onesmartfuture said:How does it compare with the Corsair H150i Elite Capellix AIO (360mm)? I'm surprised you never had them in your test rig, Corsair being the most popular AIO manufacturer.If I remember correctly, Corsair uses Asetek designed coolers. This means if you test one, you have tested them all. Fans optimized for high static pressure. There are lots of great high static pressure optimized fans out there and lots of different preferences. It’s like asking a car forums their favorite motor oil, you will get a lot of different responses... Yes it’s Rev 2. I recognized it when watching Gamer’s Nexus disassemble video. Mine is like the second unit they got from Arctic. And now I confirmed it by looking in the box. The majority of Liquid Coolers on the market today are based around Asetek designs, but the Liquid Freezer II features a pump which was designed in-house by Arctic, with the goal of quieter operation and higher efficiency. Like its fans, the water pump is PWM-controlled and will adjust its speeds. This decreases power consumption and leads to lower noise levels in lighter workloads.

Time to move to VRM thermals. Before putting this chart up, a few important points: First, this is all relative, so our measurement points aren’t designed to test the motherboard, but rather to test the cooling capabilities of the CPU cooler on top of it. We’re taking VRM measurements at points that will work better for testing cooler impact, since we don’t care about comparative VRM performance from one board to the next. Second, we’ll show the numbers with the radiator mounted to the side of the bench. That’s how we tested all the liquid coolers so far, as it is more similar to a top-mounted radiator in a case. This means there’s always airflow over the VRM heatsink in all the CLC tests, whereas testing it on the table, away from the VRM, would paint a picture of Arctic’s VRM fan having a higher relative impact since you’d be taking away all cooling otherwise. We have these numbers too, but let’s focus on 3950X OC numbers at 35dBA radiator fan speed first, with the Arctic VRM fan at 100%. The test is also tough to standardize since every motherboard will have different heatsinks and positioning, so although you can mostly extrapolate out a hierarchy, it’s not perfectly comparable to every configuration. And again, please also remember that case configuration is the single most impacting to VRM thermal performance outside of the VRM design and cooling solution. What we’re saying is that this test will create an objective hierarchy, but that in all reality, a couple degrees here-and-there from the cooler won’t really matter much when considering the VRM is unlikely to melt itself in the majority of instances. Thermal imaging from our FLIR ONE Pro camera shows moderate heat soak around the radiator sides and within coolant tubing at 50% fan speed, while 100% fan speed shows good regulation and exchange of thermal load. Given that the Arctic Liquid Freezer II 280 runs so quietly, operating the unit with a good PWM curve should allow for aggressive fan speed without excess system noise.I am just waiting for the 360mm one to be available and then I will buy!!!! Looks very good in terms of performance... Not a big deal since laying the board flat on the table bypasses it, but this could be even easier if Arctic refined the solution with cap screws. On the installation front, buyers should also be aware of the short cables for the fans. They can be connected to the splitter cable (which is sleeved alongside the tubes), but we prefer connecting our fans directly to the motherboard to exercise more control over the fans. This is easily solved with some 4-pin-to-4-pin extension cables. Conclusion It's impressive even the Arctic Freezer 360 has issues cooling a 13900K at full bore... It's kind of scary, really. We also offer to do the rework for you. To have the gasket and copper plate replaced, you can send your Liquid Freezer II to our service teams in Germany or the USA. Plus, our sophisticated cable management hides both the RGB and PWM cables of your radiator fans in the sleeving.
I have a MSI x570 Unify motherboard. For CPU it has only one fan header and a separate pump header. Both can be controlled individually and I’ve used the pump header to control another fan I had over the RAM modules.Arctic has built, thus far, a good product. We need to see how it does long-term, as Enermax has scared us away from firm recommendations on thermals alone. We would recommend the Arctic Liquid Freezer II 280 as a go-to solution over competing liquid coolers, based on thermal and acoustic performance, although we’d also note that most proven (e.g. Asetek, CoolIT) coolers will perform similarly. If you want RGB LEDs, you’re mostly just paying more for them, but should be in the ballpark for performance.
admin said:System builders with an aversion to RGB lighting who seek a liquid cooler with distinct attitude should put Arctic’s Liquid Freezer II 280 cooler on their short list. I just hooked up one of my Noctua 3000 RPM fans and plugged it into an empty harness port. It reported 2700 RPM (from the Arctic fan).So does this mean that the pump and vrm fan are always running at 100% and the only thing that’s being controlled by pwm are the fans?
Great Deal
