Overclocked i7-4770k, temperatures and voltages?
Hey, I just tried overclocking my i7-4770k for the first time. It was giving me terrible frames in PUBG, but after doing it, I noticed a big improvement—probably 20 to 30 frames more. However, my temperatures are getting a bit high, which is why I'm seeking advice on whether to adjust any settings. I'm not an expert and this was my first attempt, so all the tips would be really appreciated.
I used Prime95 and Aida64; both showed instant temperature drops to around 75-85°C, but after about 10 minutes I saw peaks reaching 88-93°C and stopped testing. After a few hours of gaming in PUBG, the highest temperature reached was about 78°C. Does this sound typical? Or should I consider changing something?
System details:
CPU: i7-4770K @4.5ghz / 1.180 volts
Motherboard: Asus Z87-A
GPU: Asus GeForce GTX 1080 rog strix
Memory: 16GB Kingston HyperX black DDR3 1600mhz
Cooling: Cooler Master Hyper 212 EVO on CPU and a large fan on the case.
Thanks in advance!
Which P95 version are you running? It might help to verify your BIOS settings and check for any upcoming updates. You also didn't include your current temperatures, the case details, or its airflow characteristics. For those voltage levels, it appears you're running at a higher setting.

Which BIOS version are you currently using? It would be useful to verify and compare with the one you have, as well as check for any pending updates. You didn’t mention your room temperature readings or the case details, including its design and airflow.
For the voltages you’re using, it seems you’re running at a higher level than usual. You’re using Prime95 v26.6 and performing small FFTs. It’s possible that an update to your BIOS could help, especially since your PC was built in 2013.
Your ambient temperature is around 22.4°C, and the case is Fractal Design Define R4 Black (one side open). Changing the thermal paste might be worth considering. Despite reading many guides, I’m confused because even when the system boots normally without BSODs or other issues, I still experience very high temperatures at lower voltages—most others seem to have around 1.200 volts at frequencies between 4.4 and 4.6 GHz.

Also, if you’re using Asus Auto OC profile or auto core voltage settings, the CPU may be overvolting to maintain stability. You could try fixed or offset mode and lower the voltage slightly. I’ve set the voltage manually at 1.200V, but a test showed BSOD after further adjustments.
I noticed my CPU fan spins around 1100 RPM constantly, which feels unusual—this is higher than expected for me, and there’s no change in speed even when testing different fan control settings in BIOS (standard, silent, turbo, manual with 100% duty cycle). My fan model is Coolermaster 412, not Hyper 212 Evo.
