Well I have been searching for a coolpad for my laptop for over a week, but can't decide as most of them just comes with USB powered and as a USB hub. What I am looking for is something that is externally powered and also work as a docking stations or port replicator.
Few of them that gives me some additional USB ports are:
Well i dont use one for mine even though i have one haha. Infact i just wanna throw mine away it also is powered by a usb port but i just hate it because when i use it, makes my laptop feel weird like more higher. Infact i bought it off ebay for like $12.00 which was a killer deal it has like 2 fans and a off and off switch came with free shipping so check out ebay also wouldnt hurt.
I bought a Targus about 12 days ago. It crapped out on me a few days ago. I haven't had the chance to return it yet =/
When it worked, it brought my temp down about 1-2 degrees.. Not noticable enough for me to spend $25 that's for sure. I recommend installing larger rubber pads on the bottom of your notebook, as well as adjust some Windows/graphical settings, and maybe up your fan speed. That is what worked for me.
