Summary: It truly is a BIG cooling stand, really big. Its wide to accomodate the 19"it promises but the wedge shape of it is really high which is great if you are thinking you will have your laptop in a more static place when you are using it but quite bulky if you are putting it on your lap.
Pros: Cools it down. Large size. 4 USB's. Solid.
Cons: Description fails to mention external power needed. Large size.
Summary: My only problem with it is portability. Since you have to have it plugged in, you cant take it anywhere. It does get a bit noisy but I dont really care about that because at full speed it drops my main temp by 30C degrees. Which is awesome, every other laptop cooler I have used has only dropped it 2C-9C degrees. Light are cool but I have no need for them. Its also really big, a lot bigger than I anticipated. No big deal.
Pros: Significant cooling improvement over any other cooler I have used.
Cons: No usb power option, you have to plug it in.
Summary: It is a lot bigger than it looks, not so big it is out of place. It is a little noisy as full speed but it doesnt bother me. My laptop is pretty powerful and would reach temperatures of 90+ degrees Celsius. Even doing the most it can do it stays at about 50-60 degrees now which is still higher than I want it to be but at least it isnt hot to touch the top metal by the keyboard.
Pros: Good solid product. Alot of air output. Adjustable speed.
Cons: No usb power option, you have to plug it in. Fans dont move as much air as I like.
Summary: im running a dell xps i7 2820 turbo with 12 gig memory a 3gig nividia g-force 3d ready graphic card and 2x640 gig hd. my laptop runs extremely hot and i run it hard gaming from bf3 to cod to every day use...so far the fan runs and works great...the only thing i dont like about this cool master fan is the fact to turn it off i have to unplug it and re-plug it...if it had a on/off button this would be in my opinion the top dog for keeping your laptop cool...
Pros: fans run great
Cons: theres no on/off switch to turn the fan off. in order to turn off need to unplug the ac adapter.
Summary: Not to dwell upon the one negative, but the day after we got it I accidentally grabbed the cooler the wrong way. In doing so, I broke the adapter that connected the laptop to the USB by pushing it inside, breaking the little soldered joints. While I may not use the colored lights on bottom, they are nice and work very well.
Pros: Plenty of power for my 17" laptop. The motor runs very quietly.
Cons: The plugin adapter for the USBs broke very soon after we got the cooler.
