PS3 CECHB00 Frankie + APS-231 - is it any worth?

Hi guys,

I've got PS3 20GB CECHB00 in overall very good condition and after some fine-tunings and performing preventative maintenance (delidding RSX and CPU and replacing thermal compound, replacing all thermal pads, installing CFW to increase fan speed) I am still considering a few modifications, but I am not sure if it's worth taking the risk. I am thinking about replacing my healthy 90nm RSX to, first of all, reduce obviously the heat, with that I could also decrease the fan speed and my console eventually would run as cool as it is now (34-35% fan speed, TLOU, Ratchet Clank Crack in Time 55-58 degrees max on RSX and CPU) with lower fan speed. Also, because the 40nm RSX would decrease power consumption significantly, I am also considering replacing my APS-226 PSU to the cooler one: APS-231, which I can get for low price.

Currently I am not exceeding 55-58 degrees on both processor in any case, but the thing is the 90nm RSX is not reliable unit, meaning, after decreasing temps, I still don't feel confident that my PS3 will not get an YLOD due to degraded RSX in a half year or year. Ofc nothing is immortal, but if there is a chance to extend the lifespan of my console reatly, then why not? What do guys think?
 
No need to replace BGAs that are working fine. Also no need to replace APS-226, that is already a very efficient PSU at nearly 83% efficiency vs 81 on the APS-231.
 
Yes, but due to much lower power consumption, it also produces significantly less heat and I was wondering if because of that I could reduce temps of RSX and CELL noticeably

You are talking about spending $400+ to fix a non-issue. I would wait till the RSX dies. Cell never really dies
 
In my experience the temps with the aps 231 installed in a A00 are the same as the 226. I tested two aps 231 psu and results were the same. I assume a B00 would have similar results.

As for the frankie mod you CAN do it to future proof it I suppose but at the moment seems redundant if it works currently.

I don't know where you get the lower power consumption from. The PSU will supply as much power as is requested by the inside components. i.e. it will be the same regardless of PSU used. What does change is how hard the PSU has to work to supply that power. A lower rated PSU will have to work harder to supply a requested amount of wattage, so it will actually run hotter.

The rated efficiency is what matters if you have two PSUs with the same output.
 
My assumptions come from what people use to write on the internet, that they get lower temps on the APS-231, compared to 226. I can get APS-231 for a very low price (like 6-7 bucks), so I thought it would be worth trying. But you know - people use to say various things on the internet, so that's why I created topic here to know what you think about that idea, because I also assume, that on this forum people experimented with changing the PSU :)
 
Electricly speaking it shouldn't and i also would like to know how that was measured.
It's like going with a lower wattage PC PSU because you think it actually uses less power. But the opposite is the case because PSUs often have the best efficiency at half load. That's why i would always recommend to put an APS-226 into compatibile FAT systems. It's the unit that has to do the least amount of work.

Correct. It is also the most efficient PSU for the 90NM models
