RTX 3090 memory junction temprature

[TIG]

I have i9, 9900K, 32GB, RTX 3090 Asus Strix. While gaming at 4K ultra settings, I noticed from GPU-Z, that my gpu memory junction temparure above 85 deg from games like Control, Ghost Recon Breakpoint, The Division 2. It even touches 90deg for Red Dead Redemption 2 at ultra settings. Whereas as games like Call of duty Cold War (74 deg), Warzone (72 deg) and Battlefield V (80 deg). In all above mentioned games, the gpu core temprature ranges between 65 to 71 deg.

My question: Do you think, the gpu need Thermal Pad change?
How about applying only aluminum heatsink on the back only?
Thanks

Under approx 100*C for the Memory Junction Temp is fine.

At least you don't have a 3090 FE card which had issues where it was sometimes hitting 110*C under full loads or when mining.

Can't comment on thermal pads or if those temps are worrying, but you can get a box of assorted mini heatsinks and a roll of thermal tape for like $30 on Amazon. With specs like that it is clear you want the best of the best and money is clearly no object for you, so why not?

I think 95c is TJmax for GDDR6X, so try to keep it under that.

Why not just place a case fan or two under your GPU at the bottom of your case? I have this for when my GPU gets hot, they then kick in. Other than that they stay idle. A lot of peoplewill slap an AIO on their CPU, and leave a stock fan in their case and then wonder why their GPU overheats even when the fans are on full chat. Your case needs good circulation too.
I have an MSI 3090 Gaming X Trio and don't see temperatures anywhere near that in any game or when rendering in Blender either.

You may have already done this of course.

He is asking about memory temperature, your card can be run under 70c and memory still hit over 90c.

You are totally fine, throttling can potentially oc our when it goes beyond 110c and the chips actual safe operating temp will be a good 20-30c above that.

There is no need to woot about it, changing out the thermal pads can help just make sure you go for something good.

If you are really worried about it (no reason to be) you could place a fan blowing directly over the back plate.

Depending on your case (like an 011 with certain vertical mount brackets) if you have the gpu vertically mounted, potentially puling it 1 slot further out from the gpu so air can more easily move around it can drop temps a couple of degrees.

Thank all for your feedback.
I think I will go for the following:
Placing and distributing aluminum heatsink chips on the back plate and put a small fan on the heatsink.

In this case, I have another question:
If I have to keep a fan on the heatsink chips, which direction air blow should be? Away from the heatsink or the reverse?!!
Thank you all once again

85°C is more then fine. Had about 105°C on my strix because of bad airflow behind while vertical mounted. Went total overkill placed a waterblock on back with heatpipes and 2x 140mm fans below :/

As I said, there is zero need to worry, I'm running 2 3090 strix right now with a 9900k (mining on them not in sli) and as I said, your temps are well within accebtable limits, hell I can even game on it while mining and temps stay in the safe range.

I wouldn't go ruining the back plate myself when any of the fixes I mentioned will be just as effective.

Just because you think it's too hot doesn't mean it actually is.

OK.

I'm aware of this. But if ANY temperatures are a concern, then increasing airflow will lower that temperature. There's no point in damaging a backplate or removing it to reduce heating of a localised area if there is limited airflow inside the case in the first place?

In RTX 3090, there are 12 VRAMs placed at the back and most these VRAMs that are subjected to overheating. Airflow alone might not provide efficient solution.
Considering the heatsink solution, nothing will disturb the gpu back plate at all. All the heatsink chips are removable easily at any time.

from what ive seen the founders edition vram runs at 100-110c under full load so compared to that your better off.my evga 3090 ftw3 ultra runs 75-80c under full load so compared to that your
a little high but nothing to worry about.if you have a cpu air cooler your going to run a little
hotter on your gpu try venting your case better,turn up case fans,and if you have a glass front
case well your just plain screwed.

According to nvidia it is more like 105-110*C

So if it doesn't go above 90 then you should be fine. New thermal pads or backplate usually will never change this. All you can do is keep the PC and the cpu and gpu coolers as clean as possible over time and if feel the need, add more and/or better airflow to your Case. Ambient room temp can play a big role here as well.

I doubt it. modern AMD gpus since RX 200 series have had no issues running all day long at 95-99*C and that's with just gpu core temp in mind.

Sure I would do whatever I have to for me, to never had any gpu run any part of the gpu above 85*C at its highest peak. But again RTX 30 series was designed differently and CAN handle it. Previous NVIDIA gpus could never handle temps above 85-90*C, period
