I second amuffin. You should consider the best Air coolers instead, they're still cheaper than the H100 and performs better, safer.
You can check out these coolers, there are plenty of reviews and comparisons of them on Google.
Phanteks PH-TC14PE
Thermalright Silver Arrow Extreme
Noctua NH-D14
Though if you absolutely have to, the Cougar VortexHDB 120mm PWMs seem to be the best bet. If you don't need PWM, go with a Gentle Typhoon 1850RPM.
