CPU and GPU Temperatures

[Hi P]

The questions are for both the CPU and the GPU:

 

1.- What's the average temperature when idle / low load? (web browsing, etc)

 

2.- Why most GPU fans do not spin until the temps are around 50 centigrades?

 

3.- Which temperature should they NOT go over when under heavy load? (gaming on ultra, rendering, etc)

 

 

A bit out of topic but I was wondering:

 

4.- What are the drawbacks to set the GPU Power Target to 90% besides 100%?

 

5.- Aside from temperatures, what other settings help to extend their life span?

1. It depends. I usually get around 40-50c on my B85 file server with a crappy cooler.

2. Because of noise. You really don't need the fans spinning and creating noise until the heat starts rising.

3. I would say 90c max. Thermal throttling usually begins at 85c so try to stay around 80c if you can. That way there's no thermal throttling and the components are at a good temperature. There's a reason CPUs thermal throttle.

 

4. Your GPU will not perform as well (only by a bit) since it is drawing less power.

5.  I'd recommend to not keep them at 100% load most of the time and I would also follow @fasauceome's advice on life span.

There's no way of knowing but it's gonna be low

No point. If the stuff stays cool without fans they can stay off and quiet

Above 90 degrees for an extended period is bad news

less performance, but slightly higher efficiency (and less noise from reduced cooling requirements)

A bracket to reduce GPU sag and proper case ventilation

[Happycowdance]

1. depends on your cooler but between 40-60 

2. depends on your fan curve

3. 90-95

4. your gpu wont have as high of a clockspeed and be slightly less powerfull

5. not using it as much, not dropping it, not overvolting it, not using a crap powersupply, not spilling water on it, bracket to reduce sag etc

So 45 centigrades isn't considered hot for a GPU?

 

I should get a bracket, my case didn't had one, does reducing clock speed also reduce their stress?

Only for really large graphics cards. Which one do you use?

yes because clock speed is directly proportional to GPU power

Thank you, I'll run some tests to see if reducing the clock speed affects my workflow

CPU 35-50C, GPU 40-50C, but these do depend on cooler and fan settings.

Centigrades? You mean Celcius. And its firmware thing. Mainly on newer cards. Mine doesn't allow fan to go lower than 30%.

85-90C for CPU, 95C for GPU. These are max you should see under stress test. For actual load temps, cooler and fan settings will be a thing. Like my CPU goes up to 74C while rendering, GPU goes to 82C while gaming.
