    How does this work out? Does it cool it well enough when gaming and doing other tasks for extended periods. The acer 3820tg has two fans cooling both, seperate from each other of course. What other good laptops use one fan to cool both gpu and cpu?

    I think Macbook Pros also have dual fans. The bottom of the y460 allows the laptop to "breath" if you will. Most people report temps in the 80C range, which is well below the shut off of 105C.

    As someone said in another fourm; Trust the engineers who make the laptop. Adding another fan means nothing if the design of the cooling system is awful.

    As far as I know, not all that many laptops have two heatsinks with fans for each of them. I would assuming gaming laptops would, but they are huge compared to these types of laptops.

    I just figured all laptops or most have duel fans. My alienware did. I guess I was just surprised. Yes its definitely correct in saying if the design is no good then it doesn't matter how many fans you have. In this teardown of the Y460 without the dedicated video card it shows the fan cooling the chipset along with the cpu. What cools the chipset then in the ati version?

    ^No, most notebook only have one fans ...
    Dual fan notebook in non-gaming notebook is rare, like Acer 3820TG, HP Envy 14, MBP 15/17...

    I just gave my newly-bought Y460 a spin in BFBC2 tonight while monitoring temps, the CPU reached 80 at maximum and the GPU never topped 75. It seems to me that the cooling is "good enough," at least. My old Core 2 Duo laptop would top out at 85+ before I discovered undervolting.
