Hardware verification (optional — lets us mark your model "Tested" right away)

• Silent noticeably lowers CPU package power and/or fan noise vs Balanced (seen in HWiNFO64, or clearly quieter/cooler by ear).
• Extreme unlocks full power / the fans ramp up as expected.
• Switching profiles in the app is stable — no crash, black screen, or stuck fans, and the app's profile matches what I selected.

Confirmation

• I understand this is experimental and EC writes are at my own risk.
• I'm willing to test a proposed recipe on my machine and report back.

@Harsh3456D This capture is exactly what we needed - thank you. The scenarios switched cleanly this time: 0xD2 goes C2/C1/C4 as shipped, 0xEB toggles 00/0F, and your #43 test curve sits at exactly 0x72/0x8A, so the fan-curve addresses are hardware-verified as well.

Your model is now Tested with a verified fan curve, credited to you. Ships in v1.24.0 (very soon). Thanks for the persistence across #12/#42/#43/#44.

One small follow-up, purely for our records: which MSI Center version are you on (Settings → About)? In your dumps the Silent step reads the same as the Super Battery step, and knowing the version would tell us whether newer MSI Center builds changed the scenario lineup on this generation. No action needed beyond that - everything required for Tested status is already confirmed.

The version i m using of msi center right now is :
2.0.71.0
