The product I needed urgently. My toshiba dusted with a fan yet begun to seriously overheat and suddenly turn off after half an hour of games (hard disks do not like it on my old laptop, I grilled a due the same problem). So I opted for this model after extensive research. Its size is perfect for my 17 inch (length and depth). Fans perform their function well. The temperature drop is flagrant and noise generated by them is reasonable. More untimely cuts even after 3 hours of play in 3D. 2 The product benefits: option to choose between the large, small or ventilos all ventilos same time. The second USB socket on the back. Conclusion: satisfied with the purchase, I only hope that it will be reliable.
