Also try to figure a way to rule out that your copies of homebrew apps are not corrupt in some way or perhaps need to be reinstalled (like after a firmware install).
Does ANY homebrew work perfectly fine and close perfectly fine? Or is it just irisman and psninja?
Your temperatures are great so that leaves software/firmware related corruption.
I figured it out, my ps3 was full of sh*t had like 9 movies installed etc deleted them
