Specifications, Availability and Pricing





The first chart that Larkooler provides deals with the pump and reservoir combination unit, as well as the Universal CPU block. The pump and reservoir are fit into an area that is 136mm long, 67mm wide, and stands only 75mm tall without the fittings. Provided throughout the kit are six 3/8" OD barbed fittings with G1/4 threads. The pump also offers two removable caps for bleeding and filling the loop. This pump will run at speeds of 3600 to 5700 RPM, delivering a maximum of 480 L/h of flow. This pump also offers 400CM of lift height of the provided fluid. The connected reservoir will house 250mL of coolant, and there is also a variable speed dial for the pump. There is also a white LED installed into the reservoir.


As for the CPU block: it is made of 330 grams of pure copper that has then been Nickel plated. It also offers G1/4 threaded fittings that are preinstalled, and it is 60mm long, 54mm wide, and sits only 14mm off the IHS. This block does not come apart in any manner, but on the inside there are many tiny skived fins cut into the base to remove the heat from the copper base, and send it on to the coolant to be removed.


The second section of their charts covers everything else about the kit. Starting off with the radiator: it measures 302 mm in length without fittings, is 124mm wide, and is 35mm thick without the fans; this isn't a typical radiator. It uses copper tubes, brass headers, and aluminum fins. However, the fins here are much like what SilverStone was first to show us; they are more like the fins of a tower air cooler than the V-shaped fins of the usual suspects. The provided fans have a maximum rotation of 1800 RPM, and will deliver up to 62.7CFM each. These fans also have a 50,000 hour run time expectation, and they are rated at 31.1 dB(A).


As we move down the chart, there is also some information on the provided thermal compound: the TC1. They supply us with 5 grams of it, allowing for a few applications to get the mounting just right. This paste offers a 3.0W/mK conductivity level, will operate to this level in temperatures from -40 degrees to 150 degrees, and should stay usable for two years before becoming less effective. While that is all good for the customer, to level the playing field, as always, we will be using the MX-2 that every other cooler has used.


The last bit of information on the charts is about the coolant, and there is obviously a choice between the blue and the green coolant; we have received the blue coolant for our SkyWater 330. You get one 500 mL bottle of the coolant, and it will cool with ambient temperatures of -5 degrees before freezing. Also, note that right about the time you would need to replace the thermal paste, they also show that the coolant is due for a flush and refill.


As for the pricing and availability: the Larkooler SkyWater 330 can be found at quite a few locations, and is ready to ship as soon as you make payment. As for the pricing, it may vary a little bit from place to place, but considering the fact that this is priced just slightly more than what most sealed, dual radiator AIOS are releasing at, Larkooler may very well be onto something here. At an MSRP of roughly $130.00 USD; as it sits on paper, the SkyWater 330 seems very on point in the pricing aspect, and provides the ability to add components that the sealed AIOs will not provide for. At this point, I don't see where Larkooler has gone wrong. This is quite the kit for the price.
