Tagged: thermaltake, msi, CPU Water Block, cooler
Normally a water block presses against the CPU heatspreader, but this one is a bit different. MSI and Thermaltake decided to team up and make a motherboard-specific cooler that pulls heat away from the CPU and the motherboard's VRM MOSFETs. This way, water chills both the CPU and its power delivery, which could be a bottleneck when overclocking.
Note that this is not a closed-loop cooler. It is designed to be embedded in a custom cooling loop, which means that the user (or a small business computer store that maintains their PC) is responsible for routing water and preventing leaks. That said, users who are looking for a high-quality cooler for their power delivery system should expect a little commitment to their build (and a little risk).
Also, since the product is designed for a specific motherboard, the user shouldn't expect to keep it hanging around from build to build. You will almost definitely use it while you have it and leave it when you move on. On the other hand, you shouldn't worry about it covering your RAM or anything -- you can be reasonably assured that it's built for your setup. (That is, unless you buy the wrong motherboard or something... d'oh!)

Tagged: fanless, cooler
We are getting a fair amount of “big heatsink” options for enthusiasts, which is nice. This one is from a Japanese manufacturer, Scythe Co., and it's quite big. It is similar in size and weight to the Noctua D14, but in a four-tower design. Each stack of fins has three heat pipes, twelve fingers total, to deliver the heat up from the plate that rests on your CPU. It measures 13cm x 15.5cm x 15.3cm and weighs 0.9kg.
The product page doesn't seem to declare a fanless operation mode, but FanlessTech mentions that previous models were advertised at, not just abused by enthusiasts to, 65W in passive configurations. It is a pretty large cooler, so that makes sense. I have also seen a few posts where the Noctua D14 can be used fanless for around 65W. You cannot really make an apples-to-apples comparison between the two units though. While the size and weight are similar, the geometry is quite different. For example, the Noctua is really designed to have fans installed between the two towers as well as the ends, blowing air over the fins in a certain direction.
No news about pricing or availability for Europe or North America yet. The company does have an international presence though.

Tagged: hyper 612, heatsink, fanless, cooler master, cooler
The Cooler Master Hyper 612 Ver. 2 CPU cooler is a member of their "Hyper Series", upper-mainstream product lineup. It looks to be one of the (if not the) biggest offerings in that category. Its extreme dimensions are 139mm (5.47") in length by 102mm (4.02") wide, with a height of 160.4mm (6.32"). It has a 120mm fan which basically takes up a whole side and slowly blows air across it. Some sites claim that it can be used fanless with some (but not every) CPU.
Cooler Master is particularly proud of their "Continuous Direct Contact" technology. In other words, the heat pipes are flattened into a contact with the CPU's heatspreader (or die guard for people like Morry). This eliminates a reservoir of heat before the copper pipes can carry it to the aluminum fins and out into the air.
The heatsink is now available, but no pricing information yet (I cannot find it online).

Tagged: noctua, nh-l9a, hsf, cooler, mini-itx, low profile cooler
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.

Tagged: silentmaxx, passive cooling, hsf, cpu cooling, cooler
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.

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?
Introduction, Features, Technical Specifications
Performance CPU coolers have been saturating the market in bunches this year, and Thermaltake added the FrioOCK to the fray to compete against other high-end heatsinks geared toward overclockers and power PC users. We wasted no time installing the FrioOCK in our LGA 1155 teset bench to see how it stacks up against other extreme air-cooled CPU coolers!
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.

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

Tagged: akasa, cooler, helix
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."
