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. 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. Er ... this thing costs less than half the price of a h100 pro ... and cools within 0.1 degree (by the data that you yourself linked) ... not to mention PWMs @ over 50% cooler with this AIO. A selection of motherboards interferes with the cooler. Below is a list of motherboards which have been confirmed to have this problem.
The V1 has three fan connectors. Two of them have three pins, with the third pin missing, so only pins 1, 2 and 4 are there. The third connector--the one closest to the radiator, has all four pins.
How is the problem solved?
While it was fairly easy with previous generations of CPUs for coolers to keep the flagship i9 processor well under TJ max (the maximum temperature a CPU can sustain without throttling) in tough workloads, this is no longer realistically possible with the Core i9-13900K without extreme cooling (or enabling power limits). While in the past a CPU hitting its peak temperature was cause for concern, enthusiasts are going to have to learn to accept high temperatures as “normal” while running demanding workloads with Raptor Lake and Ryzen 7000 CPUs. I am just waiting for the 360mm one to be available and then I will buy!!!! Looks very good in terms of performance...
I prefer Noctuas, specifically the NF-A12x25 for 120mm for noise/performance, and the Noctua iPPC fans in either 120 or 140mm and whatever speed choices they offer. But they can get pricey and you can easily pay more for fans than you did for your AIO. The next test will be for the VRM fan. For this, we’re going to start with an overlay demonstrating the linear feet per minute flow, often called FPM or LPM, as measured with a hotwire anemometer at the edge of the chassis for the cooler. The measurement is taken at an angle toward the VRM heatsink. We measured at a few points and under a few conditions. I separated the fans from the pump and connected the radiator fans to cpu fans and the cable coming from the LFII into the pump header. I am not getting any pump RPM value. I thought it may be because it could be a 3-pin “fan” but even still I should have RPM value. I have used that header with other pwm fans in the past and it read RPM no problem. This one in the review looks really nice as well. I wish more manufacturers would stop making their products look like action figure toys.

The illuminated P-fans are already mounted on the radiator from the factory. During the development of the new P-series fans, special emphasis was placed on a focused airflow and thus a high static pressure. The fans guarantee extremely efficient cooling, even with increased air resistance. Therefore, the P-series fans are particularly suitable for use on heatsinks and radiators. This seems like a top contender for the best 280mm AIO. Great job on Arctic's side of things. The only thing left to test is whether or not there will be more or less horror stories with them, as well as, how many are DOA and the longevity of each cooler. 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. It's 100% "Harness" speed on the V1 that is reported on only one of the fan connectors. It's not pump nor VRM. They don't have a sensor at all. B) it will be difficult to run a push/pull due to the sheer size of the radiator depending on your case. I BARELY got it all to fit.
The Liquid Freezer II's fiber-reinforced 45 cm tubing allows for installation even in large cases and effectively prevents coolant evaporation, so you don't have to worry about refilling your compact water cooling system. Should be available in Europe -- I'm pretty sure Arctic is a European company -- based in Germany maybe?Plus, our sophisticated cable management hides both the RGB and PWM cables of your radiator fans in the sleeving. Installed this about 2 months ago. Quietest AIO I ever used all why keeping temps lower than my Kraken X72.
I've got the LF 360 v2 and I'm having the same problem. The pump is working but no RPM is reported to mainboard. It's connected to the pump header and the fans to the CPU fan header. The lowest power limit I test at is 125W, mainly because this is also the lowest level where I can reliably measure noise measurements. Lower power consumption causes the noise of the CPU cooler to fall below the noise created by the system fans (even while restricted to 35% speed).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 The nature of a review cycle (while a product is relevant) typically dictates that there’s no means to realistically test for endurance or age. We can revisit in the future if needed, but that’s the only question mark left after the review process: Arctic’s pump design is new, something we’ll look at in our tear-down video coming up shortly, and a new design means we have no reference point for endurance and reliability. In general, liquid coolers outlive the usable life of the system, and potentially two systems, but those that fail do so in a much more visible or catastrophic fashion. Failures are overall rare, however, and that’s always important to note. We’ll send you to our Air vs. Liquid cooler content for more of an explanation on this front.
