Need a slim cooler (only 1 inch high) for a 15.6 inch laptop. I wanted variable speed. 6 fans required. I have all of these plus a switch that wasn't listed in the description. The manufacturer also indicated in correspondence that there is a one-year warranty, which was not specified. The noise level is 45db which is higher than advertised but acceptable which is why I gave the noise level 3 stars. Cooling is excellent and really brings the computer's temperature down to the touch. I am happy with my purchase and would buy again. This score is straight out of the box. Hopefully this holds together, I couldn't find any review that said the fan failed.
