I got this absolutely massive package from Aquatuning a couple of weeks ago, and this was one of the first things to catch my way. I suppose I have always been interested in things that very few people can fit inside a case, and this product is one of them. To be fair to both Aquatuning and Phobya, their Xtreme series of radiators are marketed more as external radiators and this is one of the smallest in that series- coming in at a “mere” 480 or 560 mm of fan space allocation. That’s right, this can serve as either a quad 120 or quad 140 mm radiator or even a hybrid of the two. It is also a square radiator and that brings with it some unique advantages and challenges. Thanks to Eddy from Aquatuning, we can now take a look at this for ourselves.

Let’s begin by taking a look at the specs from the product page on the Aquatuning US website:

Technical details
Case: Steel
Color: black
Connector: 7 x G1/4
Cooling channels: Brass
Dimensions (L x B x H): 280 x 322 x 49mm
Fan mounting thread: M3
Fan size: 120mm, 140mm
Fins per inch: 12
Manufacturer: Phobya
Material lamellae: Copper
Number of fans: 4
Pressure tested: 2 Bar
Thickness: M – 45mm

Before you say anything, no the case is actually not all steel- just the fan grills, which definitely don’t come in contact with any coolant under normal operation. The core itself is made of copper and brass, as with just about any decent radiator (I am looking at you here, Thermaltake!). Stainless steel by itself is mostly fine with these metals too, but it’s a moot point now. The radiator comes in only black color options which is a bit of a shame considering many would like to have this outside a case and color options would be nice here. The dimensions are of either extreme importance- if you are looking to fit this inside a case- or not at all- if you are going externally- and so please do be aware of this. Considering this is a square style radiator, the length and breadth dimensions are different compared to more typical radiators that extend in a single direction with an increase in the number of fans supported. Speaking of which, this radiator has an interesting trick up its sleeve regarding fan compatibility which we will get to visually in the next page. We will also see which the radiator “thickness” is less than what is seen in the dimensions tab. For those who use air leak tests, please stick to no more than 0.5 bar (~7 PSI) of overpressure in the loop as a lot of radiator tubes are only rated for a maximum pressure of 2-3 bars.

On to the next page now for a better look at the radiator!
