so you never got to your heat sink?? As for the ps5, it should be pretty cool, but we don't know how extreme the apu gets since its overclocked all the time, so all that cooling is necessary. But the chief engineer did say in an interview, that generally the ps5 runs quieter than ps4. Whether or not the fan spikes during high iintensive games, we will find out. My room is well ventialted, ps4 stays quiet, also have an ac to keep the room cool during summer.
I went over everything. Heatsink itself didn't have any dust on it other than a few particles. Same with the fan. The plastic housing the heatsink sits in had a super thin layer of dust which I could just wipe off. The entire internals of the console were extremely clean, which wasn't a huge surprise as the house is kept quite clean.
My PS4 used to get loud and annoying after about an hour by constantly having the fan ramp up and down the longer I played. It sits in an entertainment cabinet, yet the front and back are open and there's plenty of room on the sides for it to breathe. All my consoles have sat in there and never had a problem with heat recirculation. I've got rubber feet under it to raise it off the base a little more than the stock feet as well for better cooling underneath. With the fan adjuster, the noise it makes, while louder when idling, is reasonable and extremely consistent. I can play for hours and the fan only ramps up one step over my 40% setting like once or twice, for maybe 10 seconds and that's it. It's much much better than the stock fan curve set up.
The PS5 APU isn't OC'd. It's designed to run at higher clocks, and those clocks are somewhat variable with fairly consistent power. The way the PS5 APU operates is like an advanced variation of how a typical PC CPU/APU operates. Along with that, only the most recent AMD laptops have SmartShift tech in them, which the PS5 happens to be using. It's also unlike with a PC, where if you decide to OC your CPU/APU, you really need to install a beefier cooler to handle the excess heat, plus to keep the noise down, not to mention higher end TIM is recommended. The PS5 cooling system is designed to handle the APU naturally running at higher clocks. It will never be pushing the clocks beyond what the cooling system can handle without becoming a concern.
It's pretty clear when you look at the launch PS4 size and it's cooling system vs the launch PS5 size and it's cooling system, SNY is making sure noise will not be a problem. A giant shell, with large heatsink, big fan, and highly efficient TIM, screams SNY is serious about cooling and noise for PS5.
