21. Clean off old heat sink compound from the 2 main

processors using Isopropyl alcohol making sure all traces

of the old heat sink compound has gone.

22. Clean both touch plates on bottom of fan/heat sink

assembly with Isopropyl alcohol until all traces of the old

heat sink compound has gone.

23. Now using a vacuum cleaner or compressed air

blower get rid of all dust build up in the case and on all

component parts of the ps3 (pay special attention to the

fan assembly and heat sink fins(MUST BE CLEAR OF


24. Typical example of dust build up. See below.

Ps3 case (dusty).

25. Once cleaned you should now have a nice pile of

bits that looks something like this, see below.

Now for the tricky bit!

26. Check the top metal cover plate (underside) for

burn-in marks, as you can see below this ps3 got very

hot before it yloded!

27. Place the ps3 mother board on a flat heat resistivesurface (kitchen work top or melamine shelf will be fine).

28. Turn heat gun on and set temperature to 350 deg

and the fan speed to low (to high and it will move the

surface mount bits).

Allow gun to get up to temperature before


29. Using a circular motion hold heat gun over areas

outlined below (keep heat gun an inch above

board/components at all times).

30. CPU side first.

31. After 15 to 20 seconds move onto the next area.

32. Once all marked areas have been heated/reflowed

on the mother board LEAVE for at least 10 to 15

minutes to cool.


33. A popping noise may be heard during cooling, don’t

worry this is normal.

Congratulations!!You have just repaired you’re yloded ps3

mother board.

38. Now its time to apply new heat sink compound to

the 2 processors, when doing this its always best to

follow the manufacturers instructions but I believe the

process is the same with all types (please check

instructions that come with paste), before continuing

39. The paste I am using is called AKASA 450 it’s a

silver based compound with a thermal conductivity of

9.24w/m deg c and an operating range of 0 to 200 deg


You can buy it from most pc shops but I get mine from

my local Maplin ( I have been told that there is a better

compound on the market called arctic silver but I haven’t

tried it as yet so the choice is yours).

40. Use syringe supplied and dispense a small worm of

compound from top to bottom on the left hand side of

processor chip, now using credit card supplied spread

compound evenly and thinly over processor face (to much

is bad and not enough is also bad) the ideal amount is

when you can almost see through the paste.

41. Now repeat on the other processor.

42. See below.
