PS3 PS3 thermal paste replacement did not help, fan still speeds up

why dont u just make a custom sealed box, it wouldnt be too hard, that they fit in then measure the air coming out from an exhaust air vent in the box, run all fans with the exact same voltages and that should tell u which pushes the most air. varying the voltages at certain stages could see different results.

I think it's not necessary to go that far also I believe the temperature of CPU&RSX is the only parameter controlling the fan speed not voltages etc. actually the voltage is constantly 12 volts. It's a PWM signal corresponding to the temperatures controls the speed percentages. And temperatures vary in response of the efficiency of the cooling system. One another thing is about currents, 19 blade fans sync more current. This results more heat producing by PSU and another thing is about fluid mechanics, where each fan shows efficiency at a certain speed of running. Yes it's not that simple and when You decide to plan a test you should make it simple and eliminate other parameters. In this case, testing various shapes and numbers of blades in different types of fans. I think it's enough to have same room temperature, same game and same hours of running and resting the console.
 
ur right its not necessary, all 3 fans will do the job perfectly fine, i only mentioned this as it would put all the myths above to bed. u would only need to hook up the simple varible speed controller module like u said that alters the pwm signal. as long as these are all the same in the tests thats all u need to confirm how much air can be moved and with which blade fan. none of the rest really matters as the change would barely be noticeable.
 
Ops, i missed this thread, just a coincidence i commented something about that myth with the 19 blades fan here

In your photo can be seen very well :)

The point is... if we need to move a volume of air from point A to point B and the separation in between them is a "hole"... then the area of that hole is critical
Lets say... 100 liters of air takes X time throught a hole of area 10cm2
But if you make the hole bigger up to 20cm2 is obvious that is going to take less time

Sure... you can "push" the air stronger to achieve the same times, but this is going to cause noise, and a decrease in the power efficience
This seems to be what the NMB-MAT does... his motor is a bit more "brute" than the others and the hole is smaller
 
Btw, i never saw anyone mentioning what im going to show, but there is a way to fix that problem i mentioned
By cutting the metal all around, this way you are making the intake hole bigger in the 19 blades fan

I dont know if the improvment is going to be worthy, but i think it makes sense... bigger hole = more air
The worst thing that could happen is you are going to damage a fan... and not even because if the experiment doesnt works you can just stick a plastic sheet over the cropped area to recover the original dimmensions

Thank you bro for pointing out this reality. I don't know why some people try to share false information. Take a look at this article for an example.
https://hubpages.com/games-hobbies/...nd-greener-ps3-system-models-cecha01-cechg01-

Let's talk more about noise, with 15 blade fan under 29 percent of speed, you are not able to hear any noises but with having the fan with 19 blades inside, it also makes a sound like continuous "sish sish sish" on lowest speed.

The information has been false ever since the myth came out of nowhere, during the YLOD days, a lot of YLOD information are either misinterpreted or pulled out from the @$$ with no actual evidence, $ony isn't stupid enough to design a fan that is faulty, the 19 Bladed one is lower quality than the 15 one, and all that myth that the 15 retained air inside the console is nothing but a fuss that someone created with no actual evidence or proof, but of course society believes in whatever they throw at the table without proof, so its no surprise that this myth stood for more than 11 years before it was debunked.

As I said in my previous comment, you need a delid. Now that I know how to do it properly (^^), I can only recommend you the same. Talking about fan blades, 15 or 19 are totally irrelevant when we are talking about a BC PS3 with that old and disgusting PSU that overheat more than my oven, and without even talking about the processors that are playing beach football in some hot caribean beach.

Examples:

CECH-E, running with a mediocre thermal paste: hits 70ºC on idle and the RSX is way cooler, 65º, due the CELL being under the damn oven. I'm gonna delid it today, and use some MX-4.

CECH-G, I have a couple of pics about this:

Delidded, with a mediocre thermal paste: https://i.imgur.com/S5TWxBr.jpg
With MX-4: https://i.imgur.com/uz1siGO.jpg

At this point using a bad thermal paste is the same as using both processors with its original paste. See what's going on?

