Specifications, Availability and Pricing




The Xigmatek Prime SD1484 consists of 710 grams of aluminum fins, the base plate and the four 8mm diameter heat pipes. The aluminum base allows the four pipes to be exposed with slim strips of aluminum between each pipe comprising the H.D.T surface that Xigmatek is known for. The base of the pipes are exposed copper, but as they make the bends out of the base and travel through forty-six pressed on fins, the pipes are coated in Nickel plating all the way to the tips at the top. The fins arrangement is something I have never seen done from Xigmatek before. Using a 0.5mm fin, they have profiled the edge of each fin so that at the leading edge, there is a taper and the fin is only 0.3mm thick at this edge. On top of this, they use shaping on each fin to allow for cavitations in the design to aid in disturbing the airflow for more efficient cooling performance. Let me just say this, a picture is worth a thousand words and I have an image waiting that shows all of this for you.


There is one 140mm A1425L12PS fan shipped inside, but another can be ordered for a dual fan configuration as there is supplied fan hardware to do so in the box. This fan is specified to run at 1200 RPM maximum with twelve volts supplied to the fan. At this speed the fan is capable of delivering just more than 90 CFM while only registering in with 18 dB noise levels. The static pressure of these fans isn't all that great with a 1.08mm H2O rating, and using the PWM feature of the 4-pin connector, that rating is also a maximum value. With my cooler, Xigmatek also sent a second fan matching the one shipped in the SD1484 package, so I will do a bit of push/pull fan testing as well. The fan gets mounted to the cooler with rubber straps much like those of the NZXT Havik 140, and as I mentioned, there are four straps included, so I am all ready to go with both fans and the Prime.


The Prime SD1484 has released enough for a few sites to get samples, but expect a couple of weeks for this to actually fill the shelves at your favorite retailer or online shops. I know it's a bit of a downer to have to wait to have your own look at the Prime SD1484, but there is a silver lining. From what I can gather, Xigmatek is placing a MSRP of $55 US Dollars on the Prime! Considering with the economy the way it has been, I had to raise that "magic pricing" from our older assessment of $50 and moved it closer to the $60-65 range; the Xigmatek is fairly priced with these tougher times on our wallets. Is the wait for the "legend" that is the Prime SD1484 worth it? See for yourself over the next few pages as we dissect the Prime and see what it offers!
