As you all know we own a computer store, so when at first a customer asked me about a year ago for notebook cooler – i had told him that we didn’t have any nor had i heard of any. He definitely looked like he had joint pain when i said that – i mean for sure he must have had done his research and the spouse corrected me immediately. Now that I am using the notebook permanently – i too know that i need a notebook cooler now. As the notebook gets older and even after blowing dust out – it still doesn’t want to cool down – then you know you need one. A notebook cooler cost like $35 – and this is a Thermaltake brand with a 23cm fan in it. It is supposed to be quiet – and improves the overall heat dissipation. It is very light weight.. and supports from 10 – 17″ notebook. So if your notebook is overheating – get a notebook cooler quickly before it fries anything up.
