For quite some time PlayStation 4 scene developers have been researching and testing code to control the PS4 fan speed in order to adjust the console's temperature, and following the PS4 Homebrew PKG Store developer @Joaquin Salih (aka toxxic407) made available a collection of payloads via Twitter used to control the PS4 fan speed on Github.

Download: PS4-fan-control-payloads-master.zip / GIT

Recently PlayStation 4 Fan Control code from ethylamine's repository based on Zer0xFF's findings was forked by kozarovv for a 4.74 port and added to JgDuff's PS4 Exploit Host v0.4.6 updates as well. (y)

Below are some additional details from the README.md: PS4 Fan Control Payloads

Collection of Payloads used to control the fan of PS4's on version 5.05. All Credit goes to ethylamine, Zer0xFF (Twitter), theorywrong (Twitter), xvortex (Twitter) and zecoxao (Twitter). The name is equal to the Temperature threshold in degrees.

:alert: Most of the Payloads are not tested! I do not take any responsibility and I am not liable for any damage done to your PS4!

@Joaquin Salih Yep tested on 2 monitors and 2 TVs results are the same. Done some further testing and got the following results:
  • PS4 Slim - CUH-20xx - Not Booting
  • PS4 Pro - CUH-70xx - Booting
  • PS4 Pro - CUH-71xx - Not Booting
  • PS4 Pro - CUH-71xx - Not Booting
  • PS4 Pro - CUH-71xx - Booting
The known booting linux PS4 + USB drive will work on any monitor\TV. The non Booting PS4 using a known working bootable USB drive and known working monitor\TV still won't boot.

As you can see even with matching models not all PS4s will boot psxitarc v2 linux. So there must still be some incompatibilities there in the paypload or Linux.

I tried the 60.bin and 65.bin 5.05 payloads on my Slim but it's way too loud. In the end i don't care too much about the noise if this can prolongs the lifespan of the console, but my concern is: isn't it dangerous for the fans spinning so fast for a long period of time? For now i reset to sony default. For example i have a RGH Xbox 360 and a CFW PS3 both set on 60° C threshold, but they are not so loud.

@AdamJensen not dangerous for the fan to run faster but doing so will decrease the lifespan of the fan, alternately running the fan faster should increase the lifespan of the console.

If your skilled enough and your PS4 is out of warranty I would recommend replacing the thermal paste between the processor and the heat sink.

Though anyone wanting to replace the thermal paste needs to be aware that there is always a risk of stressing the motherboard solder points and components resulting in a faulty PS4, especially when it comes to lifting the motherboard away from the heat sink. The old paste will not want the motherboard to separate and the board might ever so slightly bend and flex doing so.

I Recommend heating the PS4 with play beforehand or heating the heat sink with a hair drier before ever so gently lifting the motherboard while at the same time ever so slightly rock it side to side. Doing so they should come apart a lot easier.

That means the fan of PS4 V1 Fat normaly starts at 80 degrees.

Are you sure that would work? Correct me if im wrong but Settings are stored in HDD not Ram and hdd does not lose data when there is no electric current
