Hi looking for advice on my case fans

nathan9022 · Jan 22, 2017

Hi I'm going to build my pc soon but theres one thing I'm stuck on.My case will have 3 fans but my motherboard only has one fan header so I don't know how I can connect them. I could use a fan splitter but will my mobo be able to handle that many. I don't mind having them connected to my psu running at full speed all the time. I'd prefer that option but I'm clueless on molex connectors so can someone fill me in on how I connect fans to a molex
Thanks

thanks, do you know what sites sell them in the uk I cant find any
cheers

Isn't there Amazon.uk ? Just look for "Molex to 3 or 4 pin adapter".
Here's an example: https://www.amazon.co.uk/Evercool-EC-DF003-Molex-cable-AK-CB001/dp/B009JCGIF6/ref=sr_1_2?ie=UTF8&qid=1485333422&sr=8-2&keywords=Molex+to+3+or+4+pin+adapter

What case & fans are you looking at using ??
There are plenty of options open (im uk too)

You can generally run 3 120mm fans off a single header absolutely safely.
If you're purchasing fans separately the f12pwm PST fans from artic cooling have inline splitters built in to the cables.

Hi I did look but they're all 3 pin and aren't long enough

madmatt30 :

Hi there I'm going to use 2 noctua 120mm fans https://uk.pcpartpicker.com/product/bKFPxr/noctua-case-fan-nfs12bredux1200pwm and a pre installed rear 120mm

madmatt30 · Jan 26, 2017

What case exactly is it though mate ??
Some cases come with molex powered fans fitted.
Also are you going to be using an aftermarket CPU cooler ??
The reason I ask is because if you're using a 120mm CPU cooler then you're better with 2 x twin fan splitters.
Linking the rear exhaust in with the CPU fan & running the intakes separately from the motherboard on a seperate splitter.

This is if what you're looking at is 2 x intakes , 1 x exhaust.

Just let us know your case model is , what fan configuration you intend on running exactly & whether you're going to use an aftermarket CPU cooler & I'll point you to exactly what id use.
These kind of scenarios are my 'bag' mate aa I build a lot of matx htpc stuff that needs to run cool & quiet & most boards only have 1 header.
I've used a lot of splitters & adapters & know which ones to avoid.

madmatt30 :

Ok the case is the BitFenix Neos With Windown and i'm going to use the stock cooler for the cpu
2 intake and 1 rear also is this 3 enough fans for a gtx 1060 6gb and the i5 7500 with stock cooler cheers

madmatt30 · Jan 27, 2017

Those noctua redux are 1w fans mate so you'll have no issue running from a single header.

If you're buying from amazon just take the ekwb splitter as an add-on item at the same time

EK Water Blocks 3831109867914 Black https://www.amazon.co.uk/dp/B00L6M2OSC/ref=cm_sw_r_cp_apa_MOVIybS88E6AX

Can't go wrong for £3 & from ekwb its going to be a good quality cable.

madmatt30 :

Thanks alot mate will 3 fans and the stock cpu cooler keep my build cool when gaming? I5 7500 and gtx 1060 6gb

madmatt30 · Jan 27, 2017

2 x 120mm intakes & a 120mm exhaust ??
yes mate fine.
Lot of peeps only have a single intake & single exhaust,3 fans is what id look at normally in any gaming build myself.

nathan9022 · Jan 27, 2017

madmatt30 :

Ok cool thanks for your help

Noctua fans don't move much air at all.

nathan9022 · Jan 27, 2017

fluked :

I've read that they do, what other fans do you recommend

madmatt30 · Jan 27, 2017

The noctua redux are absolutely fine for case intakes.

fluked · Jan 28, 2017

madmatt30 :

I'm just afraid of the wall of cages blocking the 1200rpm fans.

But to be clear, is this the case design? BitFenix BFC-NEO-100-WWWKP-RP

To be honest, I only deal with 1U/2U/3U chassis, I haven't installed fans in a tower in many years. The towers I do see have a very clear flow of air from front to back (but they have 2 CPU's). For home, I always buy fans rated 2x/3x the rpm needed and drop the voltage down. I have a PWM controller to test the fans before applying the needed resistance value. Resistors would be the cheapest way (but not best), otherwise I'd buy a controller.

Or, just put the 2 fans in and you'll probably be fine

. You didn't really mention any details to figure heat, so you're probably not doing extreme OC or anything.

nathan9022 · Jan 28, 2017

madmatt30 :

Think i'll stick with them

madmatt30 · Jan 29, 2017

Is there any reason in particular you're set on the neos ??
There ate better cases for not much more that actually come with 3 or more decent fans & have much less restricted airflow

nathan9022 · Jan 29, 2017

madmatt30 :

Is there any that you recommend, (preferably with a window) as long as everything is cool.

nathan9022 · Jan 29, 2017

madmatt30 :

How about the Corsair 100R? I can install 2 top exhausts and 2 intakes, (rear) exhaust included) I could buy 4 noctua redux fans but I'm back with the 1 fan header problem again :/

madmatt30 · Jan 30, 2017

Honestly for the £40ish bracket the zalman r1 is a really nice little case.

3 fans included , remove vthe top exhaust one & putbitbinbthe from as another intake then use the twin fan controller built in for the front fans.
You could run that as is with no extra fans or cable to buy.

Moduvent panel on top to allow 2 more fans or a radiator.

Excellent value for money

Step up the z9 neo which is a mentally good case.

5 fans , PSU shroud , excellent quality & just looks great IMO

One of my favourite budget cases of the last year personally.

nathan9022 · Jan 30, 2017

madmatt30 :

I Would go with the z9 but pc part picker says this: Gigabyte GA-B250M-D2V Micro ATX LGA1151 Motherboard has an onboard USB 3.0 header, but the Zalman Z9 ATX Mid Tower Case does not have front panel USB 3.0 ports.

I could go with the r1 and buy 2 case fans?

madmatt30 · Jan 30, 2017

You would not need 2 extra case fans with the r1 in all honesty mate, removing the top panel spoils the case.

The z9 BTW ?? I'm talking about the z9 neo , the z9 & z9 neo are completely different cases (confusing I know)

The z9 has USB 2 only , the z9 neo has 2xusb 2 & a usb3 port .
