Safe to put 2 80mm fans right in front of GPU fan?

[Antisthenes]

Got a Cooler Master Elite 110, a Gigabyte 1070 Mini GPU, and a 6700k cooled by H80i V2. Will the GPU be damaged if two 80 mm Noctua NF-A8 exhaust fans are placed absolutely right in front of the GPU fan, with almost no room between them at all, perhaps only a mm, but airflow in the same direction?

Without the exhaust fans, will temps be low enough in the case for the 6700K? Got a small Corsair SF600 psu about 2 cm below the roof of the case, so guess its fan will blow some of the hot air near the roof outside the case, right?

If the two 80 mm fans are safe right next to the GPU, how does one use the rubber mounting screws to attach the NF-A8 when I can't see how there is room to use pliers down at the bottom rubber screws, since the two fans are at the floor of the case, right next to each other.

The rubber screws can't be drawn at both ends, one end has to go through the case wall first, and then one can pull the other end through the hole in the fan frame, but the screws are not that long, so can't see how this is possible in the small space of the CM 110. Any other screws I can use?

Bumping this, since I need help now, when putting the mITX together.

It's usually not a good idea to put fans in series pushing air in the same direction. They have to spin at the same rate and same amount of cfpm of air being pushed. If one is slower than the other it creates resistance and can actually hinder air flow.

I remember when the XBox 360 first came out and there was a fan device you place over the rear fans. It turns out that it was creating turbulence and many consoles actually over heated.

The 1070 is an uber cool gpu. I doubt extra fans are needed.

Thanks for reply! But what about the 6700k with the H80i V2? Without the two 80 mm fans, the CM 110 case will have no exhaust.

After looking at pictures of your case, cpu cooler and gpu I think I know what you're talking about now.

I don't think it should be a problem. The can on the cpu radiator should be sufficient to push air out of the case. If it allows you to mount another fan on the other side of the radiator, it should be fine too as long as the airflow is the same direction.

On a case like that I would have gone with a reference cooler. But it looks like it has good airflow and again with the 1070 being a cool card, it shouldn't be an issue.

Read that it's recommended to mount the radiator fans to push air into the case, and not use them as exhaust fans. But with no 80 mm exhaust fans, it's best to use the radiator fans as exhaust?

A bit off topic: in order to discharge static, is it enough to touch the black-painted metal parts of the case? Ask because I read that one should touch metal that is not painted, but didn't know that when installing the components.

Push air thru the radiator and into the case? WHAT?! The point is to move the heat from the cpu out of the case. By taking outside air and letting it pass thru the radiator and into the case... you're keeping the heat contained in the case. That makes absolutely no sense at all.

The metal doesn't have to be bare to transfer static discharge. Static electricity will "jump" before your skin even touches the metal.

It's my first build, so sorry for the noob questions.

I have touched the metal frame of the case every minute or less while building, on a wooden table and wood laminat on the floor, but read now that one must touch the case all the time. Hope I didn't volt my RAM, CPU and mobo. Or did I?

Just received an anti-static wristband in the mail. Use it now, but no bare metal parts on the case though...
