Dự án này tập trung vào việc đưa bo mạch chủ PS3 Slim đời CECH-25xx vào vỏ máy tính để cải thiện hiệu năng tản nhiệt và tính thẩm mỹ. Đây là đời máy lý tưởng nhất vì có thể Jailbreak hoàn toàn và không cần ổ đĩa vật lý để chạy ứng dụng.
1. Tại Sao Nên Mod PS3 Vào Vỏ PC?
- Tản nhiệt tối ưu: Sử dụng các khối tản nhiệt (Heatsink) lớn hơn giúp CPU và GPU chạy mát hơn đáng kể.
- Thông thoáng: Bo mạch không còn bị gò bó trong vỏ nhựa chật hẹp, tránh tích tụ nhiệt cục bộ.
- Chống chập mạch: Loại bỏ khung thép nguyên bản của PS3 (vốn dễ bị rỉ sét theo thời gian gây chập cháy).
- Bảo trì dễ dàng: Thay pin CMOS hoặc vệ sinh máy cực kỳ nhanh chóng.
2. Chuẩn Bị Bo Mạch (PS3 Motherboard)
Dòng CECH-25xx được chọn vì:
- Hỗ trợ Jailbreak để chơi game trực tiếp từ ổ cứng (HDD).
- Mạch điều khiển ổ đĩa được tích hợp thẳng vào bo mạch chủ, giúp máy vận hành ổn định mà không cần gắn ổ đĩa Blu-ray.
- Kích thước bo mạch: Rộng 257mm x Cao 260mm.
3. Chế Tạo Tấm Gắn (Adapter Plate)
Để bo mạch PS3 khớp với các chân ốc của vỏ PC chuẩn ATX, bạn cần chế một tấm nhôm trung gian:
- Kích thước: 305mm x 250mm x 1.5mm.
- Định hướng: Xoay các cổng USB của PS3 hướng ra phía sau (khu vực IO Shield của PC), còn các cổng nguồn/HDMI hướng về phía trước vỏ case.
- Mẹo khoan lỗ: Sử dụng một bo mạch chủ PC hỏng đã mài phẳng mặt dưới để làm khuôn lấy dấu các lỗ vít chuẩn ATX lên tấm nhôm.
4. Hệ Thống Tản Nhiệt Tùy Chỉnh (Custom Cooling)
Đây là phần quan trọng nhất của bản mod:
- Đế đồng (Base-plate): Cắt từ tấm đồng dày 3mm dựa trên khuôn tản nhiệt của đời CECH-3002.
- Ống dẫn nhiệt (Heatpipe): Hàn các ống heatpipe và lá tản nhiệt trực tiếp vào đế đồng để tăng diện tích giải nhiệt.
- Lưu ý kỹ thuật: Một số tụ điện có thể bị cấn vào đế đồng tản nhiệt. Bạn cần xả mối hàn và dời tụ điện sang vị trí lân cận bằng dây nối dài thay vì cắt gọt đế đồng.
- Cảnh báo: Do tản nhiệt tự chế chỉ có 2 điểm tựa, hãy tránh va đập mạnh hoặc làm rơi vỏ Case vì có thể làm mẻ góc chip CPU/GPU.
5. Hệ Thống Kẹp & Cố Định (Clamping)
Sử dụng các trụ đồng (brass spacers) có kích thước khác nhau cho CPU và GPU để đảm bảo áp suất ép tản nhiệt đồng đều:
- Trụ CPU: Cao 14.5mm.
- Trụ GPU: Cao 16mm.
- Kết hợp với các tấm I-clamp nguyên bản của PS3 để giữ chặt khối tản nhiệt vào bo mạch.

THE IDEAThis mod is to basically develop a PS3 slim model CECH-25xx motherboard adapter plate and wiring adaptors that are able to be transplanted between different PC cases with no modification to the PC case and only a few minor modifications to the PS3 motherboard.
REASONS
- Have a bigger style heatsink so that the PS3 CPU and GPU runs cooler.
- Allow the motherboard exposure to more air rather than being in close proximity to a heated metal chassis.
- Motherboard steel chassis’ rust and the rust particles fall on to the motherboard and cause shorts.
- Easily change the motherboard clock battery.

