Hey everyone! I've been having some concerns about the idle temperatures of my CPU. I recently mounted and applied thermal paste (I used MX6 this time) on my Peerless Assassin cooler. Right now, my CPU is sitting at around 75°C at idle, but it can spike up to 90°C without hesitation if no adjustments are made. I understand that the Ryzen CPUs can go up to 94°C safely, but I can't shake the feeling that there's something wrong with my setup. I'm also worried that my temperatures might be high because of the room temperature (27°C) since I live in a Mediterranean climate. I've posted a screenshot of my current temperatures for reference. Should I consider returning my cooler? For context, I have a Ryzen 7700X, an ASUS TUF B650 motherboard, and I'm using this cooler in a case with two intake fans and one exhaust fan.

Just remember, your PC's temps will depend a lot on the room temperature. Is there enough airflow in the room? Are you recycling hot air? Double-check the airflow in your case, too. How are your fans configured?
It sounds like you might want to check core temperatures using HWINFO instead of relying on the Tctl/Tdie readings; that could give you a clearer picture of what’s happening. What do the core temps look like?
Your idle temperatures do seem a bit on the high side. Make sure your fans are mounted correctly. If they're not functioning properly or are oriented wrong, it could be contributing to the heat issues.
Both fans are intake directed into the heatsinks, similar to the setup in this article.
As long as you’re not exceeding those maximum temperatures, you should be fine. That said, temps around 75°C at idle are definitely warm for a Peerless Assassin. You could try enabling Eco Mode in your BIOS to help reduce heat and fan noise—it simulates lower power CPUs which can decrease your temps and extend the life of your system.
Thanks! I know I might be overthinking it a bit, but I'm just looking for the right info.
Honestly, idle temps aren't everything. Have you checked how it performs under load? 75.4°C doesn’t sound overly concerning to me, just don’t let it get crazy higher during intensive tasks.
When gaming, it spikes between 70-90°C now with the limits I set.
Here's the complete screenshot I posted earlier for reference.
