Summary: Works like a charm. Bought it to replace OEM AMD CPU Cooling fan. Was running at around 45-50C, idle, under OEM Fan, replaced it with this one and now system runs at 23C idle, 35C at full run.
Summary: Bought this used for $20, a couple slightly bent fins, didn't matter at all. This is Intel and AMD compatible, the Intel has a bracket(included) that needs to be installed and you have to take out the motherboard to do it.
Summary: I purchased this cooler about four years ago for use on a 775 socket Asus Striker Extreme board. Cooler still works, and it is as quiet as the day I installed it. CPU temperatures are great with the old e6700 chip (helped along by four case fans in a Antec 900 chassis).
Summary: I was building a computer from spare parts and my friend told me to get a new fan for the case. He thought I was going to get a simple fan, but I had other ideas. When he saw this fan he laughed and told me I bought the "cadillac" of CPU coolers. He was right.
Summary: I bought the Zalman heat sink and Fan set to replace my dead Thermaltake Ruby Orb (now discontinued). I was able to keep my AMD Athlon 64 x2 3800+ CPU below 90 degrees F and mother board temp was 85, with the Ruby Orb and the other 7 fans in my system.
Summary: I purchased this because my AMD Phenom II, X4, 965 3.4ghz CPU was running at 80-90C OUCH! I was blue screening, my PC along with my games were running terrible! This fan fixed everything! My CPU is running at 25-33c! So cool!
Summary: After starting a case change out, I ended up replacing Mobo, CPU and Ram. I must admit, once I installed this "Ferris Wheel" looking cooler, I was concerned it might be to large, but lucked out, fit fine. I really like the adjustable fan speed dial.
Summary: First time I installed my own CPU/mobo and this cooler was easy to install on an AMD A8 processor. Runs great and CPU idles at about 2-3 degrees C above room temp. Normal usage (web browsing, playing a flash game, etc.) generally runs around 3-5 degrees C above ambient room temp.
