I give up, I've searched google and tech websites all day and I can't find the answer. So now I turn to my fellow nerd brethren. Please forgive me if this sounds like a really stupid question.


TDP is typically defined as Thermal Design Power, the amount of power (heat) that a cooler must dissipate in order to keep a silicon chip within its operating temperatures. It is normally measured in Watts.

This is something I understand easily. The higher the TDP, the hotter the part gets.

What I don't understand is how to check if a certain fan is good enough to cool a certain TDP. Life would be much easier if fans were rated to cool upto a certain tdp wattage

Example: I have a computer who's CPU has a TDP of 80 Watts. I decide I want to upgrade to a much better cpu, but the new cpu has a TDP of 150 Watts.

How do I determine if my current fan is good enough to handle the upgrade? And if it isn't, how do I know if my replacement fan is good enough to dissipate the heat?
