Good Gaming PC – RGB fans that show temperature and system usage

Recently we teamed up with our friends at PB Tech for a quick YouTube Guide on How to Make Your PC Dust Free and in this we used their cheapest RGB triple fan kit, the Segotep RexGB to sidestep the issue of running out of fan connections on a motherboard so the video would be more helpful.

Now this led to a question on why it was significantly cheaper? compared with something like the Cooler master MasterFan Pro Triple Fan Kit ($48.99 vs $138.99 at time of writing this)

Before we get into the advantages offered by the Cooler Master Kit below is a quick video showing some of the lighting options offered by the Segotep RexGB.

We can all agree the Segotep RGB fan kit is pretty awesome to look at and they definitely provide excellent cooling for the price also, however… The Cooler Master MasterFan Pro RGB fans can be used to allow for a visual indication of system component usage, PC heat levels and more! When you install the Cooler Master fans, you’ll notice these have two cables coming off each, one is a standard 4pin fan header and another is a special RGB header connection – the kit also includes a HUB but we won’t use this for AURA features so be sure you’ve got 3x fan headers ready to go.

This connects to the RGB header on our motherboard, not all motherboards have the right version of these though, double check the motherboard says either AURA for Asus and FUSION for Gigabyte or Aorus.

In our testing system we’re running an Asus X370F Motherboard which only has 2x RGB headers, however, so we’ll be adding in the Cooler Master 1-3 RGB Splitter Cable – this will leave one of our motherboard headers free for future upgrades too. (TIP! There are little arrows on the RGB cables that align as shown in the image below, if you do one of these backwards the colours won’t sync!)

Because we’ve got the Asus Motherboard we’ll be using the software package called AURA in our guide, looking at the Cooler Master Fan box again you’ll notice this logo appears here as well.

Before we get stuck in there are videos to check out showing the various modes in action, below are quick GGPC Instagram links to check out

Finding the AURA software package can be a little tricky, it’s not on the official drivers or utilities website for your motherboard or your fans – instead, you’ll want to go to this dedicated Asus AURA Download page, then select the download tab up top, then select the most recent version to trigger the download.

This will download as a zip file so unpack that, then run ‘setup’, it’s small and quick.

With our Aura software installed, you first need to calibrate our RGB before jumping into the special features. To do this simply select the ‘Settings’ tab in AURA, then click the calibrate button, from here it will ask you what colour your fan is, after you select each option it will change the colour and ask again, very easy!

How to calibrate your RGB Header with AURA at PB Tech

let’s start off with something useful, system component usage. Using these settings we can choose the colours displayed when the PC hits various marks under stress – at idle it’s a calm green, firing up moderate task gets us into a cool yellow, so we know our PC is processing things, but it’s still got plenty of power to use, firing up big game gives us a vibrant red signalling we’re using everything our PC has to power this task.

Looking GOOD and also useful!

How about temperatures? For this one, it turned out to be a tough demo to do because along with all this RGB the fans also provided excellent airflow through our chassis… In the end we have to tweak our lighting zones markers as shown in the sliders below and even blow hot air into the PC via our trusty custom water pipe bending gun!

Pretty cool right? or maybe hot… anyways!

This is made possible by the technology built into the motherboard, and fans aside for a brief moment this same software can control other AURA ready components connected to the motherboard like our G.Skill ram, and it’s easy to sync every compatible part all from the one software package, this can be used to make your PC dance to music and all the usual pulse, strobe strobe, flashy flashy stuff.

There’s a lot more that can be done with Asus AURA with a little tinkering too, it’s actually pretty limitless as those fine folks at Asus also made the software development kit available.

We hope you enjoyed this quick guide on RGB PC fans with a purpose, be sure to keep your eyes on our Gaming PC Blog for the latest!
