If I am following the narrative correctly, the OP did not complain about cpu temps. Therefore I doubt fans or case or airflow is the problem. The only thing hot is his gpu but apparently his cpu is nice and normal.

He could still have an airflow problem even if the CPU temps are fine, anyway it was just a thought "to check" not an answer to his issues 🙂

A bit off the topic. I have a 1080ti with an old MSI Z270 mb. I'm thinking of swapping out with an RTX 4070 super. Would this work in my mb? See specs in my signature. Regards.

RTX 4070 Super is not on the list : msi.com/Motherboard/Z270-XPOWER-GAMING-TITANIUM/support#vga

The Case has four 120mm fans:

Top of case blows OUT
Upper front and back of case each has one fan blowing IN

Bottom front of case has one fan blowing IN thru the air/coolant radiator for the VL120 CPU cooler.

The intake fan blades are 88° F and the outlet fan blades are 87°F.

The ambient temperature is 84° F.

You've hit on an interesting point with the CPU temperatures.  In the prior case (full size Thermaltake tower from 2008) while using the same 9800X3D CPU and VL120 cooler could run the CPU-Z Stress Test for 5-minutes and the max CPU temp stayed below 90°C.  

In this new Thermaltake case, with all the same ingredients, the CPU idles at 46°C but hits 95°C (thermal limit) within five-seconds of starting the CPU-Z stress test.  My IR heat gun shows NO temperature change in the coolant entering and leaving the radiator.  And the inlet temp remains at 95°F when the processor is idle and when all 8 physical CPUs are at 95%.  Must be something wrong with my fan control.  But, the fan control program does show the CPU water pump RPM changing as mandated in the BIOS CPU fan curve. 

I guess I will get some more fans to move more air.

Yeah sounds like an airflow issue then.  Also 84F for ambient is quite warm as well and probably not helping.

I'm off to test my 4070  temps at KSAN (default). BTW, folks, Task Manager / Performance displays gpu temperature.

Say, sorry for the tangent but what kind of performance are you getting with the Crystal Light on that 4070? Decent resolution at decent settings? Trying to figure out if I *really* need to go crazy and get a 5090 considering the issues they're having.

changed the 120mm fan on back of case to blow OUT and moved CPU water cooler radiator to top of case and fan to blow OUT.

Then changed GPU power setting to limit of 80% and changed GPU fan curve to hit 80% at 70°C

GPU temp now stays below 70° C at all times.

FPS in my MSFS 2024 benchmark flight dropped from 85 FPS to 80 FPS but my tired old eyes cannot see that difference.

I just updated my 1070ti for a 4070ti super and my mobo (Gigabyte GA-EX58-UD5), although not the same as yours, is considerably older ... everything works fine as PCI-E standards are backwards compatible. I wouldn't worry too much that MSI do not list the 4070 super as being 'supported', they're never going to back to all their old boards and update the supported spec for new hardware releases, the important thing is the backwards compatibility for PCI-E.  The one thing I would just check is that your PSU is adequate ... do a search and you'll find a bunch of online calculators for this.

Yes, my PSU is 1000W. Installed the card, using the adapter cable, updated driver, works perfectly! Thanks.

At the risk of sounding obsessive, let me remind you that the undervolting takes 10 minutes to set up, maybe 20 more to find your sweet spot, and allows to easily save 5 to 10° under load, and around 60-70 Watts on a 4070.

It can help if not solve the problem of PSU power, noise and temperature all at once.
