Hi just wondering how fast my pc fans should be spinning. I ran sisandra and it said one of my fans was either not working or spinning too slowly. Currently, EVEREST is detecting my CPU fan at 2722 RPM and the case fan at 1592 RPM. It also has my new hard drive listed twice Hitachi/a 66 degrees Fahrenheit and Hitachi/b 104 degrees Fahrenheit. Thanks

reported differing fan behavior and odd drive-temperature readings from monitoring software. Before assuming hardware failure, confirm what the sensors are actually reading and where the fans are plugged in. Software can show misleading results; BIOS/UEFI hardware-monitor pages are the easiest baseline. If the BIOS agrees with the tool, treat it as real — if not, try another monitor to cross-check.

Basic troubleshooting steps:

  • Verify each fan is on the correct motherboard header (CPU fan on CPU_FAN, chassis fans on CHA_FAN). 3-pin and 4-pin fans are controlled differently; a PWM fan on a voltage-controlled header or vice versa can behave oddly.
  • Force fans to full (BIOS/UEFI or fan-control profile) to confirm they spin freely and move air. Listen for rubbing or bearing noise and inspect for dust build-up.
  • Check heatsink seating and thermal paste if CPU temperatures look high under load; a poorly seated cooler can cause elevated CPU temps even with a working fan.

About the duplicated hard-drive entry: monitoring tools sometimes read multiple temperature sources (SMART vs. a motherboard sensor) or report a drive twice when multiple controllers/bridges are present. Use a dedicated SMART reader to confirm the drive's reported temperature and check the drive maker's spec for safe operating range. Improving case airflow or moving the drive to a better-ventilated bay often helps.

As noted, acceptable temps depend on the CPU and cooler. As suggested, include motherboard, CPU, case, and fan types when asking for more targeted advice. Quick checklist: confirm BIOS readings, swap headers to test, clean fans, check SMART, and report exact hardware if problems persist.
