Noctua has released special NA-IS1 spacers for its fans.According to the manufacturer, the new products increase fan efficiency in certain usage scenarios.Image source: NoctuaThe company claims that the special spacers are designed to improve airflow in cases where fans have to draw air through various perforated surfaces, including radiators, mesh panels and filters.If a fan is installed very close to a perforated surface, turbulence can be created, and with it comes negative aerodynamic and acoustic effects.By adding 5mm between the fan and the obstruction, the NA-IS1 spacers can significantly reduce inlet turbulence, which will not only improve acoustics, but also help fans increase airflow, according to the developer.Laboratory tests show that the use of spacers not only increases airflow by 4.4 m3/h on average, but also reduces fan noise levels Noctua NA-IS1 spacers will be available in NA-IS1-14 Sx2 for 140mm fans and NA-IS1-12 Sx2 for 120mm fans.Black versions of the NA-IS1-14 chromax.black Sx2 and NA-IS1-12 chromax.black Sx2 will also be available.The company indicates that the NA-IS1 is compatible with all Noctua 120 × 25mm and 140 × 25mm fans.All versions of the NA-IS1 come with two spacers, anti-vibration pads, and a set of M3 and UNC 6-32 screws.A pair of NA-IS1 spacers costs $14.9 or euros, depending on the region. In addition to the NA-IS1 spacers, Noctua has also released the new NA-AVG2 anti-vibration spacers for 140mm fans.Like the NA-AVG1 spacers for 120mm fans, the new NA-AVG2 spacers are made of soft but very durable rubber to help dampen minor fan vibrations as well as reduce airflow loss between the fan and heatsink.The NA-AVG2 will be available in both traditional brown and chromax.black.A set of three pads will cost 9.90 euros or dollars.
A week after images of ASUS GeForce RTX 3080 Noctua OC Edition 10GB graphics gas pedal leaked, this novelty was officially introduced.Like the ASUS GeForce RTX 3070 Noctua OC Edition, the older model has a very thick cooling system with two 120mm NF-A12x25 fans that have a full stop feature.The GeForce RTX 3080 Noctua OC Edition 10GB uses NVIDIA's GA102-202 CPU with 8,704 CUDA cores, 272 texture blocks and 96 rasterization blocks.The gaming frequency of the processor is 1785 MHz.However, the chip was slightly overclocked, so in Boost mode its frequency is 1815 MHz.The card has 10 GB of GDDR6X memory with 320-bit bus support.There are two BIOS with quiet and performance modes and a set of external connectors consists of two HDMI 2.1 and three DisplayPort 1.4a.Also there are two 8 pins connectors for additional power.We recommend to use the power block with this gas pedal capacity from 850 W.The novelty is based on the ASUS GeForce RTX 3080 TUF Gaming 10GB printed circuit board.According to ASUS, GeForce RTX 3080 Noctua OC Edition 10GB is the quietest graphics card in its class.At low fan speeds, it is quieter than 16.8dBA.To compare, the noise level of regular graphics card in the same mode is 19.1 dBA.Picture source: Noctua With automatic fans speed control, typical noise level does not exceed 21.6 dBA (noise level of regular graphics card is 26 dBA).At average fan speed, the noise index is no more than 29 dBA (regular video card has 33.4 dBA).At the maximum speed of the \"propellers\" noise reaches 33.8 dBA (with the standard version - 42.4 dBA).Image source: Noctua Image source: Noctua Image source: NoctuaThe cooling system ASUS GeForce RTX 3080 Noctua OC Edition 10GB is not only quiet, but also very effective.In auto fan mode, the GPU temperature is an average of 3 degrees lower than that of a standard card, and the temperature of the video memory chips is as much as 14 degrees lower.At the maximum fan speeds the GPU temperature is equalized with the competitor, but the video memory is still better cooled - its temperature is on average 12 degrees lower.At the same time, the company notes that in general, the gas pedal cooling system reduces the working temperature of memory to 22 degrees more effective than competitors solutions.Image source: Noctua Image source: NoctuaThe dimensions of the ASUS GeForce RTX 3080 Noctua OC Edition 10GB is 306.2 × 144.8 × 82.6 mm.It will occupy four expansion slots in the computer case (officially the manufacturer indicates 4.1 occupied slots).About the price and availability of GeForce RTX 3080 Noctua OC Edition 10GB the company did not announce.
