So interestingly enough, I found this test by HWcooling. It actually tests the 12400 with the L9i. By the looks of the results, If i am understanding them correctly. It seems to cool the 12400 good enough? 77c in cinebench23 @ No PL. I was a bit confused when it started getting into the PL stuff though. What do you make of the results, despite noctua saying the cooler is not compatible? Thanks again for all the advice.
Edit- I actually see part of the issue. It says mechanically incompatible because the actual L9i is a couple below that called the L9i-17xx (For the 1700 chips) So i guess it's compatible, but it seems to have a low score for boosting.
Results: Maximum performanceVery low profile, high cooling performance and Intel LGA 1700 support. These are demanding requirements that Noctua NH-L9i-17xx meets as one of the few coolers (maybe the only one?). The first two requirements could probably be argued about in others, but in the end...

Dang, I missed that.
Even then, it's still not great, and Cinebench doesn't accurately represent the system under a gaming load either, as they can be worse than Cinebench.
Downdraft coolers don't do as well as they could in cases that have no ventilation over them, in the side panel they face.
In ATX cases, they do ok, until the gpu is active; in most PCs today, those gpu's use open air coolers dumping their waste heat inside the PC. The gpu is the closest ventilation to the downdrafts - not the front fans, and not the fans above or at the rear.
ITX cases have some variance, including the above scenario: a vertical gpu, gpu AIO or custom loop, glass or other solid panel may be in front of the cooler.

Going by this old thread over on overclock.net, changing the fan position may actually be better for it than what the default does.
[Some of the images on there are indeed broken from the last site platform change, and I suppose the author never bothered to fix the broken ones.]
Downflow / Pancake Cooler Fan Orientation for Better Cooling
"I've found more often than not, using the fan to pull air up from cooler give significantly lower temps than pushing air into cooler.
Reason is, pushing air in through cooler means hot air coming out toward motherboard turns out, hits RAM, GPU, I/O housings etc. turning up past cooler & fan and is sucked back into fan.
With fan pulling out of cooler, air flows over motherboard, up into cooler, fan and out side vents.
Even on open bench testing just turning the fan often lowers mobo and CPU temps by 5-8c."
