Lian Li - LANCOOL 207 few questions

[Krit]

Hello everyone,

I have few questions about Lian Li - LANCOOL 207 case.
- This case have 2x 140mm x 30mm (non standard) stock fans in front. Is it possible to change them to standard ones 140mm x 25mm and if they will fit (holes will line up) ? And do i need to buy different bolt length for it or it comes with it already?
- What's the cases (contact) feet width ? I know that case are 219mm wide but my case stand supports only 210mm......
- For 99€ it's a decent buy ?

The 140mm is the key point here. The spacing for mounting to the case will be the same. And you almost always can go thinner. Going thicker is where compatibility issues might arise.

As far as screw lengths, only you can answer that because only you are right there to see. So I say, try and see. But it seems to me, if the screws worked with out interfering with the 30mm fans, I don't see why they would not work with the 25mm fans.

Maybe someone have exactly the same case with already installed different front fans ? I looked on google and youtube and found nothing at all only original ones that's strange because original ones definitely aren't so great fans in terms of noise output. There are probably some compatibility issues with wiring right....

No. There are only a couple different fan connectors but beyond that, they are wired the same. If one thinks about it for a second, it just makes sense they have to be standard because we can use just about any ATX compliant power supply with these cases as well as just about any ATX compliant motherboard.

Check your current fans and get new fans with the same connector.

I mean physically may not fit (fan wires limited space) it's not about connectors.

 

[Bill_Bright]

What limited space?

I don't understand your confusion. I already explained how any 140mm PC case fan will fit in terms of the mounting screw spacing. And it should just be simple common sense to see that any 25mm thick PC case fan can replace a 30mm thick fan.

As for cable length, surely you know how to use a ruler to measure your current fan cables. Then simply read the specs of any new fan you are considering to make sure its cable is long enough. Obviously, if your current fan has a 12" cable and uses most of that length, you don't want a fan with only a 6" cable. And if the replacement fan has a 15" cable, it is no big deal to tie back extra length. I just would not get a fan with a 24" cable if I only need 12". Technically/electrically, no big deal. But good cable management looks more tidy and more professional, and minimizes impacting case cooling/air flow (or collecting dust).

Out of curiosity, why are you replacing these fans? You say you don't like the "noise output". As someone who really hates fan noise, I can definitely sympathize with that.

But I would expect Lian Li supplied fans to be pretty quiet. And since that case comes with 2 x 140 mm x 30 mm pre-installed in front, and 2 x 120 mm pre-installed in the bottom, unless you are doing some extreme overclocking or your ambient (room) temperature is an oven, you should have adequate case cooling.

I note one of the main reasons most case designers moved from120mm fans to 140mm fans is 140mm fans can move massive amounts of air while spinning at a lower speed than similar design 120mm fans. And the lower the RPM, the quieter fans become. And being 30mm thick, that means the blades act as bigger scoops to grab and push along even more air at the same or even lower RPM. That's a good thing.

Have you tried simply slowing these fans down? Front fans are great but they are right there in front, typically closer to our ears. If slowing down increases your internal temps too much, you might be able to simply add a quality 120mm fan in back to help exhaust heated air out. This might allow you to slow down (and quiet) the front fans and still provide adequate cooling to the components inside. You still want to maintain a slight over (positive) pressure in the case to ensure intake air is pulled in through the air filters, so a single fan in back would probably be best. Any more and you may end up with an under (negative) pressure. That is not good because it causes a slight vacuum in the case and that will draw [dirty] air in through every crack, crevice and port in the case. Not good.

Note a major component of fan noise is NOT from the fan, but from the air from the fan being drawn/blown through the vents in the case. Replacing a fan with a quieter fan does nothing to decrease the noise of the air molecules banging into those vents. Only decreasing the amount of air flow helps with that.

Instead of using mounting screws, you might also consider using fan anti-noise, vibration isolators instead. These help suppress noisy fan vibrations from resonating throughout the cavernous case.

Now i'm considering to buy this case (never used one) seems to be it has good quality for decent price. Previously, my favorite cases were Fractal Design and XPG (decent quality for the price at least in past) let's see what Lian Li will offer. I had used many different fan brands and my all time favorite by far is Arctic P12 hopefully P14 will be the same. I even tested P12 vs P120 Bionix at some point and P12 had quieter engine at low rpms! I never rated stock fans usually they are loud and quality is not great.

That's the best answer right here! This my help for fan cable management/spacing.

It's all about undervolting and maximum quietnes that's way i will change stock fans. For me overclocking is past.

Lian Li makes great cases but IMO, they are overpriced. They were one of, if not the leading pioneer in aluminum cases back in the day, but those innovative days are long gone. I now go with Fractal Design - and I've been real happy with FD fans too.

That's the best answer right here! This my help for fan cable management/spacing.

Huh? I don't see how these can help with cable management or spacing. They just minimize vibrations from being transferred to the case.

Well, just because a fan comes with a case, that does not mean it is not a quality or quiet fan. The only way I know my FD case fans are spinning is if I put my ear up to the back of the case and "feel" the air hitting my ear. My CPU and GPU fans (when they ramp up - which fortunately is not very often) are bigger offenders. But the built-in sound deadening lining of the FD case does an excellent job of suppressing most of that. My PSU fan only comes on when the PSU is really taxed and that is not very often either.

One the best ways to reduce fan noise is to add another fan and slow down existing fan speeds.

Typically, if I am putting a big demand on my computer, enough to cause the fans to ramp up, I most likely have my speakers turned up too with Springsteen, Marshall Tucker, or Zeppelin drowning out any and all objectional fan or background noise.

Devil hides in details! This case is not some average case..... Pay closer attention

 

[Bill_Bright]

LOL. Please - that case is nice, but nothing special.

If your current mounting screws are interfering with your cable management and spacing, you are mounting them wrong or have failed to route your cables in an appropriate way.

You are right. The devil is in the details. Pay closer attention to how those silicone anti-vibration rivets work.

Time to move on.

Finally i found who talks about it. Fan mounting construction is different thick cables may not fit P14 have thin cables but still under big question. Cable management is also under question.

 

[Iain Saturn]

And yes I own it,
And yes swapping the fans would be foolish. Very quiet and effective

Will see i have feeling that Arctic P Series will be better than these stock fans in terms of noise output.

What's your PSU dimensions ? I have Sharkoon Rebel P20 750W ATX 3.1 140mm lenth one of the quietest PSUs in the market right now.
