PS3 slim fan speed

Ok, today i got PS3 slim case for free :) So I can experiment with that case and not ruin my :) I thought to try 2 things, make bigger holes in lower part of spare case and put my upper part and second make holes in upper part of spare case and use lower part from my :) So I could see what is best.
My PS3 is in vertical position so don't know is that important? So in vertical position fan is on lower side of PS3 and Blu Ray drive is above. For the start I thought just to make bigger holes on the side below fan, that is left side of lower part PS3 in horizontal position, what do you think about that? Also acceptable finishing isn't important on lower side because that side is lower and hidden :)

I think is better to make holes at front, is like if the case design is "ready" to make them bigger in a easy way
At left side is hard and will look much worst, is hard to explain but lets say... for every hole you need to increase his size 2 times, because every hole has 2 "bottlenecks"
If you remove 1 of the bottleneck for every hole is like doing nothing... so is needed to remove both... or you will get nothing

I found a nice collection of photos of this parts https://www.ifixit.com/Guide/PlayStation+3+Slim+Lower+Case+Replacement/3233

Btw, one of the small mods i made... take the top case cover and flip it to see how is made under
Do you see a plastic "wall" all along from front to back ?... remove it !... this alows the fresh air to move easilly from the holes at the right border to the fan located at left
Additionally... do you see another 2 small walls from left to right ?... yeah remove them too :P
The purpose of this "walls" is to make the top case surface a bit more robust, are like "tendons" to make the structure stronger on top... but you are not going to place any weight on top of the PS3, right ?... so no needed ;)


Edit:
Also, remove the foam tape sticked on top of the bluray drive (that matches with the plastic wall i suggested to remove)
The big plastic wall (from front to back) lies on top of the foam tape... so is needed to remove both, the palstic wall and the foam tape (or none if you dont like this mod) because are intended to work together

Hmm not sure to understand you :) I thought just to make these holes bigger, lets say to make rectangles 5-8mm wide, I don't care to look nice because it is lower side in my case because PS3 is sitting on that side :)

Yes, that holes, but as i mentioned every one of them is "double"... because is not a single "plane" what you need to cut
For every hole you need to cut at 2 "planes"

In other words... are not simply "holes" but more like a "channel" (with 2 holes)

And how about to just drill extra 2-3mm holes near that holes?

Yes, this is what i was thinking right now, but dont do it yet, give me some time to make a drawing for you to see how is the best way to drill them ;)
I have the parts in front of my nose, and im meassuring them with a micrometer, if you make the holes in the angle i have in mind... there is a max available "gap" of 6mm
But is better to use a drill of 5mm... the hole will be 6mm anyway ;) (and the total area of every hole will be bigger than a circle of 6mm ) ;) ;)

I see many advantages of doing it this way:
-is easy
-if done well (no external scratches) it will not be visible externally
-the holes are big, the drill used is 5mm but the area of every hole will be even bigger than a circle of 6mm
-it solves the problem i was mentioning before of the "double holes" that are mostly like "channels", by drilling in this angle you are transpassing the whole channel entirelly side to side
-the strenght of the structure will be respected because is easy to preserve that "tendons" in between holes (dont break them btw)


You should use a thin metal sheet to protect the wall/s that could be damaged by the drill... this is a safe way to prevent the scratches caused by the drill
And imo you should not change the angle of the drill at any time... just make a perfectly vertical hole and take the drill out as soon as posible, lol
Rest of the work (for every hole) needs to be made manually, and with some care :)

Edit:
And this is like a sample of where the hole needs to be located when looking at it from outside of the case
It can be seen only if you flip the PS3

The hole doesnt touches the "walls" when looking at it from outside, is located "in between them" but not touching them
Try to be very precise with where are located... i think if you made it carefully drilling from inside, and not changing the verticallity of the drill at any time the holes will be located exactly where im painting it in this image... there is no need to make calculations... they should be there "naturally" because you are drilling aligned to the internal wall

I am not talking about drilling big hole aligned with fan, I just posted this picture where it seems like there is not enough space between fan and upper case, inside ps3!? Like it is not left enough space, so maybe it is bottleneck there? What do you think?
 
