4690K Heat Problems
4690K Heat Problems
Hey everyone,
I just tried overclocking my 4690K for the first time in my old system. I pushed it to 4 gHz at 1.32 V. It stayed stable for a few hours using Prime95, but it kept fluctuating between the mid-70s and low-80s, while idling in the high-40s. Even when I reduced the voltage and clock speed, the temperatures didn’t change much. Any thoughts on why it’s getting so hot?
Well, the radiator has been installed, but I'm not sure about its orientation. The fans seem to be placed in certain directions, and I'm curious about other areas with fans and their positions. The LLC setting in the bios needs clarification. Regarding memory configuration, it's unclear how many sticks are used, at what speed, voltage, or what the exact setup is. The pump connection and fan connections for the radiator are also unclear. The cooling profile assigned to the fans requires more details. There are many questions with limited information; I think 1.32v for 4Ghz might be too high. I suggest lowering it to around 1.3v and using Prime95 version 26.6 for a 15-minute test on Small FFT mode to check thermal performance. Other versions aren't recommended for this purpose.
Well, it seems we're still figuring out the radiator setup. The fan directions are unclear, and we need to know more about where fans are placed and their orientation elsewhere. The LLC setting in the bios requires clarification. We should check the memory configuration—how many sticks, speed, and voltage are used. The pump connection and the fans linked to the pump also need attention. The cooling profile assigned to the radiator fans must be identified. There are many questions with limited details; I think you probably don’t need 1.32v for 4Ghz. Instead, lowering it to around 1.3v and running Prime95 version 26.6 for 15 minutes on Small FFT mode could help verify thermal performance. Only version 26.6 should be used, not other versions which may cause issues. If successful, keeping temperatures under 80°C for the full 15 minutes is essential. Then, download and run Realbench for 8 hours to ensure stability.
It seems they didn't really care about getting answers at all.
Darkbreeze: I'm still unsure about the radiator installation. Can you tell me the direction the fans are facing? Where else are fans installed and how are they oriented? What is the setting for your LLC (Line load calibration) in the BIOS? How much memory, how many sticks, at what speed, and at what voltage is your memory setup? Which connection does your pump have? Which fans are connected to the radiator? What cooling profile is assigned to your radiator fans? You mentioned many questions with limited details. I really think you don’t need 1.32v for 4Ghz. Try lowering the voltage to around 1.3v and run Prime95 version 26.6, just version 26.6, for 15 minutes using Small FFT mode to check thermal performance. Other versions aren’t suitable for thermal testing because they use AVX instructions at impractical levels. Then, if it works, staying under 80°C for the entire 15 minutes, download and run Realbench for 8 hours to confirm stability. I finally tried your advice. I enabled LLC and adjusted the voltage, and everything is now stable. Thanks!
