Summary: I read the one review about this product that said his fan blades were hitting the heatsink, and thought, "That sucks. I hope mine isn't like that." It was. I purchased this CPU fan brand new a couple months ago, and finally got around to putting it on my computer last week. However, when I took it out of the box, I did a preliminary spin of the fan just to see.
Summary: Bought this from Amazon.ca for 22 dollars, total was 44 dollars with shipping, brand new, keeps my A8 3870k at 15 to 18 degrees idle and 45 degrees Maximum. Build Quality is Stellar I just felt great buying it because of the premium construction.
Summary: I've been using this fan for a couple months now and it does a great job despite the fact that I'm overclocking my system. The CPU is currently at a decent 31°F. It also has a nice green light that I can see through the window of my casing, which I thought was a nice touch. It was a fairly easy installation, however the bars are placed a bit oddly so I had trouble mounting it to my MSI motherboard whereas my first fan was much simpler.
Summary: WARNING: This CPU cooler is HUGE! I have a 2003 Lian Li PC-70B aluminum case that I love, and this is my 3rd system build in it. I wanted something better than the stock HSF that came with the AMD Phenom II X6 but I wanted to be sure that it would fit in the case. CPU coolers seem to get bigger every 2 weeks so I did quite a bit of research before making the decision. I don't overclock because my CPU, RAM and SLI setup can handle all of the games I play with no problem.
Cons: I'm not sure if it's just my motherboard, but I had a hell of a time getting it clipped on. It fits VERY tight on my board. Took some muscle to get it in place. The thermal paste it comes with is pretty thin and watery. Works decent. I'd recommend buying something else such as Arctic Silver or MX-2.
Summary: I have this heatsink installed on a i7 2600 running at stock speeds in an antec 902 v3 case. The temp in my room is about 27C, and on idle my cpu temps are at an avg of 33C that's only 6 degrees warmer then my room, on full load it does not go past 58C. I bought the heatsink primarily for the fact that it looks amazing, and it keeps my cpu cooler then the stock fan, so win win.
Summary: I don't think that I exerted any major pressure on the heatsink fins around the fan, but the fan wouldn't spin due to rubbing against the fins after the fairly difficult installation. Perhaps I somehow bent it during installation... It's still cooler with my case fan than it was before installation, so I'm thinking of keeping it. UPDATE - I found the part that had bent during my installation.
Summary: I was using an Arctic Cooling Freezer 7 Pro for a long time, but my processor's overall temperature was about 50 degrees idle. Under a load the same processor (Intel Q9400) was running well above 60 degrees. So, I bought this Zalman and I'll never go back. The installation of this heatsink was very easy in comparison to any other I have installed. And since installing it my processor has never gotten past 50 degrees.
Summary: I upgraded to this air cooler and have been using it for about 2-3 weeks now. After many runs at loading the CPU i saw my load temps drop an average of 10-15 degrees Celcius. idle temps are even better...products does as it says. Be very careful when you install...The cooler has a lot of sharp edges, so take care...also be gentle with it.
Summary: It has an amazing performance. Not too loud (I got 3 other fans in my case which are much louder). Fits perfect in my AM3 socket. Temps drop down from 42-48C(stock cooler) to 26-34C in normal applications. When rendering (3ds max) doesn't surpass 46C, with stock cooler when I was rendering I got 55-63C. So I'm very happy with this great cooler. Zalman is one of the best cooler brands you can find. 100% quality.
