I have a i7-4790k plugged into a Z97X-SLI card. I ran some stress tests and the CPU is running at 1.24 volts with speeds up to 4.4 GHz. It's getting very hot when it works hard, but stays cool when not working. The idle temperature is around 50 C. Is this normal? Should I turn down any voltage settings or leave them alone?

Thanks again, WildCard . Ompted , what is the room temperature? Your body heat goes up and down depending on how warm it gets outside. The normal thing to do for most rooms is set it around 22 degrees C or about 72 degrees F. Which version of CineBench did you run? Did you know that CineBench R20 is harder than R15? "Stress" tests can be all kinds of things, but they usually fall into two groups: some are changing loads while others stay steady. If your program doesn't make the processor work too hard or too little, it lets us get a good reading for how hot it gets. Here is a comparison of programs grouped as thermal and...

What CPU cooler do you have? What program are you running to check things out? When you play games, your CPU should stay below 80 degrees. If you run stress tests, it needs to stay below 85 degrees.

I set the voltage down to 1.35 volts, but the heat stayed between 80 and 90 degrees Celsius. While checking the Core temperatures during testing with CINEBENCH, I noticed my H60 Liquid AIO cooler was struggling a bit more than expected.

The temperature is still too high and the voltage is too high because the limit is 1.3V for the 4th generation CPU. If you go above this, it gets even hotter and can cause electromigration, which makes the CPU last shorter. Try running at 1.3V with speeds of 4.6 or 4.7 GHz. Also, big AIO coolers are not really that good compared to air coolers of similar prices.

I tried changing it and got my stuff down to 80-85C while using 1.23V and it's still running at 4.4 GHz. I'm pretty sure this is the lowest voltage I can get without losing speed or power. I will be buying a cooler later, but for now, the h60 should do fine in terms of how fast it runs.

If you run high stress test scores, those are better. Honestly, boosting your clock speed by that much won't really give you many more frames per second, maybe only 3 or 5 extra FPS even on heavy games. The risk of breaking things isn't worth it for that small gain.

I'll bring in the Intel Temperature Guide because it has tons of info and is totally worth checking out. You can find that guide at this link: https://forums.

Thanks again, WildCard! Ompted, what is your ambient temp? Your core gets hotter and cooler depending on how warm or cool the room is. The usual normal room temp is about 22 degrees Celsius (72 degrees Fahrenheit). Which version of CineBench did you run? Oh yeah, I know that CineBench R20 uses more power than R15. "Stress" tests are all over the place and they fall into two types: some where your processor keeps working back and forth, like stability tests, and others where it just spins at a steady pace, like thermal tests. If your software doesn't make your CPU go too high or too low, that's good because then you can get an accurate picture of how well your parts work. Here is how different tools compare for heat vs. stress: while these programs use loads from 70% to 130% of your processor power (TDP), Windows Task Manager counts every single test as if it was 100% usage, which just means the CPU was busy, not necessarily working hard. Core temps go up directly when you use more Watts of power, and that power comes from how much work you do. Prime95 v29.8 with small FFTs (AVX off) gives a steady 100% load. If your cores don't hit 80 degrees Celsius, then your CPU should handle tough real-world tasks without overheating. Here is the normal range for core temps: above 85 degrees Celsius is not recommended, and below 80 degrees Celsius is perfect. CT
