NVIDIA GeForce RTX 3090 Graphics Card Cooling & Design- Next-Gen NVTTM Founders Edition Design

NVIDIA has developed one of their best and most powerful Founders Edition cooling design to date for the GeForce RTX 30 series graphics cards. NVIDIA explained that higher performance requires a new form of cooling solution and as such, it has prepared a unique cooling solution for its next-gen cards which will keep GPUs running cool while staying quiet by utilizing several new & existing tech.

The Founders Edition cooling makes use of a full aluminum alloy heatsink which makes use of a hybrid vapor chamber with dual-sided axial-tech based fans. The cooler heatsink is coated with a nano-carbon coating and should do a really good job at keeping the temperatures in control.

The design is interesting in the sense that not only does it goes all out with a fin and heat pipe design. This is the first design of its kind since the original Founders Edition GeForce GTX 780 that makes use of a much larger heatsink area.

It also comes with a unique fan placement, one on the front and one at the bottom. This push & pull fan configuration which as it is referred to is said to push heat out of the exhaust vents much more effectively. There will be some air that will be blown out inside the case from the back of the card itself but that shouldn’t be a major cause of concern as modern CPU Air or Liquid coolers do a really good job venting out air from within the case.

Acoustically, the new Founders Edition design is quieter than traditional dual axial coolers, while still delivering nearly 2x the cooling performance of previous-generation solutions. The aforementioned NVLink and power design changes help here, creating more space for airflow through the largest fin stack seen to date, and the larger bracket vents improve airflow in concert with individually shaped shroud fins. In fact, wherever you look, every aspect of the Founders Edition cards are designed to maximize airflow, minimize temperatures, and enable the highest levels of performance with the least possible noise.

NVIDIA GeForce RTX 3090 Graphics Card PCB & 12-Pin Power Input

One of the biggest changes on the Founders Edition GeForce RTX 30 series graphics cards is the PCB design. The GeForce RTX 3090 & GeForce RTX 3080 comes with a unique & compact PCB package that is unlike anything we’ve seen in the consumer space before. But being compact doesn’t mean that the cards don’t pack a punch. There’s some serious horsepower on these compact PCBs that NVIDIA has designed.

The PCB features over 18 power chokes which put it is a more premium design than the flagship non-reference RTX 20 series cards. The GeForce RTX 3080 is powered by an 18 phase design that is insane and designed to be overclocked with unprecedented GPU overclock headroom that most users can leverage from to gain even faster performance.

In addition to that, GeForce RTX 30 series Founders Edition cards will be featuring the 12-pin Micro-Fit 3.0 power connectors. These connectors don’t require a power supply upgrade as the cards will ship with bundled 2x 8-pin to 1x 12-pin connectors so you can run your latest graphics card without any compatibility issues.

The placement of the 12-pin connector on the PCB is also noteworthy. It is placed in a vertical position and judging by the PCB design, we can tell why NVIDIA moved to a single 12-pin plug instead of the standard dual 8-pin design. There’s limited room on the PCB to do stuff and as such, it was necessary to go for a more small and compact power input.

NVIDIA GeForce RTX 3080 Graphics Card Price & Availability – Both Custom & Reference Designs at Launch

The NVIDIA GeForce RTX 3080 is being announced today and will be launching to consumers on the 17th of September, 2020. The first wave of graphics cards to hit the market would be the reference Founders Edition variant which will cost $699 US. The NVIDIA GeForce RTX 3080 will feature a price of $699 (MSRP) however custom models will vary depending on their design and the extra horse-power that they have to offer.NVIDIA GeForce RTX 30 Series Performance 1030x445 16

There aren’t any performance numbers that NVIDIA is sharing right now but from what has been showcased, the GeForce RTX 3070 is faster than an RTX 2080 Ti, the RTX 3080 is a good bit ahead of the RTX 2080 Ti and the RTX 3090 is about as much as 50% faster than the RTX 2080 Ti which is very impressive for the full lineup stack. The NVIDIA GeForce RTX 3080 itself is twice as fast as the RTX 2080 and is considerably faster than the RTX 2080 Ti making it a perfect 60 FPS 4K gaming graphics card.
