Overclocking temperatures for i5 4690k vary depending on settings and conditions.
Overclocking temperatures for i5 4690k vary depending on settings and conditions.
I've been attempting to overclock my i5 4690k all day, but stability has been an issue. Recently, it reached a stable 4.3 GHz with a voltage of 1.250V, and I ran Prime95 for around 20 minutes on blend. The CPU stayed between 75-76°C most of the time, occasionally spiking to 85-88°C for short bursts of 1-2 minutes before dropping back to the mid-70s. At one point it even reached 95°C for a while, then settled down again and never climbed into the 90s during the test. Are these temperatures typical for a 4.3 GHz and 1.250V setting? At idle, it operates at about 40°C, which seems reasonable. I was also using Prime95 version 29.1.
It's quite warm, so I'd aim to keep it below 80°C. When testing with Prime95, make sure to use version 26.6 since newer versions might change the voltage settings and raise temperatures. I'll carefully read through this guide by Computronix.
Temps in the mid 80s are typical under extreme stress tests like Prime95. Expect even higher temperatures, especially with a budget air cooling setup. As WildCard999 mentioned, newer Prime95 versions can affect voltage settings and lead to unexpected temperature spikes. If you notice temperatures above 85°C for more than a minute, halt the test and let your CPU rest—pushing over 90°C is beyond safe limits. If you're willing to risk voiding your warranty for optimal performance, consider delidding your CPU. This method can significantly lower temperatures but carries a high chance of damage if not done carefully. Most tests show temps dropping around 20°C under load after delidding, and I intend to do it soon for my 7700k processor.
I would save delid as a last option however Fusionxz is correct as there's a high chance of ruining the CPU but if you do need to delid the CPU you can send it out to pro's who know exactly what they're doing for a fee.

Are you sure that's a good idea? I've heard TERRIBLE reviews from those type of websites claiming pros to delid, or pre-delid a cpu and buying it from them.. Mainly false claim accusations, whether it not being delidded when the customer recieves it, or something taking much longer than they say.
Well if there is a issue with those sites then you could always buy the deliding kit and carefully do it yourself.

This is definitely the best option in my opinion. (I plan to use this exact tool to delid my 7700k)
