It seems your MX-4 didn't match what you expected for your i5-11400.

It's probably because they can put cheap stuff in the package, charge the "premium" price for it. The packaging probably costs them more than anything. It's a serious problem every where actually. If you aren't careful to buy from authorized vendors you are pretty likely to end up with a counterfeit (in any country these days). I know I check my Thermal Grizzly is another that gets counterfeited commonly too.
You asked in a way that needs clarification. Could you rephrase your question?
