Why do people care so much about temps?

[DeadlyPilot]

It seems that people will do whatever it takes to keep CPU/GPU temps as low as possible without very much reason to do so. 

 

What specific reason makes you want to keep your temperatures as low as possible? Thanks!

Overclockability is more stable with lower temps, because when a GPU/CPU gets too hot, it crashes to prevent damage.

Higher temperature=Higher chance of failure

i dont want my computer to die

I rather not have miniature sauna in my room, but the temps of 980ti (arun 70c) dont worry me

The thing I don't understand is why people get upset when something runs hot, but is okay to run hot. Like People complain about AMD running hot, but they are engineered to allow for more temperature.

High temps mean throttling and throttling = bad especially in a game when your fps just tanks at the worst times

[Simon771]

Well because we feel more comfortable looking at HWMonitor saying that CPU and GPU are running under 50°C while on full load. Best feeling ever mate!

I went for water cooling, because it's more quiet, and I tried to get rid of the noise. It did help to some point, and my system is running now pretty quiet. Also temps are as mentioned above.

Lower temps will increase lifespan of your components usually. 

And ofc, we have more headroom for OCing.

Are there any tests that suggest higher temps reduce CPU/GPU lifespan?

Excess heat accelerates wear. Not significantly, but it does. Ideally, you'd want your processor running at the lowest temp possible, and at as consistent a temp possible. 

 

I don't think that most people think like that though. It's more, they want as much thermal headroom as possible to account for heavy overclocks and ambient temperature variations. Either that, or to brag about it and justify the cooler they totally didn't need.

It's theory based on physics. It's something that's sort of difficult to objectively test for small groups of people, as it would require a very large sample size to overcome the imprecise manufacturing process. Not to mention the time and staff hours it would take... Just imagine 5-10 guys trying to run a few hundred processors into the ground over the course of like 10 years...

So your 70c is 158 F... That's a hot ass room *Sarcasm*

 

It doesn't matter if you liquid cool your GPU/CPU. The temps will remain the same.

That's just how physics works.

Run an electronic device at 100C+ and it will die in minutes. Run it at 0C and it will last decades.

That's why electronic components are rated for certain temperatures.

 

You can take a look at all the reports of GPUs dying from back when people used them for bitcoin mining, running at 90C+ for months 24/7

 

Now there isnt much of a reason to cool your CPU to 60C instead of 80C, since 80C is perfectly fine, but its safer to have a larger margin in case of a heat spike from high ambient temps, a torture test like prime 95, or stuff like that.

Also bragging rights.

well 70c only in gpu, cpu and other are way cooler. And also now ill save money in heating of my room.

Longevity of the PC, more headroom for OCing, less chance of the PC thermal throttling. A variety of things.

A case study with an i7 930 overclocked under full load 24/7 running at ~80°C:

CPU thermal paste had to be replaced every 18 months.

The system still performs the same as it did on day 1.

 

A case study with an i7 3930K overclocked under full load 24/7 running at ~80°C:

CPU thermal paste had to be replaced every 18 months.

Thermal pads on motherboard decomposed and needed to be replaced after 42 months.

After replacement of thermal pads on motherboard the system performs the same as it did on day 1.

 

Running up to 80°C 24/7 is not usually a concern at all. Beyond that and there would be an increased frequency for water loop (if present) and thermal pad/paste maintenance. Degraded thermal interface materials may result in increased thermal throttling or instability over time, although a well maintained system should run just as it did when you got it.

If you run at 0°C without proper precautions you are at risk of condensation reducing lifespan to minutes though.
