Extra fan to feed blower style GPU?

I'm running a Fractal Design Define Nano S with a Corsair H100iv2 up front running intake using Noctua PPC 2000RPM fans, I am using another of the same to exhaust on the back.

I

m also running an Asus GTX1080TI Turbo Blower style GPU

 

The case also has room in front of the power supply to run a 120mm fan. 

 

I was thinking of grabbing another noctua to put there which would push fresh air directly onto the blower fan of the GPU.

 

Is this a good idea for reducing temps under full load or would it be a waste of a fan?

Yes, help give it its own fresh air is always a good idea.

It will help, but this card really needs it's own AIO.

If the current temperatures of it aren't of concern, then maybe not.

 

However it would be good for piece of mind :3 Also you're introducing another fan to help a fan, so noise probably won't really be any lower either way.

 

I once did the unthinkable, back many headphones ago...

I split an audio split, again

it never gets above 71c during gameplay or FurMark with the fan curve I have on it. The fan noise is negligible because whenever I'm gaming i'm wearing AudioTechnica ATH-AD2000x so I don't hear it anyway. 

 

I'm just curious if an extra fan would make it even better

Yes my boi. All the fans. Thats how I built my S210 and it is great. LOW rpm on EVERY fan and my temps are still way lower than the stock fan config

CPU: INTEL Core i7 4790k @ 4.7Ghz - Cooling: NZXT Kraken X61 - Mobo: Gigabyte Z97X SLI - RAM: 16GB G.Skill Ares 2400mhz - GPU: AMD Sapphire Nitro R9 Fury 4G - Case: Phanteks P350X - PSU: EVGA 750GQ - Storage: WD Black 1TB - Fans: 2x Noctua NF-P14s (Push) / 2x Corsair AF140 (Pull) / 3x Corsair AF120 (Exhaust) - Keyboard: Corsair K70 Cherry MX Red - Mouse: Razer Deathadder Chroma

Bit of an AMD fan I suppose. I don't bias my replies to anything however, I just prefer AMD and their products. Buy whatever the H*CK you want.

Given the way that blower style coolers work, you can't really "force-feed" it air the same way you would a passive heatsink or even an open-air cooler. The suction generated by that high-rpm fan is very directional, and given that cases aren't really sealed, it's not starved for air by any means.

 

So technically, yes, it's a waste of a fan. You won't hurt anything by adding another one, but if you have something else you want to save the money for, I'd pick that something else every time.

I actually tried it with a stock corsair fan just now and there was literally no difference in temps  with it or without it during a 20 min FurMark test