This guy is a PS3 expert, you shoud see how he works with those motherboards. Also, you can use a metal sheet like that I took from a calendar (2020 lol) to make it quick and safe, I did it and I'm standing here like a survivor hahaha.

Hi Guys

Recently I bought a "Fat babe" Ps3 60gb and I do have the same problem. So just to confirm 19 or 15 same ****t. I took it apart clean, replace old paste on top of the CPU & RSX still loud as a vaccum.

So you recomend to take the CPU out and replace the paste there?

Also the 2 large thermal pads are a bit cracked in the middle are they any problem or not big deal? Should I replace them?

Have you installed an app to monitor temperatures and percentage of fan speed?
If yes, share the results here.
If not, try install WebMan mod and run it, it will restart the console so press PS button on your controller to activate it again, then press START+SELECT together so the monitoring window pops up on the upper right side of the display.
if your console is on OFW just turn it on and stay on XMB with no games running. wait and see how many times the fan goes faster. It looks like it takes steps up.
BTW for that old girl you've bought I guess its fan goes really loud very soon. Right?

No I don't have an app like that I tried to install webman just now but I couldn't don't know how.
Yeap the fan goes loud very soon not even 5 minutes when I turn it on.

Can you let me know how to install a monitor temperature app?
I uploaded a pic of how the board looks like those large pads if you can see they're cracked does that matter?
I have few other ps3 fat consoles that work fine no 60gb can I use parts from those and add them to my "babe"?

I was having same issues with my PS3 Fat CECHL01. Had previously installed Rebug 4.84 CFW and fan would speed up loudly after a minute. WebMan & multiMan were telling me the Cell CPU was heating up quick. I removed the Cell CPU IHS used MX4 thermal paste on CPU and top of IHS for RSX & CPU. Everything good now. :encouragement:

Hello have the same model of console and have been hit with YLOD any help would be much grateful what is Cell CPU IHS and how do i remove it and will it solve problem? Thx in advance
 
hello every one
i have s3 slim
i replaced paste, but fan speed is up , Has increased after replacement!
also CPU and rsx temperature and fan speed are not coordinated
plese help

Whatever you do just don't try to delid it yourself. Many have tried and failed. Its more safer and better to just put a big heatsink on it. I added a fan and now my ps3 fat is under 50 degees on full load. Do not put any extra holes in the ps3, just cut the area for the heatsink or else the ps3 will make a louder rumble. I drilled some holes to my ps3 but that was a first test to see if my temps went down. sadly it didn't.

Btw anyone know how to tap 12volts on a fat p version motherboard? ATM im powering the external heatsink fan with a 12 volts op plug.

Do you have 2 fans for a test ?
What i would try to do (at least initially) is to connect 1 wire of the new fan to the original fan connector
I mean... in the original connector there are 3 pins
-GND
-VOLTS
-PWM

The PWM wire is what regulates the speed... if you connect it to the new fan then the new fan is going to work in "variable speed mode"... something cool because instead of running all the time at 100% speed (causing lot of noise) there are going to be many times when the noise level is smaller

The GND and VOLTS lines could be connected directly to the PSU, keep in mind the 12v rail of the PSU becomes active only when the PS3 is working (not in standby) i think is ok this way, the fan is going to start/stop together with the 12v rail of the PSU

--------------
The reason why i mentioned is good to have 2 fans for this kind of tests is because you can do this:
1) Take the PWM signal (motherboard fan speed output) out of the PS3 case and connect it to fan_1
2) Keep fan_2 in his actual position, and power it in the same way you are doing, this is the fan that is doing the real cooling work

The point is if you do the tests this way you have the speeds of fan_1 controlled by the motherboard, and is not doing any cooling work, so you have a bit of freedom to move it, disconnect it, or replace it by other fans
I mean... for every change i would turn off the PS3... and after that is very easy to connect a different fan to the PWM wire and see if his speeds adjusts well
Is mostly a setup that allows you to see how works the PWM signal sent by the motherboard to the fan and to see if you have a fan that adjusts his speeds well to it
And just incase the fan_1 you are trying doesnt works, the PS3 is not going to overheat because you have the other fan_2 doing the real work
