AMD Radeon R9 M395X 4096 MB
27" imac not small, and I'll never be cleaning the fans etc, Idk how to do that on an imac and dont want to risk damage, i am confident on how to do it on macbooks with a removable bottom shell, thats it
this imac is refurbished,from Apple, i got in january- so there is not 2 yrs + of dust inside.
problem is, like i said a few x, ALL other usages i get ZERO graphics or fan issues, its only x-plane 11 with smp installed, remove smp and all is well-
fans rev high on initial load, then die down
i am stumped
