Is 38c temp hot for an idle GPU?

[stource]

I downloaded a program to monitor GPU temp and it says it's 38c when idle. Is that to hot or normal?

In some ways it depends on the GPU as some contain inbuilt fans and are designed to handle heat a little better than others.

The idle termperature is less impactful than the stressed temperature under load, so you really need to monitor the temperature typical whilst you are say playing games or otherwise utilising the GPU - then consider the relative durations spent under these circumstance.

A GPU idle for 4 hours is still going to be approximately impactful on the lifespan of the device than at double the workload for for 2 hours and this is not a linear relationship - the heat generated is proportional to the square of the voltage.

However, in ALL cases, heat generation will always be detrimental to the lifespan of the device. This is inevitable.

It's a good temp.

Lifespan is not based on how hot you use the card. But how you use the card. Long terms of sitting a whole night will reduce the life on it no matter.

So wrong.

Heat is exactly what degrades the components.

Using a card all night will generate more heat than not using it. This should be logical.

Booting a computer from cold and shutting down will do more damage as the chips on a lot of the components will expand and contract due to heating up and cooling down again.

Basically it's better to leave your computer on all day if you wanna come and go from it, Shutting down for 30 mins then booting again is worse for your hardware.

Sooo it's a good thing to just let my PC sleep and not have to shut it down every night? We've always just told our PCs in my household to sleep anyway. I restart it at least once a week if I remember to do it.

I always shut down my PC

Components' circuit boards are designed to handle expansion (and by implication contraction) from the heating. Yes it will impact lifetime, but it's really negligible compared to the repeat charge and discharge of capacitors and the aforementioned heat effects when devices are under load.

It is fine.

Under 40 is normal. A little over 40 is acceptable too, depending on conditions and how the actual card is designed. Some for example don't actively cool unless they're actually active, and if they're in a smaller case (or heaven forbid, a laptop) in a warmer environment, they're going to get a bit heated even doing nothing. Because electricity and physics, innit.

Rule of thumb = 20 degrees above ambient APPROXIMATELY is normal. That's a really really loose APPROXIMATELY, as idle temps don't really matter unless they're glaringly and ridiculously out of whack.

The only "good thing" is to do whatever is convenient for you and how you use your PC. With modern hardware, sub-optimal power cycling impacts device lifespan so little you won't notice or care. Unless you just sit there mashing the reset button, in which case you will. Or if you're an enterprise trying to min-max thousands of pieces of expensive hardware...

Rule of thumb = don't turn it on/off more than 2 times a day, try and keep it to 1 or fewer. what's a few weeks overall of reduced device lifespan between friends, this isn't the 1990s where turning something off slightly too often risked the death of your entire family (and also, your computer)
