Do I need more fans for this rig?

I'm building a PC, and I'm wondering if I need more fans. I want to overclock everything, so cooling is important, and I'm not sure if the three that come with my case are enough. Here are the components:

CPU: Intel Core i5-4670K
GPU: EVGA GeForce GTX 780 SC 3GB
Motherboard: Asus Z87-Pro
RAM: Crucial Ballistix Elite 4GBx2 DDR3-1866
SSD: SanDisk Extreme II 240 GB SATA
HDD: Toshiba Desktop 7200 2.0TB 7200RPM SATA
PSU: Seasonic M12II-850
DVD Drive: LG Electronics Optical DVD Drive
CPU Cooler: Noctua NH-U14S 140mm
Case: Fractal Design Arc Midi R2 (the one with the solid side and extra fan spot)

As I said, the case includes 3 fans, but I believe it can hold 8. I'm wondering if I should buy more, and if so, how many, which size(s), and are there specific models which work better, or should I just get some that match the 3 included (silent series r2 I think). Also, if anybody can provide advice about arrangements (should air be sucked in through the front and blown out through the back, how many in and how many out, should one blow through the hard drive cage, etc.) that would be great. Thanks in advance for any help.

You shouldn't need any more fans, make the front intake and the other two exhaust, then try to position the cpu cooler so it follows the air flow(front to back).

Less is more. Only add fans if the current solution is lacking.
And you can only determine if it is lacking by running it under load.

Build it, test it. See what it does.

before I get to ya question, I'd rethink the choice of the SC series card..... you are paying quite a premium for a factory overclocked card. But all the other factory OC'd cards from Asus, Gigabyte, MSI not only use great aftermarket coolers but also use custom PCBs and beefed up multi phase VRM circuitry whereas the EVGA SC just changes the cooler and uses reference PCB and stock VRM. That's why ya don't see it do to well when overclocked.

All four manufacturers - ASUS, EVGA, Inno3D and MSI - made something special out of their GeForce GTX 780. The card that impressed us the most, however, was the ASUS GTX780-DC2OC-3GD5. The new cooler works like charm, and its performance is clearly reflected by the test results. The card also manages to stay very quiet and offers the best overclocking potential thanks to the new cooler. ASUS earns the Gold Award for its card.

We can't leave out the card from MSI. While it's slightly less overclocked and has less overall overclocking potential than the cards from Inno3D and EVGA, it's extremely quiet under load, the most silent of them all. It's also significantly cheaper than the other three, so if you're not planning on extreme overclocking, this MSI card is the best option.

An honorable mention goes to the Inno3D card. Out of the box it's the fastest, and while you can yourself get the other cards to the same level of performance, it's nice to have it guaranteed if you're not an experienced overclocker.

The EVGA ACX Superclocked also isn't a bad card. The only problem is that about the same amount of money will net you the ASUS card, a card which is superior in terms of cooling, noise and overclocking potential. EVGA will have to drop its prices to MSI levels to keep its card interesting.


If this is a gaming box, I'd switch to the MSI GD65 also ....

Couple that with good looks that carry the dragon theme through the board, and you have a winning combination at $189.

Now and again a motherboard appears that is so obviously brilliant, and so affordable, that we wonder if anything will be able to top it. For a while that crown was held by the ASUS Sabertooth, both in X58 and then P67 variants. Then MSI stole the crown with the Z77 MPower. Looking at the Z87 GD65 Gaming we think it's going to take something extraordinary to top it, such is the perfect storm of price, performance, features and looks.

The switch to Military Class 4 has given us an extremely ready overclocker too. You're always thermally limited when overclocking and the i7-4770K is one of the most demanding around. Considering the amount of cooling we're using we think that although the GD65 is capable of bringing 5GHz from our i7-4770K you'd need a proper water loop to make the most of it.

Performance is outstanding. The stock results were a particular highlight. We know a lot of people still just like to put their CPU in and go, without overclocking it first. Despite how easy it is these days we know that the fear factor still exists. So you'll be glad to know that the MSI Z87 GD65 Gaming really rocks hard even at stock settings. Naturally the overclocking is blistering too, with some OC3D records broken.

MSI have laid the gauntlet down to all the other manufacturers. Gorgeous to look at, blistering performance and all at a very affordable price, the MSI Z87 GD65 Gaming is not only the new benchmark for Z87 motherboards, but probably for all motherboards.


Finally for the same price ya can up ya cooler a bit

Ok now to the fans..... hard question to answer not knowing how ya gonna run them, what noise you are willing to put up with, how high ya OC..... I have 5 case fans and 5 (pondering 10) rad fans with twin 780s and a 4770k....I don't think you wanna go there.

Overclocking makes heat .... figure max theoretical darw at 300 for the GFX at 20% OC and 135 for the 4670k..... If you wanna run the fans at low speed, and do big overclocks, I figure 75 watts per fan ... so 5 or 6 shud cover it.....I'd add (3) Phanteks SP140s in the top relocating the one that's there to the front. Grab a Fan PCB such as the ones from ModMyToys (FrozenCPU.com) or the Phanteks one coming out at the end of this month or just get 3 cable splitters and put 2 fans on each CHA header (also from FCPU) on the MoBo.

But again.....might as well try it like it arrives and see how it goes. That's what I did .... was planning 10 rad fans but I'm finding I do just fine with 5.....of course "fine' is a word some of us feel just doesn't quite cut it.

Wow, thanks for the extensive list of advice. I was going for the EVGA because it was actually on sale for under $500 when I first looked, but now it's not, so I'll probably switch to the ASUS. As for the motherboard, I'm going to stick with the ASUS one, because its 20 dollars cheaper, plus it comes with wifi and bluetooth. And thanks for the cooler recommendation, I'll just have to make sure it fits with my high profile ram. And for the fans, I guess I'll just try it as it is and see if I need more. One more question, should I blow the front fan through the hard drive cage to cool them off, or will they be fine without it.

The Asus is $185 at newegg / MSI is $158

As for the WiFi / BT .... I have the Maximus VI Formula (M6F) and it also has WiFi / BT .... since disconnected since it was causing conflicts with the LAN driver ... so prolly wanna use one or the other... If ya can swing the extra $100, highly recommended.

The Crucual ballistix also comes in low profile..... every memory does, there is no performance reason for the tall RAM, just looks
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

these also fit anything

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

And these CAS7 1600s are faster than the CAS 9 1866s
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I'd do two ins in front and 1 out in rear so as to insure that you have positive pressures and thereby utilize the inlet filters.....any air collecting in top of case will go out the holes there.
