This Noctua NH-L9a-AM4 cooler is designed to work smoothly with your AMD Ryzen 7 5800X and other similar processors. It should function well without issues, even with a low-profile SG05 case. The placement of the PSU on one side helps balance cooling performance. Many builders prefer this setup because it keeps the system compact while maintaining good airflow.
It could be a push, what space do you have available? I have some ideas that might fit better and save money, but they depend on clearance. For example, the APX90-X53 would work well with a larger heatsink, four heatpipes, and just 53mm height—your case is only 82mm clear. Alternatively, you could opt for a 120mm low-profile model. The APX120-X67 stands at 67mm and includes six heatpipes.
It's not working well. The 5800X heats up a lot compared to other Ryzen 8 cores, making a small LGA 1151 cooler difficult. Plus, it’ll compete for airflow with the PSU. I suggest either changing the case or replacing the front PSU with something better, as other users have done this to improve cooling.
I have an L9i cooling more than the 120W this needs but with good forced case airflow. That's an old case designed for low power HTPCs and such...
Other options with lower profiles are available that could work better than the Noctua ones discussed here. Still, using something like that on a 5800x will be challenging, particularly if you're not familiar with adjusting Curve Optimizer undervolting. I've had a 5800x since installation, still running under a 360 AIO and undervolted.
Noctua claims functionality is possible yet offers minimal turbo potential.
The situation involves a significant fan placement on the SG05 model. It's worth checking if a 5600 CPU is suitable. The lower panel doesn't have ventilation, so I should stay cautious to avoid damage.
The CPU won't break down, though the thermal coolers listed earlier will clearly boost performance without costing much more.
