Savior of the notebook

My Acer folding computer crashed just when I was surfing on Spiegel Online (too much Werbefilmchen?). And I was about to buy me a new one, after several fan cleaning tests brought no solution. Then I gave this cooler a chance - and I'm thrilled. Even in these summer temperatures I have not had a crash more. The notebook is warm but not too hot. The noise level is a bit higher than before. If it's cooler, then makes itself felt that the notebook is on a grid, even if the cooler remains off. For a short or little compute-intensive applications as that.
The only drawback: The loop-through USB interface is a bottleneck. Lack of free USB ports, I tried a backup over on an external hard drive. I had to stop, it would have taken days! Dear, I then made a different USB port for free.
