I think I know how to get to the 2 graphics module fans but is there a third one for the CPU? If so, how do I access and clean it?
There are only 2 fans in expansion bay shell/ GPU shell. Please pay attention to following places, because there is a lot of dust which blocks airflow
No. the Framework Sixteen use the graphics module fans to cool the CPU as well.
Depend on your expansion bay config. You might need to partially disassemble your GPU to get to the heatsink fins on the GPU module.
I find the 16 is really easy to clean by simply removing the expansion shell and then blasting air into the vents. You dust bunnies will come right out.
