As the move towards smaller and lighter netbooks begins to gain in popularity, the dominance of older high heat-producing full size notebooks may eventually ebb over time. True, there will always be those users who want a larger screen size, or need the full performance of a high-end, multi core processor, and for as long as there are laptop computers making the tops of our thighs uncomfortably warm there will likely be coolers designed to combat it. Today I have a product for review from Thermaltake with the descriptive title of Massive23 CS, which makes use of a single, large 23cm cooling fan. How effective are laptop coolers at actually reducing operating temperatures though? Join me as I put the Massive23 CS through its paces.
