Deepcool Captain 240 EX AIO Liquid CPU Cooler Review

Jump To:

Installing the Captain 240 EX Liquid CPU Cooler

This page will be rather brief, because Deepcool (Gamer Storm) has made the Captain EX series completely tool-free, and this will make for a rather simple installation.  Quite frankly, though, I would highly recommend you use a screw driver to tighten the mounting screws.  However, the other parts for installing the mounting system are absolutely done without tools and very quickly.

I always start off by cleaning the CPU with a high purity rubbing alcohol to ensure any old paste is removed and any contaminants are gone.  I am using the factory paste for this cooler.

Deepcool Captain 240 EX

To start the installation, I took the back plate and stuck the screw bolts through on the 115X hole.

Slipping it through was easy enough, though there is nothing provided to “stick” it to the back of the motherboard.  I think friction will be enough to get this started and would recommend either holding your hand underneath or just standing your system up.

I followed that up with installing the thumb nuts to hold the back plate in place.

Next I slid the Intel mounting bracket across two screws.  Depending how you are installing the cooler, you will mount these horizontal (as I did) or vertical.

Finish that up with the screw cap and you’re ready to install the block.

But first, let’s get that radiator up.  It’s as simple as lining up the mounting screws to the mounting area of your choice in your case – the top in my installation.

Also, before installing the pump assembly, I went ahead and connected the fans to the fan hub (Centered in picture), just so I didn’t have to worry about anything being in the way.  This habit sort of stems from installing those massive air coolers, which you absolutely must do it beforehand!

Now we’re ready to install the pump assembly.  I typically prefer having four mounting screws for a guaranteed even installation and paste disbursement, but for this design they chose two screws.  This does make things easy and should still provide adequate pressure across the entire processor.

Deepcool Captain 240 EX - Completely Installed

Overall, installation took me maybe 15 minutes tops, and that’s inclusive of attaching the fans to the radiator all the way to securing the block.

Lastly, firing it up, we get a chance to see the red LED over the reactor-style shroud and it looks pretty neat.  This only pulses and there is no way to make it steady that I have discovered.  Nevertheless, it does help draw attention to the block even more for you windowed case users.

Deepcool Captain 240 EX - Running

While I don’t have a sound meter to test the loudness of the cooler, at idle you absolutely cannot hear the pump or fans from 3-4 feet away, and under full load, it’s hardly disturbing and nice and quiet yet.  It’s not the kind of quiet that you won’t have to nudge your volume up a bit, but it’s a quiet that you don’t have to shout at someone while speaking with them.

Since we know that everyone is curious with how well the Captain 240 EX performs, let’s move onto the testing.  We’ll compare it to the various air and liquid CPU coolers that we’ve tested in the past, see how well it works with an overclock to 4.3GHz on an i7-4770k.  Before we get into the tests, click the next page to see what we’ve got in our system.

    I got the Maelstrom 120K, a passable product when it worked, but had serious reliability issues. First the fan went, then the pump. I had nothing but aggravation trying to get DeepCool to honour their warranty, which they never did. See below for how many hoops they made me jump through and all the emails back and forth. I won’t ever buy from them again.

    Hello Vivy,
    I still have not received a refund or replacement. I already sent pics twice of the original box with serial number and all parts in and out of my PC. As for the detailed reason of the broken cooler, it is because it is unreliable, sometimes it works fine and other times it stops and my PC overheats. Anyways, if I don’t receive a refund this time, I’m just going walk away and forget about Deepcool. I’ll and buy something else, and post this entire email online so the public can see how you handle your warranty.
    Kind regards,
    Michael Benyacar

    Hello Vivy,
    Thank you for you offer of a replacement fan. After checking out the specs of theTF-120 fan, I noticed it is 26mm thick.
    The HTC case I am using can only fit a 15mm to 20mm thick fan. It is the reason I chose your cooler in the first place.
    Do you have something that is quieter and will fit?

    Hello Vivy Zhang,
    Thank you for your quick response. Regarding the noise, it is coming from the 120mm fan that is attached to the little radiator.
    When I first installed the cooler the noise was acceptable. However, over time the fan has become noisy and distracting. The pump noise quiet and is acceptable. Since the computer is being used in a recording studio environment, a quiet PC is important.
