Pros: Cools really well, have it on an FX8350. Never a temp problem, about 54C running prime95. I'm not sure how much the 2 fans add, the single fan version probably works pretty well too. Hey, I should bench mark that for temps.... Weekend project....
Cons: the double fan can be tricky to fit into your case based on clearance to motherboard, etc. But like mentioned above, the single fan variant probably works pretty well. the extra fan is probably overkill for most applications.
Summary: Excellent for AMD OC, I OC'ed my AMD FX-6300 from stock 3.5ghz to 4.5ghz modifiying vcore to 1.4v using MOBO Gigabyte 990fxa UD5. The results are amazing Idle Temps are 35°c, with prime95 stress test 5hrs wonderfull stable @ 60°c, every workers stable.
Summary: Just got this today. Two day shipping with Prime was nice. I replaced an Ultra ChilTEC cooler that had finally died on me after 3 years of heavy use and constant overclocking. After dropping to stock volts and clocks it still was running over 50C idle and over 62C while gaming.
Summary: OK, so my techie teenage son was the one who actually bought and installed it on the gaming computer he built from scratch. He's replaced most every piece it seems, as he progresses along the learning curve of custom designing computers.... But he really likes this water cooling fan!
