My PNY RTX 5060 Ti 16GB boosts to around 2880 MHz at 1.075V during heavy loads. With the stock dual-fan cooler, it reaches about 80°C on the core and 107°C on the hotspot while the fans run near 2600 RPM, which is extremely loud. I'm considering using MSI Afterburner to cap the card around 2625 MHz and undervolt it. Would starting around 900–925 mV be reasonable, and how much performance, temperature, and noise reduction could I expect? Also, is the roughly 27°C core-to-hotspot difference normal for this cooler and voltage, or could it indicate poor mounting pressure or uneven thermal paste?

Start by setting a reasonable temperature and noise target, then tune the frequency around that instead of chasing a specific voltage. Around 900–975 mV is a sensible range to test for a balanced profile, but every GPU is different. Lower the voltage gradually, test stability in several games, and keep the highest stable clock rather than assuming 2625 MHz will work at one exact voltage.
The card’s stock boost behavior is probably giving you very little real-world performance for a lot more power. A modest undervolt and clock cap may cost only a small amount of FPS while substantially improving acoustics. Test with a repeatable game or benchmark, watch for driver crashes or visual artifacts, and save the profile only after several hours of stable gameplay.
A hotspot near the thermal limit should not be ignored, especially with such a wide core-to-hotspot gap. Undervolting may mask some of the problem, but it won’t correct bad contact. If the hotspot remains close to the limit after tuning, contact the seller or manufacturer before attempting a cooler remount.
Undervolting should reduce power draw, heat, and fan speed, but a 107°C hotspot with an 80°C core is a fairly large delta while the fans are already working hard. That can point to uneven cooler contact, mounting pressure, or a poor thermal interface rather than just an aggressive boost setting. If the card is still under warranty, an RMA or replacement is safer than opening it. If not, inspecting the mounting and replacing the thermal interface may help, though disassembly can affect warranty coverage.

That makes sense. I’ll prioritize getting the temperature and fan noise under control, then find the highest stable clock at the lowest practical voltage.
