PS3 PS3 temperature vs ambient temperatures

[leandronb]

The difference of temperatures is fine for a PS3 slim, the problem has been fixed
For curiosity sake... try to change the "theme settings" to disable the wave/sparks animation playing in the background in main XMB and you should have smaller RSX temperatures
And... try to repeat the test inside rebug toolbox/multiman/irisman... this apps displays the temperature too... the difference is when you are "inside" them there is a bit of workload in CELL (but not much for RSX)... so you should have CELL temperatures a bit over RSX
And when you are "ingame"... yeah... this is when RSX should be over CELL and having fast variantion of temperaturs and temperature peaks...the resulting fan speed is always calculated using the max high peaks of RSX (i mean... is not given priority by code, is just what should happen for a healthy PS3)
All that is normal

I opened multiman and kept it open for 30 minutes, the temperatures stabilized at 61c for both cpu and rsx with a 33% fan speed on AUTO mode (shown on picture). Just by pressing PS button temps increased a bit, i also disabled the sparks on xmb. Then i played GTA V and quit to xmb after one hour, the temps stabilized at 60/64 at 39% on xmb with sparks off.

The Temps are in good range. People have obsession of running PS3 at low Temps at range which is an overkill. No need to set Auto Temp at 65c. I would say that 70c or 68c is an acceptable limit. Also you should be testing your Temps on Games like GTA5 (highly recommended), Uncharted 3 & TLOU to get the real picture about performance. Also the CELL/RSX Temps are more accurate after about 1 hour of gameplay. So start from ambient temperature and take Temps after 1 hour of gameplay. PS3 takes about an hour to fully heat up.

By the way, what tools did you use to delid?

I played GTA V for an hour in single player mode and got 60c CPU and 68c RSX with 47% fan speed. Ambient temperature is around 33c, kinda hot and at 47% is audible for the fan but i think if the fan get lower the rsx will increase more the temperature so i'm not sure if is better to leave fan on AUTO or use 68c max temp. I also noticed that when a cutscene plays and end the temperature drops a bit, around 5c, and fan drops too, but when the game resumes the temperature increase really fast these 5c or more and the fan has to work harder to keep the temps at the same level it was before.

Thats perfect, just 1ºC or 2ºC of difference after 30 minutes inside an app, it means the heat is trasfered very well
If you repeat the test starting from ambient (around 30ºC) you are going to see the CELL is a bit hotter in the first lets say... 5 minutes... and after 30 minutes the temperatures are ballanced like in your results

Btw, for this test is not needed to use custom fan settings, you could disable webman (or configure to syscon to alllow it to use the factory settings), and the results will be a bit higer temperatures (maybe 4ºC or 5ºC bigger for both), but the difference in betweem them should still be very small

People have obsession of running PS3 at low Temps

Ive seen people reporting 50ºC or 45ºC and my reactions are 1) wtf, 2) or is a lie, 3) or incorect meassurement

The "wtf" is because are temperatures smaller than the 55ºC used as a "warmup" in all PS3 models... i mean... is too much different than the factory settings, and personally i dont like to differ too much from what the engineers calculated
In other words... i would like to "copy" the temperature curve used by sony enginers and "customize" it a bit (of course boosting speeds at all ranges), but preserving the curvature i painted in a graphic in my previous post of this thread
Since some months ago when some syscon models was dumped (and the fantable mapped) we can do this adjustments a lot more accuratelly because we know exactly what sony engineers did
We dont have samples of the fantable used in PS3 slim models though, and this sucks because sony made an important change in the fan control for the slims (we could say what they was doing in PS3 FAT was bad, and they fixed it for slims, so the fantable of the PS3 slims is "the good one", even for using it in FATS)

The "lie" is because some people thinks this is a competition, if they sees the RSX is moving temperatures up and down 55ºC and 60ºC they reports 54ºC because it makes them feel better

The "incorrect meassurement" is because well... you know... what we need to check is the max temperature peaks (that usually happens in RSX), and to achieve this we really need to make a good "stress test"... and we should be able to replicate it as many times we need, becaue this allows us to compare the results before/after a thermal paste replacement, or some hardware modding, and to compare with other users, etc...
Some people just reports a value that is an intermediate temperature (not the max) so is pointless

------------
There are 2 kind of tests you could do, in the test i was talking about with @leandronb the goal is to have a very stable temperature, and the better way to achieve an stable temperature is either in main XMB, or inside a homebrew app (idle and waiting as many time is needed for the temperatures to stabilize)

The other is like an stress test, and is something different, here the goal is to generate the higher temperature posible to find the max

I can get into the high fifties with ps2 games running for about half an hour, but I have my static temp at 50 percent with ps2 games. I think that's a good figure. I don't get the obsession with temps. I used to be that way with the 360 after a failed xenon, but it's not worth gaming on the system, if that's all you think about. I think with advent of temp monitors that you can see people were unaware that the system was getting as hot as it is. it's normal.

