Ryzen 9 5900X odd cooling behaviour, would like some input.

The 5900X is a PGA chip, so the pins are on the CPU not the socket. But what would a bend pin have to do with the temperature the chip is running at?

Sorry, I didn't look at which has the pins... no time. Bent pins can cause short circuits, heat and faults like BSOD... same with RAM.

None of which would make the CPU harder to cool.

The cooler is fine (not saying anything about the price/performance). Here would be an example of it working -> https://www.techpowerup.com/review/amd-ryzen-9-5900x/20.html

Even though they seemed to be a bit confused about which cooler they actually used ._.

 

A stock 5900X is super easy to cool. I can cool mine just fine with no fans on my cooler with a 180w PPT load from Linpack Xtreme.. and you are just trying to run yours at stock if I am not mistaken? Stock is like 142/90/140 and I run mine at 245/165/190. With a 10GB load in Linpack Xtreme, my 5900X runs at ~4550MHz for ~518-520 GFlops. In those conditions it is pushing the full 245/165/190. Under light loads a few cores hit 5150, a few hit 5000, and the rest hover in the 4950-4850 range.

 

Edit:

 

With my 5900X and FC140 I use Noctua NF-A14 3K iPPC in the center, and a T30 up front.

I would say the cooler is slightly underwheling for the cpu wattage

 

Noctua say 167watts is the cooling capacity of the U14s and tech powerup says the chip can pull between 181 - 350 watts on stress tests with no OC

I dont understand Noctuas NSPR rating but the cooler is one of their top performing ones so im probably wrong

NO 

 

That is not whattage, that is just some numbers (162 not 167) to compare to other noctua coolers higher = better cooling, lower worse cooler (like only usable for something no higher than a ryzen 7 5700x)

Wattage is a poor indicator of heat. Degrees C/watt would be much better.
