Raging fuming. PS3 Failed. PC FAN EXPERTS!

[Bludge]

This is what is happening:

The graphics and cpu chips are covered with a silver metal square. the metal square is a heat spreader, which sits on top of the actual chip. there is thermal paste between the chip and the heat spreader, and then thermal paste on the heat spreader which makes contact with the heatsink.

The heat spreader isnt ment to come off, and it is siliconed to the actual board. the problem is in some cases the thermal past under the heatspreader gets into a bad state and no longer transfers the heat from the chip to the heat spreader.

if the fan problems get really bad, it will only take a few minutes for the machine to shut down even just displaying the os.

So, you need to remove the heat spreaders to clean and renew the thermal paste on the actual chip. to do this you need to get a knife or idealy a sharpened spudger to wedge in under the heat spreader to cut the silicon. You also have to be very careful not to scrape the board.

Unfortunately this is very difficult (at least on the ones i have tried it on). One i just couldnt cut away, and one i put too much upward force on the heat spreader and because the thermal paste was so hard it ripped the chip right of the board as it was welded to the heat spreader.

There are some video guides on youtube i think. good luck if you give it a go!

Already did that 1st time. Mine never has Silicone on it though being the early 60gb model.
It seems to last about 2 hours before shutting down and it aleays starts back up.
The PS3 stays super cool. No hot air at all.

Hmm, in that case i have no idea. if the paste is good between heatsink and heat spreader, and good between heatspreader and chip, and provided the fans are functioning correctly i see no reason for it over heating.

Did you use good quality thermal paste? and are the fans on full blast when the machine shuts down? have you taken it all apart again to check that everything is making good contact?

Guys
I opened up the PS3 to apply some MX4 compound. ANyway to cut a story short the USBs woudnt work so i opened it up again and now my fan connector has snapped off the motherboard so it wont solder back on.

Now my idea was to rewire the fan to a USB and plug it into my PS3 so its on all the time.

My PS3 has 3 connections
Black - Ground
Brown - 5v live i assume usually red
Grey - Voltage reg

Now i have read on the internet that ground to ground, grey/brown together connected to red and it should work.

However the fan twitches but wont spin. Its trying to spin but wont.
If i spin it myself it will kick in and spin nice and fast.

This happens if i plug it into my laptop or spare PS3.

How do i make it spin without kickstarting it since it will be inside the PS3.

Any PC gurus have this issue on PC builds?

change the fan

hey what the negative rep for nellers2001?

It happens when viewing on iPhones. You are just scrolling and accidentally click on the rep points. Without even knowing.

Maybe admins and mods need to make a button that lets the users confirm they are giving rep before actually give it..?

change the fan

I dont think there is anything wrong with the fan.

Are you sure it's 5V operated? Fan might be 12V and then 5V from USB is enough much to spin it but not to start it. Other think is even if it will spin under 5V it will not perform as it should and cooled chip might get overheated.
Sometimes in PCs I was installing larger heatsink on cpu and connecting fan under 7V (between red and yellow cable) to make it quiet. But I never try it with standard size heatsink.

If I was you I would rather try to connect it as it was even if you have to spend some extra money on it. Otherwise there is a chance for new topic "help my ps3 stop working"

That could be it.
But i cant solder the old connection to the motherboard. Even my mum whos a professional solderer said that would be difficult.
I could try and find a 5v fan that will fit in internally.

Noattwr what happwns or how hard we try we ask mum for help. ...aww bless. Rep for rattys mum
