Why to choose an AIO Liquid Cooler?

Liquid Coolers have become very popular nowadays and they have become one of the most essential parts of a gaming or workstation PC.

As a matter of fact:

All In One (AIO) Liquid coolers are now bought for mainly CPU cooling and to give an Aesthetic look to the PC.

But you may ask, why AIO?

Well, AIO liquid coolers are easier to install than custom liquid cooling kits. They require less space and power consumption too.

And most importantly:

AIO Liquid coolers save the CPU temperature from the heat of the other components.

Overclocked RAM releases a good amount of heat and it is harmful for the CPU. 

But it really doesn't matter:

If the PC case case is very well ventilation like the Bitfinix Enso.

Before going further more let us know why to choose a liquid cooler first.

Cooler Master ML240R Overview

Cooler master has launched their new coolers ML240R and ML120R with some new features.

The new features are:

The dual chamber design of the pump, which separates the cooler liquid coming inside the pump from the hot outgoing liquid.

The new sleeved tubing design which is flexible and long enough for most cases.

And it also looks very premium.

The best new thing is:

The ML240R comes with ARGB lighting. The two included ARGB fans and the ARGB illuminated Pump looks very gorgeous. Now you can get rainbow like effect from your liquid cooler too.

This cooler comes with a 240 and 120 mm radiator.


Note that: The ARGB spectrum effect only support the ARGB compatible motherboards.

But there is a secondary option to control the lighting of the cooler. And you can do it with the included controller. So, you don’t need to worry for any lighting issues.

This AIO cooler's pump looks more fascinating beside the Trident Z Royal RGB RAM.

Another thing I really love about this cooler is:

The logo on the pump is detachable and you can set it as your wish. This feature helps you to keep the logo in its appropriate direction.

Installation Tutorials for Cooler Master ML240R

How to connect the fans and pump of the ML240R?

A fan connecting 4-Pin splitter is included with the package which you need to connect the fans to the motherboard.

Then you need to connect the pump to the motherboard in pump connector if available. If it’s absent in your motherboard then you can simply connect the pump to the CPU fan header.

How to control ARGB /RGB of the ML240R?

First of all:

You don’t need to use the given ARGB controller if you are using an AURA Sync, RGB Fusion, MSI Mystic Light Sync and Poly Chrome Sync compatible motherboard.

If you are using any motherboard compatible with these softwares then you just need to connect one end of the ARGB splitter to the motherboard directly through the 3-Pin ARGB connector after connecting the other ends of the splitter to the fans and the pump. Then you can easily control the lighting of the cooler by using those softwares.


But what if your motherboard is not compatible with those softwares?

Then you need to use the controller given with the cooler.

How to connect of the ARGB controller of ML240R?

First of all let us see the connecting ports of the control box.

The good thing is:

You don’t need to use all of these ports.

So, on the right side of the controller you will find 3-Pin male connecting ports where you can connect the ARGB splitter with the help of the female connectors which are included in the package.

And then you need to connect the other side of the splitter to the Fans and the Pump.


After that, you need to give a SATA connection to the top of the controller from your PSU.

Next you need to connect the micro USB port of given cable to the bottom of the controller and the other end of the cable to the converter of USB hub of the motherboard.

The last step is to connect that USB hub to the motherboard.
