RPCS3 has an option (if your CPU supports it). Counterintuitive effect : AVX-512 usually runs hotter, but on RPCS3, it completes SPU operations in fewer cycles → lower sustained heat. Test it: my 11700K dropped from 92°C to 81°C with AVX-512 + an undervolt.
Some games have “fake” SPU loads that just burn cycles: rpcs3 high cpu temp
(Biggest impact)
Result : Base clock only (e.g., 3.6 GHz instead of 5.0 GHz). Many games still run full speed (RPCS3 often gets memory-limited before clock-limited) but temps drop 20°C. RPCS3 has an option (if your CPU supports it)
Here’s a concise, interesting guide to tackling (the PS3 emulator). Unlike typical PC gaming, RPCS3 is heavily dependent on SPU emulation , which can push CPUs to their limits—often running hotter than even Prime95. Some games have “fake” SPU loads that just