PS3 MOTHERBOARD
The chosen PS3 motherboard will be from CECH-25xx model PS3 slims due to being able to be jailbroken therefore they can play games off of the hard drive.
Also the disk drive circuit board is incorporated into the motherboard therefore it does not require the actual disc drive to be attached to launch games and apps unlike all earlier model CECHAxx to CECH-21xx PS3s that do.
Dimensions:
The PS3 CECH-25xx model motherboards measure about:
Width=257mm (Including USB port to rear ports)
Height=260mm
ADAPTER PLATE
Details:
The PS3 motherboard is to be mounted onto a custom made ATX aluminium adapter plate measuring 305mm x 250mm x 1.5mm thick. The purpose of the adapter plate is to combine the standoff holes from the PS3 motherboard and PC case onto the one plate.
Orientation:
The motherboard will be oriented so that the USB ports will be accessible through the PC case rear IO port area and the rear ports on the PS3 motherboard will be facing toward the front of the PC case.
Procedure:
I used the PS3 and PC motherboards as templates to drill the standoff adapter plate holes depending on the motherboard version. The basic process is as follows:
1. Clean the aluminium plate edges of any burs
2. Clamp the motherboard in place
3. Use a bench drill-press to lightly mark the standoff holes using the following drill sizes:
3mm – PS3
3.5mm – PS3
11/64 4.35mm – PS3
4mm – PC
4. Drill the PS3 clamping hardware holes – See the text following this section for more info.
5. Remove the clamps and motherboard
6. Drill the marked holes all of the way through using the following drill sizes:
3mm – PS3
4mm – PS3/PC
7. Remove the burs from the drill holes
NOTE: For the best results in standard ATX cases position the PS3 motherboard so that the PS3 motherboard top edge sits 10mm lower than the PC motherboard top edge. This is so that one of the PS3 motherboard standoff mounting hole bolts don’t collide with a PC standoff screw.
Example PS4.

Option 1 – Not Recommended
With the PS3 motherboard sitting on standoffs the shorter the better, using a bench drill and a 6.5mm drill bit it is possible to drill straight down through each of the four motherboard clamping hardware through-holes.
NOTE: ONLY USE IF you cannot make the spacers listed in option 2 as this method is less accurate.
NOTE: If the drill grabs the motherboard clamping hardware hole it will widen out the hole making the centre mark less accurate.
NOTE: If the drill is bent it may result in out of place centre markings. The higher the standoffs the worse the issue can be.
Option 2 – Recommended
For the most accurate standoff hole locations in the adapter plate get faulty PS3 and PC motherboards. Then grind the motherboard bottom till all of the SMD components and protruding through hole component legs are gone and the motherboard bottom surface is flat.
WARNING: YOU SHOULD WEAR A FACE MASK TO STOP INHALING PARTICLES THAT MIGHT CAUSE INJURY OR ILLNESS.
Grinded PS3 motherboard.
To make sure the clamping bolts as close to centred as possibly on the aluminium adapter plate you need to create a custom spacer 6.5mm wide with a 3mm hole drilled through the centre. Place the spacer in each of the four motherboard clamping hardware through-holes before drilling a 3mm hole through the adapter plate.
NOTE: The 3mm drill hole in the middle of the 6.5mm spacer must be perfectly centred within the spacer.
COOLING
Processors:
WARNING: Because the processor heatsinks will only be supported at two points if the PC case is dropped or falls it’s more then likely the heatsinks will wobble and break one or two corners off of the processor dies thereby killing them.
I have used the GPU heatsink from a CECH-3002 PS3 as a template to cut the perfect heatsink base-plate shape from 3mm thick copper plate. I cut the fins off of the CECH-3002 GPU heatsink leaving only the base-plate. Then I sanded and filed both sides so that they are reasonably flat. I then clamped the CECH-3002 GPU heatsink base-plate to the 3mm copper plate then drilled the two mounting holes and marked the outer base-plate shape. Then bolted the CECH-3002 GPU heatsink base-plate to theother side and once again mark the outer shape. Next I cut, filed and sanded the 3mm copper plate till it matched the CECH-3002 GPU heatsink base-plate shape. I then shortened the overall length of the base-plate so that they don’t collide with the four nearby inductors/coils that are grey in colour that can be seen in a picture below.
Finally I soldered a heat pipe heatsink to it. I have build two of these heatsinks.
Modified CECH-3002 GPU heatsink base-plate. Ready to template.
Final copper base-plates.
Final heatpipe heatsink soldered to base-plate.
NOTE: With the base-plate shape that you see one of the electrolytic capacitors will collide with the CELL/CPU heatsink base-plate. As a simple workaround I will snap-off or de-solder this, move it over slightly and extend the capacitor legs. I prefer this method over modifying the base plates.
Clamping
Connect the heatsink to the adapter plate using official clamps and created custom spacers.
NOTE: On 21xx\25xx model PS3s the IHS’s should not be removed as the glue used to attach them is stronger then on previous PS3 models. Attempting to remove them can damage the chips.
IHS’s Removeable:
Order:
1. 3mm bolt
2. Adapter plate
3. Inner brass spacer. With centre 3mm threaded hole.
CPU: 14.5mm (H) x 6mm (W)
GPU: 16mm (H) x 6mm (W)
4. Outer brass spacer. With centre 6.3mm (1/4) hole through the centre.
CPU: 7mm (H) x 8mm (W)
GPU: 7mm (H) x 8mm (W)
5. PS3 I-clamp.
6. PS3 I-clamp motherboard backing plate.
7. PS3 motherboard

