I actually recommend buying a 13900k. The 14900k only runs at the performance of a 13900k in cinebench etc with a noctua nhd15 due to temp lock max 90 degrees and heat problems, I would recommend 360 or even 420 aio water cooling or as I said a cooler processor. LG

If you don't want a water cooling system, then this fan CPU cooler NH-U14S. Important, please check the dimensions to see if it fits with the ATX housing.
The CPU can be used 100% with this fan without restriction. Temperatures between 75 - 90C.
