I've always wondered how much of the market out there is a response to real need or provides a genuine benefit and how much is just an attempt to part you from your hard earned cash.
Notebook coolers are a JOKE... Yeah I know, "tell us what you really think".
90% of the cooling problems I've seen on notebooks are "user induced"... using the things on a bed or couch where the vents are blocked, holding them on your lap, where the fan intake is blocked... etc. One customer even taped over the hot air exhaust complaining it bothered his hand while "mousing"... then tried warranty claims when it cooked the CPU and finally came to me to fix it.
If you want a little extra cooling for your notebook:
1) use it sensibly... on hard surfaces, keeping the airflow vents clear
2) Keep it clean... it takes only a few seconds to brush the dust out of the vents every so often.
3) if you want extra cooling... put a ruler under the back legs.
There seems little or no reason to spend $20 to $150 for something you can fix with a bit of simple common sense.
