Xigmatek Tower Cooler Round Up


Xigmatek Tower Cooler Round Up

Xigmatek has been around for many years. They started out with CPU coolers and now have a wide range of products from coolers for just about everything to cases, power supplies, and their own line of thermal paste. Today we are looking at 3 of their CPU coolers, the Loki, Gaia, and Aegir. Xigmatek pulls their product names from mythology. Loki is from Norse mythology, mostly known for being a shape shifting trouble maker. Gaia is from Greek mythology, also known as Mother Earth. Aegir is again from Norse mythology is the god of the sea.

Xigmatek Tower Cooler Round Up Coolers

When it comes to Xigmatek coolers there are couple things that have proven to be a given for their coolers. First they are almost always H.D.T. or Heatpipe Direct Touch coolers, and their fans are rubber isolator mounted. This tends to make their coolers lighter and quieter than the competition.

Xigmatek Loki Tower Cooler

The Loki is the smallest of the group we are looking at today. Being only 134mm tall and sporting a 92mm fan, it will be the smallest cooler we have ever run on our Intel Core i7 test bench aside from the stock Intel HSF. Coming in at 330g without the fan the Loki is also very close to the lightest cooler we have tested, too. It is going to be very interesting to see how the Loki can handle the Intel Core i7-930 processor at even a mild overclock due to its small size. The Loki is available for just $22.99, so it's clearly aimed at budget friendly consumers or those that want a small HSF.

Xigmatek Gaia Tower Cooler

The Gaia is in the middle of the pack. Coming in a 159mm and sporting a 120mm fan the Gaia is more like coolers we have been seeing as of late. The main difference is the overall weight. Coming in at a scant 460g without the fan the Gaia is light compared to coolers of the same dimensions. Also coming in at the $29.99 mark the Gaia carries an entry level budget price, but with the larger size and 120mm fan the performance should be better than the Loki.

Xigmatek Aegir Tower Cooler

Then we have the $60 Xigmatek Aegir. The Aegir is the biggest of the bunch. It is 159mm tall like the Gaia, but the Aegir has more heatpipes and also has some of the heatpipes doubled up on top of each other. The Aegir has a double layer of heatpipes on the center two heatpipes. Coming in at 670g the Aegir is the heaviest of the group and also the only one of the group to have an LED fan. Also, out of the norm is that Xigmatek went with white LEDs for the Aegir's fan. Let's take a closer look at these coolers and then move on to testing!

Looking at the Loki SD963


Xigmatek Loki Tower Cooler

The Loki is the smallest of the coolers we are looking at today. Coming in at 134mm tall it is also the smallest cooler we have put on our Core i7 test system to date, other than the stock Intel HSF. The Loki comes with a single 92mm fan that pushes 52 CFM, spinning 1200 to 2800 RPM at 20 to 28 dBA. The Loki can be set up for push pull by adding another 92mm fan. Xigmatek does include the mounts for a second fan.

    Looking at the Gaia SD1283


    Xigmatek Gaia Tower Cooler

    The Gaia is in the middle of the pack today. Coming in at 159mm tall it is a tall cooler; most cases can accommodate coolers this tall, but it always good to check. The Gaia comes with a single 120mm fan and can accommodate two 120mm fans. The fan that comes with the Gaia is a PWM 120mm fan running 800-1500 RPM at 16-24dBA and pushing 56.3 CFM.

    Looking at the Aegir SD128264


    Xigmatek Aegir Tower Cooler

    The Aegir is the biggest of the group. It is the same height as the Gaia, 159mm, but it is 10mm wider and deeper than the Gaia. The Aegir also comes with a 120mm fan and can be setup for two in a push/pull configuration. The included 120mm is a PWM fan running 1000-2000 RPM at 20dBA and pushing 89.45 CFM. The fan is also an LED fan, but unlike most coolers that have a blue or red LED the Aegir comes with a white LED fan.

    Features of the Aegir SD128264

    Specifications of the Aegir

  • Heat-pipe
  • Fan
  • Weight 670g (w/o fan)
  • Thermal Resistance: 0.13 *c/W
  • Xigmatek Aegir Tower Cooler

    The fin profile of the Aegir is symmetrical and, like the Gaia, the channels for the fan mounts are in the corners on the sides.

    Xigmatek Aegir Tower Cooler

    The Aegir has an interesting heatpipe arrangement. There are 6 heatpipes in all, but 2 of those are sitting on top of two other heatpipes. There are two 6mm pipes to the outer edges and two 8mm heatpipes in the center.

    Xigmatek Aegir Tower Cooler

    On top of the two center 8mm heatpipes sits another pair of 6mm heatpipes.

