Prime Cooler Hypercool III+ & Hypercool 4+
 

Basically the Prime Cooler Hypercool III+ and Hypercool 4+ are both good coolers for midrange overclockers because it seem that it can't handle the heat for higher overclocking. Although these coolers are huge in size but the installation isn’t that hard. I found that it is quite easy to use for all kinds of sockets. Besides that, these coolers are silent, universal (Hypercool 4+), and its ablility to cool down not only the processor but other motherboard components (MOSFET) as well. With its acceptable price, I would suggest you to try it if you're looking for a silent CPU cooling solution.
