    I installed 2 new hard drives and now my fans are going crazy. Does anyone know where i can get some stick on/glue on/clamp on fins that would fit in a mac pro? I've seen a bunch that run parallel to the length of the drive but not perpendicular.

    I would check the hard drives first or you mac pro for problems there is no reason why you fans should go crazy cause you added 2 hard drives.

    How will adding heatsinks to your hard drives reduce your fan speed?

    I guess because with heatsink fins the fans wont need to run as fast to cool them down. The the heat isnt just on the hard drive block itself and spread throughout the fins.

    this makes sense

    compare to a pc cpu heatsink and fan, I have short heatsinks on cpus and the fans scream to try and keep the temps down. On the mac pro you can see the massive heatsink + fins and the fan (admittedly is rather large) runs slow and more importantly the cpu temps are a lot lower.

    The hard drives temps go up thereby making the fan speed increase to compensate. The more the computer is able to radiate of heat off of the parts themselves the internal temperatures will go down and the fans won't have to spin as fast to keep the same temp.

    Yea anything to make the computer cooler will help. And hard drive fins do help. Unfortunately i still can't find any that fit.

    This is kinda off topic but has anyone taken their computer apart and replaced all their thermal paste with the silver stuff?

    it seems weird that just adding a couple drives would make your fans run so much more....

    when i added 2 to mine i didn't notice any difference at all....

    Just a thought: I would take out one of the drives, and see if the fans still run fast. Then swap with the other drive. You may just have one bad drive that's overheating.

    If fans run normally no matter which of the new drives is installed, try experimenting with which bays they're in.

    :cool:

    I have a new Mac Pro with (4) WD Caviar 7,200 RPM RE2 750-GB drives installed (also 16GB OWC RAM). Computer is virtually silent (and I live alone in a dead quiet room where you can hear a pin drop).

    I have 3 HDs in my macpro 2 x 500GBs and the standard 320GB drive and my fan revs have not increased at all from when it had only the stock 320.

    Actually I did notice that my fans increased speed from 600rpm to 800rpm after I populated the other 3 drive bays.

    Maybe people can comment on their hdd fan speed in relation to how many drives they have?

    does allowing the hard drives to sleep slow things down significantly? With 4 drives installed, 1 or 2 of which aren't accessed very often it would be nice to let those sleep, while the others remain active.

    Hard drive fins will NOT slow system fans. the fans run based on box temp, not based on HD temp.

    Basically if you put heat generating devices (i.e. more ram, more HDs) then you have more heat to exhaust from the box, but the fins do not reduce the amount of heat.

    What they will do is more efficiently remove heat from the drives, making the DRIVES cooler, but that heat is still going into the case and therefore the fans will not run any slower.

    I personally didn't have any speed increase in my mac pro and I've got 4 drives stuffed in there. Sounds like something else is going on on your machine.

    Maybe i'm getting that reverberation that a lot of people have been getting. I'll go find something to stuff in the space today.

    fins will not reduce the temp of the hard drive bays...they are enclosed!

    waste of money/time.

    you seem to have a problem somewhere in your setup. 4 10K drives wont cause the fan speed to increase THAT much...

    just out of interest can you post your fan speeds/hdd temps?

    How do i do that with temperature monitor? I just reset the SMC and the P-RAM. Let me see if it does it again. The only other thing i have changed is i installed Vista SP1 with efi booting.
