General Hardware questions

Hey all, this is my first thread on these forums, and I apologise if I posted in the wrong forum, but I have several questions that span rather widely so I thought hardware may be appropriate.

1. I'll pick an example: GA-Z97X-Gaming GT

On the back panel description for the USB 3.0 ports, it lists 2 of them belonging to the chipset, while 4 more belongs to a Renesas USB 3.0 Hub. My question is, is there an easy way to find out, from the specs alone, if those USB ports have shared bandwidth? Because on some other Mobos (I can't remember from my top of head which) have stated that it has 2 such hubs for the same number of USB ports, hence my confusion.

2. I plan to build a rig that is going to use 2 MSI GTX970 Gaming 4G cards (though I have zero plans to use anymore GPU's in the same rig), and I am working entirely on air cooling, no plans to mess around with Liquid cooling. I have been thinking of a Lian Li case:http://www.lian-li.com/en/dt_portfolio/pc-7h/

It has 2 fans in the front, one at the back with options for 2 more at the top and one at the side. Although it appears that the drive bay will get in the way of the second GPU, it is removeable (which may work in favor of cooling), and I can instead install my Harddrives and SSD into the 5.25" bays.

Is a case like that good enough to cool two GPU's and a CPU?\

3. Lastly, would overclocking cause any noticeable damage to either GPU or CPU, assuming that I fix the voltage at stock, and keep my temperature level or below that at stock level?

Thanks a lot in advance!
 
1) Shared bandwidth? Huh? Explain please?

2) Yes that case is good enough since it has placement for a side fan and top exhaust fan.

3) No.
 
1. I cannot for the life of me remember what review I read, but it was a rather recent one, and it mentioned that the USB3.0 ports at the back all shared its 5Gb/s bandwidth rather than having 4 individual 5Gb/s bandwidth. Although I realised that it doesn't matter all THAT much, since external HDD doesn't seem capable of using that bandwidth on its own.

2. Thanks, although I do have another question. For the side fan, should I install it as an intake or exhaust fan?

Click to expand...

1) That info might be found in the motherboard's manual.

2) As Heavenscloud said, that side fan should be an intake.
