The VIP722 that I flipped around the laptop cooler has not changed temp yet. Still has an average of 116.
When I first set up my cooler, it seemed like it took a couple weeks to see a difference in temps. I think it has to do with the updates the receiver gets from time to time.
I just ran across another item that I'm going to try:
Amazon.com: Thermaltake Mobile Fan II External USB Cooling Fan - Us: Electronics
I bought 2 of them as I have a Playstation 3 that I want to try to cool down also. Seems to have good reviews on air flow and sound.
