Summary: I replaced the stock Intel HSF with this one for a quiet build. Then I ditched Windows XP this year and installed Ubuntu 14.04. I changed cases...and realized that the old case had been hiding tremendous fan noise (some from my old graphics card, too).
Summary: In hindsight, I would rather just have used the stock system because the fins are spread apart more so it doesn't trap as much dust. I would have had my processor about 5 degrees hotter, but wouldn't have to worry about maintenance.
Pros: Cool design. Provides good balance between being cool and quiet at a decent price.
Cons: This heat sink is easily clogged with dust with where the fins converge at the base. While initially this heatsink cools better than stock, over time dust will eventually clog the fins making it worst. If you are in a dusty environment, expect periodic cleanings to keep this heatsink up to par.
Cons: My motherboard was not compatible with the fan assembly. I checked for screw holes around the cpu in another of my motherboards and it did not have any either. I am down 2 for 2. I guess I should have checked before buying.
Summary: Zalman should state that it works ONLY for a 2 hole setup.
Pros: May be a great combo,but it was incompatible with my Motherboard,so I never got to find out,lol.
Cons: (.Make sure you know how the heatsink mounts on your motherboard,whether it has 2 holes across from each other or 4 holes,1 at each corner.I picked the ZALMAN CNPS7000B-AlCu LED 2 Ball Cooling Fan & it needed only 2 holes,no provision for a 4 holer.My motherboard was 4 holer,GIGABYTE GA-MA69G-S3H...
Summary: It is definitely different from Cu version. I have both of them and tested on a same computer (3.2E prescott). It was 50 C at idle and 75 under full load with stock HSF. First I tried AlCu and it was 46 idle and 68 under load, and tried Cu and it was 43 idle and 61 under load.
Pros: Fan speed resistor is great.
Cons: It does not cool cpu very well compared to Cu version. See other thoughts.
Pros: seems like a decent cooler but unfortunately dosen't work for me.
Cons: This thing says that it works for socket AM2 (940) but only for specific motherboards that you can look at after digging around in their site zalman.com witch newegg needs to aware people about because this just wasted a week of my time.
Summary: i have 8800gts running which raised my case temps. So i decided to go with this cooler it didnt help im still seeing low 40s on load and low 30s on idle (dont care about idle much) so not much improvements, the fan was very easy to install dropping the fact that u have to remove mobo, for soccet 939...
Pros: doesn't produce alot of noise, cools the cpu, speed controller well at least for those who actually going to use it
Cons: well it cools my athlon 64 almost exactly as my stock hsf did. well ill give it 5 C off on idle ( 32), on load numbers are the same around 43-42.
