So, I was wondering if I could get an idea of what is/was going on and if I could expect further troubles. Then suddenly on the third day after a fresh start tpfancontrol detected cpu temp and started the fan profile, So I used the other software, which worked quite nicely. Meanwhile tpfancontrol was still showing all zeroes.

Then I tried Notebook fan control 1.63 -> it detected the cpu temp! I read a lot about people with similar experience, but none with exactly the same issue -> 0 readings on both cpu and fan.

switching to BIOS mode usually ment either of two things -> constant full fan speed or none. switching the fan to manual speed made it work, it can spin in all 7 speeds. The laptop went to 80C at one occasion, but the fan didn't start. However one day I noticed a reading of 0C and fan 0. I use TPFanControl and have been using it for a long time in many machines. Wonder if someone has had the same issue. The Target curve will only change the fan speed if the temperature reaches either the minimum or the maximum.Hello, I had a strange problem with my T420.

The difference between Target and Linear is what happens between the minimum and maximum temperatures.

For example, in my curves, the fans will always spin at 100% speed if the temperature is 95 C. When the minimum or maximum temperature is reached for both of these cards, their corresponding speed will trigger. Next, you need to set a minimum speed and a maximum speed. Most suitable for desktops and laptops, where fan controls are available via sysfs(5). Depending on your needs: Fancontrol (lm-sensors) Script (written in Bash) to configure fan speeds. Basically, you're telling the app, 'I want my temperature to never exceed X, but it's okay if it never goes below Y.' There are multiple working solutions for fan control for both desktops and notebooks. All complaints on that idiotic fan profile in these gaming laptop. Both cards require you to set a minimum and a maximum temperature. We highly recommend you do not go down this path without prior knowledge of fan. First, let's focus on the Target and Linear cards since they're very similar to each other. I've already configured these cards to my personal preference. For case fans, you can use the hottest motherboard, CPU, or GPU sensor as it doesn't matter too much. Before you do anything, you need to select a temperature source.įor CPU fans, use one of your CPUrelated sensors (pick the one with the highest temperature to be safe).
