Great help, but I do have one question. My Noctua NF-S12A fans are rated w/ min. rotational speed @ 300 RPM +/- 20%. So I set lower noncritical to 240 RPM, which the ipmi on my SMC X11SSH-F-O motherboard set down to 200 RPM. Following your instructions, I set *lc* to 140 and *lnr* to 40, and the motherboard reset them to 100 & 0 RPM respectively. Is this right, or should I have set them to 200 & 100?
WOW! Awesomely thorough guide - I wish I followed this from the start and didn't waste several evenings running into dead ends wiping, flashing, re-flashing, re-wiping, etc... Thank you for putting this together and explaining the background and reasoning for having to follow the steps so specifically. My Dell H310 is now a LSI 9211-8i P20 in IT mode finally! (I suppose I have to finally start my "real" project now, lol)
