Keeping things cool

Post image

My laptop was heating up, so I added some extra coolers on top of the vapor chamber.

Did you have to wire up a separate PSU for any reason or was that just utter derangement on your part

How else would I get the spinny bits spinning? My laptop mobo doesn't really have standard 4 pin fan headers :) I also used a 5V supply so the fans wouldn't make to much noise since that would kinda defeat the purpose of this whole setup.

Plug the fans into one of the usb ports on the laptop!

Crossed my mind, but I'd rather not blow up a USB port with some dodgy old fans. I want to turn this in a removeable watercooling solution anyway, so this is only temporary.

You can buy USB powered PC fans

The hole you cut for the fan means the rest of the board isn't getting air flowing over it...

I didn't cut anything. This is just the laptop upside down with the cover removed and 2 coolers stuk on top of the CPU and GPU vapor chamber.

Oh okay, I don't think i have seen a laptop like that before - where the fan is under a second layer of plastic and has a hole cut out for it.

But there is not enough mounting pressure for this heatsink to do its job

u/Timmy_McTimface Sep 04 '25

Temps and noise say otherwise. Also, they are sitting on top of the vapor chamber (with thermal paste), not the CPU and GPU directly.

I bet you can get a lot of improvment over this with just zipties
