This reminds me, I've cleaned my PC plenty of times but never took out my 4 year old GTX 580s to clean them specifically. I'm really worried I'll tear the sli bridge or just break something else.
Should I be worried about taking them out to clean the fans or am really overstating how fragile Graphics Cards are?
Eh, you're overstating. Simple procedure really to remove a card with an SLI bridge:
-Disconnect the bridge by pulling it out at the connection to the card (solid bridges you'll have to remove fully but it's the same procedure.
-Disconnect any power connections on the card.
-Remove the locking system at the plate (ie remove the screw holding or unhook the hold down in a screwless design)
-Disengage the PCI-E lock at the motherboard connection furthest from the face plate. Essentially the opposite corner of where the face plate lock is. You will either have to push down to release it or pull it to the side depending on model. ( http://www.legitreviews.com/images/reviews/1021/gigabyte_p55_pcie.jpg the blue and orange slots on this picture are PCI-E and use the "pull away" lockdown design. http://hothardware.com/newsimages/Item17921/MSI_Z68A.jpg the blue slots on this one are PCI-E and use both the hinge lockdown that you have to push down to release and the "pull away" design)
-Pull the card straight out. It's seated fairly solidly so you will have to give it some effort. If it's not moving at all you missed a connection.
To put it back in you just reverse the process excluding the PCI-E lock. That should engage when the card is seated properly similar to how a RAM slot works.
All that said, removing the card for air cleaning is optional if you can get the nozzle for compressed air in close enough. Hold down the fan and put some blasts down the heat sink. It should be enough to dislodge most dust and debris that accumulated there.
Now back on the original topic, you know what the really sad thing is? I do system replacements for banks, stores and similar and those systems make this one look pristine by comparison. Picture systems that have been in use over 8 years (one project had systems running 95 when we did an XP swap out and that was when windows 7 just came on the market) and the last time they were clean was when they were originally installed. THAT's tragic.
