Intel CPUs run hot by comparison to AMDs. I'd use Core Temp to monitor the CPU temps as other software tends to give incorrect temps IME.
I would not suggest the H100 or similar Corsair or Antec or other brands of closed loop H2O coolers as they are relatively inefficient and prone to leaks that can destroy your PC hardware.
The link below shows most of the popular HSFs and a few H2O coolers for comparison. The better quality HSFs will serve most people quite well for serious OC'ing. Beyond that you'd want to jump to a premium priced open loop water-cooled system as a "hobby" or even to refrigerant cooling if you like extreme OC'ing.
You'll note that Frosty Tech supplies HSF test data for both AMD and Intel CPUs as the different heat spreader area impacts the efficiency of the HSF, so read the data for the brand of CPU you are using. Also read the complete HSF review for possible clearance/noise issues.
