Noctua, an Austrian company known for its high-end air CPU coolers has announced that it will be offering up alternatvie mounting kits to users of its low profile NH-L9a cooler that have incompatible motherboards. Certain mini-ITX motherboards that place components on the back of the motherboard around the processor socket are incompatible with the company’s existing SecureFirm 2 mounting kit because the backplate cannot be installed.

The new alternative mounting system for the NH-L9a CPU cooler uses Noctua’s NM-APS3 spacers that go in place of the standard backplate. The spacers go in between the motherboard and screws, but are small enough to not run into any components installed in the area normally reserved for a CPU backplate. Two such boards that Noctua has found to be incompatible are the mini-ITX AsRock FM2A75M-ITX and AsRock FM2A85X-ITX.

Users with an incompatible motherboard and NH-L9a cooler can obtain the alternative mounting kit for free by contacting Noctua’s customer service line and providing them with a proof of purchase (scan, photo, or electronic invoice) receipt for both the Noctua cooler and an incompatible motherboard. Additionally, Noctua will be including both the standard SecureFirm 2 and alternative mounting kits in the retail NH-L9a cooler box from now on.

It is nice to see Noctua continuing its tradition of good customer care. They many not be as popular as other cooler vendors in the US but it seems they are a company willing to go the extra mile for its enthusiast customers.

Having a silent system without fans is a noble goal, but CPUs generally need at least one. A new heatsink from Silentmaxx called the TwinBlock is designed to passively cool processors up to approximately 100W. Supporting sockets 774, 775, 1155, 1156, 1366 on the Intel side and 939, 940, and AMD 2/3 for AMD processors, it is compatible with just about any processor. The TwinBlock is, in a word, massive. Weighting in a just over 3 pounds, the heatsink measures 210mm (B) x 135mm (D) x 160mm (H) mm. It features a copper base with 10 heatpipes that connect to two aluminum fin arrays.

Interestingly, FanlessTech pointed us to a new computer build – the Fanless I-850 Gamer – that the company is planning to use the passive heatsink with to create a silent gaming PC. The PC can be equipped with up to an Intel Core i7-3960X Sandy Bridge-E processor and up to either an AMD 7970 or NVIDIA GTX 670 graphics card. The processor is cooled using the TwinBlock cooler while the GPUs are using custom coolers that should only kick on the fans over long gaming sessions or folding. The Fanless I-850 starts at 1279,00€ for the base configuration.

It is possible to buy just the heatsink, however. The Silentmaxx TwinBlock cooler can be yours for about $120 USD (€ 99.90 inc. VAT). More photos of the cooler are available below, and you can read more about the cooler on the SilentMaxx website.

Sandia Shows Off Prototype of Its Impeller Cooler

Tagged: sandia, impeller, heatsink, cooling, cooler, air bearing

A white paper by Sandia National Laboratories caught the attention of the media last year with big claims for high performance cooling. The researchers had claimed to invent a new type of heatsink based on a impeller design that was allegedly 30% more efficient at heat transfer while being smaller and quieter than traditional air coolers.

Dubbed the Sandia Cooler, the team has come up with an updated prototype that is nearly ready to come to market. Shown off in a recent video, the cooler is a small heatsink based on three relatively simple parts. A stationary disk acts as the base and area that comes into contact with the Integrated Heat Spreader (IHS) of a CPU. Then, a spinning array of curved fins resembling an impeller design is spun up by a small motor mounted in the center of the cooler.

During an industry day, they reportedly signed two license option agreements with two companies to bring the product to market in the areas of solid state lighting (LEDS, et al) and computer hardware cooling, implying that it is getting closer to a final product that it was last year.

Interestingly, the cooler uses an “hydrodynamic air bearing” such that the spinning part of the cooler is spun up to 2,000+ RPM such that the top part separates from the bottom stationary part and rides (they use the analogy of a car hydroplaning) on a very thin layer of air. (Update: as KngRider noted, there is still some friction from the motor spinning the upper part of the cooler, however.) That thin layer of air is what facilitates heat transference from the stationary part to the spinning fins. It does raise questions of efficiency, however. How a layer of air is more efficient than thermal interface material, for example. Reportedly, the air bearing is not an issue that will impact cooling performance but it is a difficult concept to grasp considering TIM and metal-to-metal contact has always been touted as the best cooling situation.

