But they might be good for a thick radiator.

Core 140 @2500RPMS.

Although loud, louder at the upper end, it has great static pressure.

I'd love to see TPU do a review/comparison between these alphacool 3000 and 4000 rpm fans and the Noctua NF-F12 industrialPPC-3000 rpm and the NF-A14 industrialPPC-3000 rpm.

When comparing the listed specifications, the Alphacool 120mm 3000rpm fan has less airflow, but better static pressure than the 120mm 3000rpm Noctua industrial fan so I'd be interested to see how these fans compare on a radiator/AIO. I'd also like to see the 4000rpm alphacool compared to the 3000rpm Noctua.

**The price on the alphacool fans is A LOT lower than the Noctua fans, so it'd be interesting to see if alphacool could match the performance.

Bearing type? I assume FDB or maybe rifle.
These look ridiculously cheap but if they're reliable and work well, that's fine. A cheap 120mm fan running at 4k RPM is a bit concerning.

These look like cheap fans. And they are actually pretty cheap fans. Id still take an Arctic P12 or P14 though.

The noctua industrials are crap though. The phanteks t30 and the a12x25 are the go to 120mm fans.

Hi,
Windy, they are having fun with naming :laugh:

Nice and cheap. I can't tell if the screw holes in the corners have rubber inlays or if that's just a mould mark.

Either way, these will be on the loud side; 7V starting voltage and 2500RPM means that the minimum fan speed is probably 1100 or something like that. IME 8-9V is usually half the maximum rated RPM and it's absolutely not a linear relationship.

Forget that each time they review a fan they stop at like 1500 rpm . If they ever review those fan they will say "oh their are loud and have bad noise/performance ratio at 1500rpm". They doing that with all fan clearly not destined for that type of use.

MachineLearningA cheap 120mm fan running at 4k RPM is a bit concerning.

Come on, what could go wrong? :D

We all like those delta noise imitations.

Why would you say that. I replaced a Phanteks 140mm with a Noctua 3000 RPM and it improved my temps. Yes it is audible but it is running at 1800 RPM on PWM.

I don't know what fan you replaced with what , but the only good noctua fan is the a12x25. The industrials are outdated and they lose to performance to noise ratio by a lot of fans.

If you need more RPM to cool, you're doing something wrong. :D

I will tell you what I did. I took off the chipset heatsink and replaced the thermal pad. That was when the adventure started. As I have said before I have a tremendous amount of I/O running through the chipset as well. When I turned back on the PC the chipset would sit in the 80s. I even replaced the pad with different material but no success. I also have my AIO rad on the side panel with some 3 120s pulling air. I do believe that was causing a minor wash in that area. When I got the Noctua it actually improved it by about 7 degrees and I can feel the air coming through my GPU at the back much stronger. Part of it is the design of the case as the bottom mount sits about 3.5 inches closer to the side panel vs the MB tray. I since added a 80MM Noctua but it is a little too big with expansion card I have in the 3rd slot (That idles at 50 C). So on Amazon this morning I picked up one of these. I was reading reviews and it seems that Noctua have the acoustics for small fans solved.

Having just got 3x of AC's 2500RPM aurora fans, i can at least vouch for them and say they quiet down nicely at lower RPM
They could be used to fly a drone at full speed however, lotta airflow

4,000RPM? They'd go into orbit, pretty much industrial fans like the famous finger-chopping deltas

I had to replace the thermal pad on my x570 boards chipset, first board I've ever had to do that to - and so much hardware (like PCI-E lanes) runs through them they really do need to be cooled properly these days or weird things can happen
thickness matters so much, even 0.1mm too thin or too thick can make or break how they perform

So, a while back, I discovered these fans while researching fans. All I was really looking at was the airflow, and these guys are the kings. So, I bought a bunch of the 4000RPM models for my case and CPU coolers. I originally thought the noise wouldn't be a big deal - until I bought one. I figured that I could tolerate some noise, but holy hell, it sounds like an airplane taking off. I could hear my PC two rooms over in my bedroom - even when on the lower end of the airflow curve! Also, if your fingers get anywhere near it, you're gonna lose some flesh! Like more than band-aid level. I stuck with it for a while, because of the amazing performance and learned to try to ignore the noise. Then they ruined a podcast I recorded, which was the final straw. I bought some of the Arctic P12 Max, and don't regret it for a minute! Night and day, though I do miss the performance.
