Arctic Introduces Quiet Calm RGB Case Fans with Passive Mode

ARCTIC, today introduces two new semi-passive case fans. A special 0-decibel mode enables completely silent operation when power is not needed. The P12 PWM PST 0 dB fans are available in two different variants, with analog RGB lighting as well as digital A-RGB. Clever feature for silence lovers: The new semi-passive case fans switch to passive mode when the PWM signal falls below 10 %. This allows silent operation at low load while guaranteeing the highest performance when needed.

At full speed, the hydrodynamic sleeve bearing and the new, rubberized contact surfaces reduce noise levels to a minimum. Plus, form has been considered as well as function: twelve RGB LEDs and a transparent rotor provide even, rich illumination. Thanks to high static pressure, the P12 PWM PST 0 dB fans guarantee efficient cooling, even with increased air resistance. An integrated Y-splitter for fan and RGB connection also make them easy to combine.

Gigabyte Preparing Passively Cooled AMD X570S Motherboards

AMD introduced their X570 chipset back in July 2019 to coincide with the launch of Ryzen 3000 processors. The X570 chipset consumed more power than previous chipsets and required a dedicated cooling fan on most boards which were often noisy or unreliable. AMD appears to be preparing an updated more efficient X570S silent chipset with passive cooling. Gigabyte has recently submitted eight new motherboards to the EEC which appear to feature the new chipset. The specific models submitted include the AORUS MASTER, AORUS ELITE AX, AORUS ELITE, AORUS PRO AX, AERO G, and GAMING X. It remains to be seen if all of these models make it to market and whether or not other manufacturers are preparing new boards.

Passively Cooled RTX 3080 PC Comes With A Few Compromises

The NVIDIA RTX 3080 is a 320 W TDP card making it impractical for conventional contained passive cooling solutions. Commercial passively cooled cards such as the GTX 1050 Ti, and GTX 1650 Ti all come in with a TDP of less than 100 W and even then require large heatsinks. Mical Wong, the founder of Turemetal a company specializing in passively cooled computers has managed to create a passively cooled PC with an RTX 3080 and Ryzen 5 5600X. The PC features the companies flagship Turemetal UP10 case.

The system booted but was unusable at stock settings with the RTX 3080 quickly overwhelming the cooling system when running at 100%. The GPU reached 87 degrees Celsius within minutes when running Furmark with a total system power draw of 410 W. The Turemetal UP10 is only officially rated for 300 W system cooling so the fact that this worked at all is quite impressive. With some CPU, and GPU configuration and power limiting, it would appear feasible to create such a system assuming you could afford it.

Calyos Unveils NSG Passive Cooling Kit for Thermaltake Core P3

Heatpipe cooling expert Calyos unveiled a passive-cooling kit for the Thermaltake Core P3 chassis. The kit mounts on to the panel bolts of the Core P3, and is an elaborate passive cooling heatsink, from which two sets of heat pipes make their way out. One of these mount on to the CPU (supports all modern socket types), and the other to a graphics card. The kit can handle thermal loads of up to 100W TDP for the CPU, and up to 180W TDP for the graphics card. That's enough cooling for a machine with a Core i7-6700K processor, and a GeForce GTX 1080 graphics card. Calyos will unveil this kit at its 2017 International CES booth.

Raijintek Unveils its First Passive Liquid Cooler

Raijintek unveiled its first liquid cooler that works without a prime-mover for the coolant (i.e. no pump). Further, its radiator lacks fans (i.e. no power, no noise). This closed-loop cooler works in the same principle as a heat pipe, with a combination of convention and phase-change doing the heavy lifting of heat-transfer. Heat from the source (your CPU) causes the special coolant to change phase to vapor, move to the heat-exchanger (radiator), where it condenses back to liquid, and flows back down to the block. We saw this contraption in action, and we can tell you that it works. It is ready for the real-world. Raijintek spent vast amounts of R&D budget developing this technology, and has patented it in most markets. We could see the first products based on this technology very soon.

Thermalright Teases HR-22 Passive CPU Heatsink

Thermalright is working on a massive new CPU heatsink, so massive, that it won't leave much room to strap a fan on. Pictured below, the new HR-22 is [intended to be] a passive CPU cooler with a large aluminum fin heat dissipation area, to which heat from the base is conveyed by eight 6 mm-thick nickel-plated copper heat pipes. Should you decide to use fans, with a rectangle fin profile, the cooler appears to allow you to strap 140~120 mm fans on its longer sides, and 80 mm fans on its shorter ones.

Thermalright is calling the HR-22 its next masterpiece. Said the company in its Facebook post, "Thermalright's signature model the HR-02, has turn the impossible to possible and shown the world the power of passive cooling. Now we introduce to you our next masterpiece, the HR-22." The new cooler is slated for 2013, we expect the company to use CES (early-January) as its launchpad.

XFX Gives Radeon HD 4650 Passive Cooling

Barely months into being an ATI add-in board partner, XFX refuses to be a newbie to the scene. After starting off the proceedings with non-reference designs for most of its initial product lineup, XFX adds yet another of its own designs to its small yet formidable ATI Radeon HD 4000 series: a passive-cooled design for an HD 4650 model.

Pictured by ATI-Forum at the ongoing CeBIT event, the XFX Radeon HD 4650 silent keeps up with XFX' black and red colour scheme. The PCB stays black, so does the heatsink over the GPU. Two heatpipes convey heat from the heatsink to a dense array of aluminum fins at the back of the card. One can expect reference clock-speeds for the card, considering its USP mainly is its silent cooling, and not exactly its cooling efficiency to aid overclocking. XFX may announce this card shortly.

BFG Quietly Slips in a Passively Cooled 9800GT

First reported to Fudzilla, US online retailers, and, have listed a passively cooled 9800GT based graphics card from BFG. Although there has been no official announcement, it has now also appeared on the companies own website named as the 9800 GT 512MB PCIe 2.0 with ThermoIntelligence Passive Cooling Solution. With a part number of BFGE98512GTHE, the card sports a quad heatpipe cooler mounted on the back of the card, as is usually found with most passive cooling solutions, though BFG seems to have done away with any memory and voltage regulator cooling. The card has no factory overclock so runs at the reference clocks of 600 MHz on the core, 1500 MHz on the shaders and a memory clock of 1800 MHz. Despite the card being sold as passively cooled, it is interesting to note that BFG has stated in the card's system requirements, "System chassis intake airflow greater than or equal to 25 CFM being directed towards the graphics card." Current pricing puts the card in at around $160 (US) with what would appear to be immediate availability.
