Lenovo Y480 user here

Hello there.I am looking to buy a notebook cooler pad for my laptop,usually use it for surfing and minor gaming.Can anyone recommend me any good cooler pad for Y480.I am actually interested with Cooler Master Notepal U3 and X3 model but what bothers me is that which of these two can give better cooling effect to the laptop temperature.There are 3 airflow vents underneath the laptop,2 of it at the bottom part while 1 at the top left.No vents at the middle actually.So I thought U3 is a better choice as I can put those 3 fans exactly underneath the airflow vents .Or do you think X3 will give a better cooling effect as the fan is bigger.Anyone here who have used these kind of coolers before feel free to share your experience with it.If you have better cooler pad for recommendation.Do tell

Hello there guys. I am using Lenovo IdeaPad Y480. So let me get directly into the topic. It all started few days back when i booted the laptop from hibernation. The problem I am facing now is that there is sort of a vertical line at the bottom part of the screen, it changes colours sometime from red to green. Another problem is the graphic card which is Nvidia 650M is not detected anymore. It is only read as Standard VGA Adaptor in the device manager other than the Intel HD Onboard graphics. I tried uninstalling the Nvidia drivers and reinstalling it back but to no avail. The installation will fail and it is as if there is no more working graphic card in the laptop unless the onboard ones. So am i dealing with a faulty graphic card guys? I tried booting the laptop in other screen and there was no vertical line on there, only on the laptop screen. Help me to clarify this problem guys. If it is a graphic card problem. What is the best I can do to solve it?Thanks

Thanks for your replies guys. I guess I have to send my laptop for warranty claim then, hope they will replace the parts with no hassle. It looks like there are a lot of users reporting GPU problem too. Anybody who had sent their laptop for warranty claim to Lenovo Service Centers mind to share their experiences? :-)
