Fiitting a PC heatsink and fan to a PS3

Looking for some advice

After repairing my ylod PS3 i found that after about 10 mins of use the ps3 fan would ramp up to the loudness of a hairdryer. the PS3 didnt actually overheat with a warning message but the loudness was annoying.

I decided I would try to mod the ps3 to fit my own heatsink and fan
I went for putting a heatsink and fan on the cpu and one on the gpu
i got the heatsinks from a compaq evo D510

the heatsinks are rivetted onto 2 copper plates i made (with a layer of thermal compound ) and the copper plate is bolted through the system board like this. THe cpu and gpu sit nice and flush with the copper plate

I then fitted a couple of PIII 12v fans on top of the heatsinks and running without the control wire plugged in so i assumed they would be running at full speed. Would this be the case?

anyway after testing I found that the PS3 would overheat after about 30s and switch off. the original ps3 fan was exhausting the hot air off the heatsink and my modification i have tried blowing cool on to the heatsink and exhausting the air from the heatsink but both methods gave me overheating issues so I need to try something else.

Would I be better to use something like a socket 775 fan like this without the copper plate? I could make up little aluminium extension brackets to extended the heatsink holes so that the heatsink could sit directly onto the cpu or gpu

the ps3 cpu is 40mm x 40mm and the gpu is 41mm x 41mm

How can i be sure the fan is running a full speed ?

  1. i would have just cleaned the dust from the original heatsink/fan and got a replacement fan. No point in modding it.
  2. it is nice to DYI mods on hardware on Toms again
