PS3 slim fan speed

Can you try to unload webMAN, then take a look to Temperature?

what? I like to have webman monitoring with select+start, it is great feature.

ik, try to unload it and launch multiman or rebug toolbox to see the temperature if still high

For me, if webMAN is loaded the fan is really quiet but the cell and rsx are high. About 70 - 72,

When i unload it the cell is about 66 even when gaming for a hour

40 minutes ? thats a lot, the only reasons i can imagine why you are having that are:
-you have not counted well the time
-you made something that created an unestable variation of temperatures and syscon entered in some "special" fan mode
-webman has a bug and is not displaying well the speeds when are stepping back

I tried again and fan doesn't decrease speed after 1 hour in XMB, stays at 28% and temps drops to 61/61. I tried also to turn off PS3 and then turn on and fan goes to 28% again, something else bumping fan speed and not only cpu/gpu temperature.

It could be!

So can someone else test this? Play some game for 20 minutes till fan goes at 28% and then wait in xmb and see if the fan decrease speed? Also does anyone knows hot to lubricate PS3 slim fan? I looked for hole to put some oil and nothing found, also remove sticker from fan but nothing :)
 
15 inch sub surround sound , fan speed maxed out(most of the time). 41c 42c. make sure if you try playing ps2 games via cobra to set your fan speed for your ps2 emu also.
 
whaaaat? :D

Now i played Uncharted 2 longer, maybe 1 hour and got situation cpu70 gpu72 fan 29%. Then I left PS3 in XMB and after 25 minutes fan speed lowered from 29% to 28% :) cpu61 gpu61

Told you, if you wait more in XMB it will continue stepping back to lower speeds :)

Yes but I waited 1 hour and didn't drop from 28%, actually never seen drop from 28% :D

This means syscon won the staring contest by technical K.O. :)
In other words... if you wait more time it will step back, not only one time, but several times

But as mentioned before, right now (after writing about it and reading myself) i think the delay times increases when stepping back to lower speeds. What im sure is the delay times changes for every step

Anyway... there is no need to meassure that delays if you dont want (if someone wants to do it, great, please post it here, but be prepared for a loooong test)
I have updated the table in wiki to add the speeds in percentages (so you can compare with the speeds shown in webman)

I would like you to do another test, starting from ambient and taking notes about the values when temperature is increasing, this is fast to do. Copypaste this list in a .txt in your PC and update it with your values:

CECH25xx, syscon fan factory settings
step 1 | 20/20 | 0x33 (19%)
step 2 | 58/54 | 0x39 (22%)
step 3 | 59/57 | 0x3B (23%)
step 4 | 60/60 | 0x3E (24%)
step 5 | 62/61 | 0x40 (25%)
step 6 | 63/62 | 0x43 (26%)
step 7 | 64/64 | 0x45 (27%)
step 8 | 65/65 | 0x48 (28%)
step 9 | 70/69 | 0x4A (29%)
step 10 | 73/73 | 0x50 (31%)

Those are the results of my PS3, and are the same posted in wiki, your PS3 is the same model so the speeds are going to be the same... but i would like to see if is CELL or RSX (or both) what "triggers" the next fan speed
In your PS3 the temperature of CELL and RSX is very close (and in mine too), so i guess we are not going to have a clear result... but anyway maybe we see something interesting, and you was asking about this before so i guess you are interested too to see how is working :)
There is no need to make the test up to "step 10" btw... if you make it up to "step 8" or "step 9" it will be good enought



And to other people interested in this... please help me fill this table with other examples from other PS3 models :'(
At some point this info could be handy (as part of the syscon research, we need to try to see if that values are stored inside syscon eeprom)
First step to be able to change them is to find where are located... but if we dont know them then is imposible to locate them... so is a road end
Also, if at some point somebody finds a way to change them... but there is no info published about your PS3 models there are chances that you will not be able to change them ! (because no info about your PS3 model)... so even in a egoistical way consider making this test for your own benefit ;)

There are 5 fans compatibles with CECH25xx model, my PS3 have this one:
http://www.psdevwiki.com/ps3/Nidec_G10C12MS2AH-56J14
Is imposible to open it to lubricate it because is like "sealed" by pressure
If you try to open it it will break

I made a hole with a drill at the back under the sticker, but it has a metal plate... so basically by makig a hole at the back you are going to find only metal
At that point i was thinking in using the hole to "push" it and take the electronics out, but i thought was a very bad idea (even worst than making a hole) so i cancelled the experiment
The fan survived btw, but the experiment to try to lubricate it was a failure

Later i "sharped" the fan blades (the "active" edges that are "cutting" the air) with a chisel and sandpaper, it was lot of work because are very delicated
This idea is something good technically... i mean... is easy to deduce... if the "attacker edge" is more sharp the air is "cutted" better
I dont think it reduced temperatures (im not sure because i was doing other small mods to improve temperatures)
And im not sure if the noise was reduced, hard to verify
In few words... sharping the edges of the fan blades is not much worthy, but i still think is a good idea, actually there are lot of PC fans with the blades sharped

I will do that test

I will do the test but already know that fan speed is changing by CPU temps and only thing that would be different will be rsx temp :) But for temperatures above 65C for cpu I have to run game and then the rsx will be hotter than yours.
 
Hmm there is a little difference, maybe there is some kind of thermal sonde between cell and rsx and both chips have impact on fan speed. :)

step 1 | when I turn on PS3 turn on webman and see temps 34/31 (20%)
step 2 | 59/54 | 0x39 (22%)
step 3 | 60/56 | 0x3B (23%)
step 4 | 60/59 | 0x3E (24%)
step 5 | 61/59 | 0x40 (25%)
step 6 | 62/61 | 0x43 (26%)
step 7 | 64/65 | 0x45 (27%)
step 8 | 65/66 | 0x48 (28%)
and didn't go further, because I have to wait long time even in game :)

What do you thing about drilling holes above fan and putting filter for dust? I tried to run uncharted 2 with opened PS3 and fan goes just up to 25% and temps were 61/61?
 
Thx, i added your test to the table for better comparison :)
Your PS3 is the CECH25xx with JSD-001 motherboard, and mine CECH25xx with JTP-001

Is hard to make any conclusion, our values are pretty similar, but is nice because now it can be seen how it matches :)

One thing i noticed is webman is making some "roundings" when converting the values in percentages because the formula to convert speed in hex to percentage creates decimals

The first rounding (that can be confusing) happens with the first speed (the one i named "warmup" speed), the exact percentage is 19.921875... and webman rounds it up to 20%
Is not a problem, but for the table it a pita, so i guess im going to change it in the table
There is another speed where webman does a rouding like this too

Making a big hole (or several small holes) on top of the PS3 well aligned with the center of the fan for sure will help cooling
I guess the results are going to be very close to running the PS3 without the top case cover (this reduces temperatures a lot)
But imo is going to look a bit ugly




---------------
Edit:
A new version of the table with some minor changes, now looks better and is more "readable", im done with it by now, it was a bit experimental but now i think it will stay with this look indefinitivelly

i agree with Ali there thoes temps are allmost good for an A and B model but for a slim its tterrible since the chipz are smaller theres also a smaller fan for the console ;) and i suggest you to get 40 or maybe 50% fanspeed goin if that isnt too loud for ya, 40% is just more chilly for it >)
