I wouldn't advise any of the Jet Series by CoolMaster they are all looks and no proformance. My opinion is to stick with the well-known manufacters like Thermalright & Thermaltake. These I would say these are the best heatskins, I use Thermalright XP-120 with a Antac 77CFM Fan (Getting a new fan soon, Ytech 127CFM) and Artic Sliver 5 Paste but keep in mind this heatskin is massive but apart from that I does excellent for cooling just look at some of the reviews made, top marks.
My temps are around 44C when browsing the Internet and Downloading etc, when playing games it tends to stay around the 50C area although I have not had the PC running for a constant 200hours which is recommed by Artic website for optimaluse.
Hope this helps.
