PS3 Fat RLOD reflow and now overheating message

[magneh]

Hello!

Got a PS3 with RLOD.
Reflowed the gpu on my hot air station, and when I tested it it turned on.
Conected it to my LCD and left it here for maybe ten minutes.
As I dont have the controller, it sat there on the start screen.
I noticed that the fan started jumping from different stages to full load, and then I got a overheating message and asking to turn off the PS.

Whats the right approach here? Reballing the GPU?
Or buying a new BGA ?

Thanks for your thoughts!

Did you replace the thermal paste?

Hello!

Thanks for the reply!

Sure, cleaned all perfectly and replaced by new one.

No one with this issue on PS3 repair?

Thanks in advance

Do you have Nec/Tokin Proadlizer capacitors on your PS3 motherboard? These need to be replaced with surface mount tantalum capacitors.

Hello!

Gonna check that when I'm at the office.

Could those capacitors be the responsible for the overheating message?

Thanks in advance!

Yes.

Hello!

Just opened back the PS3 and looked for the "badcaps" NecTokin

Found 8 of them (!) , 4 on each side of the board.

Some pics are following.

Should I change'm all?
If I must do so , I need 32 (!) 330 uF 2.5V ??

Or should I start by the 4 that feed the GPU and test?

Thanks for any inputs to know the best approach to this issue!

It may be a shorted thermal probe, if it's the same type that many thermometers use. (open would cause a false 0 C reading)

Start at the GPU and then CPU with the NEC/TOKIN caps. I kinda doubt it is a bad thermal probe - otherwise it would display the overheating message from the start.

So I should change the 2 of the top of the board near the GPU?
Or should I change 4 of them, 2 on top and 2 on bottom?
And then test it?

Gonna spend all tantalum caps in tha house !

Please dont touch components after trying this!
the PS3 rsx (gpu) and cell be (processor) uses these ugly ihs to dissepate. the problem of overheating lays under the ihs which is a pita to remove. i see you have managed somehow removing the gpu ihs. now, you need thermal paste, preferably as5 for the gpu chip and THERMAL GLUE for the ram chips.
If you jailbreaked your ps3, thats another story, you can show the temperatures using multiman and several othe homebrew softwares. In most cases you will notice that in fact its the CELL BE which overheats. removing the cell ihs requires maximum efforts http://bgamods.com/forum/viewtopic.p...it=ihs+removal

Thanks for yur inputs Senndogg!
But now I'm in a dilemma.

First of all, the gpu ihs came allready like this when it came to me.
The PS didnt turn on, just blinked the red light.
I've reflowed GPU and now it turns on, but when on main screen to choose HDMI and video source, if I let it 2 mins without pressing any button, the fan starts to increase speed step by step, until overheating message.

Now that I've recieved some opinions regarding changing the NecTokin caps, I was going to do so.
Now that I've read your post, I'm kinda lost.
The PS isnt jailbreaked so I cant see which chip is getting overheating problems!

How can I proceed correctly from this point on?

Thanks for all your help!

Re: PS3 Fat RLOD reflow and now overheating message

If you applied thermal paste enough and the fan is still kicking in loud then the issue is probably the thermal paste under processor CELL BE IHS.
Dont get me wrong The unique but this is typical if Fat Nand consoles. (In this case CECHC 4 usb and mem cards)

The fan starts normally...and about 1 min after turning it on I can hear it going to stage 2-3 and finally maximum fan speed in about 2-3 minutes.
It doesnt start at full load.

So you recommend removing the other IHS and apply new paste right?
Gonna see that post and try to do it ... do you recommend applying heat during process?

Cheers

Re: PS3 Fat RLOD reflow and now overheating message

Nope, no heat for the cell be. just follow the tutorial like the one at bgamods, the one i linked you. NEVER use a razor or edge like knife. In contrary to the rsx, the cell be ihs is glued with soft silicon, you need to cut it in less than 1mm space without touching the chip, crazy thing. whatever you do, dont rush, even you havent cut 10% in 30minutes.
than apply quality thermal paste to the sole chip and try to fix it just for a try. dont worry, the 2 big screws will tight that securely.

Re: PS3 Fat RLOD reflow and now overheating message

No offense taken senndogg, i don't do consoles and your theory makes sense. I'll let you handle this one.

Re: PS3 Fat RLOD reflow and now overheating message

Its never too late The unique, I think you have all capabilities to do the nand/nor downgrade service. Start with the Teensy++ 2.0, which is a superb piece of hardware, costs just 24$ (half as a downgrade service) and if you are good enough with arduino programming you can make a decent programmer out of it.

Sounds like the issue Intel's Ivy Bridge processors have. If hot at stock or a little OC, then take the IHS off and replace the TIM under the IHS.

Re: PS3 Fat RLOD reflow and now overheating message

A bit OT, but you know, I've never even thought about there being TIM between IHS and the die... is that true on all CPUs? I guess it must be... and how long before it degrades and needs replacing?
