Executing Ryzen 7 3700X under high performance conditions
I recently switched from Xbox after a decade and built my first PC. I'm facing some overheating problems with my CPU. My setup includes a 3700X with an H100i RGB Platinum, a Corsair Crystal 280x case, and a 5700X Red Devil. I've tried different fan arrangements—six 120mm fans total, two front for intake, two at the bottom for fresh air to the GPU, and two at the top as exhaust. Under heavy load, my GPU stays around 68°C while my CPU reaches about 85°C and throttles slightly. The Ryzen Master's auto-boost raises it to 4.4GHz but caps it at around 4GHz when needed. After experimenting, I connected the top fans to the radiator intake and kept the bottom exhausts, which helped keep CPU temps near 85°C. Now I’m considering switching all fans to intake, using the back grill for airflow, and seeing if that brings things down. I’ve read that a 240mm AIO fan should suffice for keeping the 3700X cool enough to avoid throttling. I also want to keep my GPU fans visible through the case glass but be flexible with their placement.
I possess the wraith prism, which I can throw to observe its behavior and evaluate its performance.
It seems you're suggesting the entire heat comes from the CPU cooler. You might consider directing some of that heat away from the CPU radiator to the back instead. Let me know if that makes sense.
Check if you're limiting power while playing or running tests. Suggest adjusting the manual voltage and considering overclocking.
At first I used two exhaust fans and four intake fans. Then I reversed their positions—swapping the bottom two to exhaust and the rad fans to intakes. It didn’t significantly affect the CPU temperature, but my GPU got hotter. Later I moved the bottom two to intake positions to bring fresh air to the GPU. The front fans also act as intakes. This setup with positive pressure from all fans helps push out the hot air from the back. Whether this is better than two dedicated exhaust fans isn’t clear yet.
The Corsair Crystal 280X comes with basic glass panels on the front and top, limiting airflow. There are small openings for ventilation on the sides to let cool air in and exhaust warm air out. If removing the side or top panel lowers your CPU temperature noticeably, it suggests poor airflow is the issue—possibly contributing to the problem.
