XtremeComputing posted a review on the Thermaltake T1000 Laptop cooler

Not only does this heat make using my laptop for long periods of time uncomfortable, it can also damage and shorten the life of computer components. So it is in my (and probably your) best interest to keep your laptop as cool as possible. Laptops don't generally have any way to control the fan speed on its cooling fan(s) so what other way of keeping the laptop cool is there? Well that is where things like Thermaltake's range of laptop coolers come in handy.
