required cpu TDP vs cpu cooler TDP

[ale1h3]

hey guys i want to know can i use a cpu cooler that has higher tdp than actual required cpu tdp for example core i5-6400 requires 65w can i buy cpu air cooler that has 160w?if yes why if not why? also if u know a youtube video that talked about this topic pls link it down below i didnt find anything about thing like this.thanks!

yes ofcoure. It usually means that your cooler is sort of "overkill" and it will cool it very well.

if you buy cooler under 65 tdp your cpu will likely overheat.

Both of those values are arbitrary and cannot be directly compared because they are calculated in massively different ways. Ignore them and look at review and extrapolate data from those.

TDP - in the simplest terms - is how much heat a CPU will produce.

A cooler rated at a certain 'TDP', is basically just saying "I can cool a CPU, if it's this TDP or lower".

 

So yes, you can use a higher rated TDP cooler on a lower rated TDP CPU. No issues.

Whether that is needed? Likely not.

Problem with using just TDP is that its not standardized. So number that CPU manufacturer gives and number that cooler manufacturer gives aren't particularly accurate. In your situation we are talking about some cooler that most likely is way overkill for locked CPU. Just about every aftermarket cooler would be in terms of cooling performance. But there are also cases where cooler which doesn't match CPUs TDP can actually cool it fairly well.

The values supplied by the manufacturer can vary wildly and be oftentimes misleading.
Only use the TDP given by the manufacturer, such as Be Quiet! or EVGA as a baseline to compare their own cooling products. 
Different testing methodologies and environments can often sway the numbers in the marketing team's favour. An i5 6400 is fine with a cooler like the Gammax GT/400.
