Your fan speed is built into the video board's BIOS and can be changed by using a utility like MSI Afterburner: http://www.guru3d.com/files-details/msi-afterburner-beta-download.html
I recommend Afterburner because PrecisionX is too buggy. Enable 'Custom Fan Profile' in settings and set your fan speed to increase as the temperatures get higher. You should be at your maximum fan speed around 70°C while keeping your fan speed around 30% at idle.

I know those software can be used, but before I do that, I want to clear up one thing. Is 37% fan speed too low to handle 80C temps when under 100% load?
 
Is this a case of "poor" fan curve design, or indicative of a faulty GPU, or indicative of terrible airflow in my casing?

When the fan curve was calculated by nVidia they were more concerned about 'silent' operation and therefore keep the fans running at the minimum speed for stable operation while just barely keeping the temperatures below their maximum threshold. Their fan curve is fine for an office computer but not so much for someone who wants to do any gaming and is why we all enter our own fan curves using either PrecisionX or MSI Afterburner.

single-fan ITX model ? (02G-P4-2962-KR EVGA GeForce GTX 960 SC GAMING)
Take a Photo of your Computer Case with the Side Off and Post it here for users to review the Air Flow.

Mine is the 3962 model.

The cables are a mess, because there are so many of them from the B1 EVGA unit I just got. I'm not sure if this is contributing to weaker airflow.

One thing I also realized is, with my 750 SC and older PSU, the case fan would top out at 1600RPM. Now though, it spins until 2100RPM. Some heat seems to get stuck in there.

Any suggestions are welcome!

Are your Temps posted above with or without the Side Cover installed?

Raising your case up would help with airflow especially if it is sitting on a carpet. That is why mine is sitting up on wood blocks that I got from Amazon.

It's only too low if you don't like the fan running that low or the temps on the gpu running that high.

 
Lots of airflow. 

Wouldn't worry about it to be honest. All your temps are good. The 5C increase on the GPU is what is most likely causing the temp increase on TMPIN1.

Ok guys, now I really need some confirmation.
 
This guy is using a Dell Inspiron 660 as well. But out PSU positioning is opposite. Is his correct, or mine?

NVIDIA card vendors (EVGA, MSI, Gigabyte, etc.) are free to customize the VBIOS (including fan speed) of their cards to a certain extent within NVIDIA specifications/limitations.
 
The VBIOS of your EVGA GTX 960 SC with an ACX 2.0 cooler will turn off the fan below 60C per EVGA's VBIOS..Some other card vendors with similar design GTX 960s, single-fan or otherwise with their own version of 'ACX Cooling' (WindForce, Frozr, DirectCU, whatever) do not turn off the fan/s below 60C, but run it/them in a low RPM mode and also will not reach 100% until a very high temperature (even beyond the throttling temperature) is reached..The NVIDIA specified maximum GPU temperature for a GTX 960 GPU chip is 98C.
 
Fan speed curves will also vary between vendors, depending on the vendors VBIOS they've flashed it with..I assume that in this way, "Maximum Performance, Quiet Operation" or similar such marketing claims can be made.
 
As everybody else stated above, your temps are fine but I don't like the fan speed curve on your 960 either, and left alone, that's just the way it is..As you know, you can use the software fan control in EVGA PrecisionX or MSI Afterburner to customize the speed/temp curve to your liking, so just use whichever one you want/works better..Otherwise you would need to modify the fan speed curve your card's VBIOS, which would void the warranty should you need to RMA and you don't/can't flash it back to the original.
 
I'm not going to advocate or encourage you to modify/flash the VBIOS to a different RPM/fan speed curve (even though I've done it to my card) when you can easily use software control, but you can view what it is in Maxwell II BIOS Tweaker if you extract a copy of it with GPU-Z and then Drag 'n' Drop it in if you're really interested.
 
As far as the PSU, I know the stickers were put on upside down on some/older units, but that's been rectified on newer units and yours is correct.
 

That cable management is much better. Excellent in fact. In Afterburner's settings, click the box to 'Start with Windows'. Afterburner needs to be running to control your fans. You can set a constant fan speed instead of a custom curve. Whatever works best for you as far as noise and temperatures are concerned.
