PS3 Modifying SYSCON Fan settings (Better than Webman)

[vldru]

Before checking the checksum, you need to check the changes with the command (fantbl get 0 and fantbl get 1)

Hi, haven't here at PSX-Place for a while now…

I see that PS3 CFW scene got to hardcore overclocking with voltage mods, so I wonder is Syscon magic more end-user friendly already?

I have CP2102 USB converter that is a leftover from modding a router with OpenWRT software, wondering if I could use it to reprogram fan table in 2004 and 2504 Slim models I currently have.

Is there a complete how-to guide somewhere?

Thanks!

hi. is there a noobie guide for adjusting syscon fan table on sherwoods? i have done the webman-like setting by paco on my mullion console and it's working great on me (no unnecessary loud fan on ps2 mode) but i just don't understand the hexes needed to set for sherwoods. thanks.

Hi. I did manage to solder CP2102 (actually I had soldered cables to exit through the HDD bay to be able to disconnect them and hide under the flap)
For now it's only the CECH-2004 (DYN-001) done.
I'm getting communication with the Syscon, but the issue is the thermal config writing.
The original match the one at psdevwiki
Well I did figure out how they are written before I noticed that all of this is explained above

Out of the curiosity and laziness I tried to write the CELL part to match the one in the CECH-2504 instead of thinking about my own as it seem reasonable to have two systems in the room behave the same way.

But the thing is this

Did I miss something that allows more arguments?
Just to be safe I was trying less and less at a time and reverted back to default in the end.

But I see the original post applying config to VER-001 and it definitely has more than 6 arguments at a time...

EDIT:
Well, didn't know better so I just split the CELL thermal config in parts and written it in 19 commands...
So to write JTP-001/JSD-001 CELL config into DYN-001 I had use commands below

Well as for now I get two different models that finally should behave the same way in terms of the CELL BE temperature, the next part will be configuring the RSX and maybe undervolting...
It was driving me nuts that these two Slims were behaving differently haha.

Thanks for the guide!

And yeah @NextGeneration9501 I agree the hexes are a nightmare to understand...
I don't know maybe the CELL part I had written above will be useful.
Someone might want to double check it tho but it seems fine for me, at least the system booted and looks like it behaves as expected.

Update:
I'm not sure if the TemprD are fine, but I leave here my PS3 Slim DYN-001 config that aims for 28% fan speed (delided and undervolted keeps 58°C CELL 62° RSX sitting on XMB user selection screen for 3 hours @ 24°C ambient)

EDIT: Solved this, didn't realize the console power needed to be switched off before these changes I made would take effect!

I'm working with a CECHE01 that is delidded and undervolted, have been running the webman 68c for a while. System runs cool, but it'll occasionally hit 68c and the fans go nuts for 30 seconds which is kinda annoying.

Stumbled across this thread and decided to give a custom syscon fan curve a try to keep the noise down. I copied Paco's table, wrote it to syscon and verified the changes applied.

When starting up TLOU fan speed is at 20%, temps climb slowly and eventually will reach 75c, at that point the fan ramps to 28% and the temps will level off at 68-70c.

I've tried re-writing the tables and even modifying the target temperatures, but nothing seems to change. Am I missing something?

Did you change all tables? I mean all 3)
