    Default what fan activity should I expect to see under CPUID?

    Recently purchased this build:

    Asus P8Z68-V Pro Motherboard
    Intel Core i7 2600K QUAD CORE 3.4GHz 95W CPU
    2 x Kingston DDR3-1333 4096MB Ram
    EVGA GeForce GTX 560 Ti 1024MB Video Card
    Western Digital Caviar Black 1.0TB SATA 6 Gb/s Hard Drive
    Asus 24x DVD-RW Lightscribe SATA CD / DVD Rom
    Antec P183 V3 (Gunmetal Finish) Case
    Antec CP-850 850W Power Supply
    Gelid Tranquillo Rev2 CPU Cooling
    Case Fans Upgrade Kit (quiet)
    Antec P183 General Quiet Modification Package
    AcoustiPack Acoustic Composite Sheet Package
    Scythe Quiet Drive for 3.5 inch Internal HDD
    Windows 7 Professional 64-bit OEM SP1

    when monitoring it with CPUID 1.180 I only see two lines for fan activity; one for the CPU fan and one for the video card fan.

    In contrast, from a review of the SPCR Serenity:

    there are entries for sysfanin, cpufan, auxfanin0/1/2 (dups?)

    Should I expect to see (running at idle) entries for sysfanin and/or auxfan?

    Hmm, that is an interesting screenshot from AnandTech. I would expect to see info on the CPU fan, and video card if using an actively-cooled model, but the rest of the fans we install are not wired to the motherboard... so it should have no way to 'see' them and what speed they are running at. The fact that all of the extra fan listings on that screenshot show the exact same RPM also makes me wonder - and I really think that must have just been a bug with the software.

    What we do, so you are aware, is wire the chassis fans directly to the power supply. That way we can control how fast they are running via voltage... and I believe we put the fans in Serenity style systems at either 5 or 7 volts (instead of the normal 12V). That keeps them good and quiet, but there is no motherboard connection in there so it has no way to monitor speeds. There is really nothing to monitor for, though, besides possibly a fan failure.

    In short, your lack of fan speed entries is exactly what I would expect - the article is what is odd. It may have been a software bug on their end, or maybe just a difference in how the BIOS on the different boards works... but nothing you need to worry about
