New 1080 Ti Running at 84 C under load/need fan help

[bigtyme07]

Hey guys so I have a new EVGA 1080 Ti FTW3 and after RMA'ing 2 of them due to poor thermal paste application by EVGA I finally got one that doesn't go up into the 90's. However, with the side panel on my NZXT H440 I do get temperatures up into about 84 C once I take the side panel off temps drop to about 76 C and I have an ambient temperature of about 23. I have to assume that it's my case fan setup that is giving me these temperatures I had to put my CPU AIO water cooler on the front in a pull configuration because my new mobo wasn't giving me enough clearance to mount in on the top like I usually do. I'm going to post pictures, let me know what you guys think I should do. Thanks!

You have 4 Exhaust and 2 intake, right?
Need to add an intake at the bottom of the case.

There's a PSU shroud down there though

That case has serious poor airflow. If you want your Ti to breathe fresh air, you're going to have to eliminate the PSU shroud and get 1 or 2 fans on the bottom blowing upwards to the video card or find a way to get better airflow through the case to feed that card.

when you add the fans, get some higher airflow fans, more cfm the better when not pushing through a radiator.

So I was trying to do that by increasing the case fans but I only have 3 pin case fans and after much research it seems like they can only be controlled by either 1) A fan curve based off cpu/mobo temperature or 2) a physical fan controller, so I can't manually increase fan speed is that correct?

If you install a drive bay fan controller you can control the speed of the fans manually within a certain range. The low end control will be limited by the impedance of the fans since you would be relying on voltage rather than PWM.

I am going to call BS on it being the case. I used to run ZERO fans in my case. The only active cooling was 1 fan for the CPU and the two fans on the GPU and 1 fan for in the PSU. Even at that, I had all the fans set to off while the loads were low so literally the only fan spinning was the one on the PSU when I wasent gaming. My temps were fine. When I did game, I could still easily maintain under 70C with the fan speed not exceeding 60%. Oh, and I have a GTX1080Ti from Evga as well.

I have since added two fans, but even so they have had absolutely zero effect on the GPU's temp. If I set the GPU fans to 100%, I can run benchmarks on loop and stay around 60C on my GPU. So I am going to guess it's something more than just his case fans since we both have the same brand of 1080Ti and I can turn all my case fans off and it still doesent matter.

what are you using to stress your rig? are you gaming or running 3dmark? anyhow i would try reversing your top fans. it cant hurt...
