Question GPU Temps reach 80C for less than 5 seconds, Is this normal?

[AMR2512]

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.

Welcome to the forums, newcomer!

Case: Cooler Master MasterCase H500 Mid-Tower Case {Opened Case}
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.

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/

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.
