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). Don't know what I did differently from other reviewers, but this fan was loud, I'm guessing 50 to 60 dB. So I experimented a little and fashioned a fan extension cord with a variable resistor in the red lead.
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.
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 it requires back plate and 2 screws thats it
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.
