which ryzen 7 5000 series processor runs cooler at stock speed? I want to upgrade my AM4 setup over my GA AB-350 Gaming 3 mobo. I'm currently rocking a Ryzen 5 1600 paired with a Radeon RX 580 8GB and 2x16GB DDR4 RAM clocked at 2666mhz.

If you're looking for a cooler-running Ryzen 7 5000 series processor for your AM4 setup, the Ryzen 7 5700G would be a good choice. The 5700G is an APU that offers integrated graphics, which can help in scenarios that don't require a dedicated GPU. It has a thermal design power (TDP) of 65W, which is lower than other Ryzen 7 processors in the series that typically have a TDP of 105W. This lower TDP generally means it runs cooler, especially under stock settings. Another option to consider is the Ryzen 7 5800X, which has a higher TDP of 105W but still performs excellently. In terms of cooling capability, you'll need to have a good aftermarket cooler or ensure that your current cooling solution can handle the 5800X if you decide to go that route. Since you're currently using a GA AB-350 Gaming 3 motherboard, ensure it has the latest BIOS update to support the 5000 series CPUs before making your upgrade. With your existing setup, the Ryzen 7 5700G could provide a nice balance of performance and thermal efficiency.
