GPU overheating after configuration change

Hello everyone :)
I tried to find an answer by browsing various forums on this topic, but nothing has been able to provide me with a solution. Here's my problem:

I just changed the motherboard, processor, and power supply of my computer.
I switched from an i5-3400 to an i7-10700k for the processor part.
I did not change the graphics card (a 1060 GTX 6GB) which is still good for my use.

Once the change was made, I immediately noticed a rise in temperature of the graphics card (+10/20°C) compared to the old configuration.

Yet nothing changed in terms of cooling; I have 2 fans and now a third one for the processor with a heatsink.

A question comes to my mind:
Could it be that my old processor was somewhat bottlenecking the graphics part, putting less demand on the GPU? (thus generating less heat) Switching to an 8-core processor is almost limitless in terms of resources used.

If that's not it, what could be the reason?

I read on another forum that it is recommended to reinstall the OS when changing hardware to take the new configuration into account. Is that true?

Thank you :)

Hello,
yes your processor limits your graphics card (the i5-3400 doesn't exist, but for processors in that range, that's the case)

yes it's better to reinstall the OS but it's more to avoid problems with existing drivers, it doesn't cause overheating.

as long as you're below 75°C the temperatures are fine, if it exceeds 85-90°C you need to take care of it (change the thermal paste in particular), between these two values just keep an eye on it.

Sorry, it's i5-7400 ^^
I'm waiting to get fiber so I can reset everything because I have a lot to reinstall, especially heavy games.

Good idea for the thermal paste, the card is almost 4 years old and given the scarcity of GPUs and the prices, I want to keep my card for a little longer, especially since the fans on the card are running more than before now. So, would a Thermal Grizzly (or another with thermal conductivity > 8) do the trick?

"Sorry, it's i5-7400 ^^".

For the old CPU or for the new one?

What cooler do you have (brand and model)?

The old CPU
so I'm switching from i5-7400 to i7-10700k

Regarding the cooler, it's a cool master hyper tx3 evo
I just bought thermal paste with a thermal conductivity of 8.9 (arctic silver 5) for the GPU, I will make the change and test afterwards

So I just changed the thermal paste, even though the old paste was dry, there's not much difference, the GPU goes up to 80°c and gets quite loud even (normal at this level) considering I was used to the silence haha.

So I'm wondering if the GPU can handle this pace knowing that I play at least 5 hours a day.

Are you sure you put in enough?

Yes,
that said my card in full play runs around 75-80 (at most)° which is correct according to what I've read, but what a racket!! a real blower.

I had never faced this before, I didn't reach these temperatures with the GPU, so with the new processor maybe I'm facing a GPU bottleneck? Because under load always in game my new processor is averaging around 12.5% usage on the 8 cores compared to 100% for the GPU. If that's the case, then the two solutions I have in mind are:
- either I change the GPU
- or I improve the case ventilation to at least decrease the temperature
Am I wrong?

No, that's it. Depending on your screen, you can limit it; for example, if your screen is 60Hz, there's no point in exceeding 60 fps.

For the CPU temperature, while the Cooler Master Hyper TX3 Evo was sufficient for the i5-7400 (TDP 65W), it becomes too inadequate for the i7-10700K which generates much more heat (TDP 125W). One needs to consider installing a more efficient cooling system.

No no, everything is fine with my processor, whether it's the old one or the new one,
it's my graphics card that's going crazy with the temperatures :)
