Phanteks PH-TX12DX works great, friend uses with a 3770k oc'd to 4.4 nice and cool around 50c i would say, or something like the xigmatek dark knight II performs similar to a H100 or the always cheap recommendation the cooler master hyper 212 evo all great coolers
Edit: did u consider to replace the thermal paste? or do a little dusting? That cooler shouldnt be allowing the cpu to get that hot, but getting something new is always nice lol
its actually not regular water its electronics friendly liquid lol and normally does not leak.
If the cooler doesnt have enough paste or isnt seated correctly then temps will be warmer than they should. My friend was using a CM v6 gt with his x6 and stock speed and when gaming got around stock cooler temps and its because the screws that held the cooler in place to the backplate became loose.
