    Replace heat sink (or add fan) tips?

    I've seen several posts advising replacing the heat sink on various boards (in my case it's for the main board on a 60pv450 lg plasma (attached). Any general advice on where to get heat sinks that are improvements over the old one? Last thing I want to do is make it worse than before--is "bigger" all I'm trying to go with here? Also--is putting a fan in worth the effort--and any advice on what kind of fan and how to attach / wire it in?

    First is the heat sink really hot when the board is in use?

      it's a good looking sink.

      is it glued on, or held with tape?
      if tape then step1 is to remove it, clean it and refit with thermal glue.

      because the heatsink must take the heat from the chip.
      then it must transfer it to the air - so is there airflow?

        My advise follow what Stj said, replace the thermal pad with thermal glue. Then add a small fan over it.

          Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages

          The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

          Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
          by acedogblast
          This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

          There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

          by Jeroentje
          Hi

          I try to repair a asus Asus X571GT (DA0XKTMB8C0) no power no lights.
          I saw a burned (small hole in it) chip (JW10F) proberly a TPS22976DPUR, I removed it, now with power connected the laptop turns on and direct off again, power led and fn will light up.
          I found on a donor lenovo board a G2898KD1U (wa9y), looks the same ..
          Result is still the same, turns on and direct off again, first attempt is with backlight on all other direct attempts are only the power and fn led.

          Could it be the chip is to diffrent to make the laptop work again ?

          Dell E6540 laptop completely dead after dssasembly
          by max-power
          Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
          that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.

          After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place...

          ATX power supply keeps blowing PFC mosfets — Cooler Master RS-550-ACAA-E3
          by davidebaldini
          This is an ATX PSU rated for 550W powering 24/7 a computer load of about 200W, fed by a line-interactive 1500VA UPS. Mains is 230V.
          1. First issue: the PSU blew a mosfet on what I think is the active PFC boost converter, shorting its G D S pins together causing a short across the + and - lines produced by the rectifier on the 230V mains. The surge protector of the house tripped. When this happened I found that the UPS was unexpectedly disconnected from the wires of its battery. The UPS wasn't damaged, but I suspect this spontaneous detachment of a battery wire caused a condition that blew
