Hey, I managed to get 4.7 Ghz running at 1.28 volts on my Core. I want to check if it stays steady. First, I did a stress test with HeavyLoad for 12 hours. It didn't crash, but when I open the application and click on it (so you can call this focusing on the software), it sometimes stutters but never crashes. I also tried Aida 64 and it didn't crash either. My long gaming sessions are fine too. So yeah, it feels stable enough for me right now? Second, when I run Intel Burn Test or Prime95, my temps go up to around 95 degrees Celsius. This only happens with those two apps. With Aida, HeavyLoad, and the other tests mentioned earlier, I'm at about 75C. What is wrong here? I know these programs are super demanding on the CPU. Is the heat a problem? Some people say don't use these specific apps to stress test your system. But I don't know what to do. Others say they demand way too much and it's not realistic if you just want to see how good the computer is without crashing things immediately. If other tests pass, does that mean it's okay? Third, I already have a CM Seidon 240P. Do I need to buy a new one for this?
Intel's IBT and Prime95 are tools meant for something else, not your normal use. They run special instructions just to heat up the CPU as much as possible. It did exactly that. Prime is good at finding prime numbers. Your best test is actually using your computer like you normally do. Since gaming isn't a stress test, you're probably fine there. You could try a simple thing like the CPU-Z bench tab or HWmonitor. If you ever see a temperature hit 100C, the system will slow down (throttle), and that's not good. A temperature of around 85C on a normal stress test is okay and even good for gaming or running apps.
@tal_1_ It's stable enough, probably for gaming... 4 hours a day? The heat is high but okay because the temps are still within normal limits unless something crashes. We prefer lower temperatures to make integrated circuits last longer. So far if you only get 5 more years out of your 4790k instead of 10, I think that's fine. AIO liquid coolers work great until the pump breaks or a line gets blocked. I wouldn't upgrade just yet unless it stops working well or you buy a new CPU.
Yeah, I don't really care how long my life gets me out of the military. I'll be recruited for two years and five months. Then I'll upgrade to a better job. I've heard that upgrading just to keep things stable isn't enough; I need to test things properly with Prime95 and Intel's burn tests too. Once that happens, I can get around in a Seidon 240P model.
Intel's IBT and prime95 are tools meant to push your processor to its absolute limits, which they did. They aren't really for normal use. Prime just creates numbers that look random. Your best option is actually just using it normally. Since games won't work well anyway, you're fine. You could try a simple tool like CPU-Z's bench tab or HWMonitor. If the temperature gets up to 100 degrees Celsius ©, your computer will slow down automatically to stay safe. That isn't good. But if you see it hitting 85 C during a test, that is perfectly normal for gaming or running apps.
