Chosen Solution

Hi I i have repaired sever PS3’s over the past month but i have not encountered something like this. The PS3 (fat) fan is not spinning. The result being that the PS3 boots with graphics and sound for a few seconds or 1 minute max before shutting down automatically, like its overheating. I have replaced the fan unit, replaced the PSU, re-flowed Motherboard and replaced all thermal material components. Still the problem persists. It seems like the fan is not getting power from the motherboard even though there seems to be no damage. Does anyone have a solution apart from replacing the motherboard? Background notes:

  • PS3 suffered YLOD
  • Sent in for repair elsewhere previously - probably re-flowed
  • When returned from repair fan runs at max from start up.
  • PS3 suffers second YLOD and fan stops working.

Garron, it is possible that the thermal sensor in the PS3’s got damaged during the reflow. Check the fan connector and see if you get any power to it. ==Update== Fan Connector

Fan Control Circuit

IC4002 location

Hope this helps, good luck.

Re solder the connection terminals from the fan to the mb

My ps3 keeps turning off seconds after I turn it on. Just wondering if anyone had any tips

My ps3 fan spins, but slowly and doesn’t ramp up as the ps3 gets warmer. This causes any overheat shutdown. 3 beeps red blink. Fan test mode works, and the fan spins quickly then. It must be the fan control circuit that doesn’t get the correct temp reading. Could this be a faulty thermal led? (In schematic)

My fan connector broke loose when disassembling my PS3 slim (CECH2004A). Might be my fault but I’m pretty sure Sony purposely built a fairly fragile part there, as the rest of the connectors are quite solid (and Sony aren’t renown for openness). Luckily the PS3 (this very model, at least) still accepts to boot even without a fan, so it’s an easy hack to connect an external power supply to the fan. An old 5v power supply (usb charger) did the trick. Simply conect the fan’s negative wire (black) to the charger’s negative wire and the other two to the charger’s positive wire. There’s also enough space to drill a small hole for the cable near the power plug.

The downside is the fan is on all the time so it’s a bit noisy and it might reduce your fan’s lifespan but it’s a very easy hack to keep your PS3 alive. See https://www.youtube.com/watch?v=6SXydvxn… (not my video but the exact same trick)
