If you are a hardcore gamer or play too much games then you should get an a radiator to your CPU. This is because in gaming your CPU is working continuously and is under heavy load which increases its temperature rapidly. The rise in temperature can reduce the performance and the lifespan of your CPU. So if your stock radiator is not working properly or is not able to keep your processor temperature in check then you can buy a good radiator for your CPU to keep the temperature in control. These are the traditionally designed radiators that have normal aluminum heatsink and a fan on the top.
