if you are going to be using it for long periods of gaming or cpu intensive tasks, then I certainly would.
Also if you like to sit on the sofa with it on ya knee, i would, to ensure you don't block the intakes. ( I burnt out an old lappy due to being sat on the sofa. )
100% yes use a laptop cooler! It can only do your laptop good and at the end of the day it could give your laptop a much longer life time. A laptop that costs £1000 that lasts 3 years is £333 a year, laptop that lasts 4 years is £250 a year. What's £30 for a cooler?
Personally I'd go for the 3000 (and i'm thinking about getting one myself) since it will push so much more air and it should line up whatever laptop and vent placement you are using at the time.
I know youre not supposed to game on a laptop on your lap (ie on the sofa) but i often do when just chilling out with mates/family so my question would be how would the two suggested coolers work/feel when on your lap?
I suppose looks are subjective, all I can say is that I can vouch for the NC2000 - its beautifully made and fits the laptop chassis perfectly; as if it were made for the machine.
With regards to how it feels on one's lap, not great to be honest; when I'm sat on the sofa and fancy a game or two, I'll pop it on the cooler and a lap mat - thus bringing it to eye-level and ensuring comfort.
I've heard good things about the Logitech Lapdesk N700... Can any verify whether it's actually worth the extra money and whether it's any good for a 17" laptop?
Unless you are smothing your vents in a room is over 30 degrees C in a country with horrendously dry air, your laptop will not overheat. If it does, it is obviously faulty.
If you would like to buy one regardless, the Zalman cooler mentioned earlier in this thread is excellent
One of the reasons I was considering one is that the vortex is reported to produce a fair bit of noise with the fans at full wack (eg when gaming) and a cooler can bring the overall noise level down by taking some of the load off the internal fans. I'm waiting until I actually have mine before deciding for myself if the noise is too intrusive or not.
