How to test: install it as a part of the YLOD fix and see if it works...and to see if it works the way we want it (faster than stock at low speed...but still not blasting, much faster at high speed, with lots of noise) There are only so many PS3 model numbers. Just makeup a spreadsheet listing each number, the locations of the plugs, the pinouts for each plug, and the particular circuit needed in each case...or at least that is what I would do. It would be great if we could put everything in a nice simple PDF, stamp the AD logo on it, and let people repost it all over the web.

Hi Killerbug, I have the same PS3 model as you, the 40GB with the black power supply. In the older fan fix you said to use the grey wire, and in this one you said that the brown one is the PWC for most systems, was that a typo?? because everyone seems to be talking about this grey wire
Hi, I have a ps3 40gb, with 3.3v / ground / 12v - using a multimeter, I was wondering, the diagram has a R3 4.7k, while your parts list does not include it, do I have to put it there also? and where do I input the 3.3v / ground / 12v from the ps3 to the fan? what is PWM? im confuse, pls help also, using a resistor, is it ok if its solder either way, or do I have to connect the resistor in exact position? Also base on your schematics, where do I put the POT wiring? it has 3 prongs
The picture at the top of the thread is someone else's design; the parts list is for my design which is slightly different and not as good I think. If you are building this better version, then use this resistor. I'll assume you are using this newer form for the rest of the questions. In the diagram, there is a circle with a + and - symbol...ground is the wire going into the - side of the circle, 3.3v is the wire going to the +. 12v is not messed with; it goes strait from mainboard to fan and does not touch our circuit. Resistors are can be mounted in either direction. So can ceramic caps...only ceramic caps are like this; most caps are directional. Where it says, "100k@25c-Thermistor" is where you connect a 100k ohm pot...where that zig-zag line is. Pinouts vary by pot, you want to connect the two pins between which resistance changes when you turn the knob. PWM is basically just like turning a switch off and on so fast that it seems to be neither on or off, but rather like a dimmer switch. If you really care to learn the details, http://en.wikipedia.org/wiki/Pulse-width_modulation
im almost finish making this diagram, well, regarding the pwm output, I will attach this to which part of the fan? 3.3 or ground or 12v? im using a 100k pot.... so I have also 3 pins on my pot, so I can check either of 3 works? im only lost at where does that line go? and how do I attach the pot? which part of the pot should i use? what else do I put in the pot as it has 3 pins where will I get the 3.3v?
i use the 3.3v input from the motherboard (fan output) to the input of the 3.3 to the (whiteboard) and check it in the multimeter, it reads 0.3 and as soon as the unit starts, the fan stops spining... pls help
As the system comes, there are 3 wires going to the fan...a 12v, a ground, and the PWM signal wire. You don't touch the 12v or ground wires (if these are not connected, the system senses a fan fail and shuts itself off). You cut the other one...the end going to the mainboard just gets taped up; it connects to nothing. The power and 3.3v going to this circuit both come from the front of the power supply; the white wires.
many thanks to the op for this... I would like to clarify where the thermistor is shown there is another 85K resistor value... are there two resistors in series?? and if replacing these with pot (linear type 100K) there is no other resistor in this path between pins 2 & 3 of the LM. also went to local electronics store..didn't have ceramic caps so i got 100nF Green polyster caps (100V breakdown) ..this should be fine??? thanks. botn3t
Hey All To Killerbug, GeToChKn and the others who have implemented this to their systems and helping those knobs (like me) out there with their ps3 fan mod, You guys are way TOO Fu$k*n Cool. And that other dick gamemods who is hell bent on selling this idea online thats already being suggested, discussed and showen by others, yeah man....youre like a mp3 player with no codec support, LAME. Anyway love what you guys are doing if only I knew how / where to start I would implement this to help prevent YLOD on my baby. Thats right, She mah Pride n Joy. Well I'll wait till you teCH fellas pdf this sucker in bimbo terms for simpiltons like me. Cheers
I've been having a terrible time getting the photos & info I need to make a PDF...I only have two PS3 systems to play with, and there are 18 different models. When I get home, I'll post the pictures and cable pinouts of the two units I have, as well as a nice hi-res image of a CECHBxx (20GB) unit I found. Maybe from there we can list what units have what connectors, and what the pinouts are for each. I know that there are at least 3 different power connectors, possibly with different pinout orders. I also know that the fan in my slimline seems to work differently than the fan in my fatline...but I have not done much research on this yet. Here is the list of 18: CECHBxx - 20GB (BC Fatline) CECHGxx - 40GB (Fatline) CECHHxx - 40GB (Fatline) CECHJxx - 40GB (Fatline) CECHAxx - 60GB (BC Fatline) CECHCxx - 60GB (BC Fatline) CECHExx - 80GB (BC Fatline) CECHKxx - 80GB (Fatline) CECHLxx - 80GB (Fatline) CECHMxx - 80GB (Fatline) CECH-20xxA - 120GB (Slim) CECH-21xxA - 120GB (Slim) CECHPxx - 160GB (Fatline) CECHQxx - 160GB (Fatline) CECH-25xxA - 160GB (Slim) CECH-20xxB - 250GB (Slim) CECH-21xxB - 250GB (Slim) CECH-25xxB - 320GB (Slim)
Here are a few pics to start the PDF with...I don't know the pinout of the CECHBXX power connector. CECHHXX - Power Connector, Labeled CECHHXX - Fan Signal Wire CECH-20XXB - Power Connector, Labeled CECH-20XXB Fan Wiring (Labeled) CECHBXX Power Connector (not yet labeled) Note: the "3.3V and "3.1V" signals are generated by the mainboard, not by the power supply. This is the signal that the board sends to the power supply to bring it out of standby mode. This signal seems to be powerful enough to run a PWM generator on the fat units, but my PWM generator did not work on the slimline. Because of this, I have designed a third version of the fan controller that only uses the 3.1v/3.3v line as a "turn on" signal. Initial testing showed that it provides a very wide range of speed control...I just need to do a little more testing to double-confirm that the fans are using capacitors on the control signal input lines...it seems that they are designed to accept PWM control, but they really just act on the average of the voltage. [edit] new design does not work; but not because of the PWM theory from the last paragraph. The design is not even worth salvaging, so I am skipping the V4 release. Back to the drawing board...version 5 will offer wider control range as well as an auto/manual selection switch (auto being thermistor controlled; not PS3 system board controlled).
done this to two of my 60Gb phats that had ylod prior. what i noticed is with the current 100K pot there is only a small portion of the pot turn at which the fan is ajustable...before it goes really slow. Installed this under the HD cage and fits perfect even though i used polyster caps(which are bigger). adjusted the fans so the pitch of it isn't too high yet still moves SHIT load more air then before and is not noticeable ingame... no need for 19 fin or talismoon here baby... them stocker fans can move some serious air when cranked. kudos to all that contributed; am very happy with this mod. heres some pics PS.. standard disclaimer...the above is for reference ONLY and i take no responsibility for your actions i.e. totally indemnified against all claims.
