i5 4690k safe temperatures?
Happy 2016! I just got an i5 4690k and attempted to overclock it to 4.0 GHz with a vcore of 1.05. My Max temp under prime95 small fft's is 67 degrees Celsius. What should be the safe temperature? I'm using a Hyper 212 EVO for cooling. Thanks!
Don't worry, prime and other stress tests always run at higher temperatures than what you'll face during gaming or rendering. Even 67 under load is acceptable.

if your number is 67 in prime, you'll get about 55 to 60 in gaming which is totally okay
If you increase the frequency and voltage core, the mid to high 70s under prime95 could still be considered safe depending on the system.
It's only a modest boost since the base 4690k will reach 3.9 GHz... and remember, with stock settings and the built-in cooler, you'll hit 85°C within seconds.
Prime95 remains the benchmark for pushing overclocks, yet its value has long since passed its prime.
1. The updated Prime 95 models, which incorporate AVX and newer features, can easily damage your CPU. This happens unless you manually adjust the voltage (without adaptive or power-saving settings), causing voltage surges when AVX is active to rise by approximately 0.13.
2. Many users stick with the older P95 that lacks these enhancements. Running P95 for four hours only demonstrates stability in the absence of those instructions. What happens when they are present?
3. I still rely on Prime95 to fine-tune TIM values. I can quickly raise CPU temperatures above 85°C for a short time, then let it settle. After several cycles, most non-AS5 TIMs will reach optimal settings.
4. I also use RoG Real Bench:
a) Systems that have completed an 8-hour P95 run often crash after just 45 minutes in RB due to RB's varied instruction set handling. P95 focuses on one specific task, unlike RB.
b) This consistent stress forces the CPU to perform a single operation repeatedly, potentially pushing temperatures to 80°C—far beyond the safe limit of 65°C for regular use. This limits your maximum overclock safely.
c) When AVX and other instructions are active in RoG Real Bench, the benchmark reflects real-world programs. Voltage spikes occur during these tests. With a good monitoring tool like HWiNFO64, you'll notice noticeable jumps. However, synthetic boosts can be sustained, which isn't ideal.
A 980 Ti (TDP = 165 watts) will draw peak power more than twice its TDP (359 watts) before overclocking.
Your PSU should handle it since capacitors manage short-term spikes, and cooling systems are designed for average loads. But if two cards each draw around 359 watts continuously, either the components will fail prematurely.
With a Hyper 212, stable performance up to 4.4–4.5 GHz is achievable with 2-hour RoG Real Bench runs. Your typical core temps range from 70°C to 79°C, which is acceptable for most gaming scenarios.
