    Just wondering what speed you guys are running your fans?
    I am using:

    900 Exhaust
    800 CPU
    800 hard drive

    Trying to keep the owc ram cool temps around 77C when working hard.
    still whisper quiet though.

    CPU: 600
    PCIe/HDD: 700
    Rear: 1200
    Power Supply: 600

    I have to double the rear fan speeds to keep the Netlist RAM modules (or at least the one in the A2 slot) below 170F, above which they tend to throw ECC errors. 1200RPM is just below my audible threshold, so at these settings my Mac is still silent.

    Exhaust: 700rpm
    CPU: 600rpm
    Power Supply: 600rpm
    Hard Drive: 500rpm

    Seems to keep the temps down enough during normal usage.

    Perhaps by stating how much rams you got can better explain the reason for using the particular fan speed etc. More rams = more heat etc, hence higher fan rpm.

    Ram

    I have 8 1gig modules
    I emailed owc tech and they said that 77 is within the normal range only worry if they reach 87C and over.

    I have 4X1GB Netlist modules in the front, and 4X512MB Apple modules in the rear.

    That's funny because I emailed OWC tech and they said this about their OWC Apple Qualified 2GB RAM modules for the 2006 Mac Pro.
