Constant temperature vs variable temperature (Graphics cards)

Recommended Posts

Posted · Original PosterOP

Guy, so I was reading something on some forum and saw that some people say constant 75 degree Celsius on a graphics cards is better than variable temps (ex:30-75-40-30-75). Is it true? Why?

what do you mean by 'variable' temps? You mean fan curves?

Sorta, just from standard contraction and expansion but your graphics card is designed for this, you will not likely notice the wear and tear, at what load and temp does the heat cause more wear and tear than the former I do not know, you would have to ask the engineers that designed your card. Again it will be so negligible it doesn't really matter.

There aren’t any variable temps. It’s eirher hot or not. Maybe if you are a chrome user or something. 

 

Dont see why it would ever be a concern to anyone.

No it's absolutely ridiculous. Higher temperatures cause thermal degradation and that's proven from 40 years of work with silicon in a high-end computational environment. Heat degrades everything anyway, so having a processor or GPU core heat up and then cool down is NOT a problem.

 

However, there IS a lot of merit to the idea of leaving a PC in the 'on' state and never shutting it down. It's proven if you constantly shut down a machine, on average and across several samples, the machines you switch on and off as opposed to those you just leave on, will die sooner. It's the same thing as turning on a light. You require an immensely high burst of voltage to light the filament as opposed to what's required to just keep it running. Eventually that strain becomes too much and that's why lightbulbs 'pop' when they die.

 

But constant temps are bad. I would rather my CPU not sit at 80*C all the time thank you. :P

I'm pretty sure he means constant temperature fluctuations, which can cause solder joints to crack if they are extreme enough, but this shouldn't happen under most circumstances. You'll be fine either way, as 75C isn't an overheating temperature.
