My PNY RTX 5060 Ti 16GB boosts to about 2880 MHz at 1.075V during heavy loads. With the stock dual-fan cooler, it reaches roughly 80°C on the core and 107°C at the hotspot while the fans run around 2600 RPM, which is much louder than I would like. Larger triple-slot cards can apparently sustain similar clocks more comfortably, so I suspect the cooler is being pushed beyond its efficient range rather than the GPU being defective. I am considering using MSI Afterburner to cap the card around 2625 MHz and undervolt it. Should I start around 900–925 mV, or try a different voltage? How much temperature and noise reduction can I realistically expect, and would the performance loss be noticeable? Also, does the approximately 27°C core-to-hotspot difference point to a mounting or thermal-paste problem, or can it be explained by the high voltage and compact cooler?

A modest underclock is probably the sensible solution here. Chasing the maximum boost clock on a small dual-fan cooler may only buy a couple of frames while creating much more heat and noise. If undervolting brings the hotspot and fan speed down without crashes or visual artifacts, the small performance tradeoff is usually worthwhile. However, if the hotspot remains close to its thermal limit after tuning, I would treat that as a possible cooler-contact problem rather than simply accepting it as normal.
Undervolting should definitely reduce heat, but a 107°C hotspot alongside an 80°C core is a fairly large delta, especially with the fans already running hard. It can indicate uneven cooler contact, mounting pressure, or an issue with the thermal interface material. If the card is still under warranty, contacting the seller or manufacturer before taking it apart is the safer route. If it is serviced, the die needs proper paste while the surrounding components need the correct pads or putty thickness; using the wrong material can make contact worse.
Start by choosing the temperature and noise level you actually want, then find the highest stable clock at that voltage. Around 900–975 mV is a reasonable range to test for this kind of balance. Set a point on the voltage/frequency curve, apply it, and run several demanding games or benchmarks rather than assuming one setting will work everywhere. A small reduction in clock speed may have little real-world impact while substantially reducing power and fan noise.
That makes sense. I’ll focus on getting the noise under control first and then work upward until I find a stable frequency.
I’m mainly trying to cool the card down, not gain more performance. I’ll compare stock settings with a quieter 2625 MHz profile and check whether the hotspot delta improves.
