Predator Triton 300 pt315-51 continues to strike prochot despite applying throttle stop.
Hey there! I own a laptop that handles most of my games smoothly, but when I play BOTW in Cemu it gets really hot. I clean the fans with compressed air regularly (can’t open the back because it breaks the warranty) and used ThrottleStop to help. It worked for other games like Apex and Poe too. My BOTW settings are set low, but the issue still exists. I’ve adjusted ThrottleStop from various forums and mixed settings, but it’s not solving the problem. I’ve listed my specs and links to the settings and logs, including performance data from Cinebench. Any tips would be super helpful—I just want to enjoy gaming without worrying about overheating or battery issues!
Cleaning with an air duster isn’t the best option; you might also need to repaint it. The simplest solution was to move the laptop off whatever surface it was resting on.
I already got a laptop stand, but it seems it didn’t really help much. It’s usually quite warm—around 32 to 34 degrees in the Philippines.
The maker of your laptop has adjusted the thermal throttling threshold too low. Intel normally uses 100°C, yet they keep PROCHOT at a conservative 92°C. Check the ThrottleStop - Options panel on the right. Look for PROCHOT Offset; if it lacks a lock icon, you can modify it. Lowering the PROCHOT Offset raises the throttling limit. Your laptop runs at 8°C. Intel’s standard offset is 0, while most laptops use 2 or 3. Have you increased the core offset more? Some mobile CPUs maintain stability at -175 mV core and -120 mV cache. Try Cinebench R20 to test performance and temperature effects. https://www.techpowerup.com/download/maxon-cinebench/ Is the throttling affecting gameplay? The low setting prevents damage but may limit performance.
Thanks! It seems my PROCHOT offset remains fixed at -140. I've tried adjusting it to -145 and -150 for the core, but those caused frequent BSODs. -140 appears to be the safe limit at the moment. I ran Cinebench tests consistently scoring between 1700 and 1800, though it kept triggering PROCHOT errors. The TS bench on single threads showed no issues and stayed under the limit, averaging around 80 degrees with highs in the 70s. When lowering fan speeds, temperatures rise slightly but aren't a big concern since I rarely use slower fans. I also observed lower temps when the laptop isn't plugged in, though performance drops noticeably during use. I plan to tweak settings for battery operation. Performance throttling causes minor frame drops, but it doesn't bother me much. I'm currently playing BOTW and will keep it running all day to test stability, even though it still occasionally hits PROCHOT. Other forums suggested -180mV or higher for stability, but I've tried matching those settings and still got BSODs. Any tips?
Use a 9th Gen CPU with the cache voltage lowered to -100 mV. Observe if this improves stability. Near the stability limit, crashes or BSODs may occur unexpectedly. It’s often safe to allow a day or two before experiencing issues again, but crashes can happen immediately. Lowering the undervolt is usually necessary for consistent performance. The cache voltage adjustment tends to be the main cause of problems. After setting the cache to -100 mV, continue testing. You might find you can push the core voltage down further to -150 mV or -175 mV, provided the cache offset remains reasonable. Every processor behaves differently—what works for one user may not work for another. Some believe thermal throttling means the CPU will freeze at a single frequency, but Intel’s approach is more gradual. The CPU constantly checks its state thousands of times each second and only reduces speed minimally when needed.
