MASSCOOL 7WD04L3 120mm CPU Cooler

Pros: This thing is an excellent CPU cooler for the price. It brought my (100%) load temp. from 125F to 105F, with typical idle temps down from 100F to 90F. Not only cooler in general, but a tighter range of temps, which also increases the lifespan of the processor. The blue LEDs in the fan are nice touch, and it's very quiet. Also, with my motherboard anyways, I was able to orient the fan so the air blows to the back, allowing it to work WITH the overall cooling system of the chassis.

Cons: None really.

Other Thoughts: This things is very large. I have a huge chassis so it's not a problem, but you might want to check whether you have room for it before you buy.

Pros: Quiet and Cool. It keeps my extremely overclocked amd 5000+ in the 38-42 degree range. The 120mm fan looks cool with the blue led lighting.

Cons: Size, this thing is huge and may not fit into some mid tower cases. The L shape could hinder some ram slots if they are too close to the processor. That's not really a con for the heat sink, but something to keep in mind.

Other Thoughts: Overall this is a good product, just make sure that you have the room for it in your tower.

Pros: 5 single-ended heatpipes feeding a huge aluminum-finned heat sink. The L-shaped form allows orienting the heat exchanger right in front of the case exhaust fan, thereby eliminating one of two fans to reduce noise. The fan is attached to the heatsink with almost-rubbery standoffs, which just about eliminated all fan vibration transmission to the heatsink. This fan is really quiet.

Cons: The heatsink is really big. Some cases won't fit. I was trying to retrofit this thing and a new motherboard into an old P4-based Gateway microATX box. The heatsink was just a little bit too tall for the installation. So you do need to measure things first.

Other Thoughts: The L-shaped form (with the heatsink on one leg and the cpu pad on the other leg) is really easy to mount on the cpu. However, it also can slide a bit. You might want to find some rubber band or high friction fabric to insert in between the hold-down strap and the heatsink pad to keep it from sliding around the top of the cpu.