When playing a PS2 game in PS3 is a lot more tricky, to see how temperatures varies is needed to use a patched emulator (published by 3141card and released as a pkg by kozarovv as far i rememer) that displays the temperature "ingame"
This is the only way to "catch" the posible max temperature peaks, but what you need to do sucks a bit because is like fishing... you need to open the menu to look at temperature every few seconds, to try to catch a max peak... but this depends of your luck, and also if the game is demanding, and the specific points of the game where it does the max temperature peaks, etc...
So... the probability to catch a max is very low

And if you "quit" the game (to return to XMB and check temperature with webman or other app)... then is posible in that few seconds needed to return to XMB the temperature have decreases too much and what you see in XMB is not realistic
Lets say... if you see 50ºC in XMB maybe it means 5 seconds ago it was in 55ºC

 

[pinky]

that's actually what I did. I checked after each stage. the temperature increases 'til it reaches a peak at about 62.

Ahh, ok, then nice, thats a good number, and if you meassured it "ingame" trying to catch the max peaks then it should be realistic
I dont know which PS3 game could be used for this kind of stress test in PS3 btw (it needs to be one of the games reported as "playable" in the psdevwiki compatibility list), but i guess some of the god of war are good candidates, maybe the GTA's too

For the PS3 GTAV is a good guinea pig, and there is a nice way to replicate the stress test (rolling around in the sea with a jetbike, tip provided by kozarovv)... so maybe we could do the same with the GTA's for PS2

while I would agree, I think the issue is being concerned about cooling at all. how can you enjoy the system?

 

[sandungas]

Well, i had that obsession for cooling since i bought a xbox360, and later with the PS3 (the precursor horny console gen) and at some point i decided to buy a hardware mod to boost the PS3 fan speeds, and since that point (years ago) i have not used any custom fancontrol software in PS3
It was a liberation, it freed my mind

 

[pinky]

that's what worries me about the ps5. with that much power, you know where they cut corners, cooling as usual. I watched a review of the ps4 pro, and the guy said the thing got so hot that you could boil an egg on it. great job, sony!

 

[pinky]

I read recently that the wii u doesn't even have thermal sensors, because it doesn't need to. I can't confirm that. however, I play mine daily for the past four or five years, and I've never had a problem with it.

At first i thought it was going to be a low power device because AMD is in a race for low powered APU's (and i was happy to see how the horny consoles was going to dissapear), when was filtered/found some images of a PS5 debug/prototype (with a huge PSU) it shocked me a bit, later in cerny conference it was mentioned the performance and cooling, so all and all... is still a bit doutfull how much heat is going to generate the PS5

The AMD APU is going to be very efficient, thats for sure, even considering sony asked AMD to integrate some controllers and "magical stuff" to customize it a bit/lot for the PS5
But the heat maybe comes also from the SSD's, the system one is going to be in the "top tier" of this technology so most probably is going to be hot
Dunno, the PS5 is going to be a bit special

Anyway... im guessing sony is going to use the same philosophy about reducing the fan speeds (under recommended levels) to achieve that placebo effect of... low noise = low temperature
There is many people that doesnt spends a second in thinking about it, they thinks the console is working great because doesnt makes noise
Is like boiling a frog... you need to boil it slowlly because this way the frog doesnt realizes what is happening

Personally, i don't know why Sony tried to cut corners on PS3. i mean, they were selling a $599 machine which was really expensive at that time. With $20 more, they could have build a better chassis & better thermal dissipation solution (i would personally prefer a fan directly on top of CPU & RSX like PC plus a small system fan for chassis). Of course that means that Console may be a little bigger. But who cares? The build quality & long lasting of product should be the first priority specially if you are selling $599 product.

 

[pinky]

cerny lies, remember what he said about the ps vita? he said there are going to be hundreds of psp games available at launch. north america got 9, yes 9.

 

[pinky]

the high price of the ps3 was just to get cell and bluray into people's homes. you were paying them for a trojan horse. personally, I like HVD. that beats the heal out of bluray any day. a theoretical limit of 6TBs.

The console manufacturers was caring a lot about the size in that generation, in the xbox360 is very notable

The GPU heatsink is at left, that small piece of... shit

The only posible explanation for this retarded design is they was not able to exceed a specific volume (in liters) for the total case size
Sony was playing the same game, and additionally there was someone saying "we cant exceed an specific noise level"
Join that 2 design requirements together and you have the perfect recipe for the disaster

 

[pinky]

the good thing about the ps4 is that it continues cycling cool air (not sure if it's only in rest mode though, but I don't think so) by leaving the fan running 'til it hits a certain temp. I don't know about the xbone, but @habib mentioned his being very quiet. I don't know what to make of that.

 

[db260179]

Yes, and since the infomation about the syscon popped up, I couldnt wait to figure out how to set the factory fan settings to a sane set of values.

This is now my dream come true, and great to see my old PS3 run cool and quiet without software/hardware mods

[db260179]

I think sony where in a rush to get it out of the door, they where a bit late to the party and took a calculated risk.

If there engineers took a bit more time, they could of tweaked the fan settings for the old models to be just right.

But probably some marketing person said, 'No it must be quiet, customers dont wont noise!' - usual bullshit.

I think if my dad heard the computer making a loud noise, he'd think something was wrong with it. I assume sony and microsoft were under the same mindset. microsoft tried to rush their system out first, which they did, but neglected to disable the jtag points on the board, which lead to the first real 360 hack. I once read that microsoft forgot about the optical drive when designing the cooling mechanic to the system, like they forgot that it would take up space. wtf!?

Actually i know the reason for this. I saw some documentary which said that XBox Chassis concept was adopted even before Microsoft had figured out all the internal hardware. So basically 1st gen XBox was about fitting all the hardware in pre conceived Chassis design.
