SLI Cooling and Configuration

Hey Everyone,

I'm going to be building a gaming rig in the near future but I am relatively new to this whole thing. I'm planning on doing an SLI build with possible over clocking and I know that that can cause various heat issues. I also have several other questions regarding the SLI setup so I will break my questions up into different sections. Feel free to address any and all questions you feel knowledgeable about. In a nutshell, here is my intended build:

Case: Corsair 500R White ATX Mid Tower Case
CPU: Intel Core i5-4670K 3.4GHz Quad-Core Processor
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: Asus Z87-PRO ATX LGA1150 Motherboard
Memory: Corsair Vengeance LP 16GB (2 x 8GB) DDR3-1600 Memory
Storage: Samsung 840 EVO 120GB 2.5" Solid State Disk
Storage: Seagate Barracuda 2TB 3.5" 7200RPM Internal Hard Drive
Video Card: Asus GeForce GTX 780 3GB Video Card
Video Card: Asus GeForce GTX 780 3GB Video Card
Power Supply: Corsair Professional 850W 80 PLUS Gold Certified ATX12V / EPS12V Power Supply

For the Corsair Carbide 500R, there are 2 x 120mm front intake fans, 2 x 120mm top output fans, 1 x 140mm rear output fan, 1 x 200mm side output fan, and 1 x 140mm bottom intake(?) fan. I was planning on maxing out each fan slot with the largest fans possible. I was also planning on taking out the middle drive cage for extra airflow and just keep my HDD and SDD in the lower drive cage. I'm not even sure if it's possible but I was also thinking of strapping an extra 120mm fan to the Cooler Master Hyper 212 EVO for a push/pull setup. I probably will have extra fans anyway since I'm ordering the Cooler Master 120mm Silent Fan (4 pack) and a few Cooler Master 140mm Silent Fans, so I might as well max the case out. I'm concerned though that this will not be enough cooling for my setup. Noise is another concern. I'm definitely aware that there will be noise coming from the case, but I don't want to have issues talking with my wife on the couch next to me or something because I can't hear her over the case fans. I know that having two GPUs creates more heat in the case, especially for the top most GPU. I also know that over clocking creates more heat as well. I have three sets of questions regarding this setup. Especially if you have experience with the Corsair Carbide 500R, input would be greatly appreciated.

1). Are there any major flaws to my intended cooling setup (i.e. certain fans need to be reversed, poor airflow, etc.)?
2). Will this setup provide enough airflow for the two 780s to function under heavy load for extended periods of time, along with an overclocked i5-4670k?
3). Will the Cooler Master Hyper 212 EVO with 2 x 120mm fans attached in a push/pull setup even be necessary/possible/enough for an overclocked i5-4670k?

I'm used to having some noise come from my laptop or Playstation 3 for example when they're chugging away. I'm very comfortable with that, but I'm trying to get an idea of what the noise level I could expect to hear with this setup would be.

1). What kind of noise level can I expect from this setup? I know it's not an exact science but comparisons to something I might have around my apartment (i.e. the sound of the dryer going, the hum of the refrigerator, etc.) as a reference would be helpful.
2). Are there ways to reduce noise level without devastating cooling potential?

Lastly, I have never worked with an SLI setup so the actual configuration and whatnot is a bit foreign to me. I do have some questions though for people with experience.

1). Do you have to configure Windows to run a specific way with SLI aside from installing the proper NVidia drivers?
2). Do games that support SLI automatically configure when you play them? What about with non-SLI supported games?

Thanks in advance everyone.

It will be LOUD, but there isn't much to be done about it.

Your cooling system will be fine, but change the side exhaust to an intake.

You need to enable SLI in the nvidia drivers.

Any game that supports it, will use it without any adjustments required.

Also, MAKE SURE you get reference (blower style) cards.

Adding a second fan to a coolermaster hyper 212 evo will do basically nothing at all. Mostly for show.

Thanks for your input. I appreciate it.

So are we talking loud like I can hear it somewhat or LOUD like my wife is going to hate that it's in our living room and want me to get rid of it loud?

Also, how do you tell if a graphics card is a blower style GPU like you mentioned? Is this graphics card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121769) one of those?

If I have the NVidia drivers set up to run SLI, what will happen when I play old school games like Dark Forces or Classic Tomb Raider or something? Will I have to configure my drivers each time I switch between supported games?

Thanks in advance.
 
Yes that is the GPU cooler style i am talking about.

I would say the noise will be somewhere in between those two. The GPUs will be what it loudest.

If you play a game that does not support SLI only one card will be used. the other card still runs and everything, it just doesn't do any work. Nothing needs to be changed.

Thanks for the info. That helps. Maybe this next question is completely pointless but it doesn't hurt to ask. You can tell me if I'm crazy :). So is there a way in Windows 7 to configure a specific GPU to take the default load for non SLI supported games? I'm thinking that since the top most GPU in the case will generally have a harder time keeping cool, that it will be more prone to wear and tear, hence the lower placed GPU could default for all of the non-SLI performance and maybe balance out the wear and tear over time.

Is this just crazy talk? Thanks in advance.
 
It is simpler than that. Whichever GPU has the monitor connected to it will be the main GPU.

I use the top card in my SLI setup as the main card. Both mine run at the EXACT same temps.

But, yes 'wear and tear' by using a GPU is crazy talk. It isn't like a car, there are no wear parts.

Thanks for clarifying. This definitely helps me out.
