i keep my m14x cool with the CoolMaster CoolPal U2 that fits up to a 17inch laptop and can hold any laptop from 14" -17" for the price of 30-40$ on newegg.com it comes with 2 80mm fans.
I use Evga precision to keep track of my GPU temps while playing games its a free program can download it here-->http://www.evga.com/precision/ . It also allows you to overclock your GPU
i use FRAPS to manage my FPS while trying out different graphic settings for the "NEW-GEN" games of 2011 also helps me record game footage to upload to youtube after i edit it in Sony Vegas Pro.
I do no OverClock my laptop its all the stock settings it came with the only thing ive done was upgrade the 4GB ram to 8GB Ram @ 1600mhz for better gaming.
