Is because that values are predefined inside syscon, and this is what i wanted to know
#Ps4 slim change fan speed ns ps3
and the fan speed used by syscon, this never varies if both PS3 are same model This first part of the curve marked with the "preheat gap" in the table is like the "warm up"Ĭlick to expand.But using a plastic bag to close all the airflow holes to overheat it, and half a smile like a psycho thinking it could be funny if someone could appear and took me a photo while doing itĪt 73✬ i stopped the experiment, it was starting to enter in "danger zone" lolīut without the bag was lower temperatures, i dont remember because the table doesnt represents that, it cant be used to compare how good a PS3 dissipate heat in comparison with other PS3, even if are the same model, what is the same exactly is the temperatures that "triggers" the next fan speed. in around 15 minutes you should be at that temperature (starting from ambient and staying inactive in XMB) Note also how i marked a vertical dark grey line at low temperatures, because is working like a "break point" of the thermal curveīefore that dark grey line the speeds are very low (on purpose), because they wants the motherboard to reach the "minimal working temperature" fast. In webman is converted to percentage (in a scale where the 100% represents 256. so this means the fan can spin in a range of 256 different speeds This is because the speed is a value stored in 1 byte (so minimal speed is 0x00 and max is 0xFF)ĠxFF converted to decimal is 255. specially because the speeds appears in hexadecinal The table could look a bit scaring to you at first sight. You are going to like this, i have that same models, and i made a table with the factory values used by syscon on my CECH25xx, you can compare with yours to see how it matches
but the motherboard doesnt matters because are pretty much the same motherboard with a different name The motherboard inside CECH25xx is hard to know, because there are 2 posibles, the only way to know it is by opening and reading it (is written in the motherboard), is either JTP-001 or JSD-001. later they changed it and started distributing CECH25xxA=160gb and CECH25xxB=320gb
#Ps4 slim change fan speed ns series
Click to expand.You are being very detallist and i like thatītw, the CECH2504A and CECH2504B it means:ĬECH25xx series, from 04 region (europe), with A (small) or B (big) hdd capacityįor CECH25xx series A=120gb and B=250gb.
