I've mounted a switch to the rear of my case to turn them off with.
As for the additional intake fans, I measured and it looks like I can fit a 60mm fan above and below the 120mm one.
Also, what do you mean by create a positive setup? Do you mean that they all blow inwards instead of outwards, creating pressure inside the case?

Say i have 5 120mm fans with the same CFM.
I'd set it up to have 3 in, and 2 out. Because this creates a small positive pressure which in theory pushes the dust away from the case (in all the small gaps). Rather then having a negative airflow which would be 3 out and 2 in. Thus would make the dust be pulled in, all these gaps.. well in theory.

Wow, omg you're right, 72.6°C is the rated temp for the 2500k from http://ark.intel.com/products/52210?wapkw=ALL(2500k)
I'll have to do something about that....
Movies...TV Series...Music...Games... lots of em

I was almost going to buy that case! thumb.gif
Anyway, was the Twelve Hundred out of budget? It's alot better suited to masses of HDD's.
Have you tried a high perf fan for the "Middle" fan? I don't know what that means but it sounds like it's meant to sit at the end of the graphics cards.
And did you end up trying the sidefan for blowing out?

This + Correcting the fans and the middle fan will draw your temps down alot.
Mind you, that leaves you with no DVD drive.. Seeing as you have all your TV shows and music on HDD's i doubt you use your DVD drive anyway. Even if you use it a bit, you might be interested in doing that and an external enclosure for the DVD drive.

What size are the hard drives by the way? You may be better off getting a couple of 2-3tb Green drives alongside the SSD, and maybe 1x 7,200RPM drive for apps and such if the SSD runs out.

Its normal which is the downside to SLI. My top cards gets to 90 degrees and my bottom at about 60-65 after playing BF3 for about 3 hours...

Yes that is exactly what I mean! I know that each setup/rig is different and you can also go with what Matt-Matt has suggested which will work also. I have 2 140mm and 4 60mm fans on my side panel (granted my side panel allows for this) which have helped tremendously in keeping my case and its internal components cool.

Something else I may suggest, try and get some aftermarket cooling for your GPUs. From the pics you've posted it seems you have them on stock cooling, correct? More suggestions! Don't know if you already have it or not, but download the RivaTuner GPU monitor and check your Ambient Temps. Ambient Temp refers to the climatic conditions in the area where your case is located. For instance, if your room is 75C its likely that inside your case it will eventually get hotter because of the Ambient Temp and all the heat generated from your other components. Hope that makes sense. This is also another factor to consider when figuring out what other source is the cause for high temps.

falcon26 and Sean Webster in this thread say that its normal in an SLI setup for these cards to heat up like this. But that just does not make sense to me, when I have 3 8800s setup in 2 way SLI and as I've stated before my temps don't get any higher than 70C. I know that my cards can go as high as 80 put I would not allow that as that is the peak teamp before damaging them.

Keep us posted!

Thanks, I must say, that the stock gigabyte windforce cooler is better than a lot of aftermarket air coolers, here's a nice and big picture of current GPU coolers, take a look: http://www.ixbt.com/video3/images/gf114-4/gigabyte-gtx560-front.jpg

Then again, I'm still not sure, I am just going off the number of fans/heatpipes, size etc. It would be good to see some tech spec comparisons, or some test results etc before deciding to get an aftermarket cooler. the ambient temp at my house is around 24*C (thats what my air con temp display normally says)

I think I will try a higher powered side fan first, as this will probably be the cheapest option for now, I'll also do some benchmark temp tests with different fan configurations etc and using all the great suggestions. Thanks!

Also, I am tossing up between these 120mm fans at the moment:

http://www.sidewindercomputers.com/de12trblhisp.html
Specifications: 120x120x38mm, 141.96 CFM @ 3700 RPM, 52.5 dBA, 9.60 watts, .80 amps, Maximum Air Pressure 13.21 mm H²O, 12v DC, 3 or 3+4 pin Molex header connector(s).

http://www.sidewindercomputers.com/de12ff.html
Specifications: 120x120x38mm, 151.85 CFM @ 3200 RPM, 53.0 dBA, 12.00 watts, 1.00 amps, 12v DC, 3+4 pin Molex connectors.

