I am looking for a means of cooling ANY low-profile graphics card - something like a GTX1650 or RX6400. The availability of a cooler will determine the choice of GPU. It's mainly an appearance thing. I'm not after a super high-end card - just one I can use at 1080p.Define low profile. Once you go custom level water-cooling, you eventually end up with a 1 slot card...in some situations a 1.5 slot card (with block slapped onto it). Are you referring to another axis, in terms of low profile? Also, what GPU are you working with? Not all blocks will fit every card, due to clearance issues on PCB's from one AIB maker to the next.
