I wish people that did reviews would actually understand how heatpipes work. If they did, they would know to install it the other way so that the pipes come out the bottom of the base and curve upwards into the fins. Heatpipes rely on gravity to return the cooled/condensed liquid from the fins back to the base. Some heatpipes have wicks or grooves inside to aid their performance against gravity, but they still work better when installed the right direction. They probably would have seen a couple degrees improvement in the review if they installed it the other way around.
