Pros: VERY QUIET. You can't even notice that it is there. Price. Comes with all required hardware including an adapter to go into a standard 4 pin power like the one for your IDE Hard drive and CD ROM drives.

Cons: Low blowing power. Very short wiring. If your going to use this for your case fan on the back (near CPU), make sure you case fan plug is near the CPU. Some mobo (mine (ASUS)) the case fan plugs are near the IDE connectors. So the wires will not reach it. I'm going to extend it by using my old wires from the old fan and splice the wires, however, it does come with the adapter in case if you run into this snag and have an available power connector.

Overall Review: So i went with this product b/c of price, quiet, and brand name. I have another PC (very old) with a cool master fan and that thing is still kicking after at least 4 years in service with zero problems, however, the low blowing power dropped it down to a score of 4, but hey, maybe that's why it's inexpensive? I would highly recommend a Cool Master fan and will purchase others in the future.

Pros: EASY installation- you can use the existing intel 4 clip HeatSink holder. Super quiet. Holds my intel P4 2.0ghz process at a low temp. Really cheap.

Cons: worried about quality due to price being low. if it lasts for more than a year, then it was worth every penny.

Overall Review: newegg rocks, FAST SHIPPING ALWAYS!!! Have purchased many items from newegg and looking forward to purchase more.

Comments: Just like everyone says, its very quite, it is a bit heavy, and the best thing about this, has many connectors and a power switch. No more unplugging the power cord to add or remove PCI cards, CD-ROMS, HDD, etc. YYYEEEEEAAAAAAHHHHHHH!