I think in that mod the fan has been "elevated" some milimeters and "rotated" a bit to make it match with the top case. Nah, after thinking in it i think the fan is in his place, is just an effect of the photo

In a normal PS3 slim the gap in between the fan and top case varies (because the top cover is not plane, but the fan is paralell to the ground)
At the max gap (the point of the circle closest to the PSU) is something like 1cm, and the minimal (at front) around 4mm

Aha, then it is OK. I will try this with 5mm holes tomorrow. Thanks :)

Just a couple of suggestions before the experiment :)

Dont use a drill bit for stone/concrete (this would be a disaster), the bests for plastics are the bits named HSS (for high speed steel), they devoures the plastic so you dont need to make any force, it gives you more precission

And for the protective metal sheets i was mentioning (to prevent scratches made by the HSS bit) i guess you can use a can of cocacola, or a can of tuna, etc...
You can cut this cans with normal scissors to have a metal sheet from them

And just incase you have "double side glued tape" at home... you can stick this metal plates to the plastic walls with the tape before drilling each hole

Dunno, the way how to use this protective metal sheets is something you need to imagine by yourself, but i suggest to try to use them because if the drill bit touches the plastic walls there is going to be scratches for sure and the whole experiment could be a disaster :)

I would put some wood below plastic, so I think that drill will not pass a lot beneath drilled plastic :)

The holes at the front are a different history though, hmmm... i never thought in this but looks like a good idea
And are different than the holes at the sides (this is another thing hard to explain, needs a drawing), and im realizing right now that allows to make them bigger (by removing only a bit of plastic and doing it in a easy way)
Actually... im thinking in the metal pieces of the antennas located exactly over this holes and are blocking a bit the airflow, i guess moving that metal plates antennas to other place (or rotating them) could have a good effect
But if you decide to do this keep in mind the geometrical shape of that metal plate antennas should not be changed ! (so dont bend them, and dont crop/saw them)
The geometry of the antenna is what creates the wireless waves... by changing them you could decrease the wireless intensity or frequency, and is going to have problems connecting wireless to wifi/bt

For completionism ;)

To cut the blue areas i think is better to use a cutting knife (instead of the drill), because this holes are easyer to cut and are only a few

I made some tests to see if the antennas fits there and they does, i can close the PS3 case with the antennas in that position, so there is no need to bend or crop them, is just a matter of moving them a bit, and to find a good way to keep them fit in place in the new position

To make fit the antennas there i had to rotate them, but i guess there is no problem rotating them because i guess are omnidirectional

I cutted holes :) but not much improvements. I got temps 67/69 at 28% fan speed. I think that holes above fan would be better improvement :)
Here pics.

Sorry to say but is not well made, the holes at the sides are not doing anything, you went trapped in the problem i was mentioning of the "double hole channel". Tomorrow i will make another drawing to explain why i say this

The holes at the front are fine though... so the small improvement in temperatures you noticed probably was caused by the holes on the front (only)
 
I think that fan doesn't produce enough negative pressure. Only direct hole above fan will be visible improvement. Or some extra fans to blow air into PS3 through these little holes.
 
This is the explain of why i say that every hole is "double"

The open area of every hole is a rectangle, if you look at it from inside the rectangle is in a "vertical" position

But if you look at it from outside there is another rectangle in a "horizontal" position
UT6MGE0.jpg

This is one of your photos where it can be seen the rectangle located in horizontal position has exactly the same size of the original (so it allows to pass the exact same amount of air than from factory)


And the reason of this.... is because are 2 different rectangles located in 2 diffrent positions :)
Actually, the geometry of that "holes" (i prefer to call them "channels" though) are like a cube
The air enters in direction bottom--->top and then the channels forces it to turn 90 degrees... so the air enters in the case in horizontal direction

That "turn" made by the channel causes noises, whith what you did the air enters better (without making that turn) so maybe noise has changed
But the amount of air is the same because the rectangle at bottom is the same !

Take another look in detail at where i located the circle at this drawing
qCBsmZX.jpg

The circle i painted is making that rectangles bigger
Because the goal is to transpass the plastic entirelly side to side... you drill from inside but the drill bit needs to get out at the other side
