Memory temp and Hotspot on a 3080ti?

[Kumoko]

it is summer RN and just wondering if i should b concerned as my memory junction reach 96 and hot spot at 88-90 at some points when things get intensive while my GPU temp just sits at 78-81

AMD CPU is also getting at some point that 75C lol

Idle temperatures are mostly meaningless, and those temperatures could be explained by a number of things, from "prefer high performance" setting in the nVidia control panel (not saying OP is using this nor that the idle is bad if not, but just saying), an overclock with extra voltage, a summer season, a cooling configuration that isn't amongst the best (some learn towards a mix of being more quiet with good enough temperatures, for example), or a number of other things.

Load temperatures are by far what matter more.

ATX Power Supply getting too warm and a voltage drop from the bridge rectifier which will kill your GPU is your main concern running in a hot PC case.

When your ATX Power Supply can't feed the beast what it wants, poof goes the GPU power circuit. Watch out for ATX Power Supplies with Eco Mode that keep the power supply fan off...you don't want that with a 3080 ti. (put the EVGA power supply in the trash)

Okay now people are getting scared off only it's me.

I've never heard of this. My old GPU (definitely nothing high end though), however, did die shortly (between a few months to half a year?) after I changed my PSU to my current EVGA one which does have a Eco mode and I do use it, and there were apparent burn marks near the GPU VRM. I sort of figured this was coincidence as the EVGA unit I got was apparently a really good one. I was also suffering the driver crashing issues that many Fermi GPUs were at the the time, which some others also even went to claim were leading to failing GPUs (whether this was true or not is something I can definitely not verify but it was something I took into consideration a sI was also suffering them and the fate of my GPU did end up being that).

I'm not even sure what made you mention this as I don't see mention of an EVGA PSU or a PSU with Eco mode, but it caught my easy-to-worry attention.

I have a theory why some GDDR6X in 3080 and 3090's is running hotter in some PC's and not others.

Start reading about PAM4 in GDDR6X memory, why are they running so hot with the fans cranked and the GPU isn't really even working hard?

Signal noise issue in the PAM4=heat. What's causing the Signal Noise issue in GDDR6X...

EVGA...justa theory. Eco Mode in EVGA power supplies was first advertised for low to mid range PC's...they put out 1000 watt plus power supplies with it now. Poor ole GDDR6X...

Oh, well my failed GPU was years ago before GDDR6X. It was a GTX 560 Ti, so I guess that wouldn't have been at play in my case?

might want to work on your case airflow

You may have a theory / thought, but so do flat earthers...

The high temps on the 3090 is the memory on the back with often zero airflow and unless you are mining, those temps do not get thst high really.

On a 3080 it's nearly always a lack of airflow in either the case or gpu fan speeds, again, not really an issue if you aren't mining.

As for evga psu's, the G2 and G3's (and accompanying P and T variants) are among the best psu's you can buy.

your temps seem a bit high to me.are you using a air cooler for cpu ? they can add
alot of heat inside your case.try removing your side panel see if temps improve.
you may need to rethink your cooling solution.

also use a aggressive fan curve on gpu have fans ramp up at a low temp its easier
to keep a card cool than cool it down

na AIO it is actually pretty cool during winter idle @40C gaming around 60C GPU can be @ 70-75 without tweaking much and i believe for hotspot and such it never goes near 85.

Might aswell mention this During summer it can get as high as 30-35 lol i think my case is pretty good a lot of room to spare Lian li dynamic not the XL nor the mini atx i can possibly put 2 more fans at the bottom going for intake.

The fans i have is exhaust at the top intake on the sides im still learning how to undervolt struggling so far lol as for fan curve i set it on auto so not sure how fast it goes while gaming

I may need to buy a USB type wifi to free the space on the bottom so i can install 2 more fans intake i cant ethernet as its literally impossible without drilling a hole as its not my house

Google "EVGA 1600 T2 Blew Up". Eco mode on a 1600 watt PSU..lol. Lots of Google links on "Blown Up"...EVGA power supplies.

Killin those 3080 ti's..

Interesting. I have a slightly different setup. I want to preface this by saying I'm not an expert and not trying to tell people how to suck eggs.

To me the biggest issue with cooling a PC is you effectively have 2 heaters inside the case, the CPU and the the GPU. Right next to each other. I figured the best way to keep everything cool was to remove one of those heat sources from inside the case and at the same time have high airflow. That is why I went with an AIO.

The heat exchanger is mounted to the front of my case and I have 3 push fans and 3 pull fans extracting air through the heat exchanger out the front of my case. Effectively removing that heat source from the case as the air flow is from inside to out.

I also have 3 large in fans. 2 at the top and 1 at the back. It seems to be working well. I will still tweak a few things but for now I'm happy. I'm not the sort of person who is prepared to sacrifice cooling performance for low maintenance so I run no filters and clean my hardware regularly. The air flow I have is significant.

Just thought this might go some way to explaining my results.

i actually opened my glass panel so some heat will escape directly but at the same time i use Icue software i set my exhaust to zero rpm while non gaming but ye i really want to put my spare 120 mm fan to the back as an exhaust but it looks like it does not fit lol i dont have any 80mm ones to test if that will be better
