I highly suggest using HWiNFO and HWMonitor—they’ve had the fewest problems. HWiNFO offers detailed system insights when needed. CoreTemp works poorly on AMD systems, while RealTemp isn’t always accurate. Speedfan is decent but may cause Windows crashes on some motherboards. @ LoGiCalDrm covered all of them well.
I check the system info viewer for at least 8 hours without any voltage spikes at 2 volts and without temperatures dropping to -88 degrees. Then I run hwinfo64 for 6 to 8 hours, and every half hour it shows a voltage spike of 2.3 volts. I won’t use that program again ever. Many others on overclock forums with Skylake builds face the same issue—this software doesn’t help much on a Gigabyte motherboard.
From that screenshot it’s clear the -88C reading is likely a sensor glitch. These are typically issues with the motherboard sensors, which are known to be unreliable. CPU temperatures look normal and SIV doesn’t flag this particular bad sensor either. This pattern shows up in other tools like HWmonitor and Speedfan, indicating it’s not just a software problem. The voltage readings you mentioned point to a software fault as well. Since Skylake is still relatively new, it probably just means a bug. If SIV gives better results, go for it—it’s best to choose what fits your setup. I’m currently using Speedfan and OpenHardwareMonitor because configuring HWiNFO has been too time-consuming after the motherboard change. The version with Z87 boards is problematic; it’s confusing, loses saved settings, and often crashes. It seems Skylake chipsets work better for me.
