Quick Answer

For OBS recording, the easiest CPU cooler upgrade is a quiet tower air cooler matched to your socket, such as a Deepcool AK620 (around R899) on AM5 or LGA1700. Recording adds sustained CPU load, so a dual-tower air cooler keeps the chip cool and quiet without the noise spikes that OBS mics pick up.

Why cooling matters for OBS specifically

OBS encoding (especially x264 software encode) loads the CPU hard and continuously. A weak cooler lets temps climb and fans scream, exactly the noise your recording mic captures. A R899 dual-tower cooler holds a Ryzen 7 at 70-80°C and lets fans run slow and quiet during recording.

Use hardware encoding to cut the heat

Switch OBS to NVENC (Nvidia GPU) or Quick Sync (Intel iGPU) encoding to offload the work from the CPU. That lowers CPU temps and noise further, so even a modest cooler stays quiet on camera.

Match the socket

Buy a cooler with your bracket (AM5 or LGA1700) included, and pick one with a quiet PWM fan you can tune to ramp slowly.

Set OBS to record to a separate fast drive from your game install; this keeps the encode and the game from competing for the same storage. Budget around R1,200 for a dual-tower cooler rated near 220W of cooling, which keeps the CPU and its fans well inside their quiet comfort zone during a long recording.

FAQ

Why does my CPU run hot and loud when recording in OBS?

Software (x264) encoding loads the CPU continuously, raising temps and fan speed. A better cooler plus switching OBS to NVENC or Quick Sync hardware encoding fixes both.

What cooler keeps OBS recording quiet?

A dual-tower air cooler like the Deepcool AK620 (around R899). It holds a Ryzen 7 at 70-80°C under recording load with the fan running slow and quiet.

Does hardware encoding reduce CPU heat?

Yes, significantly. Using NVENC or Quick Sync offloads encoding from the CPU to the GPU, lowering temps and fan noise during long recording sessions.

TIP

to NVENC or Quick Sync hardware encoding and pair it with a quiet dual-tower cooler; together they keep recording sessions cool and silent for your mic.
