Check your BIOS version to see if it's current.
Your MSI B450 tomahawk works with this CPU on your desk, but the BIOS version listed is 72C02v1I. The build number shows 1.I, which matches your requirement. The extra zero might be a minor formatting change—just confirm the BIOS file name ends with "1i" for your motherboard. Your PC has been running for 30 minutes; it’s safe to proceed with the replacement once the cooling cycle completes.
Turn it off and begin working. If you recently completed intense benchmarks or games, the GPU/CPU cooler may feel warm to the touch—let it rest for a while. Regarding your second point: Updating to the same BIOS version is perfectly okay. Feel free to ask more questions or seek help—I'm here to assist.
