Let's talk fans?

[StoneCold]

12cm or 10cm or mult-fan bays

[DotEXE]

Definitely 12cm. Without leds if you can ?

[error.404]

In 2026 LEDs are so over. No cap

[Northernah]

My rooms lights up from the leds inside it's like a 70s psychedelic lava lamp

[DotEXE]

The rpm is key. And on your motherboard so you can control the speed. Mine is set to turbo

[Myles]

From what I saw that checks out. There is usually a quieter more important story sitting just behind the obvious headline.

Curious to see how this develops

That is the sensible approach. Might save you more than you think

[GhostRider63]

Not sure I am fully with you on that one. Nice one

[Daemon82]

Makes sense. Proper useful that

[Daemon55]

Yeah that is about right. Good shout.

A lot of people confidently recommend things they tried once and never followed up on.

Ha, fair enough.

[Mesh Ross]

Honestly 12cm fans are still the sweet spot for most builds.

You get a good balance of airflow and noise without needing to overthink it.

Unless you are building something tiny or very specific, there is rarely a reason to go smaller.

[TealBear]

I am going to be that annoying person and say 14cm fans are underrated.

People stick to 12cm out of habit, but larger fans can move more air at lower RPM.

Less noise, better thermals, and your ears will thank you.

[Cheeky Blake]

10cm fans feel like a relic at this point.

Unless you are dealing with very tight OEM cases, they just do not make sense for modern airflow setups.

I only ever see them when I open up old prebuilt machines.

[Cheeky Kernel]

Multi-fan bays are a bit of a trap in my opinion.

More fans does not automatically mean better cooling.

Airflow direction and case design matter way more than just stuffing everything full of spinning plastic.

[Anvil]

I recently switched from three loud 12cm fans to two high quality PWM ones and my PC got both quieter and cooler.

It really showed me that quality beats quantity every time.

Cheap fans are just noise generators with extra steps.

[Ryan84]

Hot take: RGB fans have ruined fan discussions.

Half the time people are prioritising lighting over actual airflow performance.

Your case looks like a disco, but your GPU is still cooking.

[Anvil]

I actually enjoy tuning fan curves way more than I should.

There is something satisfying about shaving off a few degrees without turning your PC into a jet engine.

It is basically the adult version of tinkering with Lego.

[VoidRanger24]

One thing people forget is static pressure vs airflow fans.

Not all fans are equal, even if they are the same size.

If you are using radiators or tight filters, this matters a lot more than people think.

[Seb83]

I still run 10cm fans in an old HTPC and honestly they are fine for that use case.

But I would never recommend them for a gaming rig in 2026.

They just cannot keep up with modern heat output.

[Amy96]

The funniest builds are the ones where someone installs like eight fans and wonders why it is louder but not cooler.

Airflow chaos is a real thing.

More spinning does not fix bad direction.

[Gaz90]

If your case supports it, front intake 12cm fans plus a good rear exhaust setup is still the most reliable configuration.

Simple, effective, and proven over years.

Sometimes boring is exactly what you want.

[Baz_26]

I tried going full "positive pressure optimized airflow" once and ended up spending more time cleaning dust filters than gaming.

It works, but it is definitely a lifestyle choice.

Not sure I am ready for that level of commitment again.

[NovaPrime68]

No one talks enough about fan bearing quality.

A good fan with proper bearings will outlive your entire upgrade cycle.

A cheap one will start sounding like a dying fridge in six months.

[EntangledOne]

At the end of the day, 12cm fans are the default for a reason.

They are easy to find, cheap, and compatible with almost everything.

But there is definitely room to experiment if you like tweaking your setup.

[RoughDaemon]

My honest advice: stop overthinking fans unless your temps are actually bad.

Most modern CPUs and GPUs will handle reasonable airflow just fine.

Half the time people upgrade fans just for the dopamine of tinkering anyway.

[Marnie80]

12cm is basically the sweet spot now. 10cm feels like a relic unless you are dealing with an older case or something very compact.

Bigger fans move more air at lower RPM, which means less noise for the same cooling. That alone makes them the default choice for most builds.

Multi-fan setups look impressive, but beyond a certain point you are just adding noise and complexity without real gains

Good airflow beats more airflow.

[Quiet Glacier]

The "stop overthinking fans" advice is spot on for most people. Temperatures are fine, system is stable, yet there is still a temptation to add two more fans "just in case"

At some point it turns into a hobby rather than a necessity.

Nothing wrong with that, but it is worth recognising when you have crossed that line.

Otherwise you end up tuning fan curves for fun instead of solving a problem.

[Steve59]

Case layout matters more than fan count. A well-designed airflow path with two or three decent fans can outperform a chaotic setup with six.

Front intake, rear exhaust, and maybe a top exhaust if the case supports it.

Keep it simple and it usually works.

Air needs direction, not just enthusiasm

[RogueJaguar]

Noise is where fan choices really show. Cheap fans can move air, but they often sound rough doing it.

Better brands like Noctua, be quiet!, or Arctic tend to have smoother acoustics.

It is not just volume, it is the quality of the sound.

That constant hum vs random rattling makes a big difference over time

[Gateway Warden]

RGB fans are a whole separate discussion. Performance is often secondary to how they look.

Nothing wrong with that if you are building for aesthetics, just do not expect miracles.

Some of them are perfectly fine, others are all flash and not much airflow.

Style points do not lower temps, sadly

[QubitZero68]

Fan curves are the real secret weapon. Default settings are usually conservative or inconsistent.

Tweaking them in BIOS or software can reduce noise without hurting cooling.

A gentle ramp-up feels much better than sudden bursts of speed.

Takes a bit of trial and error, but worth it.

[EventHorizon63]

Dust management rarely gets mentioned enough. More fans can mean more dust if filters are not in place.

Positive pressure setups help keep things cleaner by pushing air out of gaps.

Less cleaning, longer component life.

Not glamorous, but very practical