    Xigmatek Aegir Tower Cooler

    Xigmatek provides everything that is needed to mount the Aegir to any of the Intel LGA sockets and AMD K8, AM2, AM3 sockets. Also included are enough fan mounts to mount two fans, and thermal paste.

    Xigmatek Aegir Tower Cooler

    The only thing I could see that could be of concern is that the mounting bracket on the motherboard got very close to the heatsink around the CPU socket. So if you have large heatsinks that are close to the socket you could have issues.

    Xigmatek Aegir Tower Cooler

    Here we have the Aegir installed in the test system and running. The LED fan was enough to light the inside of the case nicely.

    Temperature Testing Results


    Xigmatek Tower Cooler Round Up

    With the system running at stock settings the Loki and Gaia seem closely matched in spite of their size difference. The Gaia, however, was better and ran quieter than the Loki due to the 120mm fan on the Gaia. The Loki comes in at 61*C, 18.5 degrees better than the stock Intel HSF. The Gaia comes in at 59.75*C, 19.75 degrees better than the stock Intel HSF. The Aegir did well coming in at 56.25*C, 23.25 degrees better than the stock Intel HSF and only 2.25 degrees behind the top cooler, the Prolimatech Super Mega.

    Xigmatek Tower Cooler Round Up

    Pushing the system up with a mild overclock to 3.5GHz the gap between the Loki and Gaia increased. The Loki comes in at 69.25*C, close to the performance we got with the Corsair H60 and CoolIT Vantage ALC water cooling kits in their “quiet” modes. The Gaia comes in at 66.75*C, coming on par with the recently tested Thermolab Trinity on low. The Aegir came in third place overall at 61*C, on par with the Noctua NH-C14 low profile cooler.

    Xigmatek Tower Cooler Round Up

    With the Loki pushing 70*C at 3.5GHz I didn’t think it would handle 4.0GHz. I did test the Gaia and Aegir. The Gaia comes in at 77*C in between two water coolers, the Antec Kuhler H2O 920 in “silent” mode and the CoolIT Vantage ALC on Extreme. The Gaia was slightly louder than the Antec, but quieter than the CoolIT. The Aegir is still at the top of the list coming in at 70.25*C beating the Corsair H70, and only slightly behind the Prolimatek Super Mega; and the Aegir did it quieter.

    Final Thoughts and Conclusion


    Xigmatek Loki Tower Cooler

    Overall, I was very happy with all the coolers we looked at today. I was surprised at how well the Loki did for its size. The Loki could be an option for those will small cases that need a solid cooler but height restrictions prevent tall coolers. With the Loki’s fan being rated at under 20-28dBA it may not be a fan that is silent or that HTPC builders will want, but it is not something that any other user will complain about. With the Loki coming at $22.99 shipped it would be a very nice budget upgrade for any system still using the stock cooler that came with their CPU.

    Xigmatek Loki Tower Cooler

    The Xigmatek Gaia is a nice all round cooler. Like the Loki it comes in under the $30 mark, but the Gaia performed better than some coolers that are 2 and 3 times its cost. With the Gaia being larger than the Loki it has more cooling fin surface, but also the ability to use 120mm fans. The fan that come with the Gaia is a nice fan and you have the option and ability to add a second fan if you choose. The performance may go up slightly, but the noise will, too. With the Gaia’s performance out of the box and its $29.99 shipped price tag the Gaia is a very reasonable choice for anyone with a midtower and up size case that wants to upgrade from stock cooling. The most consistent competition for the Gaia throughout testing was the Corsair A50, also an HDT cooler that can be found for around the $30-40 price range. Though, the 120mm cooling fan for the Gaia operates much quieter than the one used on the Corsair A50.

    Xigmatek Loki Tower Cooler

    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. Also, the fan is out of the norm since it is a white LED fan and not the normal red or blue. The light coming off the white LEDs will light up the desktop if you have a side panel window. It may not be an issue for some, but users like me that have their desk not far from where they sleep the extra light could be an issue. Since the Aegir uses standard 120mm fans they can easily be replaced if the light is an issue.

    Overall, installing the each of the coolers was a snap. The instructions are clear and easy to follow. The only real issue, well more of a concern, that I found was with the Aegir’s mounting system gets very close to the heatinks around the socket. If your board has large heatsinks around the socket then you may have a clearance issue.

    Legit Reviews Value Award

    Xigmatek has sent us some solid performing coolers that cover a wide range of users from entry level to middle of the road to high end. Overall I am giving the Loki, Gaia and Aegir our value award for being solid performing coolers that are super easy on the wallet.

    Legit Bottom Line: Xigmatek Loki, Gaia, and Aegir are solid performing coolers at reasonable prices. The Loki and Gaia are at the top of the short list for budget upgrades, and if you want to pony up a little more coin you can have the Aegir and its high end performance.