This one I don't think I'll be able to hook up to my fan controller, it may pull too much current (this is my fan controller: http://www.nzxt.com/new/products/fan_control/sentry_2 ) max is 10watts per fan.
http://www.sidewindercomputers.com/delffb1212eh.html
Specifications: 120x120x38mm, 190.00 CFM @ 4000 RPM, 59.0 dBA, 24.00 watts, 2.00 amps, 12v DC, 3+4 pin Molex connectors.

So...Anyone know of the best place to buy the delta fans?

Don't even get delta's, they're too plain and loud..
and yes i'm pretty sure that 190CFM delta would blow your fan contoller.. rolleyes.gif

This, or this are the sort of thing you want. Especially for a side-fan!

The Antec costs a bit more and pushes less CFM, but it has a speed control switch on it. The Coolermaster has more CFM and costs less..
So it's all your choice,

P.S Get a blue one to match your case wink.gif

Bit of an update,

I don't really care as much about how it looks or if it has pretty LEDs, I'd prefer it just to actually work better. I have already wasted money on two red LED 70cfm fans and learned from that. I actually want to make the case LEDs orange/red instead of blue. Noise isn't much of a concern as I have music, tv, or some sort of gaming noises pumping normally and this machine is in my loungeroom anyway.

I met this guy at a LAN on the weekend and he gave me some really good advice, Check out this link, he has some really cool pics of machines that he has built:
https://www.facebook.com/pages/Karma-It-Solutions/107970870702

So I ended up buying these products from him:

133 CFM Side Fan:
http://www.mwave.com.au/sku-18010310-Scythe_Ultra_Kaze_120mm_Case_Fan_3000RPM_

Liquid Cooling For my CPU:
http://www.bit-tech.net/hardware/2011/07/21/antec-k-hler-h2o-920/2

All up $107

Problem solved - Hopefully

Thanks to everyone for the advice, i will post some pics when I install it all.

PS.
Should I replace the stock two 80cfm Antec Blue LED fans with my 2x Thermaltake 70CFM RED led fans?
With them basically being intake for the case and cooling 6 disks, will the 10CFM difference be very noticeable in terms of temps of the HDDs? Should I be worried?

No, you shouldn't be worried. Passive cooling is good for 1-2 HDD's but a fan is better. If you have more you'll probably want a fan of somesort, any fan will do really, 10CFM isn't alot especially for HDD's

Anyway, nice sidefan + liquid kit! Pretty good deal! thumb.gif

As Matt-Matt said, no need to worry.

Glad you got it sorted. We look foward to the pics. thumb.gif

My GTX 560's are like that. The top one is always about 75c on load and bottom one is 67c. It doesn't matter. I also have the Ultra Kaze Fans on my H80 controlled by a Lamptron FC6. Since everyone's ears are different personally 1500-1800rpm is almost near silent. 2500rpm is noticeable but not server loud.

Ok, so I got the cooler, and it idles at 25 - 27 *C now instead, staying around here's a screen shot of my overclock settings. Pretty good improvements, it didn't go above 43*C running 3D Mark 11 (3 times in a row.) @4.5Ghz

What do I do from here? Can I overclock my CPU further? Whenever I try and increase any higher than this on my CPU It fails somehow... And This is as high as my GPUs will clock to and stay fully stable (920MHz), before they get too hot and make something crash...I can set them GPUs to 960Mhz and play any game, (but I cannot run benchmark multiple times without it crashing at some point, temp goes up to 92*C on the top card....so I guess cooling is the limitation there.) I have tried increasing voltages a tiny bit too...

338

And here is my 3DMark 11 result running at these settings:
( P8013 3DMarks @ 920MHz ) http://3dmark.com/3dm11/2703047
vs.
(P8304 3DMarks @ 960MHz) http://3dmark.com/3dm11/2451339

I have also updated my gallery with pics of the cooling setup, you can click it in my sig if you want to look.
