Many high end reference video cards come with blower motors in them that are loud, but push a good amount of air at high RPM. Most video cards come standard with fan impellers that operate much more quietly in comparison. Low end cards may be passively cooled by a larger than normal heat sink and adding a fan to this would give it better cooling. Consumers have a few options to combat heat and noise, such as better case cooling, different video card heat sinks, or fans/blower motors attached to the expansion slots to help ventilate the area. TITAN has provided for review a dual-fan expansion slot device called the Dual X Holder TTC-SC07TZ(RB) that offers fan speed control to help cool the motherboard and video card!


Closer Look:

The front of the box has a picture of what to expect with the product, except that the cables have been removed from the image. The fans can be replaced with any size fan ranging from 60 to 90mm and up to 25mm depth. The fan farthest from the bracket can be mounted facing the side of the device at a 90° angle. The fans are connected to a fan controller that is adjustable on the expansion slot to fine tune the system performance between noise and heat. The back of the box has the features that are shown in pictures with descriptions underneath in English. To the right, the features are translated into eight more languages. The bottom right has a picture for the included accessories and device specifications. The bottom left has several recycling images and the words "Save the Earth Save the Trees." The top and bottom continue on with the box styling, with the company contact information on the bottom side.











Everything comes out of the box in a bubble wrap bag. The accessories are arranged in three baggies that contain two L-brackets for 90° mounting with two extra screws/nuts, longer screws for deeper fans, and two expansion slot screws. A manual is included and shows how to install the device normally and also how to mount the second fan differently.



Time to get a closer look at the device itself!

Closer Look:

With the device out in the open, we get a glimpse at the cabling situation. The design isn't as elegant as the box made it out to look. The fan cables are sleeved up until they join at a Y-splitter, then the cables aren't sleeved. The fan cables had to be sleeved since they aren't joined together like the rest of the wiring, personally I would have preferred to see all the wiring sleeved. The impeller blades have been flipped over, most fans blow air towards their base, whereas these blow away. This device is designed so that all of the screws are tool free and they can be removed with the black nuts on the other side. The two fans attach to a splitter and run into a black box that controls the fans speed. But, only one fan will report RPM since the splitter only gives the appropriate wire to one fan, both fans cannot send a signal when they are joined together. The unit is powered by a fan header and Titan suggests using one off of the motherboard, although users can also use a Molex-Fan header adapter, which is unfortunately not included.














The fan controller adjusts the speed significantly, but even at full blast I cannot hear the fans over the rest of the system noise. The device can hold the second fan at a 90° angle to the first fan, which could help cool the motherboard or shorter passively cooled video cards. The best uses for this product would be on a passive heat sink, where it could help cool motherboard components, cool the back of a card, or installed in a multiple card system for drastic changes.



The screw nuts are textured and have two wings to help make them easy to spin off without tools. The screws resist spinning because they have a flat cubic region, between the head and threads, that sits against the slots in the Dual X Holder frames. The underside of the nuts are textured too and grab the frames to avoid backing off much better than a smooth surface would.

To test this device, I used it in the stock configuration so that the second fan could reach the blower motor on the XFX Radeon HD 6970. Testing methodology is the same used to find temperatures in video card reviews. The temperature was monitored for 20 minutes during the idle durations and 15 minutes during the load durations. The testing was done twice, once at stock, and again with the card overclocked to help determine any differences. The testing was then repeated again with the Titan Dual X Holder.


Testing Setup:





The temperatures were really close at stock. The blower motor may have operated slighty slower with the Dual X Holder, but the video card fan profile is targeted to operate at these temperatures. Overclocked results showed 2°C less on both. This is not a situation where I would use this device. It would serve better with a passive heat sink, a system containing multiple cards, or to cool the back of a card off. There are precautions that need to be taken when doing this however, since the device doesn't sit straight when installed, it actually sags. The frames could ground out on the back of a video card or an impeller could get caught. There is definitely potential in the right circumstances, but in this case the chance was minor.


The Titan TTC-SC07TZ(RB) worked perfectly but has a couple of flaws. The fans operated perfectly, the fan holder/frame setup worked fine, and the tool-less nature was nice. But, it would have been desirable to see thumb screws for the expansion slot versus standard Phillips-head screws to finish the idea off. The Dual X Holder has great potential in the right systems. But with a reference Radeon HD 6970 and a powerful blower motor, the performance was just about the same, only having a slight decrease in temperatures while overclocked. The Holder also sagged when installed in the test rig, rather than sitting parallel to the video card.

Although it didn't perform well in this instance, I could see it being a great upgrade for consumers with passive heat sinks. It could also do well pushing air between multiple cards, where cramped spacing can suffocate parts and make them run hotter. It also should provide some cooling to the motherboard. Cooling the back of a hotter high performance card is another possiblity, with some work of course to keep it from sagging and/or shorting to the back of the card. Overall it is a decent product, but it does have room to grow.
