Just want to add some fun fact here as a small caution to some posts here. Idle is not constant state on PS3. You can't compare xmb idle on different setups. Let me explain that. XMB wave is not so lite for Cell/RSX. Important note: All data is my old measurements, so is only one person test. Tests was made in early 2016 or late 2015 in 19c room, with fan set to 32% on CECH-210X. All temp are measured using webman lite (current for that time, can't recall version) with disabled all possible functions, after 30 minutes of idling in XMB (30 minutes for every possibility, not at once). XMB with Original wave mode - is most heavy non-modded option. My temps in that mode was 59c (fun fact 2: You know that you can move that small stars in xmb by shaking controller?) XMB with Classic wave mode - is heavy, almost unnoticeable difference on temps. 58-59c. XMB with Custom background image - Lightest available option, PS3 don't need to draw wave so my temps was 54-56c XMB with custom wave? - 57 to even 62c in some cases. Lightest was just "one liners", most heavy was waves in "Lighting" shapes. Multiman in MMOS - 54c (!) Like you can see, idle is not true idle on PS3. Problem is probably in solutions made by $ony in XMB. Instead of made some static graphics they decided to use parameters to real time draw wave. Not best idea, but also not worst i ever seen. PS. Some solder components/pastes/bga's are oxidating even in 60c, until we don't know true ingredients of bga used by $ony after RoHS directive. We can't truly say that some temperature is safe or not.
