Is your new PC overheating during a stress test?
Is your new PC overheating during a stress test?
I just purchased a new PC and completed several stress tests on default. Using cinebench, prima 95, and intelburn test, it performed well, reaching 80°C and rising quickly to the 90s. I was puzzled, so I overclocked it to 4.6 GHz at 1.190V, and the PC handled cinebench at 50-60°C, but on the prima 95/burn test, it reached 70°C immediately and climbed within five minutes into the 80s. I’m new to this process—was my cooling system sufficient? Here are my specifications: Intel core i5-8600K CPU @ 3.60 GHz, 6-core motherboard, DDR4 G-Skill 8 GB x2 RAM, NVIDIA 1070 GPU, and a Thermaltake 3.0 liquid cooler for the CPU. Any advice would be appreciated; I’m quite confused.
Anonymouselite5 asks for clarification on the Thermaltake 3.0 model, whether it's dual rads or single. They mention normal high temperatures in Prime 95 due to increased CPU load and suggest practical stress tests like gaming, 3Dmark, Asus realbench, or rendering videos in Sony Vegas. They note that Prime95 helps with heat testing but still experiences crashes during quick games. They also reference performance at 5GHz-4.9GHz frequencies.
This is one of the dual rads or the single model?
Either way, high temperatures in Prime 95 are normal, it increases the load on the CPU more than any typical application will. So the 80's aren't too bad.
I’d prefer more practical stability tests—gaming (like BF4, GTA5), 3dmark, Asus’s realbench, or even rendering videos in Sony Vegas without a reason.
😉
Also, it appears that more practical stress tests yield better results. Prime95 is suitable for checking heat, but even after stability checks in stress tests, my PC still crashes due to instability when playing quick games.
From what I’ve read (without having a 8600k to experiment with), people who reach 5ghz-4.9ghz usually have around 1.32v+ voltage and exceed 90°C during stress tests. So it still looks like a rather hot CPU.
Short Answer: The 80's are acceptable for a test like Prime 95.
This is one of the dual rads or the single? Either way, high temperatures in Prime 95 are normal and put more strain on the CPU than any typical program will. So the 80's aren't too bad after all. I’d prefer more realistic stability tests—games like BF4 and GTA5 look decent, 3dmark, Asus’s realbench, or even rendering videos in Sony Vegas would be useful.
Also, it seems practical stress tests give better results. Prime95 is good for heat checks, but after stress testing, my PC still crashes due to instability when playing games. From what I’ve read (without a 8600k), people hitting 5ghz-4.9ghz usually have around 1.32v+ voltage and reach over 90°C in tests. So it still feels like a very hot CPU.
Short Answer: The 80’s are okay for tests like Prime 95.
Thanks for the reply. I pushed it to 4.8 but it got quite warm for me, haha. Any other suggestions on how to improve stability further? Like, should I consider using water cooling for the whole PC?
Intel is here for you. Consider reapplying the thermal paste, and if it fails, try disassembling or lowering the clock speed.
The question asks for a comparison of different Thermaltake models, focusing on performance under stress and practical usage scenarios. It mentions testing stability in games like BF4 and GTA5, using tools such as Prime95, and notes that even at high temperatures, the system remains functional. The response discusses temperature readings, cooling methods, and suggests upgrading to better thermal solutions for improved results.
