Performance is being reduced due to overheating.
Hello, I recently upgraded my CPU and motherboard—switching from an Intel i5 6400 to a Ryzen 7 2700X. The setup went smoothly during installation, but I encountered an issue: the CPU would throttle down to 0.6Ghz every five seconds when under heavy load, such as rendering 3D models with PBO and Core performance boost enabled. Temperatures reached around 85°C, which clearly triggered throttling. At that point, I turned on the H mode on the Prism cooler and adjusted the thermal paste, but it had no effect. Even adding two exhaust fans at the back and top of the case, or trying an open case setup, didn’t help. Eventually, I purchased a new cooler (Arctic Freezer 34 eSports DUO), which lowered the temperatures to around 72-78°C during heavy tasks—still within normal limits for me. Idle temps are about 30°C, as monitored via Ryzen Master, MSI Afterburner, and Aida64. The throttling remains a concern. I’ve tried overclocking by setting it to 4.025GHz at 1.35V in Ryzen Master and disabling PROCHOT, but these solutions feel risky. I’m open to advice on resolving this. Also, when I reinstalled Windows 10 after the upgrade, updated the AMD chipset drivers, and tested various power plans—everything was up to date, including the BIOS. No changes were made.
Have you tested it at regular speeds without manual or auto OC activated? Which motherboard are you using? Ensure you have equal or more inlets inside the case to keep a small positive air pressure.
You're confirming the CPU cooler is placed properly and the thermal paste is sufficient. The 2700X is working smoothly with the boxed cooler and the pre-applied paste.
I experimented with various settings - it didn't cause thermal throttling, which is unusual. After updating my profile, I used the stock prism cooler. Initially, I had to disable Auto OC features like PBO and Core Performance Boost for stable temps. Once I switched to the pre-applied paste (not my first cooler install), there were no issues. When I first put it in, I checked the paste spread after removal; it worked perfectly. After switching to MX2 paste, the performance remained consistent. When I replaced the entire cooler, the paste spread evenly again. Now I'm using the new MX4 with the upgraded cooler, achieving a 10°C drop and significantly quieter operation (temperature stays at 55°C during games).
85C to be exact But yes, there is "plenty" of headroom in terms of CPU Temp now. About the VRMs... I was thinking the same thing (CPU is consuming (with PBO and CPB around 135Watts(125W with my settings)) which is 95%+ of the "rated" 141W in Ryzen Master (Maybe that is the Max my motherboard can handle or ?). So, is there any solution for this and how can i check their temperature? (in AIDA64 there is no info about VRMs on the board - only for my GPU). For now, changing the motherboard is not a option
You might want to use HWInfo64 for all temperature readings. I've reviewed the white papers... The CPU throttle temperature reaches 90°C. A high CPU temperature alert is set at 70°C (with the stock fan running at full speed). The motherboard could be configured to throttle at 85°C, depending on the BIOS settings and installed parameters. Consider using a spot fan to cool the VRM area on the left of the CPU—it may provide some relief.
This definitely fixed the issue. I used a fan from an old Intel cooler and it stopped throttling now. EDIT: @ShrimpBrime So...I ran it a few times and restarted... The extra fan is spinning at full RPM, but it's still throttling... EDIT 2: After I built my own radiator from an old heatsink and added a 4-pin fan, all the problems disappeared. Thanks to everyone for your help.
