I enjoyed reading the review - you've looked at some things other reviews miss, and it doesn't read like an advert.
However because you had gone in to so much depth I had my fingers crossed you would go into depth on the Fan Xpert software. What frustrates me with my Crosshair IV Formula is the software is great for the CPU fan, and allows me to control all of the chassis fans at once, but it doesn't offer any control over the other fans.. and BIOS isn't any better.
I'd dearly like reviews of the new 9 series chipsets to mention in detail how much control over fan speeds exists. I must not be the only person who wants a nice quiet PC when I'm not gaming.
Ah, yes, Fan Xpert. Well, it's just the same here, with the CASE_FAN headers all controlled together, and the CPU separate. The PWR fan is not adjustable at all.
I did make note of what fan options were available in the screenshots of my next ASUS M5A-series board, which will be coming up shortly. However, I can simply say that the fan control offered is just the same.
I thought that the Crosshair series allowed for individual fan control in BIOS? I have not run one since the CrossHair III though, so I might not be fully up to date on that.
Also, I do beleive the Sabertooth boards offer individual fan control for each header, as part of the "Thermal Radar" stuff, but I haven't received my sample of those two upper-end boards just yet. I do hope to take on both the Sabertooth and the Crosshair V boards in the upcoming weeks, so hopefully I'll have more info on your specific question in the near future.
Thanks for the feedback, too...
