Re: PS3 Fat RLOD reflow and now overheating message

Glad to help, dont forget to put the ac socket first before assembling.

Good job, I learned some things too

Re: PS3 Fat RLOD reflow and now overheating message

Well, applied new Thermal Paste, assembled it just for testing, and
it turned without problems for about half an hour!

Now I see the way to close this console!
Gonna assemble it completly tomorrow and fire it up for a couple of hours and confirm that the repair is good.

Thanks to all who gave the precious inputs!

Re: PS3 Fat RLOD reflow and now overheating message

cool! i will adopt your method for my next ones. the chip looks really intact, with a modified blade there always were scuffs and cuts.

Re: PS3 Fat RLOD reflow and now overheating message

I'm back!

Well, started to figure how to get that CPU IHS out of there without damaging anything...
And after searching what I had at home, decided to go with ... a fishing line !
A good quality one, and ... it worked !
Just placed it on the corners and started working it arround like a chainsaw.
It starts slowly cutting the edges ... and even slower on the middle ...but it's safe and some minutes will do it!
Some pics are attached ... on the first one, we cant see it well, but its just two tools with the fishing line attached to permit to work it arround the IHS without hurting our hands

Now some cleaning, some good paste ... and ready to test!

I'll post back results!
Hope these results can help anyone with this problem!

Cheers

Looks like Phenom II CPUs are soldered as well (http://forums.guru3d.com/showthread.php?t=294013)

That makes me happy, since that's what I run. So there should be no TIM to degrade\dry out.

Re: PS3 Fat RLOD reflow and now overheating message

I've not dabbled in desktops for a good few years, but IME, most of the high-end C2D chips had the die soldered to the IHS. On the smaller, lower-performing ones however (particularly E2xxx series), there was thermal paste between IHS and die, and the IHS could be removed by using a sharp blade. I removed the IHS from an E2180 back in the day. Rumor has it it's the same with Ivy Bridge and Haswell too.

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?

Been getting word from the internetz that Intel was using solder for the Sandy Bridge processors and that Intel decided to go a more lax route with the Ivy Bridge processors.
Possibly the same with Haswell.

Re: PS3 Fat RLOD reflow and now overheating message

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.

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.

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.

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.

[senndogg]

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.

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

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

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 !

Re: PS3 Fat RLOD reflow and now overheating message

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)
