Hacking Default Fan Threshold payload

[arfgh]

Default Fan Threshold payload


This is a payload for FW 5.05 6.72 7.02 7.55 and 9.00 that will reveal default fan threshold in your ps4 model.
Despite was always said that default threshold is 79º in all consoles, that's false! So, discover with this payload your model value.

This is funny because before to get involved in the payloads programming i wanted a host that allow me to rise the ps4 pro first model threshold some degrees up to decrease noise. And just because all this, i have discovered a very very interesting fact about the PlayStation 4 Pros, that we all goes to discover in this thread

Of course, it is important to run this payload with a fresh console started up, and not with the threshold modificed by other payloads. We are looking for the original default values !
And most important, share here your result, because we are missing the values for several ps4 models.

Important: if you have altered fan threshold with other payloads, you have to shut down the console, and remove power, before to proceed with this testing. Also, the payload wont work if get loaded via goldhen bin-loader. Use the regular way, that is netcat in the ps4 side.

Let's see those models and their values...

Just tried it on 9.00 and it does not show a popup notification.
NetcatGUI said "Done" it didn't hang or anything but nothing happened on the PS4.

Edit:
Tried it on 6.72 and it just says "unsupported Firmware".
Tried with and without running goldHEN first and it did the same .

Tried on 5.05 and "unsupported Firmware" on that too.

 

[arfgh]

My fault.
Anyways it's nice to see the security programming in action to never goes further, even on error

The payload wont work if get loaded via goldhen bin-loader. Use the regular way, that is netcat in the ps4 side, not pc side. Info added to the op.

Redownload because it is fixed.

 

[Leeful]

I dont use the goldhen binloader. I use the regular netcatGUI on PC to regular binloader port 9021 or 9021 depending on the FW.

anyway here are my results:
I unplugged the consoles before testing to make sure any previous fan threshold sesstings were removed just in case.

PS4 Phat (CUH-1116A) on 9.00 = 80 degrees C
PS4 Slim (CUH-2016B) on 5.05 = 80 degrees C
PS4 Pro (CUH-7016B) on 6.72 = 79 degrees C

I also have a phat on 7.02 if you want to add the 7.02 offsets to the payload.

BTW After the tests I used a fan threshold payload to set the threshold down to 75 degrees C and ran your payload again and it reported 75 degrees so I can confirm that your payload is working 100%.

 

[arfgh]

the problem with 7.02 is that i dont have a console with that fw, and for that reason i never programmed for it...

More info added to the op.

I can try to add the fw 7.02 offsets to obtain data on that fw, but the problem is that some reasearch it is also required for the code... I will think on it to see a possible way...

Nice thread @arfgh

My report :

PS4 Pro (CUH 7216B) on 9.00 : 83 degrees C

Note : As @Leeful , I used regular binloader from the host (listening for me on 9020) and NetCat.Gui on PC side to send the payload.

 

[arfgh]

^^ and there it go what i did discover with main question

But, let's see if we can cover all the ps4 models, it is interesting !!

 

[Maupiti]

Dunno if useful : my PS4 Pro was new on OFW 6.70

 

[arfgh]

the info is always useful, that's the question.

 

[Randqalan]

PS4 Pro (CUH 7215B) on 9.00 : 83 degrees C

for me also and OFW new 6.70 just like @Maupiti

 

[arfgh]

added to the op same payload also valid for FW 7.02, let's see.

 

[Leeful]

Thanx for adding 7.02.

My 7.02 PS4 result:
PS4 Phat (CUH-1003A) on 7.02 = 80 degrees C

 

[Randqalan]

I am starting to think they uped the threshold on pro to make it more quiet.

 

[arfgh]

^^ exactly, and by the way the first model, that is kinda noisy, should be able to work in the value of 83 with any problem, and more quiet. It is a thing to test... anyways we still need more model values...

 

[arfgh]

new value added to the op, CUH-2215B, thx to Marcus

 

[GetAn]

PS4 Pro (CUH-7016B) on 9.00 FW = 79C

Never touched any fan threshold settings on this machine before, so it should be valid I think.

 

[arfgh]

we are still missing some model values, let's see if we can collect them all..

 

[arfgh]

Thx to MGS_PS4_PS5_HB_Tester user, we have now the missing PS4 Pro 7116 default threshold.
The op was updated for that info

 

[NEILYOUNG]

thank you i needeed this temp reference

 

[arfgh]

show your console model values, important !
