    Properly connect CPU fan

    Hello,

    I need to replace CPU fan and the replacement part has one free wire that is not connected to the connector. At first I thought that it has broken from the connector, but this is not the case, since it can be found on the pictures of brand new fan on ebay.

    Is this normal wire or it has some special purpose in terms of sensing the temperature or something?
    It seems that this wire is just soldered on the metal of the heatsink.

      Re: Properly connect CPU fan

      Update:
      It appears to be a sensor wire. So the question is how to properly connect it to the frame without destroying it? I guess using solder iron would destroy it.
      I have found an explanation of this additional wire here on this yt video.

          SAMSUNG UE65HU8500 ONE CONNECT pinout connector request
          by AlexVG
          Hi,
          I came across with
          SAMSUNG UE65HU8500
          ONE CONNECT BN41-02135
          Chassis GOLF_UHD_1MP_JACK

          TV can not recognise ONE CONNECT box, so I need to know the pinout of the CN 3301 connector.
          Moreover, on the main is written A5V. However, cable connected this pin to the GND.






          Maybe somebody have an experience with the same issues?
          I need your help.
          Thank you....

          Thinkpad T490 doesn't detect NVME
          by pandrew
          I have a Thinkpad T490 (NM-B901 Rev 1.0) that cannot detect an NVME M.2 SSD,
          but it works fine with a SATA M.2 SSD.

          When connecting an NVME M.2 SSD I get while booting:
          "2101: Detection error on HDD0 (Main HDD)"

          I can continue and boot a live linux distro from a USB stick, but it doesn't show up in lspci,
          and I don't notice any relevant error messages in dmesg.

          I have tried two different M.2 NVME SSDs (both working fine on a different machine),
          and the behavior is the same.

          I am pretty sure that all the important...

          Kenwood Chef KVC50 / KVL60 / KVC5000 / KVL6000 / KVL6030 / KVL6050 kitchen machine repair
          by RolandVossen
          Hello,

          I am attempting to repair a KVC50 kitchen machine. Problem is that speeds 1..5 on the speed dial do not work at all (motor is not engaged). The 'reverse' and 'slow' settings on the same dial however work properly. I removed the dial, its PCB components seems to be basic: a potentiometer, a microswitch, a couple of LEDs and a couple of SMD diodes or transistors. The dial has three cables with three connectors that hook up to the motor controller PCB. One connector (3 pins) for speed, one connector (5 pins) for the LEDs, and one connector (2 pins) for a safety switch that is...

          Meaco Arete One / Deye Dehumidifier not working
          by CG2
          I've got a dehumidifier that has stopped working. Plug it in, press the power switch, and it beeps 5 times. Nothing showing in the display (which is just two 7 segment displays) apart from the two decimal points flashing. The model is a MeacoDry Arete One 18L, which seems to be a rebadged Deye (all the boards are marked Deye). Here's what I've got so far (details in case anyone else in future should need them).

          Starting with the power board. Mains power comes in at the red connector top left. The compressor is powered by the orange connector to the right of that and is switched by...

          Toshiba Satellite M50-A keyboard connector on LA-A481P motherboard
          by michhak
          Hi guys,
          i have a damaged keyboard connector on my older Toshiba Satellite M50-A laptop. I know there is LA-A481P motherboard. In attachment pictures there is a real looking connector and i also found a schematic to the connector. But i need help with finding a real electronic part to replace the damaged connector. e.g. on aliexpress (or different page).
          It is 34pin connector and the length from pin n.1 to pin n.34 is 26mm. So it means a pitch length is 0.764 mm. I have seen connectors with 0.5mm , 0.7mm , 0.8mm and 1mm pitch length. But not with 0.75. Is it some special custom connector...
