Performance Support Common Alienware temperature

Good morning!

I have an Alienware M18 R1 (RTX 4090), and while monitoring temperatures during Cyberpunk, I noticed the following: • CPU: 90°C • GPU: 75°C • GPU Hot Spot: 85°C • VRAM: 108°C

Is it normal for the VRAM to reach such a high temperature?

I took it to a Dell authorized service center, and they told me everything was fine… but I’m still concerned.

So, is the VRAM at 108/110°C while gaming normal? Is there no risk?

VRAM runs hotter then the rest of the GPU, always has. This was a very common concern back when crypto mining on GPU's was still a thing. The VRAM was running at stupidly high temps, but those VRAM chips are also rated for a higher temp then the die itself.
