3 out of 5 eggsDoes the job

Pros: Big fan, variable fan speed control, optional DC in (sold separately),

Cons: The fan isn't as quiet as I had hoped. Has a ticking sound when running on any speed. Not normally audible over my headsetsand playing a game which is when I have the fan on. The USB hub is only v2.0 (but this is in the specs so no real points off for that). The worst part, but not a killer, is that the plastic molding around the 2 USB plugs (the ones that plug into your laptop, one for USB data, one for extra power) are rather thick horizontally. I had to trim the excess plastic to allow the two to be plugged in side by side.

5 out of 5 eggsGood Cooler, Quiet Operation

Pros: Moves air, keeping temps down
Large fan keeps noise level acceptable - no whiny 80mms!

Cons: Minor considerations: Fan exhausts at bottom, but heated air is less dense than cold (lol physics); What does that button on the side actually do beside change the light from blue to red? See Other Thoughts for potentially forthcoming modding

Other Thoughts: The fan is good at moving air, though I am considering disassembling it and reversing the fan's orientation to blow air upward (and into the laptop's intake) rather than downward as it currently does - I doubt that this will be too difficult as the screws are easy enough to find. Hopefully that change will help improve its cooling further (plus, cool hands - neat?!) though your mileage may vary depending on how your laptop exhausts. Maybe if I get really bored I'll mod it into the bottom of the laptop. :D
