I've bought the 420 version but I'm surprised how little PC cases support it, so I started wondering what's the cooling performance difference. Small fans have the reputation of being particularly loud and not very durable; that’s why we set out to develop a quiet, sturdy diagonal fan, especially for the Liquid Freezer II. We’re 100% convinced that this 40 mm fan is just as durable as our other case fans. If the fan doesn’t live up to our claims, our customer service team will send you a replacement free of charge (without you having to replace the entire unit). Steve from GamersNexus explains you the mistakes to avoid while assembling your water cooling AIO in your PC case. 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. The VRM fan clearly does something, and temperature improvements will follow the more even FPM on either side of the VRM heatsink, but we also want to be clear that a top-mounted radiator would also benefit the VRM. This is something we simulate in our test setup. VRM Thermals
AIO : Arctic Liquid Freezer II 420 A-RGB. (offset -A, Top mount, Fan Set to exhaust, AIO came with the fans mounted as advertised). 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. 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.The manual for the case has a good set of example configurations and dimension considerations included.
Our next chart continues with the 3950X 200W load, but allows all the coolers to run at 100% fan speed during the test. This doesn’t move the needle much for Arctic, which seems to top-out in its efficiency at around 1200RPM rather than its maximum 1600RPM. The results were +/-1C as usual, but our average ended up at 50.9 degrees over ambient. That’s not enough of a change, so there’s room to reduce noise level without much loss of overall performance. At the 1610RPM speed, the Arctic cooler ran at 42.5dBA at the normal 20” distance. This puts it about equal in thermal performance to the NZXT Kraken X62 and X72, which run around 51-53dBA, or a perceived noise increase to the human ear of about 2x. Again, that’s perceived to the human ear, not acoustic power, which is a different scale. Either way, Arctic’s solution is significantly quieter at the same performance. The EVGA CLC 360 shows that we’re not limited by our test bench, but also that jet engine levels of noise are needed to drive the temperature down further. 3800X – 35dBA A selection of motherboards interferes with the cooler. Below is a list of motherboards which have been confirmed to have this problem. I have the same case, thermaltake view 71 with a ATX Motherboard, MSI MEG X570 ACE, Had an MSI MAG Series CORELIQUID 360R and it failed on me after 8 months. Arctic doesn't state how much heat wattage are they suitable for, but surprisingly they provide some comparison data. Have you noticed that both coolers achieve the same CPU temp on the graphs Just had a look. With a 360 rad (or any 120mm based rad) on top, you will have the option to mount the radiator either flush with low profile memory or 20mm offset away from the memory. Should be plenty of room.
The scariest thing about Apple’s announcement
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. 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. 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 Plus, our sophisticated cable management hides the PWM cables of your radiator fans in the sleeving.
that is, both keep the CPU temp at 50 degrees in the same hardware setup. There's only a visual manipulation to deceive you that the 420 performs better (the axis starts at 45 degrees).
GLASS CPUs ARE COMING.
nobtiba How to show phone screen on TV or bigger screen while the phone has to use device network to control the device? ( 2) I recently upgraded my Haswell era PC to something more current, and with the addition of a 5950X to my system, I decided to do it some justice with the biggest cooling I thought I could fit in my PC without going custom water loop... As the title suggests, I hope to be informative about certain barriers along the way. Additionally, all coolers shipped by ARCTIC are already compatible with Intel's Alder Lake and Raptor Lake LGA1700 processors. Small fans have the reputation of being particularly loud and not very durable; that’s why we set out to develop a quiet, sturdy diagonal fan especially for the Liquid Freezer II. We’re 100% convinced that this 40 mm fan is just as durable as our other case fans. If the fan doesn’t live up to our claims, our customer service team will send you a replacement free of charge (without you having to replace the entire unit). Thank you for sharing this. I just bought this case and I think 420mm is too much for a first time builder, so I am hoping to mount the 360mm version of this AIO.
Great Deal
