3070 Gigabyte RTX 3070 Gaming OC Thermals issue

[Lemings_]

My current setup is:

• CPU: AMD Ryzen 7 5800x
• CPU Cooler: NZXT Kraken X63
• GPU: Gigabyte RTX 3070 Gaming OC 8G Rev 2.0 LHR
• Motherboard: MSI B550 Tomahawk
• Case: Phanteks Eclipse P400 Tempered Glass Edition (With the solid front panel replaced with a perforated one from a different edition of this case)
• PSU: Corsair TX-M Series TX650M 650W Gold

I have started looking into some thermal and possibly performance issues related to my GPU. I've ran some FurMark 1080p benchmarks as well as 10 minutes of stress tests. Before all of these I've ran the Automatic Tuning utility in the new Nvidia App, which set it to 93% Power Maximum and 81°C Temperature Target. Fan Speed Target is Automatic. 

What brought this whole thing on was that while gaming, in some more and even some less demanding titles I hear fans suddenly spin up to maximum RPM and sounding like a jet engine for a few seconds every now and then.  

Because I have the AIO Radiator in the front with fans pulling air through, I thought that it was the GPU not getting enough fresh air. So I ran some FurMark stress tests on the GPU with the side panel on and off.  

With the panel on, the GPU starts thermal throttling very quickly, drops to around 1500MHz and stays just above 80°C. With the panel off, temps are sitting between 79°C and 80°C, clocked at around 1650-1700Mhz.  

I have added 2 intake fans on the top of the case a few weeks ago as I was repasting my CPU, but sadly this didn't solve the issue and I still hear the fans blasting off occasionally (once during the panel-on stress test as well).  

Another idea I've had was that in GPU heavy loads, the front intake fans aren't spinning fast enough because the CPU isn't getting hot, starving the GPU of fresh air. Sadly I can't move the Radiator to the top of the case as it would interfere with the heatsinks on the motherboard.  

Something I've noticed while having HWInfo up on my 2nd screen was that GPU Temperature and GPU Hot Spot Temperature could differentiate by as much as 23°C. After reading up on this, apparently this is a pretty good indicator that I should change the thermal pads on my GPU, something Gigabyte cards seem to have been struggling with. I'm not entirely comfortable with doing this so it's kind of a last resort.  

Here are the csv from HWInfo for the stress tests:

Does anyone have tips on how I should proceed with this issue?

how are your fans set up?

On the front, 2x140mm on the inside of the radiator pulling through it. On the top, 2x120mm as intake, and a 1x120mm on the back as exhaust

start by moving one of the top 120mm fans as an intake in the front and swap the other top 120mm fan to exhaust and have it in the back of the case.

This is how I have it right now. Green are intake, red is exhaust.
