I7 7700K model designed for high heat and changing conditions (Kraken X62)
Hey guys, I’m facing a bit of an issue. I previously discussed high temperatures on my I7, but things got worse... After cleaning and replacing the Kraken because the pump was too noisy and failed, I tried overclocking the i7 7700K to 4.8ghz at 1.21V. It worked well with 3200mhz RAM as well. However, my temperatures rise from 60-85°C in AIDA64 with FPU enabled, whereas they only reach up to 78°C without it. At first, I thought the cooler placement or paste application was off—trying different methods like spreading, pea-sized dots, and a line. But my temps keep hitting 85°C and fluctuating a lot. I also noticed the core 2 and core 3 are running 3-4°C higher than cores 0 and 1 before. With stock paste, I was hitting 88°C in AIDA64. The only improvement has been in idle temperatures, dropping from 38-39°C to 33°C. Also, at stock settings, my temps never exceeded 74°C in AIDA64 with FPU on. What’s going on? Should I try a delid or is there something else I’m doing wrong?
Air bubbles definitely aren't a positive indication, yet operating the pump at full capacity isn't ideal either. The bubbles won't reach the top and be removed from the loop; they'll simply continue being drawn down. You could attempt running it at a reduced speed for some time and adjusting its position to check if an air bubble is lodged near the CPU. I've assisted several individuals with similar issues, mainly dealing with a trapped air bubble that required loosening.
I wouldn't be concerned about short-term temperature increases, which are normal. The CPU can warm up rapidly. Air coolers offer some advantage in maintaining more stable temperatures around mid-range levels. Water coolers, on the other hand, tend to show better performance in such scenarios.
It seems accurate. Even with two 280mm radiators and a new thermal compound, my 7700k still hits 81°C. The average is near the mid-70s. I'm applying 1.4 volts to push it up to 5.0. Don't stress too much about the stress test temps. Keep your monitoring tool active and check the peak CPU temperature during regular use. I find Cinebench a good estimate for intense gaming tasks, and it helps me avoid crashes even in stability tests. AIDA 64 was my usual choice with my i7-4770k, which made me more cautious. I'd only rely on it if I needed a demanding, continuous CPU workload. The fluctuations are normal—silicon always needs time to warm up before heat can escape.
I've been monitoring my temperatures and sometimes they spike to 67C under 30% load at 4.8ghz OC (1.21V)... not sure if that's acceptable, too. I also set the pump to full power and it's producing some air bubbles or rattling sounds beyond 90% speed, something I hadn't noticed before since I never exceeded 80% speed. I've owned a Kraken X62 for 7 months now.
Air bubbles definitely aren't a positive indication, yet operating the pump at full capacity isn't ideal either. The bubbles won't have a chance to rise to the top and exit the loop, they'll just continue being drawn down. You could attempt running it at a reduced speed for a short period and adjusting its position to check if an air bubble is lodged near the CPU. I've assisted several individuals with similar issues—just a trapped air bubble that required removal.
I wouldn't be concerned about occasional temperature increases, which are normal. The CPU can warm up rapidly. Air coolers offer some advantage by maintaining more stable temperatures in the mid-range. Water coolers, on the other hand, tend to show you can continue pumping heat and it will drop to a significantly lower maximum compared to air.
I have been running my pump at 70-80% speed right after installation, even with my PC elevated. The sound disappeared at those speeds but came back when I increased it to 90-100%. I also moved the aio to the front of the case, but the screw holes are off by about 2mm or more, so I can only fit two screws and one at the bottom. I’ve also been using my cheap aircooler (about 400 grams with three heat pipes and a poor fan) for the past two days, and temperatures during gaming stayed the same or only increased by up to 2°C. I contacted the RMA and received an email saying it seems defective. Just a coincidence.
