Before Arctic transitions to its new, 7-blade fan design, let’s take a closer look at the one that has characterized the company for many years. And even though the 5-blade fans of the “P” series had certain shortcomings, they demonstrated just how efficient even low-cost designs can be. In the case of high-speed models, such as the tested P12 Max, they also show how far cooling performance can be pushed.
Results: LED-to-motor power consumption ratio
Explanatory note: Lighting components significantly impact fan power consumption. These charts show the ratio between LED power consumption and motor power consumption across standard operating modes (from 31 dBA up to maximum RPM). LEDs are consistently set to maximum brightness. Lower ratio values mean lighting comprises a larger portion of the total power. This is not inherently negative–higher LED intensity can be advantageous and is typically adjustable. Details about LED control options are provided in the previous chapter.
Why is a value sometimes missing for a fan? There can be several reasons. Most commonly, it’s because the fan couldn’t be regulated to the target noise level. Some fans have higher minimum RPM (or they spin slowly but have an excessively noisy motor), or they are simply slower models that can’t reach higher decibel thresholds. Results are also omitted from graphs if the rotor scrapes against the mesh of a nylon filter. In such cases, we classify the combination as incompatible. And of course, a zero in the graphs naturally appears in situations where we record an actual 0.00. This often occurs at extremely low speeds when obstacles are present or during vibration measurements.
Overall quite similar behaviour (at same noise levels) vs the ARGB variant. Not too much compromise at lower speeds unlike the P14 Max, which is good to see.
One thing I just noticed is the different stator ribs compared to other fans in the Arctic P family. Now they’re thicker and straight (like many other fans) rather than thin and curved. This perhaps sacrifices a tiny amount of airflow but is needed for supporting the higher RPM and rotor weight.
Good point. The P12 Max fan is about 20 grams heavier than the P12 A-RGB. And it doesn’t even have any LEDs, which also add some weight. While we don’t know the exact difference in material density – since the P12 Max uses PBT for its rotor and the P12 A-RGB likely uses polycarbonate – there’s definitely some variation happening at that level too. 🙂
it seems the spam filter worked better with the older version… the Indonesian university bot seems pretty persistent (that’s the 3rd time I’ve noticed it) 😉
… I’m attaching the response to this thread so you don’t have a problem deleting it
so now, I’m really curious if there will be any answer 😀
…now you chose a different approach instead of deleting… we’ll see 😉
