llano V10 Gaming Laptop Cooler, RGB Laptop Cooling Pad Stand with Powerful 4.72 Inch External Turbo Cooling Fan, Fast Cooling Computer 13-17.3in, Button Control, 3 Adjustable Stand, 4-Port USB (White)

I was getting -10C In heat reduction when turning the fan on 500RPM, and I wasn't doing any heavy computing, just normal work, for example browsing the internet through chrome, typing on word ect. Under heavy load like rendering on premier and designing on Photoshop and the other previous stuff mentioned, I turned the fan to 2000RPM and I was getting -15 to -20C in heat reduction. After 2500RPM+, it starts to sound like a mini jet engine. It's a very useful piece of tech not only for the cooling part but also cause it elevates the laptop. Buy it with your eyes closed. The fan is metal and the pad is ABS plastic PS. my laptop size is 16 inches and it is a good, snug fit

Managed to reduce my laptop temp by 15 - 18 degrees which is a very big help esp gaming on overdrive mode and with long gaming session as it will extend the lifespan of the laptop components. overall a very worthy purchase. thanks!

Excellent
