Easytune adjusts my temperatures.
Easytune adjusts my temperatures.
After applying easytune on my gigabyte z97p-d3 and resetting to defaults, the temperatures remain elevated despite low CPU usage. I've noticed that easytune can trigger errors on the CPU. Is there a method to achieve lower temperatures? (Current temps are around 45-50°C, CPU under 20%, no overclocking.) Please let me know.
Ideal to adjust manually in the BIOS, as most of these autotune and auto OC functions raise voltages beyond what's necessary - leading to increased heat generation.

I found that the high temps were because easytune enabled Spectrum Spread, and for some reason that increases idle temps.
I turned mine off under the "BCLK Adaptive Voltage" setting in the UEFI, on my Z270X-Ultra Gaming. I know this is an old question, but I couldn't find the answer anywhere so now I'm posting it everywhere that lead me to eventually find it.

Kirby - can you screenshot this in BIOS and post it? I have a Gaming 3 and don't think I have this available in my BIOS.
It could be referred to differently on various gigabyte boards, and some users may not have the chance. I'm still getting familiar with these details myself, but for the Z270X Ultra Gaming Rev 1.0 with F2 BIOS, this setting leads to BCLK Adaptive Voltage. http://imgur.com/a/OmY61
On some systems it seems to be accessed by pressing Ctrl+F1 in the main BIOS menu for additional settings, though I haven't confirmed this personally.
If your CPU FSB clock stays within a few MHz around 100MHz, it's likely Spectrum Spread isn't active, which is one way to verify at least.
Hello - I was wondering if I should check whether Spread Spectrum was turned ON or OFF in my BIOS, but I couldn't locate this option in the F6 BIOS on the Gaming 3. I was hoping it might be hidden somewhere.
I don’t have much knowledge about Spread Spectrum, but here’s what I found:
"The main purpose we introduced spread-spectrum was to lower production expenses. This helped us stay more competitive and made it easier to meet the technical FCC requirements for 'home' and 'office' emission rules. The regulations might be more about the letter than the spirit. TEMPEST is quite different.
Whenever a manufacturer can save at least a few dollars per unit in BMC (Base Manufacturing Cost), it’s very appealing—especially when dealing with millions of units. Spread-spectrum could save several dollars per unit, even after considering the costs of implementing spread-spectrum control circuits and firmware.
Spread-spectrum lets makers keep relatively high RF emissions, which significantly cuts manufacturing costs (less need for physical shielding, EMI 'fingerstock' and 'braid', wear-resistant plating and conductive paints in plastic cases, case fit tolerances, vent mesh, shielding for wiring, cable RFI ferrite cores—clip-on or permanent—and more).
If you examine older PCs with plastic cases, you’ll see some used very thick copper and metal-based painted finishes on the inside to meet FCC rules... this was a costly process and required special handling and disposal during production (which also added to the expense).
By spreading out the emitted RF energy over a broader frequency range, manufacturers can more easily adhere to the specific RF band FCC regulations."

The approach matches what I found in my research. It's a workaround that tries to bypass FCC rules by distributing the interference. It seems super unnecessary and goes against a well-designed system. Also, it's surprising to learn that someone is achieving high CPU 0% idle temps without knowing it.
