GPU Nvidia 3080 TI FE - Idle Memory Junction Temperature

Just got an NVIDIA GeForce RTX 3080 Ti Founders Edition 2 weeks ago. I run it in a SILENT BASE 600 with many fans: Silent Wings 5x140 1x120

Found out in HWiNFO64 7.06-4500 that Idle Memory Junction Temperature is max 70 Celsius when fans are low. If I set 100% case and card fan speed, I never get I below 60 Celsius, with all setting on stock. Gaming temps are okay, BF goes max. 95 Celsius

Did some mining test, Memory Junction Temperature went up to 110 degrees for a few moments. D

Unfortunately, I did not check idle temps when the card was brand new.

So question are:
1. Could the mining test harm the thermal pads?

2. What are your Memory Junction Idle Temperatures?

Thanks!

I have two 3080 ti now and at stock they produce more heat than my EVGA FTW3 Ultra 2080 tis did overclocked. 

The cases that they are in were fine for the 2080 tis but have failed with the 3080 tis. 

Both cases are of a high airflow design but they are not pulling the hot air around the GPUs fast enough. So they heat up. 

 

I have had two successes with the ASUS Rog Stix 3080 and an MSI Gaming X Trio 3090. 

I thought that the 3090 would be a cooling challenge but it was not since it is in a Cooler Master H500M. I know now why it is still near the top of Gamers Nexus case chart.

The 3080 is in a Cooler Master H500 ARGB. I have used these in three builds with Noctua nh-d15s and that combo is great at moving air across the GPU to keep it cool.   

 

The cases that have failed are a Corsair 5000D and a Cooler Master H500p Mesh. 

The H500p Mesh has an EVGA XC3 Ultra 3080 ti and you would think that with a similar design to the H500M that it work fine but it doesn't.

Fortunately adding a 60mm Noctua fan below the GPU had temperatures drop by 10c so it is fixed.

 

The Corsair 5000d is using 7 Corsair fans and none seem the effect the GPU at all. 

I tried the 60mm Noctua fan fix that worked on the H500 Mesh but it had zero effect on GPU temps.

So today I will try another fan configuration but I am not optimistic.

I have ordered a replacement in the form of a Lian Li O11 Dynamic. The idea is to have 3 120mm exhaust fans right below the GPU.

 

Cooling these GPUs seem to be a challenge but I would rather spend money on cases and a few fans rather than taking them apart to add pads and risking damage.

Yeah, the FE cards have crap for thermal pads. I was in your same situation, same temps and everything. 

 

Might want to look into:

RTX 3080Ti FE great results after thermal pad replacement. : nvidia (reddit.com)

 

Now I'm at 70c core and 82c memory max @70% max fan. 

Best of luck to ya. 

I did this to my 3090 fe with thermalright odyssey 1.5 pads and made a good difference before I put the water block on.
