Testing Results & Conclusion
For comparison and evaluation, we use data collected from prior, standardized tests performed on our six-core Core i7-5930k platform operating at 4.20GHz and vCore of 1.20V. We will be looking at the Raijintek Orcus 360 and how it compares to other, large 360 AIOs; the Corsair H150i Pro and NXZT Kraken X72.
The thermal load testing of these three large 360mm coolers results in the Orcus 360 falling a little behind the Corsair H150i Pro, while the NZXT Kraken X72 turns in the lowest CPU core temperatures. In an interesting twist, the Orcus 360 provides the best cooling results for our motherboard power-delivery system.
Radiator fan speeds are often an indication of cooling performance, and it would seem that that trend might very well come into play here, as the Raijintek Orcus 360 posts the slowest rotational fan speeds of the group. It should be noted, though, that faster fans often produce higher relative noise levels.
Again, our charts fall right into the expected places, with the Orcus 360 offering whisper-quiet noise levels at 100% fan RPM. It would seem that Raijintek wanted to emphasize quiet running over brute-force cooling methods on this cooler.
With load temps within range of the other coolers, and excellent relative noise levels at both full and half speeds, the Orcus 360 is the only cooler of the group to post a positive chart for acoustic efficiency.
The Raijintek Orcus 360 is also the lowest-price cooler of the trio, at $150, which almost seems like a bargain, considering it is the only unit of the group to offer unified RGB lighting for both the CPU block and fans.
Conclusion
RGB-lighting enthusiasts will be drawn to the Raijintek Orcus 360 for the depth and filling glow provided by the RGB fan rings. In darker settings, the color from the circular LED arrays is vibrant and pronounced.
For the first time liquid-cooler, the flow-meter "blade" in the center of the CPU block provides a welcome indication that coolant is running through the system as it should be, although on a few occasions the blade rotation stalled, then slowly started again. There was nothing physically wrong with the cooler or the pump, as recorded temperatures still showed our CPU being cooled, just as it should be. Most likely, this was just the impeller encountering a bit of turbulence within the block chamber, causing rotation to stall. Still, that might be alarming to those not expecting it.
On the whole, we are keen on the Orcus 360. If you're in the market for a big-bore CPU cooler for mainstream CPUs, packing more than its fair share of RGB lighting, you'll want to give this AIO cooler a fair spin.