2. Adapter plate
3. Inner 2.5mm brass standoff.
CPU: 14.5mm (H)
GPU: 16mm (H)
4. Outer brass spacer. With centre 5.5mm (1/4) hole through the centre.

5. PS3 I-clamp.
6. PS3 I-clamp motherboard backing plate.
7. PS3 motherboard
8. Heat sink base-plate
9. 2.5mm bolt.
Without clamping hardware.
WARNING: Care must be taken when inserting or removing the motherboard as it is more likely to flex when doing so due to the spring state of the I-clamp. Proper procedure after placing the motherboard is to mount the heatsink then tighten the four heatsink screws. Next screw in the rest of the motherboard to adapter plate standoff screws. Removing the motherboard should be done in the reverse order.
Backing Plates:
The metal chassis clamp backing plates have been removed from the chassis and hot glued onto the motherboard.
Fan:
I have made up a custom cable to allow the PS3 to run 4 pin PC fans. The PS3 does not have the fan RPM wire that typical PC fans have so I have left that pin unconnected as can be seen in the following picture.

CLEARANCE ISSUES
Working out the heatsink clearance:
Since the PS3 GPU IHS(Integrated Heat Spreader) top is higher then the PS3 CPU IHS. I will be using it’s measurements for my calculations.
The height of the PS3 GPU IHS top above the PC case standoffs will be 1.6mm (adapter plate thickness) + 10mm (PS3 motherboard standoffs) + 1.5mm (PS3 motherboard) + 4.6mm (PS3 GPU IHS top) = 17.7mm.
The height of the Intel CPU IHS top above the PC case standoffs is 1.5mm (PC motherboard) + 8mm (CPU IHS (H) above motherboard) = 9.5mm.
To find out if the chosen heatsink will still fit height wise into the PC case you must subtract 9.5mm (PC CPU core height) from 17.7mm (PS3 GPU IHS top) = 8.2mm the PS3 GPU IHS top is higher than PC CPU core height.
Then take 8.2mm off of the PC case CPU heatsink clearance specification to get the maximum height value for the supported case heatsink clearance height specifications and choose a cooler height of that amount or less.MEASUREMENTS
Just some CECH-25xx measurements that might help someone out.
- 4.6mm – GPU IHS top height above motherboard
- 3.15mm – CPU IHS top height above motherboard
- 1.45mm – Difference between the IHS top levels
- 2.25mm – GPU IHS thickness between the core and the IHS Top
- 1.55mm – CPU IHS thickness between the core and the IHS Top
WHAT I STILL NEED TO KNOW
