TLDR:

• Noctua NF-A12x25 is the best at of all tested
• It's the quietest at 33.1 (500 RPM) to 44.8 dBA (2000 RPM) vs the category average of around 33 (500) to 49 (2000)
• Case testing shows the Noctuas at 35 dBA vs the category average at around 39 dBA
• When all fans are at 40 dBA, the Noctuas run the fastest (1680 RPM vs 1300 RPM) while having the lowest temps (80 vs 85 degrees)
• The Noctuas also runs the coolest and faster at the same 35 dBA as other fans
• People who will see the most benefit are the ones that run their fans at more than 1200 RPM, particularity in ITX builds where you only have 1 or 2 fans

>Who Actually Makes the Best PC Fans?

Best PC radiator fans you mean? The scythe kaze flex which he thought was bad, is actually pretty decent as a case fan.

Weird to not include other top fans like phanteks and arctic...

​

So the title is pretty missleading.

I have no doubts the NF-A12x25 are the best performing fans, but I am not convinced they are worth the cost.

The difference to some other fans is marginal at best and the cost is substantially higher.

I am interested in performance per dollar as well.

For instance putting 4 fans on a radiator, it's $120 for 4 NF-A12x25 PWM vs. $40 for 4 Arctic P12 PWM fans.

I am not sure it's worth $80 more for slightly lower temps, because I can certainly slow down the Arctic P12 to a point where they are very quiet.

Their F12 fans aren't bad, either. Significantly quieter than the Noctua Redux fans they replaced while delivery the same amount of performance.

Yes. $7 and is as quiet up to 1200-1300RPM and negligibly louder and worse performing above that. For most people it's 90% of a NF-A12 @ 1/4 the price. Or you can buy 5 for the price of one NF-A12.

I'm actually glad that they offer the chromax or whatever they call it because I can't stand the beige and brown.

I'll be grabbing the chromax and done of those white fan coverings they sell when I build my new PC

Phanteks no idea, but the Arctic P1X ones are insane, they are part of the reason why their CLCs are topping the charts at GamersNexus on the noise normalized testes (and the thicker radiator too).

That being said they probably are not better than Nocuta, but they are very close and super cheap. You can get 5 packs for under 30€/$.

Best performing case fan for what? Filter or no filter? Radiators or not? How large is the case?

Airflow, noise, cable management?

As the owner of a 7xT30 machine, they are the bees knees. My 5800x3D and 6950xt machine is running on full use at low temps. I can crank it to 3000 rpm if I really want or need to cool everything off faster but the fans output like crazy at 1000-1700 just fine. The coil whine from my 6950xt is louder than the fans under load. Cushioning is good. If I could do it again I'd wait for the new daisy chain connection points they just showed off on the standard T30, I don't need rgb or reversed fans for aesthetics.

Nope. This hair splitting is a cope used by people with inferior fans. The T30 is the undisputed best fan currently.

p12/14 if there is a filter involved, its a cheap and silent fan, that performs very well.

if there is no filter or noise is highest priority, arctics f silent series are great contenders.

Noctua A12x25 is what you are looking for. Best performance per noise ratio, good performance in all use cases and no RGB. The only downside is the price.

Eh, I disagree. It’s important to understand that whenever sound is involved there actually is a level of subjectivity that you need to account for.

Higher airflow and lower dBs certainly gives the T30s the crown on paper… but after A/B comparing the two (any others) in person I still give the crown to Noctua any day. The noise profile on the A12x25 is simply superior, even when it’s slightly louder than a competitor.

Noctua fans in general, move a fuck ton of air.

Wearing mine today!

Where did you get the fan?

Spray through the radiator grills while keeping the bottle straight. Hold the fans so they don't spin. Clean the dust using a brush. Should be enough for a legion.

Tape the fans! You dont want them spinning faster than they are designed to. It will ruin them.

I cleaned my laptop like this thrice without ever disconnecting the battery. Not saying what I did was right, just that I didn't have any problems.

The proper way is to remove the fans and clean them separately.

It will have a better result. the only critical thing is if the paste is still pliable, great.if not replace it with something of OEM quality and you'll have as good if not better performance.

Checking CPU package power/clock during cinebench will tell you the story. before vs after.

If you can't take it off, then it doesn't matter. Do what you can I guesz

Well...I'm sure I'll get down voted but step #1 remove the fans then heatsink. It's the only way that doesn't force dust deeper.

...never ever use a thin paste like mx4 on these btw

Was it easy or hard to pull out the connector? I haven't done it on mine yet.

I have on other laptops in the past. Desktops.

It's only suitable on desktops where 80C isnt seen.

It rapidly pumps out over 80 (where laptops occasionally venture during benchmarking)

Too thin.

Do not use on laptops. Many other better alternatives

I love it so much I bought another. 10ah battery lasts about 10 hours. Highly recommend the fan.

It's a 22w fan on max. So it's pulling about 1 amp at 20v. So every amp hour on a battery should be close to a 1 hour run time. 5ah battery = 5 hour runtime, 6ah battery = 6 hr runtime. Approximately of course, it will be about 5% below this rough estimate.

$65 With a 5AH battery… I bought 2 last month. They last a while with that 5AH because I left it on overnight at a low speed and it didn’t die. 🤷‍♂️

Yes, they work great and last a long time. Use mine constantly. So many uses aside from just cooling off too.

$89 with 5ah and charger at Lowe’s a while ago!

I got three for work and two for camping

Just to throw this out there, you might consider the previous version, which could take AC power. I got mine for $50 used.

yeah this thing is like a propper hoover. i clean this thing every month

Fortunately it doesn’t take an engineering degree to do this. It’s like six screws. Just be mindful of accidentally hitting the power button . It seems like A delicate fan

You guys must live in some dusty environments. My legion go is a year old and I cant see a single piece of dust on my fan.

If you're using can air or other air source, hold the center of the fan so that it doesn't spin freely because then it turns into a generator creating electric charge that goes the wrong way into the system. Can kill electronics that way. Never let a connected fan free spin from can air duster.

Yeah

Prob a good reminder for anyone with any portable device (be it legion go, laptop etc etc)

>I wanted to maximize the vibes and cooling performance u/theoneandonlysauce

Nice! Am sure the RGB lighting drops the temperatures by another 5°-10°C for sure!

That cooling pad is not really compatible for your zephryus. You should get one with more fan surface, like ilano v10 or v12, which essentially puts your laptop above 1 giant industrial grade fan

When the designer cares more about aesthetics than performance:

I'm not familiar with this brand, but even if the fans are super-duper strong, the vents appear to be working against them 🫣

those cutouts are probably blocking about half the static pressure of the fans lmao

LLANO V10 for the G14 and V12 for the G16. The IETS is really the only other fan that does more than a few degrees of cooling for these laptops.

Got the exact same laptop, but with the llano cooler. G9t the sane results as well, hella happy i bought this cooler. Side note, are you able to turn on your rgb through vantage or the command keys? I tried almost everything and i still cant get lenevo spectrum or have my keyboard lights turned on.

If sound is a problem the flydigi 2 is out and I get better performances from it than I did with the iets with much lower sounds

I bought "Arctic P-12 0db rgb pwm" to replace my stock exhaust fan. It's pretty quiet and was cheap too so i can recommend

Noctua NF-S12B, BeQuiet Silent Wings 3, Arctic F12, Gelid Solutions Silent 12, Scythe Kaze Flex 120mm. All of those are great if you want a quiet PC. Check out: https://www.quietpc.com/casefans

noctua a12x25

Arctic P-12 PWM. You can chain link them together.

Also dear OP I found perfect topic for you from asus redit
