Heyhey everyone, I have the fractal design refine r5 chassi and a gtx 1070 asus dual oc, and the temps for the card goes up to 87 when I play heavy games like ARK or PUBG, basically any heavy GPU game. the card seems to OC itself up to around 1800-1970 MHz but I think that's standard for this GPU.

I'm quite positive that the temp-problem is becuase of my airflow in the case, because when I touch the side of the case it's hot on the upper side of the case.
Can anyone explain how I set up the best possible airflow to that I don't have to worry about temps anymore?
I have the z170-A-pro mobo and 2 case fans with 1 CPU fan, so I think I should be able to fit 2 more case fans on the mobo. Any help would be greatly appriciated

As envy14tpe says and as i was going to suggest. Top exhaust will definitely help seeing as you are getting hot spots there. You have a choice of how many fans you want. Keeping good quantity of air coming in helps feed all the components you have in the case, with a good strong exhaust at the back.

Yeah, it's newly built so no dust. CPU never goes higher than 60 under load.

One fan is in the front and one's in the back. This is where my knowledge isn't really worth anything. When I put my hands where the fans are, I can feel the air but not alot, so that must be outtake right? I really don't know what I'm talking about here as you might be able to tell lol. Just now I put them on 100% fan-speed but I put them on 50% when I'm playing games.

The case comes with one front and one rear fan. I would add another 140mm to front and a 120mm to top rear. If you get fans that rpm don't break 1450rpm. You could plug them into mobo or psu (via molex).

Also you could remove HDD cage(s) if you don't need them to improve air flow from front to back.

Have you played with the GPU software. For instance, I use MSI Afterburner, and in it I am able to set the fan speeds based on temps. Can you do so with Asus's software? If not you can use MSI's.

Yeah, this was how I figured out it was airflow, highest I've seen with the sidepanel off is 77 which is apparently still alittle high but only by a few celsius, tbh I'm happy if I can get it down to 80 while under load.

Yeah I did some research before posting but the negative and positive airflow is too much for me to graps atm, the blog I read about it was very confusing. So I posted here to see if there was kind of a standard way to set up your fans that grants good airflow lol.

Yeah, I use Afterburner to check temps and control fanspeed, I usually set the fanspeed to 50% while gaming and I think that should be enough to not get a nuclear meltdown in my case.
Could it be that the 2 current fans are "outtake" fans because I haven't turned them or anything, I just plugged them into the mobo.

Nothing really to grasp, its all just a basic case of one or more fans sucking cool air in, and one or more fans blowing the warm air out.

I have a simple setup of one 200mm fan at the front, and one on the side sucking air in, and one 200mm fan on the top of the case blowing air out, i also have a 120mm fan on the rear, sucking air out. My CPU cooler has a fan on the heatsink, which blows through, and gets exhausted by the rear fan.

Easiest way to tell if your fans are positioned right....do you see big logo?...that is direction air is pulled in and pushed out the back.

Your GPU fans only hit 50%? wow. Your GPU must run cool. Mine jumps to 80% at 60C and runs so until 75C. And normally I get around low 70C at this 80%.

Okay, the site I read was probably for more experienced people, this seems easy enough, I just want good cooling but I don't know where to put the fans, but since the heat is at the top of the case, do you think I can put them at the top so the hot air blows out of the top?
