Pros: Max RPM 3400. Moves a lot of Air. Easy Install. Great price when bought in bulk. 80mm Fits most CPU Heat Sinks.

Cons: At 100% these fans can be loud. I would compare them to a Electric Toothbrush or a Electric Razor/Clippers. *No Screws Included

Overall Review: I bought 4 at 2.89$ each. All worked upon arrival. Only using 2 ATM. I installed one inside the front of the my case, blowing air in. While I have the another installed in the back, blowing air out. I have them set to 70% @ 2400RPMs. I can feel the air coming threw very nicely. I can place a piece of notebook paper in front of the In-take Fan (3 i.n.) and it'll be sucked up. My CPU and GPU temps went down by 8c I use Software called "SpeedFan" to Set my fan speeds.

Pros: Works (Camera Part) Runs @ 640/480 30FPS Picture is viewable and clear enough to make people out. (no pixels) Easy to attach to different surfaces.

Cons: It does lag a-little bit, so don't move too fast. Mic is useless and can cause the device to fail* (Does not work)

Overall Review: I bought this on Cyber Monday for 10$, no complaints here. Make sure you DO NOT use the MIC on the camera. Use a Headset or Stand alone mic. This is Web Cam is only really worth 10-20$

Pros: Offer's the 450w power as advertised. 3 Months in use and it still works.

Cons: 6-Pin PCEx16 Power Connector is too small (Fit's Loose in the video card) It'll cause random power shut downs. (Has yet to cause any damage to the computer.)

Overall Review: I'm using it as a temp PSU to test it out for another build. If the computer becomes bumped or any movement happens inside the case, it'll lose all power and make a LOUD Noise (Same sound for No power to the Video Card) Sure enough I check the PCe-6pin Power Connecter and it's lose (It is too small to fit snugly) causing it to come lose upon any movement (even air flow) causing a shut down of the computer. My Antec Green 500Watt PSU (Now back in) It's 6-Pin connector fits nicely. Video Card I'm using is a MSI N630GT-MD4GD3 GeForce GT 630 4GB 128-bit I've tested other video cards with the COOLER MASTER GX 450W and they where all lose with it. Guess I'll keep this PSU for a backup. As it's well pass its RMA date.
