eBay Large vapor chambers on Ebay

[thewizzard1]

Just a quick link for those interested:
https://www.ebay.com/itm/Celsia-Cop...1DR007A10-w-FCT-730-Thermal-Tape/291379683007

I'm neither affiliated nor have I done previous business with the seller, but I am picking up one or more of these for myself.

Nice

Added benefit is that it is Celsia made, so it is a quality one.

I dont see any numbers saying how much watts it can move. Do you have any info?

None that I see, but I just purchased 2 anyways. I'm going to guess between 75 and 150W, judging by size.

What do people do with these things?

Basically, move heat somewhere else.

More specific?

If you put a heated element on one side of the vapour chamber (ie. CPU/GPU) and a heatsink on the other end, the vapour chamber would very efficiently move the heat from one to the other.

It's also a heat *spreader*, allowing for a normal sized chip to sink heat into the entire surface it's attached to, instead of mostly radiating from the center. The vapor chamber's working fluid (acetone mostly) is far more thermally conductive than most other materials.

Here's some info on the thermal interface:

Thanks. Not sure if these things are easy to bend or not. So bought 5 for experimentation.

I would assume they are meant to be used flat, given the design. That's how I intend to use mine.

Mine arrived a few days ago. See tape and Apple Magic Keyboard 2 in the picture for approximate dimensions/scale. This one weighs 307.3g (10.8oz). The other side is completely covered with the FCT-730 thermal conductive tape. The small cutout I guess originally is for some tiny device like a laser diode.

Nice, what are your plans for it?

I'm looking forward to seeing you guys experiment with these.
