Hey guys, those of you interested in reading this roundup are probably a group of those people, that prefer their enviroment to be as silent as possible or are running a lot of up-to-date hardware that has to be cooled properly. Normal radiators often reach their limit when cooling up-to-date hardware, especially in summer and that’s why people request bigger radiators. When the first “monster-radiators” for up to nine radiators got released, there was a lot of criticism because you couldn’t use all the performance, but it turned out that they become more and more popular. That’s why it’s no surprise that Watercool comes up with the new MO-RA 3 models, of which I want to present two of and test them against their predecessor MO-RA 2. Also competing we will find another popular radiator made by Phobya: the Nova 1080, which doesn’t have to hide when compared to the models by Watercool and can also be expanded with a lot of accessoires, but we’ll get to that later. Let’s start with presenting the candidates: UPDATE : Phobya Xtreme SUPERNOVA 1260 Radiator Phobya strikes back ! This brandnew Supernova Radiator climbs on top of the charts ! The little brother, Phobya 1080 brings a very good performance and has many fans around the world, but this one even beats the Big Mora 3 for 140mm fans ! The good thing is: You can mount 140mm or 200mm/220mm fans and both fangrills are included in the package ! There is a separate Rad Holder available, which gives this Monster a safe stand on your desk or on the floor. Well, the performance is really impressive, because of the 6x G 1/4" Threads, even a 2- or 3 Loop Watercooling System is no problem for this big black thing ! The overall build quality is ok, but hey, Mora 3 Series looks and "feels" better at all, because of their stainless steel grill and german craftmanship. But when you´re in the market for the BEST Radiator available when it comes to the performance, this Phobya Xtreme Supernova 1260 Radiator is the one for you ! Technical data: Size: 460x420x46mm Threads: 6x G 1/4" Fins per centimeter: 5 Screw threads: M3 Weight: around 5000g Price: 180 EUR The Phobya Xtreme Supernova 1260 Radiator earns the GOLD AWARD for it´s awesome performance ! Watercool MO-RA 2 PRO For those of you who didn’t know it already: MO-RA stands for “Monsterradiator” and this model was succeeded by the MO-RA 3 by now. Still I want this radiator to take part in this roundup, as a lot of units of it are around and there are probably a lot of people upgrading from this one who want to know the differences in performance to other radiators of this size. The MO-RA2 is a radiator made out of tubes, which is, as far as I know, a kind of radiator building only used by Watercool and makes it a lot easier to get the air out of the system. Size: 39 x 5,7 x 41.5 cm Threads: 2x G 1/4" Fins per centimeter: 6 Weight: ca. 5000 g Fan size: 9x 120 mm Pressure tested: 2 Bar 4x M4x8 mm allen screws 4x M4x20 mm spacers, steel 4x spacers 1x allen key Price: around 120 € + fan grill around 30 € > This radiator isn’t produced anymore! < Phobya Xtreme NOVA 1080 Phobya continues their popular radiator series with this oversized Phobya Xtreme NOVA 1080. While their smaller models scored well in former reviews, this model doesn’t change that at all. When in factory setting, it can suck up up to nine 120mm fans with the fan grill it comes with. Other grills are also available at extra charge just like with the MO-RA3, offering mounts for 4x180mm or mounting fans on both side of the radiator. Furthermore, stands has also been made available. The user Cartago2202@HWluxx.de has also presented the 4x180mm grill before, I’ll also include a few of his pictures for illustration. But let’s get to the most important part of the Phobya Xtreme NOVA 1080: its performance. It doesn’t have to hide when tested against its competitors. The Nova 1080 performs as well as the MO-RA2 and isn’t too far behind the 120mm version of the newer MO-RA3. When it comes to build quality, you have to lower your sights when comparing, but when you look at the price, that’s around 35€ less than the cheapest MO-RA radiator, you can just ignore the slightly worse paint and the simple fan grill. Overall, the buyer gets a product, that’s very suited for current high end systems with several graphics cards. By the way: the radiator is now available in a new revision that comes with a black fan grill! Technical data: Size: 36 x 5 x 38.5 cm Threads: 2x G 1/4" Fins per centimeter: 5 Screw threads: M3 Weight: around 2745g Price: around 90 EUR + fan grills for 180mm fans or additional 120mm fans The user Cartago2202 has presented the grill for 180mm fans and the fitting radiator stands in the following link (in German): http://www.hardwareluxx.de/communit...180-und-die-passenden-standfuesse-751693.html The Phobya Xtreme NOVA 1080 radiator gets the award for value for money! And the Bronze Award for the third place in performance: MO-RA 3 PRO (Version for up to 18x 120mm fans) Let’s get to the successor of the successful MO-RA2 radiator, that was very popular for several years. The older versions required a grill sold at extra charge to mount fans and stands weren’t available at all. Apart from a lot of other changes, this was also addressed when Watercool released the new MO-RA3 series. But, of course, they’ve also improved the performance. The MO-RA3 is the result of further developments based on the MO-RA2. The performance was improved and a few more features have been introduced. More than 36 m of copper pipes and 3 m² fins are in every single MO-RA3. The coolant flows simultaneously in 80 pipes. The new, high-flow fitting-socket with three G1/4” threads also enables you to use, for example, a reservoir or a fillport directly at the radiator. While a fan grill isn’t necessary anymore, you can still buy one for visual improvements and is available in several designs and colors. The available stands are also available in clear or black. The MO-RA3 is available in several variants, from models for 9/18 120mm fans, versions for 4x180mm fans up to the mega radiator for 9/18 140mm fans. Just as known from the old MO-RA2, the build quality is good an d the performance outstanding. Even high-end-systems can easily be cooled with the MO-RA3. The MO-RA3 comes with everything required to start at once. The scope of delivery includes caps to seal the unused threads, fan screws and of course also spacers to mount the radiator on the case. Using the flexible modular design, the MO-RA3 can be customized according to your wishes. There are several fan grills, fan controllers, stands and external mounts.

As we’res testing the PRO-version right here, we can mount nine of them on each side, so up to 18 fans on one radiator. Up until now, there is only one fan grill available and the radiator only comes in one color: black, while other versions are probably coming soon. The stands for the 120mm version can conviently also be used for this version. Because of the bigger fans and the bigger radiator size we can once again see a better performance. For those of us who can’t have a radiator big enough or who want to have the performance of their dreams, this is the fitting radiator. Before releasing this radiator, the manufacturer asked the users in their forum for voting for several sizes. This was implemented in the final version – a nice option which should be used by other manufacturers in the future – it’s always nice to be part of the development of a product while only being a consumer after all.

Sensor in the reservoir for calibrating Filter by Aquacomputer Gelid Extreme thermal paste Innovatek Protect Ready-to-use ArctiClean To put maximum load at the CPU, Prime95 (small FFTs) was used in the newest version; to measure the temperatures I used the Aquasuite. These temperature measurements were done after no less than 60 minutes in 5 planned intervals of 5 minutes. I also ran Furmark at the same time to load the EVGA GTX480 VGA-cards. The most interesting value in this test was the difference in temperature (Delta T) of room temperature to water temperature of the water exiting the radiator. This value shows the cooling performance of the radiator very well by showing how well the radiator can use the room temperature to cool down the water. The less this difference is, the better the radiator performed. The results should easily be understandable for the interested user, so I’ll only add the values for flowrates and the values at different fan speeds.
