Could a laptop use a two cpu coolers?

I raised this doubt just out of curiosity, so this is a hypothetical case.

For example, if we have a laptop, which does not work the screen and the keyboard is defective, we dismantle everything and only leave the mainboard of the laptop, could you use two CPU coolers for the CPU and the GPU of the laptop? You will of course have a housing adapted for it.

 

Possible but loads of potential issues

Mounting them on stock screw holes would be the first challenge. Clearance around the socket is another thing usually not present in laptops that may cause problems

A BGA soldered CPU would sit much lower than a desktop CPU so may need a sizeable shim. Even an old mobile socket would need a shim as it's lacking a heatspreader.

The pcb may not be reinforced enough to cope with the weight especially since most would be mounted on the underside and gravity would pull the mass downwards.

Youll need to match up the fan headers if you want the laptop to control fan speed, some laptops may even refuse to work if no CPU/GPU fan is detected.

The GPU may also need cooling on the memory and vrm chips if it's high end.

Also the OEM keyboard is not necessary, booting with a USB keyboard should be no problem (no different than booting with external screen with internal panel disconnected)

I'd keep the motherboard mounted in the shell of the base just to protect it cutting holes and openings as required

As you can see getting second hand OEM fans and heatsinks is the far easier option

 

Easiest method I have seen is using thermal glue and fitting the heatsink in a fashion that can be mounted to the frame.

Something more advanced is this...

Easily my favorite mod of all time, hooping to replicate it in the future in some amatuerish way...

 

The picture links for that mod are broken, too bad, I would have liked to see this mod

 

Works fine on two separate computers, must be a problem on your end...

 

Good to know I'll try another system I was using my phone

 

I suggest you maximize the airflow on the existing fans first, there will be noise trade-off but it's up to you what you want to prioritize. If that's not enough, invest on liquid metal thermal compound as long as you're not using aluminum heatsinks. If that's not enough, and you have defective laptop battery, you can try to use that to add a second fan like i did, you're lucky if the battery pack sits beside the gpu, but it's important to determine the right power source. I used USB 5 volts but it has some effect on the functionality of the other ports is hte power draw is too much, but typical laptop fans just have .40 amps so that's sufficient (mine uses .5 amps so thats 2.5watts so sometimes it draws too much power if you have other usb devices connected). you have to study the air intakes and separation of airflow of the 2 fans to be more efficient.

Here's what i did a few years ago but it's been through even more changes and works better even at 4ghz stable, but i normally meet the power limit of my power brick so it tends turn off when it does, by battery pack supplies more power so it's more stable when i use it.
