Safe Temperature & Calculation Time for GPU rendering

[sd70]

Hello

My GPU is Gigabyte Geforce GTX 1070 8GB and I want to use it for animation rendering. I have two questions.

1. What is maximum safe temperature (°C) for this GPU? Is 60 -70 °C okay?
2. What is safe rendering time using GPU? Can I use my GPU in 100% load for hours or even days without worrying about damaging it?

Thanks

70°C on the chip is no problem, even in the long run. Above 90°C should be avoided though and over 100°C the risk increases quite a lot.
In general the life expectancy of electronics reduces the higher the temperature, but 70°C is not a problem.
However, this only holds true as long as the cooling is working correctly and no local overheating happens.
The design of the case and cards as well as the way the cabeling is done needs to make sure that adequat cooling is possible.
If the cooling is done well and reliably you can run your hardware at full load for as long as you want.

Thanks, So If I could keep temperature below 70C, I don’t need to be concerned about rendering time, right?

+1 to what Srek said. I just want to add a suggestion. Avoid high oc profiles of your gpu. It’s better to run at stock speeds and voltages. Pascal gpus are quite cool while rendering.

I have a single 1070 (asus strix oc) which boosts at 2017MHz, and during rendering the temperature settles at ~60°C and stays there for as long as it’s needed to finish the rendering. I use Cycles gpu for rendering.

thanks FatherN.

This is my workstation:

Motherboard: GIGABYTE GA-Z170X-UD3
CPU: Core i7 6700K
GPU: GeForce GTX 1070 G1 Gaming 8GB
RAM: GSkill RipjawsV 2×8GB=16GB DDR4 3200MHz CL15
SSD: Samsung 850 Evo SSD Drive - 250GB
PSU: Cooler Master B700 ver.2
Case: DeepCool Dukase Mid-Tower
CPU Cooler: Green Glacier GLC240A (Liquid Cooler)

A friend told me PSU may cause problems in the future. Is that right?

Well, it depends. It’s a “cheap” CoolerMaster. Nothing wrong with that, but you could do a lot better with the system you have and is quite decent. Let me put this way. It’s not a balanced option. And a cheap psu like this one certainly won’t have the best quality parts inside and this increases the risk. If it currently runs without problems, keep it for now, and upgrade to something more robust when you can. Especially if you decide to add a 2nd gpu for rendering in the future.

Thanks again. I’ll definitely upgrade my PSU in the future.
