== [[CELL BE]] internal Powermanagement ==
<div style="float:right">[[File:CellBE-heatdistribution.jpg|200px|thumb|left|[[CELL BE]] heatdistribution (on die)]]</div>
=== Characteristics ===

* Dynamic Power Managment with 5 power managment states

* 1 linear sensor

* 10 digital thermal sensors (8xSPE, PPE and?)

* THERM signal(s) are sent to [[Syscon Hardware]] via SMbus

== Motherboard Thermal Management ==
[[CELL BE]]/[[RSX]] send thermal data over SMbus towards 2 bufferchips, which in turn sends it to [[Syscon_Hardware|Syscon]] which handles fanspeeds, poweroff etc.

*Notes
**The table uses an ambient temperature of 20 celsius degrees, the value doesnt matters for the purpose of the table, is just for comparison purposes of the increments (PS3 manual states: ''Ambient Operating temperature 5°C - 35°C (41°F - 95°F)'')
**In "Temp1" column the exact temperature has no importance, there is a big gap in this first step (from minimal to around 54º the fan speed is the same), but the fan speed associated in "Speed1" is needed to know because is the minimal
**Temperatures in the format XX/YY are CELL/RSX in celsius degrees (°, <nowiki>{{degree}}</nowiki>, <nowiki>{{°}}</nowiki> or &amp;deg;)
**Fan speeds are in hexadecimal
**Increments row are in decimal
**Firmware installations can change fan configuration values in syscon so the values can vary depending of firmware
**Fan has a special "test/clean" mode that sets the fan at max speed, only works in some PS3 models, to enter this mode first disconnect power cord from the wallet, then press eject button and keep it pressed, then connect power cord to the wallet
**When the temperature of the PS3 is decreasing (like when exiting a game) it takes around 2 minutes to step back to the previous speed (to dont disturb the user with too much speed changes up and down). And never returns to the initial speed of 0x33 (tested for 20 minutes)

{{Boxframe0|content='''Test conditions'''
To make this test, first install "iris manager" and configure the fan speeds to be controlled by syscon ('''sys_sm_get_fan_policy''' in '''mode 1''' allows to see the default values syscon is using in real time at the bottom of the screen)... then turn off the PS3 and let it cool for some hours to return to ambient temperature

After this preparation start the test by turning on the PS3 and enter in iris, go to fancontrol settings screen as faster as possible, then start taking notes of how the values that appears at the bottom of the screen changes over time

This test can last over 60 minutes in some PS3 models and will not reach the higher temperature values because the efficiency of the cooling system doesnt allows the PS3 to overheat for obvious reasons. The maximun temperature on the test is not important for this table, the values of the fan speeds are (and the temperature asociated with this fan speed change)

A controlled overheat can be forced by blocking the airflow grills (any of them) with a plastic bag, only use this method for small overheats around 4º or 5º that are the normal peaks that will be present in-game. When manual overheating never exceed the '''overheat shutdown temperature''' that is around 85º because this can cause a permanent damage to the motherboard

==== using TC and ccapi ====
prerequisites:
* A PS3 in CFW and connected to the LAN.
* A PC connected to the local network.
* The PKG and the following plugin : http://www.mediafire.com/download/lec46ljzazooaqr/CcApi_2.00_package.rar
* The PC tool Temp Control 1.0 that you can find by following this link : http://www.mediafire.com/download/8hypjcxsj8lpq3j/TC101.zip
* NET Framework 4.5 installed on your PC (you can get it in the following link) : http://www.microsoft.com/en-us/download/details.aspx?id=30653

Step by step:
# Unzip the package 'CcApi_2.00_package.rar' on your pc and copy the folder 'plugins' to the root of your external hard drive or USB flash drive.
# Copy 'XX0001-ENSTONEXX_00-00000000000CCAPIv2.00.pkg' also to the root of your external hard drive or USB
# Now go to the ps3, and install the pkg 'XX0001-ENSTONEXX_00-00000000000CCAPIv2.00.pkg', then reboot when it is demanded.
# When your PS3 restarts, a popup will appear at the launch of the xmb telling you that the plugin has successfully been loaded.
# Now go to the PC, unzip the package 'TC101.zip' and run 'Temp Control.exe'.
# Enter the IP address of the PS3 in the red zone.
# Then click 'connect' in Blue.
# The temperatures will be displayed in green.
# Check the box PS3 notifications and temperatures will consistently be displayed on the TV screen.
Using this will allow you to see the actual temperature of the ps3 and to be aware when the temperature goes very high so you turn it off and avoid a problem of your ps3 system.

== Thermal Images ==

=== 90nm / 60GB FAT and 65nm / 40GB FAT ===
''These tests aren't by any means scientific, as we only heated the PS3's with the "Folding @ Home" application included with "Life With PlayStation" for about an hour, as the temperature had reached it's peak by then. The findings may surprise some of you, as earlier reports stated the 40GB PS3's used much less power and emitted less heat as a result of a smaller CELL processor and some other differences.''

