This Single-Fan GPU Houses The 285W GeForce RTX 4070 Ti

The NVIDIA GeForce RTX 4070 Ti, as the third-fastest card in the company’s RTX 40 series lineup (ignoring the SUPER series), calls for some serious cooling requirements. Pretty much every card out there that houses this silicon comes in three fans, and are fairly sizeable chunk of metal that can barely fit into most people’s PC cases.

This modder, who goes by the name of u/TechTaxi on Reddit, decided to make the GPU fit in the smallest of spaces possible – by turning it into effectively a GPU designed for SFF (small form-factor) PCs. It measures just 173mm long and fills up just two slots (or 41.5mm). For reference, the RTX 4070 Ti you can buy off the shelf today almost universally comes in around 300mm in length, and most likely is three slots thick.

That being said, having a GPU this small does put into question how it dissipates all that heat – or any kind of underclocking/undervolting techniques is applied to prevent overheating. Furthermore, no tests have been performed to verify its thermal performance so far. The donor card is a Gainward GPU, and the modder believes that this cooler design should, on paper, be compatible with the SUPER variant of this silicon, as both silicon are pin-compatible.

Of course, this is not something you’ll ever get from a retail unit given that the cooler is likely not designed to handle this amount of heat. The most powerful NVIDIA GPU with single-fan designs from AIBs is the RTX 4060 Ti, which draws much less power than the RTX 4070 Ti, at just 160 watts (165 watts for the 16GB variant). However, the number of extra cores available on the RTX 4070 Ti may offer more performance even with the power draw reduced, and this may be the rationale that modders go far out of their way to mod GPUs like this one.

Pokdepinion: Come to think about it, that’s basically how laptop GPUs operate – so it might not be that crazy after all?
