Specifications, Availability and Pricing
Breaking this information down a bit for you, we will jump right into the radiators. It is mostly made of a brass construction except for the copper fins of this 2-pass radiator. Encompassing the pump and the reservoir on the opposite end, the MCR220 measures 128mm wide, 325mm from end to end, and is 72mm thick without the fittings in the G1/4 threads. The MCR320 is the same width and thickness as the 220, but the length is increased to 445mm for the 320. The fans come attached to the radiator, but if you should need to change out the hardware, they are mounted with M3.5 thread screws. Without any water in them, the MCR220 and MCR320 weight in at 1079 grams and 1242 grams respectively. As shipped from Swiftech, the radiators are painted in a flat black acrylic paint finish to seal the brass and copper from oxidation, as well as making it much more attractive to look at.
Moving to the next chart we cover the MCP35X pump that is attached to the bottom of the MCRX20 radiators. This DC electric pump is a spherical brushless solution. While the nominal voltage is listed at 12V DC, the pump will operate between 9V and 13.4V DC, so there is some play to be had with the flow rates and pressure of the pump. The following specifications are assuming the pump is receiving 12V DC. The MCP35X will draw 18 watts of power and 1.5 amps worth of current. With this small amount of power, Swiftech is able to deliver 14.7 feet of head pressure and 4.75 GPM of flow at 22 PSI. To power the pump, you are given a 4-pin Molex connection, and to change the voltage supplied to it, there is a 4-pin fan connection with a RPM and Sense wire. Last things to note about the MCP35X are the G1/4 threads on it and the 50,000 hours of expected life.
To rid the reservoir, radiator, and pump combination, Swiftech has included a pair of RDM1225S fans. From doing a bit of research, this is a fan that Swiftech has gone to on many previous occasions. These fans will operate with voltages from 6V to 13.8 V DC. Since the kit includes 5V adapters for the fans, and I tested them, the fans will run with less voltage. At 12V the fans draw 0.23 amps of current, which is very little if you are thinking of using a fan controller. With an RPM of 2000 the RDM1225S will deliver 3.5mm H2O of static pressure and 76.9 CFM of air flow. These sleeve bearing fans will deliver 39 dBA of noise level and get connected with 3-pin connectors with a tach output. As mentioned there are a few extras here too. You get a pair of 7V fan adapters with the pair of 5V ones and both fans are attached to the radiator from Swiftech and have bulls eye fan grills applied to keep your fingers out of the fans.
The pricing of these kits is reasonable in my opinion. I have spent near $400 a few times building a triple radiator loop with all individual parts and then assembling it all. Along that road are many routing decisions to be made from component to component, which parts work best together, and then waiting for three separate orders to arrive so you can assemble it all. Swiftech is offering the H20-220 Edge HD kit for $229.95, and the H20-320 Edge HD kit for $269.95 buying directly from their store. To me, for the results you are about to see, and the simplicity in the way this is installed and utilized, the HD Edge kits are definitely a step above the previous solution, and I already liked that kit at a similar price point! For those of you thinking I forgot about the blocks, well I have to save something, and it is much better explained with images, and is about to be showcased very soon.
