I recently upgraded my PC by installing a Ryzen 5 5600x and a used 1080 Ti, replacing my old Ryzen 5 5500 and GTX 1080. Ever since the upgrade, both components are overheating while gaming. The 1080 Ti runs at 100% usage and quickly reaches 84°C, even dropping to 70% usage doesn't prevent it from hitting that max temperature. I suspect that the high heat from the GPU, combined with poor ventilation in my budget case, is causing my CPU temperatures to spike as well. What could be the causes of this overheating, and what fixes can I try?

Have you considered undervolting both your CPU and GPU? It can help lower their temperatures significantly. I undervolt my Ryzen 5600X and it dropped my temps by about 10-15 degrees. For the GPU, it's worth checking out as well. It may help keep everything cooler.
Since your upgrade is relatively minor, improving airflow in your case could be a key fix. Adding more fans or even getting a better case might really help with cooling.
You’ve upgraded to hardware where the 1080 Ti can finally operate at full capacity, which is good, but heat can become a problem. Poor ventilation or dust build-up might also be causing those high temps. Have you cleaned your heatsinks or refreshed the thermal paste? Also, consider posting pics of your setup for better feedback!
One immediate solution is to get a better CPU cooler. You’ll definitely want something more efficient to handle the new load from your 5600x.
I totally agree! Ordered a new cooler after doing some research myself.
The 1080 Ti is built to hit 84°C, which is its thermal limit. So as long as your CPU temperatures are fine, you might not have to worry too much. Your stock cooler might not be sufficient for the 5600x, though, so investing in a good CPU cooler could help a lot.
I did just clean my CPU cooler and replaced the thermal paste. I’ve also taken off the glass panel for better airflow, and I plan to add more case fans, as my setup initially only had one exhaust fan.
