Hello Guys!
I have a Gigabyte Gtx 1660 Super OC 6g dual fan
When I stress test the gpu in Heaven 4.0 temps reach 80°C
Note that I did not turn on case fans. My system specs are:
Cpu Ryzen 3 3300x
8gb of Ram 3000mhz
Case similiar to nzxt h510, with 3 intakes and one exhaust
Mob Msi b450m a pro Max
Psu 500w
I have an old monitor that runs at 1366 x 768 Resolution
Gpu idles at 47-50 C
Is there anyone who has the same gpu that can guide me to the sweet spot of undervolting it? Thank you.
 
Solution
Graphics cards use 80c. as a thermal target.
They run up the performance of the card as best as they can while keeping to 80c. temperature.
That means, usually, running the cooling fans faster.
There are apps to manage this. You can lower noise but at the cost of gpu performance.
Graphics cards do run hot, but they are designed for it.
By omitting front intakes, you are likely reducing the performance of your graphics card.
Your case supports two 140mm front intakes.
140mm fans will draw in more cooling air at lower rpm than other options.
What is the problem you are trying to solve?
80c. is a normal operating temperature for a loaded graphics card.

Then, also, your cpu and gpu need fresh air for their coolers to do their job.
You must install at least some front intake to your case.

80c is safe and why would you stress test with your case fans off? Of course things will get hot. What is the temperature when your case fans are on and you stress test?

Temps with case fans on are the same 80-81C. It doesn't help in bringing down the temps of the gpu unlike the cpu.

Am trying to run at lower voltages in order to improve thermals and reduce noise.

Thank you for your reply sir!
You probably didn't get me
I already have 3 intakes and one exhaust and even running them at full speed, gpu thermals do not improve
the question is, is it safe to run at 80C and i should not be worried?
 
I don't think I explained by theory adequately.
My point is that the gpu is going to normally try to run the gpu at 80c. under load regardless of your setup.
The gpu microcode knows that 80c. is ok and will ramp up the performance until it reaches that 80c. target.
With front fans, you will still run at 80c., but your performance will be better.
