neat trick: Remember when the best graphics cards only took up one slot in your computer case? Long gone are those days when even low-end cards take up a lot of space in the back of your computer. But what if you could cut the RTX 4090’s volumetric footprint by more than half? That’s what Optimum Tech has done with an aftermarket GPU waterblock.
Today’s high-end graphics cards are not the slim components they once were. With fat heatsinks and fans, GPUs like Nvidia GeForce RTX 4090 Converting the apartment into a townhouse apartment. However, the YouTube channel optimum technology (OT) Use a water-cooling device to turn the Nvidia behemoth into a paper-thin card.
Optimum Tech said this probably isn’t an ideal solution for most PCs, but water cooling is a bit of a sweet spot anyway. However, he said the smaller size could be useful in enterprise server applications. However, OT plans to install the card in its mainframe to see how it performs compared to its current setup. For the time being, it was played from an open bench.
The mod used is Alphacool ES water block. It’s only compatible with a few RTX 4090 models. Optimum Tech used an iChill Inno3D card in this case. The conversion to a water-cooled GPU resulted in a card that fit easily into an ITX case – at just 210mm long and thin enough for a single case slot.
While testing it on an open bench, Optimum Tech found that performance was on par with other alternatives like MSI’s Supreme Liquid X. It ran God of War and Control at frame rates above 100fps with GPU heats of around 53 degrees. Celsius only. However, the performance inside the case can vary widely. Optimum Tech recommends running it in a dual radiator setup.
Again, Alphacool designed this water block to reduce the size of the graphics card and fit more in the rack. However, nothing is stopping enterprising builders from incorporating the mod into existing or upcoming rigs, as OT intends to do soon. The block is being sold for $166.36 From Australian retailer Aquatuning.
