Hi guys, recently I purchase new pc and I'm trying to overclock CPU at the moment I set 4.8Ghz on 1.20V but the temps are high. Been running RealBench for around 30 min and the temp are between 83-87C. Is there any way to lower temperature. The CPU fans are working at 1513 rpm. Thanks
My pc:
CPU Intel - Core i5-8600K 3.6GHz
CPU Cooler be quiet Dark Pro 4
Memory Corsair Vengeance LPX 32GB (2x16GB) DDR4 3000MHz
