I have a question regarding effective methods to fan cooling. I'm writing off my phone so I can't post specific hardware specs but I will update the OP when I have the chance. This is my first time building.

I'm currently asseming a PC using an i7 processor (partner does video editing) and a 980 GTX. I'm worried about controlling temperature while gaming. I know that the 980 is (typically) at 80C and quite safe at that temp. I'm looking into managing heat via fans.

I'm looking at whether using a number of relatively cheap 120 mm case fans can adequately control the heat. I'm obviously open to alternatives and getting a sole higher preforming fan though I'm skeptical it will fit in the case (which is compatible with water cooling and, once I get comfortable with playing around with my parts, I plan on switching too).

Thoughts? Advice?

 

Update: 

 

CPU: i7-4790 

GPU: EVGA GTX980

Phanteks Enthoo Pro (the PH-ESS614P model)

As long as your computer case has a good airflow, it should be fine. You really don't need too many case fans or you'll just end up with a noisy computer.

My case has only two low-revving 140mm fans, and they are good enough for my air-cooled 4ghz i7 and 780 Ti.

Good cable management does wonders for air flow and in turn cooling. I think getting extra case fans can be beneficial for cooling and air circulation. Unless you're just really worried about heat I think the stock cooler will do the job on your GPU, but getting some case fans still won't hurt.  As far as the CPU I would suggest getting an aftermarket cooler, especially if you plan on OC.

Get a case with not only a lot of fans but good air flow.  My case has five fans, two in front, one in the back, one on top and one on the side.  The last two GPUs I've purchased were both Twin Frozr cards, less casing on the GPU and good quiet fans on the card.  They run cooler than stock GTX cards in my experience, never had an issue with those.  My GPU never gets out of the 60s when I game, only if I overclock it.  I currently have a 580 GTX.

 

I don't know if you want to mess around with liquid cooling on your first go around, you probably don't even need it for what you want to do.

To update, I have the Phanteks Enthoo Pro case. Right now I have a planned 4 fan set up. There are two stock case fans: 200 mm in the front and 1 140 mm in the rear (at the top ofthe case). I want to add in 2 120 mm fans at the top of the case, because the GTX will be fanning heat up and I imagine this will help vent the case better. The Phanteks case is spacious so there'll be a lot of airflow. It has a lot of fan grating, so I think it will air out well.

I actually prefer to have more intake fans than exhaust fans. As in theory it should add more air pressure inside the case and be more effective at keeping the dust out of your computer.

While other people prefer negative pressure (more exhaust fans than intake) since it cools your computer more effectively, but in return, it pulls in dust from cracks and crevices in the case and increases the dust build up.

Whatever you do, just make sure you use air filters on the intake fans and clean them regularly.

I have two 120 mm fans in the front, one 120 mm on the door, and one 120 mm in back.  Then there's a 200 mm on top.  The good thing about my case is that the fans are all three speed, low, medium and high so I could try different combinations out when I first built it.  I've never had to use them on high, but I put a couple on Medium when I got the 580.  You can still barely hear them, and that's only when the room is quiet.

 

You should also get organizers to bundle up cords and wires.  Not having cords and wires hanging all through the case will help air flow in and of itself. 

 

But honestly, unless you're overclocking the hell out your GPU or running SLI, any basic fan set up should be fine for a single GPU.  I still have a 500 series so I can't say for certain for newer GPUS, but I can't imagine they're running that much hotter.

I've never been especially bothered by fan noise. It's a weird quirk of mine. But good point re: fan settings. 

 

I have a number of organizers and I'm slowly working to come up with efficient ways to bundle them up to avoid lose cables that will restrict airflow. 

 

I'm not going to OC the GPU yet. That's likely what I'll do in the future as we get more hardware demanding games come out and the 980 gets more out of date. I'm not a fan of SLI builds because of stability issues (and IMO I think there is poor support for it).

Thanks for the advice. 

 

 

Do you have a place on the side of the case? Like, the part you take off, does it have a place for a fan?

From what little I know you should be fine, but if it were me I'd spread each fan out to pull air out of the case in as many directions as possible (better heat dissipation).

 

Good point. I have quite a lot of fan space (but not sides I think). It's bottom, top, rear, front.

Throw an ice-pack inside of the case.

Done.

good airflow? who needs good airflow? just replace the chasis with a fishtank filled with mineral oil
