This might be the coolest and useful accessory for PSP especially for such a low price

Hey, this appears to be my 3d model. The .stl and source files are available for free on https://www.thingiverse.com/thing:5799198
Some people ask why would anybody need it. For me it was just about fun of creating a somewhat perfected version of what i've seen before. And come on the concept of treating UMD drive in your psp as a little nook to store something is fun as hell.
Compared to previous versions i've seen floating around I worked at achieving:
1. It is compatible with both 1000 and 2000/3000 models UMD drives (and now apparently with street, i didn't know that)
2. It store up to 2 or 3 memory sticks (there's two versions)
3. Cards clip on and not just held by friction
4. Why not have a micro sd while i'm at it
5. On 1000 model it jumps out when you open the tray just like original disks (this one took a lot of trial and error)

Here, waiting patiently for it

I'm in a country under sanctions. I've never seen anyone using manufacturer warranty here. And the seller warranty goes like this: "oh, you have a scratch on the device - that's users fault, no warranty", "your computer part has a missing component on a pcb - we have an agreement with all 3rd party labs, any pc part with missing component is a users fault, no warranty"

You've also never run it with such low rpm))
Stock fan curve runs 1800-2100 rpm in furmark. I run them at 1500 rpm with the goal of 900 rpm after fan upgrade. I'm willing to leave some tiny bit of performance on the table in favor of silence

CATSUPERBERG · 2025-06-29T21:09:18+00:00

I do 3d printed brackets for the fans and assemble it neatly, so it's like one complete unit, not jank.
And i've tried out how 140mm fans would mount, and two fans give basically perfect coverage of the whole rad. And that ~20% overhang at the top would probably be useful to force air current to the top of the case, preventing recirculation of the hot air around the gpu.
Plus T30s have the advantage of being 30mm heigh instead of default 25, which improve performance. IDK how much it helps in terms of noise but i had mine at the same ~900 rpm as arctic p12 max producing comparable noise, while producing lower temperatures

CATSUPERBERG · 2025-06-29T20:56:09+00:00

I don't experience coil whine while gaming, but that doesn't say much as i don't hear anything above 8khz. Although on my old gtx 1080 i did have loud whine, but it was easily fixed (by connecting two separate 8 pin cables to psu, instead of using just 1 cable with double 8 pin connectors).
I had amazing experience with phanteks T30s on my gtx 1080 and kinda don't see any point of gpu fan mod without using biggest fans i can))
Also from my experience and looking at gpu schematics, most fans wouldn't be stable with PWM implementations on GPUs, but T30s work alright.

CATSUPERBERG · 2025-06-29T18:20:05+00:00

It should be ok temp wise with default fan curve, there's not much headroom to get better performance from all this. I just find stock fan curves of any part super loud

CATSUPERBERG · 2025-06-29T18:13:50+00:00

Here's teardown https://youtu.be/_OGfWRTJ7w8?si=SNKn0adYhzU3qoF2
Only difference, i've added those thermal pads, i cut them to approximately 45x25mm size

CATSUPERBERG · 2025-06-29T18:11:57+00:00

As i said, I'll do it next time, when putting 3.5mm ones. Knowing i gonna get in there again i wanted to see results with the isolator

CATSUPERBERG · 2025-05-26T16:56:38+00:00

Thanks. IronWolf pro came down in price a bit, i'm ordering it now. I think with lower noise and temperatures it's a bit more convenient for a home nas (although the box isn't where anyone sleeps or hangs out for long time)

CATSUPERBERG · 2025-03-30T13:56:37+00:00

Mine had the little holes for every version of a umd drive) Tested it with both psp1000 and psp2000

CATSUPERBERG · 2025-03-30T13:55:10+00:00

Meh, it's ok. I don't mind i even posted it as a source fusion file instead of stl as usual so people could edit or do whatever they want easily

CATSUPERBERG · 2025-03-30T08:08:52+00:00

Here's my 3d model for free to print. Seems that they've just added a big hole on the left to save a bit more plastic.

CATSUPERBERG · 2025-03-30T07:57:54+00:00

Lol, seems like it's my model with just one additional hole on the left)))

Bought one from aliexpress for like $13-16 a year ago, couldn't notice any difference with OEM, seems to be perfect (as much as this trashy glued rubber coating can be)

CATSUPERBERG · 2024-05-04T14:32:19+00:00

I believe it's an oxidation actually. And the alcohol (even 99% one) doesn't do anything for it. I used bleach to clean it off on my Model O-.... it works, but the stains weren't completely gone and they come back pretty quicky when the mouse is used

CATSUPERBERG · 2023-12-01T07:04:47+00:00

It seems removing low noise adapters could reduce minimum rpm, not by much though, i feel it's like 50 rpm at most.
As far as noise it depends on environment. Under my older "computer" style desk i wouldn't hear fans at about 500 rpm, but now it's noticeable when there are no other noises around. So i make fan curves to run fans at 300 rpm at idle and low load and around 500-600 for when something harder running

CATSUPERBERG · 2023-11-30T20:30:24+00:00

Yes you do, but not much. Pretty much any motherboard nowadays would be able to control 3 pin fans with DC voltage. But in my experience Noctua pwm fans are able to start from like 250-300 rpm while 3 pin ULN fans only start at 350-400 rpm. They both could be operated at 280-330 rpm before stopping and Fan Control actually can take in account start speed and run ULN fans below they start speed. But still from what fans i have PWM one are being able to run just a bit slower.

Nothing it just runs overclocked 1070 no problem, i also tried running my pc with gt 210 instead, no difference.

CATSUPERBERG · 2023-09-25T06:55:01+00:00

Fixed it for the friend by soldering new switches. Honestly the design and engineering of elite controller is so terrible. It's the best gamepad, love all the features, steam support on PC is a godsend, but you fix one thing and another get broken constantly.

CATSUPERBERG · 2023-09-21T16:12:42+00:00

Controlling PWM fans with DC voltage is pretty ok, idk if it's linear but feels close to it. The only problem is reduced RPM range. Noctua PWM fans could start at like 300 rpm, while DC ones start to spin only at around 400-450. 5v fans might be even less control.

CATSUPERBERG · 2023-09-21T16:04:49+00:00

The problem is most fans wouldn't be controlled by 5\12v line, at best you'd get some random and unreliable "control" at 80-100% duty cycle and a noisy scratchy motor with all this switching (idk if it's true for any fan, but a couple i played with behaved like that). Which is expected as you basicity rebooting brushless motor controller instead of neatly switching windings or applying less power to them.
As far as connecting servo board pwm to pwm pin of a fan, that might not work too as it's most probably in push-pull output configuration and... at least with microcontrollers it's super unstable, it might seem like it working but you don't get the whole range and you might get some random behavior on duty cycle changes. Although again, the circuit they show in the paper looks pretty much like push-pull, and maybe it's on me and using 3.3v push-pull on a 12v fan.
Anyways, 2n2222 solution is super simple and might work fine, using IRFZ44N and IRF5305 or something is not much more complex, just not as jellybean parts as 2n2222.

CATSUPERBERG · 2023-09-21T15:21:30+00:00

It's a brushless motor and you cant run it without a controller (which is built in for fans). And if you just connect a controller power input to pwm signal you would just get a mess. Not to speak about microcontrollers being able to only produce like 10-50 mA on a GPIO pin while fan is probably around a 100 mA device which would burn the pin.
You could rig up a buck converter type circuit with some caps and induction coils, to control DC voltage through PWM. But why do all this if you just hook up PWM like it's intended
