Is it typical for a GPU to reach up to 1600 MHz while another stays under 1400 and a third operates at 60°C, especially with the top one running at 80%? Below shows faster performance and lower temperatures. Could there be a solution to this issue?

Ys Kuzi :
3 fans to the fornt of the case blowing in one exhaust to the back and two fans on top blowing out
try repositioning the 2 exaust fans on the top as intakes and then repositioning the intake fans as exaust fans. That way you have cold air blowing directly on the top of the GPU. Measure the temp and report bnack to me.

It seems you're likely in the incorrect section. Could you share more details about the GPUs you're using? If you haven't overclocked, the boost speeds are normal. It appears there might be an overheating issue, possibly from inadequate ventilation. The bottom card is releasing hot air upward, which raises the top card and causes throttling. Have you verified that both GPU fans are running? Increasing case and GPU fan speed could help dissipate heat better, but if the problem persists, there may be trapped hot air near the GPU. Could you describe your case and fan configuration? Pictures would be very useful.

They're running a little too fast, but it's not overheating because both cards are using the same high fan speed. I don't know how to upload pictures.

Based on my understanding, because the cards are positioned very near each other, one card will receive better airflow than the other, particularly if it's placed close to the bottom GPU. You might consider boosting the fan speed on the top card and checking if the temperature decreases. Heat could also be affecting the card's performance.

After one card away, the highest position is near the CPU.
The fan profile increases to 100% at 70°C.
Two fans blow into the cards while one draws air out.

Find the exact position of that fan in your computer.

Three fans are positioned at the front of the case, directing air through one exhaust to the rear, while two additional fans are mounted on top to expel air.
