Hi guys,
I've been having a problem that's been bothering me for a long time, and I don't know if this is normal behavior from the graphics card or if something is wrong.
My graphics card's temperature usually ranges from 50 to 55 degrees Celsius when idle and under light use, given that I live in Egypt and the temperatures here are quite high.
The problem specifically appears as soon as I start playing some games. The temperature suddenly rises to 80 degrees Celsius for a few moments before the fans kick in. The temperature then drops to 75, then 70, then 65 degrees Celsius, and the fan speeds also drop, but everything is fine.
My question is, is this normal behavior for most graphics cards, or is there a problem with my card?
My system specs are as follows:

GPU: ASUS DUAL RTX 4070
CPU: Core I5-11400
Mobo: ASUS ROG Strix B560 G-Gaming WiFi
Case: Cooler Master MasterCase H500 Mid-Tower Case {Opened Case}
PSU: Antec New Eco 850W Gold

I just want to know if all NVIDIA cards behave this way, given that I've owned an AMD card in the past and never noticed this problem.

It's expected that the fans keep spinning when you set a software custom fan curve in MSI Afterburner since it disables the 0 RPM mode (the software takes over the BIOS fan control). But you can set it so the fans spin very slowly at low temp so you don't hear them.

If you still want the 0 RPM mode to be enabled, ckeck the "use firmware control mode" box and set a curve with that (don't use more than three nodes on the firmware curve or you might get an error message. To delete a node, click on it and press the delete key on your keyboard). The firmware control sets the curve directly to the card's BIOS and generally doesn't disable the silent mode.

There were a couple of variants of the H500, which one do you have? Mesh or non-meshed? If the temps for your GPU drop as soon as you remove the front fascia, then the problem is your case's airflow.

Looking at your specs, is the RTX 4070 an upgrade? If so, what GPU were you working with prior? If my assumption is correct that you swapped GPU's, did you run DDU prior to the GPU swap?

You should also look into undervotling your GPU.

Hello, thank you very much for your interest.
Sorry for not stating this clearly.
Yes, I have done a clean reinstall of Windows, and more than once.
My PC Case is opened all the time.
I also lowered the voltage, and things are fine under pressure.
However, the problem occurs during the first few seconds of running some games, when the fans are idle.
They suddenly run at 80% for a few seconds at the start of the game, then the temperature cools down and the fan speeds also decrease.
Is this a normal scenario, or is this a problem with graphics cards that have only two fans?
 
I havent had an Nvidia card in ages so i don't know if the driver has this option, if not use MSI afterburner or even better FanControl and set the fans to spin sooner than the default setting the card has.
This seems like a simple case of a very quiet fan curve in a hot region, so the fans are slow to respond to the card heating up. You may also want to clean the dust regularly so they don't get stuck.
 
Seems normal to me.
When the gpu needs to work harder, as in a game, it generates heat.
This will cause the cooling fans to spin up.
But, the cooling effect is not instant so both the fans and temperature will be elevated for a while.
By default, a gpu will have a target temperature, and 80c. seems to be a common one.
Not to worry.
 
Your card is probably set with a silent mode BIOS by default. My MSI 4080 is like that. If I don't have MSI Afterburner running with a custom fan curve, the fans stay idle until the card reaches 60c, then start spinning.

Depending on how the default fan curve is set in the BIOS and how fast it reacts to the temperature increase, it's totally possible that your card reaches 85c for a short while before going down to a more reasonable temperature, time for the fans to kick in and cool it down. I don't see any problem with that, but if you don't want it to behave like this, you can use MSI Afterburner to set a more aggressive fan curve ("fan" tab in settings), as suggested in a previous comment.
 
I really appreciate your help guys, also sorry for my late response or any language mistakes.

Your response has relieved me of a lot. I'm just not used to this behavior from NVIDIA or AMD cards.
Max temperature for the card is 90C so really nothing to worry about. https://www.nvidia.com/en-us/geforce/graphics-cards/40-series/rtx-4070-family/
Thanks for clarifying. The strange thing that it was 84C for all Ada Lovelace Cards, Or maybe i`m wrong, don`t really know.

Yes, I think that's the current situation.
I already using MSI Afterburner for undervolting, but the problem is my fans never stop when setting a fan curve, even after temperature drops to 35C, and i have searched for solutions everywhere, but no use.
Tried ASUS Tweak III, and no use either.
As for the BIOS Switch, It is already on the "P" Mode.

Thanks a lot for your help, I actually tried that, to make the fans spin as soon as it reaches 40C instead of waiting it reach to 60C, and suddenly jump to 80C because it was idle, but the problem is my fans never stop as soon as i tried to adjust it with Fan Curve, and i have tried every settings, but useless.
I don`t want to jeopardize it`s life span.
 
You are worrying too much. That temperature even if it's some sort of anamoly is perfectly fine since I have experience dealing with such cards reaching 80s regularly and never causing any issues.

Many thanks, I decided to enable Fan Curve whenever I wanted to start a new game, this way I ensure that the fans behave more rationally before entering the game and surprising the GPU with an overload, and after finishing playing, I will disable it again.
Is this sound a good thinking?
 
That’s actually pretty normal for modern NVIDIA GPUs, especially in warmer climates! Most graphics cards like your ASUS DUAL RTX 4070 keep the fans off or spinning very slowly when idle or under light use, so it’s common to see a quick temp spike to around 80°C the moment you launch a game.
Once the GPU hits a certain threshold (usually between 60-80°C), the fans ramp up, and temps drop back down to a stable range (65-75°C) during gameplay. If your temps stabilize below 80°C during gaming and you’re not seeing crashes or throttling, there’s nothing to worry about.
If you want to be extra cautious, you can adjust the fan curve using Afterburner or similar software to have the fans start a little earlier.

yeah I agree with the under volt the GPU I was having that issue when I start just about anything but cleaning the card its self often helps the GPU to handle the heating issue... Man I have been saying this allot lately thermal pads on the mosfits and replacing the thermal paste on the processor.... That often enough solves most of the overheating issues... Some of the newer drivers can over work the GPU so sometimes we have to add on pads to the locations that we didn't need to before... I noticed a difference between CSM to Uefi mode, If you have a secondary PC that has a CSM if you are using Uefi I switch the cards and put it in the CSM system to see how it reacts and also put afterburner in do some test to see if its at a different voltage... Ambient heat will affect things like computers tv's ect... But shouldn't cause too much of a concern... Make sure you have at least one out take fan in the PC and some intake fans... Label of the fan will indicate what direction the air flow is moving or the wires at the back of the fan shows the air flow blowing away from the unit not sucking it in.... Also not having it on carpet is best on a flat surface in a well ventilated room... Worst case if the air flow is not strong enough to keep it cool... Place a fan in a spot outside of the case directing air threw the vents.... I live in a more cooler climate but the summers still cause an effect for the PC...
