As in every market, there are trends. Heatsink manufacturers offer variations of designs seen on other heatsinks - some performing better and some worse. Not all heatsinks are designed with the same use in mind – some are low profile, some are silent, even inexpensive, and some aim to cool the best no matter how big or bulky! The behemoth this review focuses on – the Titan Fenrir – sets its sights for high performance cooling. Fenrir is a wolf in Norse mythology that is said to kill the lead god Odin during Ragnarok. This cooler is definitely geared to put up some competition, but we’ll see how well it holds up to the name!

Titan was founded in 1989 Taiwan originally as Sogic Computer Co. The name change occurred in 1992; Titan currently employs approximately 1200 people at its two factories in China. The company aims to provide the best cooling solutions to its customers, looking to become the best computer cooling solutions provider.


Closer Look:

The front of the box is decorated with a menacing face hovering over the name Fenrir in bold red, model number TTC-NK65TZ (RB), with Core i7, Core 2, and AMD X4 badges to the right. Underneath, it proudly proclaims that it can handle quad cores. The clamshell packaging is fairly sturdy, and the detailed inserts are good looking. The bottom has six pictures with the general features of this heatsink; 17dBA operation, 160W thermal load, universal socket support, PWM function, 8mm heat pipes, and 12cm fan. The rear side has pictures that focus on different aspects of the heatsink, such as the heatpipe direct touch, U-shaped heatpipe design, and Fenrir totem. The features section reiterates the main points with a little more detail, and is also repeated underneath in eight different languages.







The right side goes in depth about the fan specifications; 120x120x25mm, 12V, 800-2200 RPM +/- 10%, 33.2 ~ 78.41 CFM, 0.02~0.11 Inch H20 static pressure, <17.2~39dBA, Z-axis bearing, with 60,000 hour lifetime. Continuing on is a guide for CPU support, which lists in detail the CPUs that are definitely supported by this heatsink. The other side shows the included accessories – an adapter to convert the four-pin PWM fan into a three-pin connection, allowing the fan to operate at 1300 RPM, and Royal Grease thermal paste with thermal resistance of 0.032*C/W.



The top of the heatsink is clearly visible through the clamshell packing, with the Fenrir totem adorning the top fin. The sides are all angled and the fins are all stamped with the Titan logo and designs on the sides. The rear has the Titan logo, and company website address for more information.



After cutting the sides off of the packaging, the heatsink is revealed, along with a small box and foldout guide. With the heatsink removed, the fan is seen protected by another fitted plastic mold.



Once the molding is removed, the fan is easily taken out. The fan is stamped Titan TFD-12025H12ZP 12V 0.32A, with the reverse side being fitted with a sticker of the Titan logo, 12V specification, and bordered with a sunny theme. The blades are painted chrome, and the plastic casing is painted a dark gunmetal color. The sleeves are highly flexible, and a tag states that it is RoHS compliant.



With the fan and packaging out of the way, the small cardboard box and foldable installation manual are easily accessed. The guide gives installation instructions the sockets in nine languages, and folds into a very small sheet.



Inside the small white cardboard box are the mounting plates and bracket; also included are washers and standoffs for Sockets LGA 1366, AM2, 939, and LGA 775. The i7 kit is stand alone, while the AMD and Intel LGA 775 share a double sided and insulated mounting plate. Royal Grease thermal paste, fan mount wires, and four-pin PWM to three-pin adapter round off this kit, allowing for most users to be ready out of the box. The completed i7 LGA 1366 mounting hardware consists of the grooved mounting plate, which increases strength and helps keep it from flexing, i7-only bracket, and four thumb fasteners.



The insulated mounting plate's AMD side has three prongs on each side, and is tacked in two spots per side onto the Intel plate, which is also insulated. The insulation is simple black plastic, which is held in place thanks to an adhesive. Each branch has a channel running its length to reinforce the plates, helping to maximize the material's strength. The included thermal paste from Titan named Royal Grease appears to contain around a tenth of a CC of paste, hopefully enough for an application or two, although the cap is flimsy.



With everything unpackaged, let's get a closer look at the Fenrir heatsink!

Closer Look:

Looking at the Fenrir from the front reveals some bent fins and the simple base with four large heatpipes running through, and grooves for the mounting bracket. The clearance from the lowest fin to the top of the base looks to be high enough to clear any motherboard heatsink or capacitor, while being short enough to fit into many computer cases. The side view shows the bent fins more, which are slid into place, where some companies solder theirs to the heatpipes. The pipes are angled away from each other as they rise from the base, spreading them out better into the fins for better dissipation.








The top fin shows off the Fenrir name and totem, along with stamped Titan company logo. The four heatpipes also poke through. Rotating around shows that all of the fins, including the bottom, are stamped the same as the very top. The fins are fairly reflective.



A sticker that must be removed prior to installation protects the bottom from dust, dirt, and scratches. The base has machining marks left behind, and has space between the copper heat pipes and aluminum block. The block is relatively flat, but lapping would help greatly, as should filling the central crevasses with the thermal paste.



The fan installation is fairly simple, looping the hooked ends into the fan's screw holes, and then sliding each wire into the grooves of the fins, on the side that is flatter than the opposing side. Air is likely to escape through the arched opening, so customizing something to fill the void on each side may help increase the Fenrir’s overall performance by forcing all of the airflow through the fins. The clips should also make mounting a larger 38mm fan easy.


With the Fenrir well examined, it's time to take a look at the technical specifications before checking to see how it does under the volley of tests!

Testing for the Titan Fenrir is performed twice, once at stock and again overclocked, with the results of each setup checked at idle after thirty minutes in Vista, and again after thirty minutes of loading the processor with Prime95. The overclocked speed is 3.33GHz (166x20), and the CPU is set to 1.25V. The averages of the four cores’ temperatures are reported in Celsius using the program Real Temp 3.00. All testing is done inside of a computer case to give realistic temperatures, and all settings should be easily achievable by anyone. Ambient is kept at approximately 20 Celsius. Time to see which coolers can handle the i7’s heat output!

Comparison Heatsinks:







At stock, the Titan Fenrir pulled in the lowest idle temperature, while at load trailed the Noctua by a mere three degrees. Overclocked had the aftermarket coolers tie, while at load the Fenrir took the lead by one degree. The Fenrir performed very similarly to the Noctua heatsink, and could easily allow for a higher overclock, while the Gelid and stock heatsinks are pushing it.


The Titan Fenrir was very well packed, and had all the necessary gear to get an easy start to assembly. Assembling the heatsink and attaching it to the LGA 1366 motherboard was quite simple and fairly straightforward, especially thanks to the manual. Installation should also be really easy on most other motherboards thanks to the brackets' design. The Fenrir totem looks cool, and the fins are shapely; the large heatpipes also stand out better than the regular sized ones.

The only main downfall is that the fin design allows a large amount of air to escape through the fins, hurting cooling performance. The bent fins are a nuisance, but easy to unbend.

The included thermal paste is adequate to get a start, and for the price this is a great heatsink that can be tweaked for even better performance!
