My PC was built about five years ago with an Intel i7-10700K, RTX 3060 Ti, and 32GB of DDR4 memory. I mainly play games at 1440p, ranging from lightweight titles to demanding releases, and I often run replay-recording software so I can save clips afterward.
Over the past few months, the fans have started spinning noticeably faster during games. My replay recordings have also become choppy, even when recording at lower resolutions such as 900p or 720p. I understand that newer AAA games may eventually push this hardware, but I am seeing problems in games that have not changed much graphically.
Could this be bottlenecking, or is something else likely causing the performance drop? What troubleshooting should I try, such as checking temperatures, cleaning the system, or changing thermal paste? Should I start planning a new build, or can this hardware reasonably be brought back to its previous performance?

The recording issue may be separate from the game's performance. Check whether the recorder is using the RTX 3060 Ti's hardware encoder or putting the encoding load on the CPU. Also check disk usage, available space, recording drive health, and whether game and recording files are competing for the same drive. A driver, recorder update, Windows update, or background process can also cause dropped or uneven frames. Compare the recorder's dropped-frame count with GPU and CPU usage while recording.
Before changing parts, verify whether the limitation is the CPU, GPU, memory, storage, or temperatures. Use an overlay or logging tool during a game session: GPU usage near 100% points toward the graphics card, while a fully loaded CPU with low GPU usage suggests a CPU limitation. High temperatures combined with reduced clock speeds indicate throttling. Four 8GB memory modules are usually fine, but check that dual-channel operation and the intended memory speed are still enabled in the BIOS.
The louder fans are the first thing I would investigate. Hardware does not normally become dramatically slower just because it is five years old, but dust buildup, a clogged heatsink, a failing fan, or dried thermal paste can cause higher temperatures and throttling. Log CPU and GPU temperatures, clock speeds, utilization, and hotspot temperatures with a hardware monitor while reproducing the problem. Clean the filters, heatsinks, and fans, then consider repasting the CPU cooler if temperatures are clearly higher than they used to be.
I have checked temperatures before without noticing anything unusual, but I will monitor them again while gaming and recording. If the CPU is running hot, I will clean it and look into replacing the thermal paste.
A five-year-old midrange system should still be perfectly usable, especially for many 1440p games, so I would not assume you need a new build yet. Game patches, driver changes, operating-system updates, background applications, and higher resource demands can gradually alter performance even when the graphics look similar. Check for recent software changes, reset any overly aggressive game or recorder settings, update or clean-install the GPU driver, and compare performance with recording completely disabled.
I tested both GPU and CPU encoding, and the choppy recordings happened with both settings. I will still check disk activity and the recorder's dropped-frame statistics while monitoring the system.