Sandia explains that cool air is drawn into the center of the impeller as heated air is forced outwards through the spinning fins, which reportedly enables efficient heat transfer. In the video, they demonstrate that it is capable of being extremely quiet (nearly silent) despite spinning at an extremely fast rate – the noise in the first part of the video is due to the prototype motor that is not covered. They claim that the final design will use a brush-less motor that will be much quieter.

It’s an intriguing design because of its simplicity and form factor. It is reportedly able to cool more efficiently than some of the best air coolers on the market, which use such techniques as heatpipes that come into direct contact with the CPU IHS, larger fin arrays, and multiple fans. Compared to those coolers, the Sandia prototype is much smaller and simpler in its construction.

The company has further released a white paper (PDF) and has an area of its website dedicated to more information on the Sandia cooler. While I cannot vet the fluid dynamics they detail, it certainly looks good on paper. I’m excited to see this come to market and whether or not it will live up to its promise of more efficient (and quiet!) cooling. It could be an important asset in cooling computer hardware in everything from desktops to server rooms. Also, it might just be the advancement that air coolers have been looking for as far as the next jump in performance – more than simply adding additional heatpipes or fins (and dealing with weight, size, and diminishing returns as a result) can do alone.

I’ll say that I’m skeptically optimistic on this one, but I do hope that it’s the real deal. What do you think of the impeller cooler? Does it appear promising?

The FrioOCK is a universal CPU cooler that supports a variety of socket types from Intel (LGA1366, LGA1155, LGA1156, and LGA775) and AMD (AM3, AM2+, AM2). This heatsink uses a dual-tower design with six copper heatpipes to dissipate heat from the processor. The unit also sports two 130mm fans in a push-pull configuration to wisk heat away from the CPU.

Just Delivered is a new section of PC Perspective where we share some of the goodies that pass through our labs that may or may not see a review, but are pretty cool none the less.

We got a box in from MAINGEAR over the weekend.  It did NOT include a PC.  Instead, we are getting our first experience with the Epic 180 CPU cooler.  

epic1.jpg

What you are looking at is a high end self-contained water cooler that exceeds the size of anything we have previously seen in the PC Perspective labs.  As the name implies, the Epic 180 is based on a 180mm radiator and fan and this likely means the number of chassis that will support it are limited. 

epic2.jpg

In this image, the Epic 180 (left) is compared to the original Corsair H50 cooler (right) with a 120mm fan on the radiator. Wow...

epic3.jpg

We will have a lot more details in upcoming stories but you should expect the Epic 180 to support LGA1155/1156, LGA1366 and of coure, the upcoming LGA2011 Sandy Bridge-E sockets.

MAINGEAR claims that the Epic 180 will offer 20% better performance than other similar coolers with fan speeds at around 1000 RPM, keeping your rig both cool and quiet.  More details very soon!!

Akasa's Helix Widescreen notebook cooler has arrived just in time for summer, bringing not only a cooling breeze to your laptop but also looking relatively stylish at the same time.  The large size does negate the ability of most people to be able to place it on their laps, so the cooler is intended more for high powered gaming laptops that have trouble keeping their cool over extended gaming sessions.  eTechnix preferred it to the Lapchilla they reviewed previously but warn their readers not to expect cooling miracles.

"Akasa are at the forefront of the PC components market and are well known for their 'Superb Design and Engineering'. Currently their products range from CPU coolers and fans to cases and power supplies and several things in between. They are a company who are very aware of its target market and as such tend to produce products that are very popular, like the Akasa Venom for instance."

Tagged: heatsink, xigmatek, cooler

Loki, Gaia and Aegir are all from Nordic mythology but are also now found in PC Cases as well as in Valhalla.  Loki and Gaia can be had for around $30 while the Aegir comes at twice the price and the sizes range as well from the diminutive 330g Loki to the 670g Aegir but all are 159mm tall or less.  Legit Reveiws proclaimed that they are all great values, each with their own traget system.

LR_xigmatek_round_up_010.jpg

"The Aegir is Xigmatek’s high-end offering, and it carries a high end price. Coming in at $59.99 shipped it is not the most expensive cooler we have ever tested but it performed nicely. Coming near the top of the charts throughout most of the testing the Aegir was on par with coolers that cost $20 to $30 more. The fan for the Aegir was nice as well. At 100% speed the fan is quiet. It was hard to pick out the Aegir’s fan from the Scythe case fans I use in the test system..."
