but sacrificing a couple degrees.
Those are just my opinions.

The air 540 has tons of space for AIO water coolers. But if your not going to overclock the h55 would be fine

I have the h55, the stock fan is loud. Had an 4.5 ghz oc on my 750k