<table width="100%" align="left"><tr><td align="left">''With the ambient temperature at about 22 Celcius, we started taking pictures. As you can see in the first image below, the upper-right part of the PS3 heats up the fastest, because this is where the ventilation system outputs most of the hot air building up inside of the console. Already in this image, you can see the power supply in the lower right corner heating up.''</td><td>[[File:IR 0020.jpg|200px|thumb|PS3 Thermal Imaging - IR_0020]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''The front of the PS3 didn't heat up as quickly, as we can see in the next picture. The only slightly warm part is the PS3's power supply in the lower left corner of the console as seen:''</td><td>[[File:IR 0021.jpg|200px|thumb|PS3 Thermal Imaging - IR_0021]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''The next image also shows the front of the PS3, but from a slightly elevated angle to show the top/side vents in comparison to the PSU.''</td><td>[[File:IR 0022.jpg|200px|thumb|PS3 Thermal Imaging - IR_0022]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''Now after waiting some time (7 minutes into testing), we can already see the back and side vents getting quite hot, going as high as 49 C. This is where the heatsink is sitting mostly.''</td><td>[[File:IR 0024.jpg|200px|thumb|PS3 Thermal Imaging - IR_0024]]</td></tr></table>

''Now we waited for the PS3 to REALLY heat up. Using Folding@Home, the PS3 is put under a lot of stress, although different to gaming, because the RSX is supposedly not put under as much stress. This was done because it was easier to get a uniform heat output from the system, as various games tax the system's components in different ways and at different times, being that they are not linear.''

<table width="100%" align="left"><tr><td align="left">''Sadly, in this pic, the FLIR camera was not calibrated correctly (you have to calibrate it before every pic), so it seems that the PS3 is much hotter than it really is. The heat gauge on the side tells us the actual max temp on this pic is only 29 C. Still, we can gather from this pic that only the PSU is getting hot, and the rest of the console is uniformly orange.''</td><td>[[File:IR 0026.jpg|200px|thumb|PS3 Thermal Imaging - IR_0026]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''The backside shows a different picture. The rear vents are now very warm at 45 C, compared to the rest at about 23 C, which is slightly above room temperature.''</td><td>[[File:IR 0027.jpg|200px|thumb|PS3 Thermal Imaging - IR_0027]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''Here is the backside of the PS3 after heating up. The complete bottom is getting pretty hot, but the most heat output can still be seen at the side vent, which is at 42 C.''</td><td>[[File:IR 0028.jpg|200px|thumb|PS3 Thermal Imaging - IR_0028]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''Now that we know the temperature of the 60GB after being given time to warm up under load, we connected the 40GB unit to the TV. Starting again at about 22 C, we can again see the PSU heating up from the front.''</td><td>[[File:IR 0030.jpg|200px|thumb|PS3 Thermal Imaging - IR_0030]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''After only several minutes under load, we get this picture, showing us the heat production compared to the 60GB is nearly the same at the rear vents at 47 C.''</td><td>[[File:IR 0031.jpg|200px|thumb|PS3 Thermal Imaging - IR_0031]]</td></tr></table>

<table width="100%" align="left"><tr><td align="left">''Now we looked at the bottom, and it looked quite different compared to the 60GB. Here we can actually see where the fan is located, and we can see that the distribution of heat is much more uniform. This tells us that the heatsink in the 40GB PS3's is much more efficient, even though the overall heat output is about the same. The 40GB is also a lot quieter. My 60GB unit's spins up to high speed mode quick and stays that way. The 40GB's fan speed nearly always stays one "notch" lower, making it nearly silent when gaming or watching a movie. The back of the unit is also a bit cooler than the 60GB, though the side is about the same. You'll notice fewer deep reds on the 40GB images in comparison to the images of the 60GB console.''</td><td>[[File:IR 0032.jpg|200px|thumb|PS3 Thermal Imaging - IR_0032]]</td></tr></table>

''The verdict is still a bit hard to deduce. After all, we know that the CELL in the 40GB is 65nm compared to the 90nm chip in the 60GB consoles, also using about 40 Watts less power overall. Yet, the heat signature is almost the same for both, being slightly more uniform in the 40GB. My guess is, the 40GB does indeed produce less heat, as can be deduced by the much lower weight and smaller heatsink. Thus, it can more effectively transport heat away than the older 60GB model.<br /><br />All in all, I say, Sony engineered quite a nice little piece of machinery here in terms of heat production and dissipation. Today's laptops have CPU's which usually produce less than 25 Watts of heat under load, normally never exceeding 35 watts. PS3 on the other hand can use up to 200 Watts in a case that is not that much bigger.''
