View Full Version : Removing front fan assembly on Mac Pro
Mar 25, 2008, 03:50 PM
I'm trying to remove the front fan assembly on the 2006 Mac Pro and it's giving me a hard time. The top part near the screw popped out easy but the bottom is stuck. I'm not sure how much force to use or in which direction to pull, straight out of the case (2) or upwards toward the hard drive bays (1)? I tried easing it in both directions but it won't budge. Thanks.

You need something like a PCI slot-cover to use as a puller. Tuck the short bit under the plastic at the top-right of your photo and give it a good (but not excessive) tug in direction (2). As long as you've removed the screw, it should pop out OK.

Thanks. I already did that. The top right (near the screw) is completely lose already. Something is holding it on the other end. Where are those clips exactly? Is there one where I marked 'stuck'?
edit: never mind, it's out. It just needed a good forceful tug. I love plastic latches. Thanks.

For anyone who comes to this thread in future, I meant the top left of the photo...
Sorry for any confusion.

Maybe I should mention in case someone finds this that there is a rail on the left side where it was stuck. It's kind of tight but the assembly slides straight out (2) after unlatching it on the right. Not really difficult at all, if you've done it once.

I spent quite some time going over this yesterday trying to add a new SATA optical drive to my Mac Pro (early 2008). On the 8 core models, there is a screw on the left side of your picture as well.
To get to it, you need to remove the CPU cover. You do not have to do anything to the RAM risers or assembly, just leave them alone. To remove the CPU cover, reach down toward the motherboard and grab the lip of the cover. Gently pull outward, then up, and it should come right off, exposing the heatsinks for the CPUs. The other screw it tucked under the lip of the fan assembly. You will probably have to get close to the computer to see it, but it's pretty obvious. Once this screw is out, along with the one on the motherboard, then the fan assembly gently comes out.
I shredded my fingers and probably came close to breaking my computer trying to yank the dang thing out before removing this screw. I found some documentation on Apple's site about adding a RAID card and it described this process for removing the fan assembly.
I'd be happy to post a video tutorial on my site if anyone is interested.

Err.. We know about the screw, thanks.
From the OP:
The top part near the screw popped out easy...
and from post 2:
(2). As long as you've removed the screw, it should pop out OK.
and from post 3:
Thanks. I already did that. The top right (near the screw) is completely lose (sic) already.
Or are you saying there's a second screw on the later model?
*edit* Ah, that is what you meant. Sorry. :o

Per your edit, I assume that you know that I do not mean the screw that attaches to the motherboard, but a new one, I believe, that screws to the lowermost heatsink (for the second CPU). I think this was added in the early 2008 edition of the Mac Pro, which is why it wasn't discussed earlier. I just wanted to post it since this listing comes up in Google searches on the subject. Since I was one of the readers of the post, I figured I would help future upgraders with that model Mac Pro as well.
Since there isn't much mention for people trying to update the early 2008 model Mac Pro, I'm videoing a tutorial now to place on youtube for this very reason.

The RAID card installation is the clearest with lots of pictures.

As promised, I posted a video for removing the fan assembly in a Mac Pro (early 2008) model. This will hopefully help a few of you out there.
