For that price range, your best bet will be Enermax ELC120 Water Cooler or if you can increase the budget, for a little more you can get Enermax ELC240 Water Cooler. I have had personal experience with both, they are both fantastic. The liquid coolers ELC120 and ELC240 are based on a close-loop system with pre-filled coolant that is designed for a reliable and leakage-free operation over long years. Therefore, Enermax does not compromise on quality and durability. The robust ceramic bearing of the pump ensures a stable and low-noise performance. To avoid the evaporation of liquid, the manufacturer relies on a seamless tube made of FEP (Fluorinated ethylene propylene), a highly resistant and at the same time flexible material. A well-thought mounting system ensures a quick installation and perfect contact force with the CPU. The Enermax liquid coolers support all current Intel and AMD platforms.
