Introduction

IntroductionThere is a good chance that you have never heard of Auras Technologies Co., LTD but there is a bigger chance that you have seen their products before. With partners such as Dell, Apple, NVIDIA and several others, Auras has stayed busy since the company was formed in 1998. With success in the OEM/ODM market Auras is now ready to move into the public spotlight with their name featured right on retail packages. Auras' headquarters is situated in Taipei, and with three factories in China it is clear that the company is off to a great start. Today we will be looking at the Auras TwinW, also known as the SMF660. This copper base, aluminum fin cooler places a single fan in the middle of two moderately sized cooling fin areas that utilize the push/pull effect of the fan. Let's dive in and see what the TwinW is all about.

Specifications, Availability and Pricing

Specifications, Availability and Pricing
The Auras website takes the minimalist approach when displaying the specifications of the TwinW, but all of the relevant information is listed. The TwinW is an Intel Socket 775 only cooler so AMD motherboards need not apply.The mounting mechanism is similar to the stock Intel coolers, using the four push pin tabs that go through the motherboard without needing to remove the board. If you are like me and many long time enthusiasts, this is a big selling point when mounting heatsinks for typical applications where extreme cooling is not needed. To date I have not been able to find the TwinW for sale in the US, or anywhere else for that matter. Since the product was just announced in January I am sure it will start showing up on e-tail sites before too long.

Packaging

The Package
The grey and black package give the TwinW a sinister look that is appealing. Not a lot of information here so we will move on.
From the side we see the specification and application list.
On the back we find the UPC listing and learn that the TwinW has been approved by the FCC and CE already, this clears the way for the product to be sold in the US and Canada.
The other side rounds out the feature list, this time with images that give the consumer a simple walk thru of what they can expect from the cooler.

The Cooler

The Cooler
On the front we can see that the TwinW places heatpipes close to the middle of the cooling fins. On the other side the pipes are spaced further apart.
The fan is placed in the middle of the cooling fins allowing the TwinW to utilize the push and pull flow of the fan to cool the processor.
From this angle we see the heatpipes spaced further apart allowing the fins to work more effectively.
The Auras TwinW uses a 4-pin PWM power cable that allows the motherboard BIOS to control the fan by varying the voltage going to the fan.
From the top we get a better view of the heatpipe arrangement.
The contact area is just shy of a mirror finish. This 2.5mm copper base has a better finish then most of the coolers we have seen in recent weeks.

Accessories and Documentation

Accessories and Documentation
The accessory list is pretty slim for the TwinW, but what else can you really ask for. Auras has included everything you need to apply the cooler to an Intel motherboard including premium thermal paste.
The manual for the TwinW doesn't need to cover much since it is for Intel motherboards only. It does cover all of the basics and we were satisfied with that.
When installing the heatsink to our TECC setup I did find that the push pins get caught in the fins as you can see here. Installing the heatsink is still straight forward but you will need to make sure the pins are locked into place.

Testing Results

Test ResultsTweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.
At idle and load the Auras TwinW is comparable to the stock Intel heatsink. I was expecting better performance from the cooler but this is not the first time I have been disappointed with the performance of a heatsink this month.
In our Sound Pressure Level Test we see that the cooler does outperform the Intel Stock Cooler. The full 12-volt load is comparable to many of our other tested heatsinks.

Final Thoughts

Final ThoughtsAuras has a promising future in the retail market, but the TwinW is not going to be the break out product they need to make a lasting impression. From the website it looks as if the company is the original manufacturer of the Rosewill Z5 that we still call our under 40 US Dollar performance leader (for coolers that we have tested, that is), so I am positive that the company will be able to manufacture coolers that are capable of leading their market. The TwinW isn't ready for high-end processors and the cooling performance is only comparable to Intel Retail coolers, but many people purchase OEM or tray processors without the retail heatsink. If the price is right then the TwinW may be a good stock replacement if you can find one. The mounting system is a little awkward with the way it lines up with the cooling fins, but at least you do not have to remove the motherboard for installation.
