ID-Cooling IS-40-XT vs. IS-47-XT - Which is better? 

They had to do that in order to make it AM5 compatible.

​@@geekdk i want to buy 40-xt for my 12400f is it enough? Is there any performance difference compared to the Intel stock cooler? tbh dont really like 92mm fan, rn im still thinking to buy 40-xt or is-50x v3

12400 is already pretty chill CPU with TDP of about 80w at full load. I don't believe 40-XT will give you an edge. It will be quieter, however. 50X would be certainly better.

They are the same cooler.

@@geekdk i read the TDP of XT only 95 while XV3 is 100w sir. Thats why i confuse

@@syarifairlangga4608 In this video ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0123f3h1wVo.html ) , I compare 40X and 40XT briefly. They look the same. They cut a bit of fins in XT to make a room for AM5 mounting.

@@geekdk owh i see, so thats why the old version is better i think for intel
