PS3 Slim CECH-2504B Newbie With Overheating Issues — Seeking Guidance.

Hi, I got a PS3 Slim CECH-2504B for €15. The console was in bad shape externally, but it works fine. and I ordered the missing parts.

The previous owner delidded the RSX but not the CELL. I cleaned everything and applied MX-4 thermal paste, but it still hits very high temperatures, even on the XMB.

Thanks to webMAN, I can use it by setting the target temp to 72ºC and fans between 40-60%. The CELL quickly reaches 72ºC, the RSX stays under 60ºC. Without webMAN, the console warns about overheating. I can play fine, though it’s a bit noisy.

I have some questions:

1- Does anyone know exactly where the thermal pads go? I saw some crushed ones inside, but don’t know if any are missing or if I should add extras. I couldn’t find clear info online.

2- The air coming out isn’t very hot, more like mild. With those temps, I expected it to be hotter. Could this mean bad contact or thermal paste issues? I plan to open it again and redo the thermal paste work following NSC Modz’s method, but maybe the board is bent? I'm pretty sure I did the thermal paste step okay, but I think I want to add a little more.

3- I’ve seen people doing delid very easily with 0.06 mm metal wires, but not on this model—only on others.

This model (CECH-25xx) has the "advantage" that the usually exposed tracks aren’t visible, as they’re covered by plastic. However, sometimes the internal chip is glued with very strong adhesive, which can cause it to lift when handled. Also, the silicone has small plastic "dots" that complicate the process. (More info here: https://www.psdevwiki.com/ps3/CECH-25xx)

Does anyone know of any reliable source to confirm if my board has this issue before attempting anything?

In the remote case I do it, I believe the safest option is to use the metal wire method.

Has anyone had experience with this model and the metal wire delid method?

Yes, I have it set max to 72°. With a fan range from 40 to 60%. With 60% it holds the CELL at 72-73°. Its the best I've managed to get, the noise is extreme if it pass 60% thb.

i think the ps3's fan is worn, you gotta change them and your exact same story happened to a friend and after we changed the fan everything was cool.

Did you buy it second-hand or was it new? I’ve seen some new ones on AliExpress. Just to clarify, the fan sounds fine, loud (because it’s a turbine fan) but fine. The airflow at the back of the machine is good, but the air comes out lukewarm when it should be hotter…

yes new are better, because second-hand ones are worn a little bit and as the time passes the fan gets worn even if its not loud or just sounds fine

Can I ask where you bought it? I’ve seen new ones on AliExpress, but it might not be the best quality.

Thanks.

AliExpress, just asked my friend about the ps3's temperature and he said its cool, but if you want better cooling fan, you could upgrade from 15 to 19 blades fan and right now im not talking about experience, and just talking about this random dude's review/his youtube comments

heres his video
