I just learned that I can set different temperature sources for my PC case fans, like CPU, GPU, or motherboard temps. I did some research but couldn't find a clear answer. Here are my system specs:
* Case: Corsair 275R Airflow
* CPU: AMD Ryzen 7 5700X
* GPU: RTX 5070 FE
* Motherboard: Asus Tuf Gaming X570 Plus
* Fan configuration: 3 front intakes, 2 top exhausts, 1 rear exhaust
I primarily use my PC for gaming and occasionally for video/audio editing. I'm trying to figure out whether to set the top-rear exhaust fan based on CPU, GPU, or motherboard temperature, and if I should consider using one of the front intakes for the CPU. Any tips would be greatly appreciated since I'm not very knowledgeable about this!

Honestly, it doesn’t make a huge difference. The main thing is to optimize your fan curve for the best noise-to-cooling ratio. You can play around with settings to see what works best for you, depending on your specific setup and usage patterns.
I recommend trying out the app Fan Control to manage your fan speeds. I usually run some tests with OCCT to figure out the best fan curves for my CPU and GPU. If you don't want to do all that testing, you can set your GPU as the main temperature source for your fans and keep a close eye on your CPU's minimum fan speed to make sure it stays cool.
I have a CPU cooler that reads CPU temps, but I think your idea of using the GPU temp for fan control makes sense since it tends to get hotter when gaming. Speaking of which, what’s a good minimum temperature to aim for with fan speeds?
