my GPU is AMD Radeon HD 5450 and I don't intend to buy a new GPU even if it would be a better choice but I would like to find out what kind of fan or heatsink do I need to install to it that it might cool it down as it reaches high temperatures even when idle it only has one little fan and since it is an old GPU I'm sure it wont be easy anything to fit so I'm hoping someone here might know.
