You're at a 23C delta with a particularly heavy load game, but not honking down ton of power otherwise your core temp would be much higher.  For a typical 70C at 400w, 80C-90C vram junction would be expected, hence the 10C-20C delta I cited.

 
70C on the GPU sounds high like you don't have enough airflow around the card. My zotac 3080 didn't get that hot and it only pulled 372 watts according to after burner in game.

Heh.  You're the only one I've ever heard say that.  This is with a 3080 Ti or 3090 FTW3 Ultra at over 400w average sustained in 4K120 VRR gaming. Plenty of good fast case fans, fast card fans, mesh case and room air circulation.

those same 2 tests back 6 months ago when the Cards were new from Evga and prior to installing Water Blocks were about 72c - 73c, so I managed to shave almost 5c off the load temps with new pads, putty n grease ;)

While your results are great and any improvement is usually worthwhile, most people shouldn't be randomly pulling apart EVGA cards to get a few degrees improvement.  They already have some of the best thermals out there and there are risks of making it worse or damaging the card if you're not careful.  The first step is always to get a good case airflow setup.

Agreed...I have been taking cards apart and installing Water Blocks....then re-installing stock air coolers (to sell the Cards) for years, so not a big deal for me....although a little extra care going into the $1700 CDN, 3080Ti FTW3.......actually the 1080Ti's and 30xx Series Cards are pretty easy to disassemble / re-assemble vs the older previous cards......those results I posted were in a very old Coolermaster Case with the side panel off ;)
 
Yes defintely.....I wouldn't recommend disassembling a new Card just to change grease (although the stock stuff that was on the die was pretty bad, as in really hardened and didnt cover the entire chip).

Hey thanks, really appreciate the clear qualification and warning, you're obviously an expert.  I've been monitoring the Reddit PC subs a bit, swapping pads is the flavor of the month over there, any hint of poor vram temps (or just normal temps) even with bad case cooling, and a bunch of noobs are jumping to recommend a pad swap.  People are buying cards and thinking they need to swap pads before they even run it, lol.  It's almost as bad as the constant recommendations for undervolting.

OP, here's a thread with a couple nice 3080 / Meshify-C setups.
 

 
Probably want to avoid front AIO as they are usually restrictive to air flow.  With plenty of fan speed and ~20C ambient temps the card should be about 70C at ~400w.

I don’t believe I’ll need any extra holes, but it may not end up as pretty. If I’m not mistaken OP on that thread has a CLC?

Ok, the 3080 is in, along with my new 1000W PSU!
 
My cooling setup is a Noctua DH-15 cooler, two Corsair 120mm fans intaking on the front, two stock case fans in rear and rear-top exhausting. No liquid involved. With some testing the last couple days I peaked the GPU in a benchmark at 84C, which was one degree above the setpoint for the RTX 3080 in EVGA's Precision X1 software, running aggressive fan curves. Otherwise during normal gaming I haven't seen anything above 76C. My processor temps have increased an average of about 2-3C, which was surprising because this GPU runs quite a bit hotter than my 2070 Super did. Ambient temps between 21-24C, which hasn't changed.
 
The setpoint of 83C just... feels high. I don't really know what I'm talking about, but it seems higher than it should really be. I'm sure I'm just being paranoid? The Precision X1 software allows some room for adjusting, but I don't feel comfortable playing with settings I don't fully understand. Any thoughts?
 
Here's a pic of the setup. Notice the card sagging... I will be 3D printing a bracket to support the right side ASAP. In the meantime, I used one of my extra mouth-guard cases that's exactly the right height wedged in a divot in the GPU end-cap to support it... not ideal.
 
EDIT: I'm having some trouble getting pictures to attach to this post. Not sure what I'm doing wrong. Oh well. You get the idea.

I didn't recommend adding fans.  I recommended exactly what I wrote.

My mistake for misunderstanding. In case you haven’t noticed I’m pretty new to this, and I assumed “try some [fans]” meant I didn’t have enough air flow and needed to add more. Didn’t know there was a difference.

I’ll see if I can fix my current fans. If not I’ll consider looking into purchasing some. Got a few additional routes to explore as well.
