Summary: I have put on many a heat sink in my days and this was by far one of the easiest installations I've done. This heat sink has a lot of copper in it and keeps the CPU nice and cool. The adjustable control is a set and forget option - if you need extra cooling just turn the fan up a little.
Pros: Quiet, adjustable fan speed, keeps CPU cool. Elegant design.
Summary: I'm a gamer, so cool operation and silence is important to me. This cooling fan is quiet, fairly easy to install and cools extremely well. Do a little research and make certain your motherboard can house this fan, as it is larger than most. Once properly installed, it works beautifully.
Pros: Very quiet (cannot hear it over my case fans); Keeps my processor well cooled (Athlon XP 3200+)
Cons: Large and heavy; It took a bit of work to make certain it was securely fastened and in good contact with the processor.
Summary: I found this fan to be an extremely quite and efficent. I could hardly hear the fan when the cooler was in operation. The only bad thing about this cooler was the installation. The motherboard had to be removed in order for the fan to be installed.
Summary: It cools great and even at top speeds is very quiet - as quiet as I could ask for. However, the size is the killer for me. I can't swap drives in & out without removing it. It's in the way of plugging memory DIMMs in & out.
Summary: This fan is a monster to say the least. I am building an HTPC and I wanted a good, quality CPU fan that I could get low noise from and also keep the CPU within it's operating temperature range. Luckily for me I have a large case in the Lascala 20M and it fits nicely.
Pros: Large fan diameter and large copper fins for heat dissapation. FanMate2 speed controller lets you slow the fan from normal speed to "silent" mode.
Cons: VERY large in diameter. Slower fan speed may scare off overclockers or gamers.
Summary: It is a very cool looking CPU fan. Good cooling. Comes with a fan controller to lower the noise level to whisper quiet. It is quite heavy so be careful if you move the computer around a lot. It comes with adapters for socket 478, 754, and 939.
Pros: Very quiet. Great for HTPC. Cool looking.
Cons: Very heavy. Be careful when moving your computer.
Summary: I dropped this on on a xp64 3200+ with a ASUS A8N-VM CSM mobo in a Ahanix 601 case with plenty of clearance to spare all around. AMD cool 'n' quiet utility and the ASUS q-fan control (in the bios) both seem to work well; of course you can also just manually set it to silent with the fan-mate...
Pros: Great heat sink while still fitting on some tight mobos; priced very nicely!
Cons: It's well over AMD's recommended cooler weight; fortunately socket 939s are almost "crunch" proof.
Summary: Even though my case is crowded (MB close to my PS) I was able to fit this baby in. You could even bend the copper fins if you needed to (they flex). Fanmate is a set-amd-forget for me as this PC is my DVR. Now all I hear from my case is 2 HDs.
Pros: Near silent with the fan mate. Was able to fit it in a cramped case easily.
Cons: You have to screw it into an aluminum clip under pressure. That means it's easy to misthread the screw into the clip before you know it. Be careful!
Summary: this cooling fan is very quiet under silent mode. but the temperature of the cpu is around 50C idle and 60+C loaded. I was expecting better cooling performance. My motherboard can control cpu fan speed. But I am not able to get it to work with this cooling fan.
Summary: The Zalman CNPS 7000B AlCu is a very nice cpu heat sink / fan. It cools my AMD Athlon XP 2500+ cpu (overclocked to 3200+) very well. My only complaint is that it isn't silent; air turbulance noise, when the fan is undervolted using the included Zalman Fanmate2, is minimal.
