GPU cooling problems

[halo3metallica]

Hello everyone, I have a gtx 1080 ti plopped in a s340 case at the top pcie slot. I'm noticing an idle around 35 with a custom curve. Not too bad, but after reading around that under load it really shouldn't surpass 82 C I find my self at around 76 C in low graphics settings on certain games. I have a h110i with the fans in front of the radiator set to exhaust and the two case fans set to intake on the rear and top. I discovered one of my fans wasn't PWM and after changing that I've dropped about 3 degrees. However, this is still High. Looking for some suggestions.

Pictures would really help.
Normally you would want the exhaust through the top, or rear, for natural air flow.

For best air flow.

The H110i should in contemporary belief placed in this way, with the fan blowing air from the radiator.

The preffered configuration isn't an option with this case. There is a little piece for the wires that blocks the radiator from being directly in front of the case. I will try inverting all my fans though and seeing how that works

That did me a solid 10 degree drop. Is there anyway to improve it further? Bigger fans on the front or the top and rear?

That's great!
So your temp is about 66 degrees now? That's decent I guess.
Larger fans will increase flow, and reduce sound. I do not know how large of an impact that will provide though.

I figure a larger exhaust fan on top wouldn't really help. But the back of the Case only supports a 120mm the top is currently a 120 but can be a 140. If that could get me cooler I'm willing to try it
