Came across these today:

What's to stop you from putting these on the back? (Only thing is that if you attached it right to the heatsink, you're mixing copper and aluminum.
 But does it matter if they're not in the loop together?
 

@osb when have u ever seen a heat sink smaller than what it’s trying to cool? i’m looking at thermal tape to stick this https://www.amazon.com/dp...ncoding=UTF8&psc=1
 
might use multiple. PCB is roughly 288mm long and 120mm tall.  
 
@clovis any pics? idk even understand what that is. looks like I’m a copper plate with a copper block on it? if that’s what it is that doesn’t seem good for cooling. where the heat fins?
 

 
 
 Have you seen this before? It's a Backplate Waterblock, you clip on your gpu. Seems like they are quite new on the market.
 
 
The size is about 15 cm, but how big is the heat generating area on a Kingpin or ftw3 Backplate really?

I like that a lot. Curious on thermal tape.

Good news: The site lists prices in pounds. So no Customs fee.
Bad News: Website is out of stock.
 
The website only lists the outside of the tubing included as OD 4mm, that is going to make for some tiny tiny tubing.
