Durée et durée de vie
Hello! The idea that a CPU stays durable regardless of how close it gets to its TJMax temperature seems unlikely. The difference between temperatures like 70°C and 99°C could impact longevity, even if it's just a few degrees. I’m not sure these statements make sense, but I’d love to hear your thoughts on this. Thanks!
Imagine TJMax as your top speed (10mph) and distance as your endurance. If you run at 9.8mph, you’ll tire sooner than if you ran at 8mph, even though the gap isn’t huge. The real impact is how much farther you can go before losing energy. Sorry if this isn’t clear.
Higher temperatures accelerate breakdown, but the device remains durable for years even when operating at its maximum temperature.
Usually most devices get swapped because they're too slow or outdated, not because they fail. CPUs tend to hold up well even in poorly maintained systems, so I don't need to worry about how temperature affects their life. The chips usually wear out more at higher heat, and the decline isn't straightforward—more like a general trend rather than a strict rule. In practice, it doesn't usually matter much.
I've never experienced a CPU malfunction in more than 25 years of working with computers. I've frequently pushed my CPUs to their maximum stability and heat levels, increasing voltage beyond safe thresholds and dealing with very high temperatures. However, I've never reached a point where they throttled or posed a safety risk. As mentioned by @Electronics Wizardy, you should replace your CPU when it becomes outdated and inefficient for current tasks before you start noticing any issues. We'll observe how AM5 CPUs perform over time and how they handle heat compared to AMD, which claims their TJmax of 95°C is suitable for continuous use.
For longevity, TJMax indicates the upper safe temperature for normal CPU operation. Manufacturers like Intel or AMD accept running at that level all day. With a 5-year warranty, they guarantee performance even if the CPU overheats continuously—running Prime95 for five years without interruption, and still honoring the warranty if failure occurs before then. A TJMax of 100°C means the CPU may operate continuously at that temperature, which is viewed as acceptable. TJMax isn’t a sudden threshold that instantly damages the chip; higher temperatures accelerate wear, but real-world usage rarely pushes components beyond safe limits. Most CPUs maintain functionality well beyond their expected lifespan, regardless of workload.
Tysm all!!! My CPU is already more than ten years old. I'd like it to last a few more years. I've been using it with turbo boost off mostly until this year. Considering the replies, there seems to be a good chance for it not to die all of a sudden soon, even if it runs with turbo on from now on.
