Ideal: GPU (+VRAM) Temp == Ambient Temp

Not exactly practical though.

Like Lexiko mentioned, there is no ideal GPU temp.  While mining, temperature doesn't affect hashing speed, unless it is extremely high like 100 Celsius or more.  As a general rule of thumb, you risk damaging components in the long term if running the GPU at a temperature constantly above 80 Celsius.

From what I understand you want to keep them below 75' C any higher and you can suffer damage to your video card. You may not damage it in the near term with higher temps than this but you will probably shorten the life span of the video card .

I've read somewhere, that every 10°C above 80°C will decrease your graphic cards lifetime twice.

So if it 10 years normally:
- 90°C will make your VGA's lifetime 5 years
- 100°C — 2 year and 6 months
- 110°C — 1 year and 3 months
- 120°C — 6.5 months
- etc.

you cant look on the gpu temp and calculate how long you whole card will work.
Remember, cpu and gpu are nearly imortal. There are other parts that will fail first.

Back in HD4870 times, there were cooling solutions which garanted a gpu temp undr 60°C, but many cards died within the first week. Why? Vram overheaded....
