    820-3332-A Fans on Fullspeed

    Hi,

    have an Macbook Pro in front of me where a cap was shorted. It was one of these big ones where PPVIN_S5_HS goes in and I changed it.

    The board now starts again but the fans run on full-speed and a PRAM reset didn't help.


    Unfortunately I don't know the working principles of the thermal sensors. I guess there is some problem with U5550 or the circuit its connected to.

    Is there anybody who can give me a hint for what I should look for.

    Thanks in advance and have a nice day.

          RTX3090 working fine but fans not spinning
          by emil_t
          Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....

          Hot Water Rad - A Few ECU Fans and a Timer Switch
          by JayPoorJay
          Good Afternoon, Good People.

          I know this will be an elementary little project for most if not all of you, but I thought I would write a post and get put on track, rather than bumbling my way through it with all kinds of trials and errors.

          I REALLY would appreciate y'alls help.

          This is the problem - My wife and I purchased a big ol Victorian/Colonial House in NYC two years ago. The kitchen is surrounded on 3 sides by exterior walls, there is also a 1/4 of the kitchen floor (ceramic tiles) that has a crawl space underneath, and the kitchen gets FREEZING cold...

          my Xiaomi Notebook Pro X laptop fans work like crazy for no reason
          by sda sad
          Hope this is the right place, someone can help me.
          My laptop started having a really strange problem....
          When I turn it on the fans start working at a crazy rate and with random breaks...
          They can work for say 10 seconds and stop for 2 seconds and then turn on again for 5 etc...
          And it's from 0 to 100%. I tried to install AIDA and did the processor chip test and the graphics did not exceed 70 degrees and the fans were not even close to working at the power they work randomly.

          The model of the computer:
          Xiaomi Notebook Pro X 15 OLED (A30)

          Dell Precision 5530 15" died to blown chip. Replaced chip and now only get momentary fans, lights, no screen or boot
          by joesmoe91
          Hello,

          My Dell Precision 5530 turned off suddenly when I was running Matlab and wouldn't turn on, show any lights, fans, and/or any signs of activity at all. I opened the case, removed the battery and looked at the board with a thermal camera while the AC adapter was connected. I saw that PU1252 was >120C so figured the chip had died on me Got the part number off the attached schematic (see Mouser link below) and replaced the chip. After replacing the chip the board (connected to AC adapter) was able to briefly power on, spin the fans a little bit, and turn on the front led lights....

          Spectre X360 DAX38CMBAG0 - overheating fans not spinning
          by magneh
          Hello all

          Got this Spectre with an overheating problem.
          I verified that the fans start briefly during power up, but never turn on again,
          even when stress testing the machine and CPU at 100°C fans dont spin

          Ive measured and I have 5V, 3.3v and 3rd pin 0.
          When fans spin during start up, the signal at 0v is at 1.6v.

          Probably its Fan2Sig pin and 3.3V is PWM, not sure

          Question is , how to fix?
          I think these signals come from ITE controller am I right?
          Should I bother replacing it?

          Thanks...
