What is a good idle temperature for my GPU?

Question

I recently built a new gaming PC and I wanted to make sure that my GPU is running at optimal temperatures. I've been monitoring the temperature of my GPU while it's idle, but I'm not sure what a good idle temperature range should be.

My GPU is an NVIDIA GeForce RTX 4080, and I've noticed that the idle temperature hovers around to $C$ when I'm not running any graphically intensive applications. Is this a normal and safe temperature range for my GPU when it's idle?

I want to ensure that my GPU is not running too hot, even when it's not under heavy load, as I know that high temperatures can potentially reduce the lifespan of the component. On the other hand, I don't want to be overly concerned if these temperatures are within the expected range.

If anyone has experience with this particular GPU or similar models, I would greatly appreciate your input on what idle temperatures are considered normal and safe. Additionally, if there are any steps I should take to optimize the cooling of my GPU, please let me know.

Thank you in advance for your help!

A good idle temperature range for most GPUs is 30-50°C. Anything under 60°C is generally considered normal during idle conditions. Some key things to keep in mind:

Idle temperature can vary depending on factors like your GPU model, case airflow, ambient temperature, etc. What's important is the difference between idle temp and load temp.
Pay attention to sudden spikes or changes in idle temp rather than the specific number. A 20°C jump could indicate an airflow or fan issue.
Lower idle temperatures are better, but don't worry unless your GPU starts exceeding 60-70°C at idle or shows a drastic rise over its usual baseline temp.
Newer GPUs also tend to run slightly hotter than older ones, even at idle. This is because they have higher power draws and tighter transistor densities.

So in summary, 30-50°C is a reasonable target, but focus more on relative changes and load temps rather than chasing a particular idle number. Keep an eye out for unusual spikes!
