i7-10700K Overclock temperature question

[rileyresetgg]

I recently build a new PC using the i7-10700K and MSI MPG Z490 Gaming Edge WiFi motherboard. I am playing around with the overclock setting and was able to a get a stable 4900Mhz on all 8 cores. However, I got a question on the CPU temperature -- when on idle or low load, there is always one or two cores that are on higher load (around 50%) thus having a temperature around 50°C, other cores stays around 35°C. The core that hits above 50°C will fluctuate pretty quickly -- usually by the seconds. Open Hardware Monitor and Hardware Info actually show different cores hitting above 50°C.

 

This irks me a lot becuase I want the fans stay silent in normal usage. The single core temperature makes the fans run faster and louder as a result. I am just wondering if this is normal for this CPU or I missed some overclock settings. If this is normal, I probably just need to adjust the fan to run lower speed under 55°C (which sounds odd)? Here are the PC build details:

 

CPU: i7-10700K (OC to 4900MHz)

RAM: CORSAIR - VENGEANCE RGB PRO 32GB (2x16GB) DDR4 3200

Motherboard: MSI MPG Z490 Gaming Edge WiFi (latest bios)

GPU:  NVIDIA GeForce RTX 2080 Super

Storage: Samsung SSD 980 (1TB)

Cooling: LIAN LI GALAHAD AIO240 RGB and 5 fans with Lian Li Lancool 215 case (see pic)

PSU: CORSAIR RM850x

 

Thanks for the help!

It's actually pretty rare to have full multicore utilization. In most situations just a couple of cores will be utilized more than others. This is fairly normal. 50C is nothing, though. Intel can safely go to 105C before throttling. So, if the fan noise is bothering you, you can easily dial the curve down.

Thanks Chris, if that's the case, I probably adjust the fan curve!
