Pros: Excellent cooling. I can feel its blowing an adequate amount of air over the harddrives. And thats on the low setting.

Cons: Cryptic instruction manual (if you can call it a manual). The high fan speed setting is kinda loud. It would be nice if you could choose your own fan, but perhaps a bit of modding can fix this.

Overall Review: You only need to plug in 2 power connectors to power all 5 drives. Either 2 SATA power connectors or 2 Molex 4 pin power connectors. Or you could do one of each depending on what you have available. To turn on the drives you have to push the small buttons to power them on. The almost appear to be led lights but they are not.

Pros: I chose this product based on its quietness and cooling effecitveness. This is one of the best coolers if you dont want a noisy case. The copper base and multiple aluminum fins ensures heat is dissipated. Just make sure you have the fan pointing toward the outtake of the case.

Cons: Pushpin design makes it feel flimsy when applying.

Overall Review: None

Pros: Best cost per gigabyte ratio on the market today. I bought 5 of these for a Raid 5 array and its chugging away.

Cons: None to speak of at the moment.
