Hey everyone! I've just put together my first gaming PC and it seems to be running fine overall. However, I've noticed that my fans ramp up to high speeds and become quite loud during light tasks, like starting Windows or installing software. After about 10 to 15 seconds, they slow down again. My CPU temperatures are around 35°C in the BIOS and idle between 45°C and 50°C in Windows, occasionally hitting 55°C when using basic programs like GCC or Thermalright Software. I'm using a Thermalright Phantom Spirit 120 Evo Vision cooler with TF7 thermal paste, applied in a pea-sized blob. For reference, my CPU is an AMD Ryzen 7800x3d and my motherboard is a Gigabyte Aorus X870E. Any advice on how to address this issue? Thanks!

55°C is definitely not too hot! You’re good as long as you’re nowhere near 100°C.
It sounds like your fan curves might be a bit too aggressive right now. You can adjust them in the BIOS to be less sensitive for lower temps.
Your temps are totally fine for a stock setup. You should consider tuning down your fan curve; hitting 45-50°C at idle is nothing to worry about. Just make sure you're comfortable with the noise level.
Idle temps aren't really important; focus on your load temps. As long as your CPU doesn't exceed around 88°C under load, you're good. The noise from your fans likely stems from how the heat exits the CPU, which tends to get hotter than other processors. It's crucial to tweak your fan curves accordingly since the 7800x3d runs hotter. I've shared more on this topic [here](https://www.reddit.com/r/buildapc/comments/1p1a92f/arctic_freezer_36_vs_tr_phantom_spirit_120_se_for/npoll5d/).
I'd recommend checking out a program called FanControl to set custom curves for your fans. I have mine set to kick in after the CPU hits 55°C for 3 seconds. You can also lower the idle speeds until the fans are barely noticeable.
Since you're just starting, try setting custom fan curves in BIOS. Determine the max noise level you can tolerate at lower temperatures and adjust the fan speed up to 80% until it reaches 80°C, then from 81°C to 93°C, ramp it up to 100%. And don’t forget to enable Expo in BIOS!
Just a heads up, make sure you removed the plastic film from your CPU cooler if it has one. I forgot once and ran into similar issues; it's a common mistake!
