Deepcool, founded in 1996 Beijing, is a Chinese manufacturer of computer components like PC Chassis, CPU Coolers, Power supplies and more. This might be a new name for you if you’re only familiar with the brands available locally. But Deepcool has a huge presence in the global market with about 200 products in their arsenal. 50 of which are under their brand Gamer Storm which is dedicated to the high-end line of their products. And thanks to our friends over at Deepcool, we’ll be looking at one of their most exciting product available in the market currently, the Deepcool Castle 240 RGB CPU Cooler.

The Deepcool Castle 240 RGB is a 240mm RGB All-in-One Liquid CPU Cooler that not only supports the common Intel and AMD CPU sockets, but it also supports the giant of a TR4 Processors (Threadripper) that was launched back in 2018. The radiator in this pack is made out of aluminum and can hold up to 2x 120mm fans. And you don’t have to worry about the fans as it already comes with 2 addressable RGB Hydro Bearing fans that have a rated fan speed of 1800-+10% RPM and Airflow of 69.34CFM. The tubes on this cooler like any in the current days are sleeved. And the most attracting feature of this cooler is the CPU Block.

The CPU block of Castle 240 RGB has a circular shape with a reflective top. However, that’s just an illusion. Beneath that surface, we have address RGB LEDs implemented along with the GamerStorm logo in the middle which looks like it’s floating once the system is turned on. And combined with the addressable RGB LED fans installed on the radiator at top of the chassis, damn does this create an awe-inspiring view.

Here’s what the manufacturer has to say about the Deepcool Castle 240 RGB.

DEEPCOOL, the company that specializes in water-cooled and illuminated cases for the PC enthusiast has just introduced a brand new AIO liquid cooler- CASTLE 240RGB, suitable for Intel and AMD based systems. Its featured built-in double window panes and 16.7M true color lighting system provide a perfect display of aesthetic illumination. Its ultra-large, pure copper CPU block and its optimized E-shaped micro water channel designed to enlarge heat contact areas and effectively enhance heat circulation efficiency meet users’ needs for high performance and aesthetics

So without any further ado, let’s dive deeper into the review with the unboxing of the product on the next page.

Deepcool Castle 240 RGB Unboxing

So I actually did an unboxing video for the Deepcool Captain 240 RGB CPU cooler where I go through everything that you get with the cooler. But if you’re more into the picture content, then I’ve covered everything below as well.

So you get the cooler in a rectangular black box with a green strip at the bottom that says 240MM Water/Liquid Cooler. In the center, we have the main system or the CPU Block glowing in the RGB goodness. And we can see that the Gamerstorm logo is also present in the center of the cooler. Yes, the box is a little bit torn up, but yes, the cooler did survive the journey, so kudos to the packing!.

From the back, you can see what a rough journey the Cooler had. But I’m glad that it survived all that. So at the back of the box, you’ve some detailed specification and features mentioned. We also a diagram of the radiator and 2 diagrams of the CPU Block along with their dimensions. And at the bottom, we have the supported CPU sockets listed, and yes, the Castle 240 RGB does support TR4 processors as well.

At one side of the box, we have the product name mentioned in the center and some features mentioned at the bottom like addressable RGB, Powerful Moter, Ceramic Bearing, Cooper Base, Microchannel, and Easy Installation.

And on the other side, we once again have the model name mentioned in the center, but this time at the bottom we have a picture of the whole cooler with RGB LEDs on.

Let’s not leave any stone unturned. At the bottom of the box, you’ll again find the Cooler name mentioned along with some 4 features mentioned that are +5Volt addressable RGB LED, RGB Sync, RGB controller and supported sockets.

So, when you open up the box, you’re greeted with something like this. Everything’s well protected and have proper molds for their size so that they don’t move here and there during the shipping.

So that is all the stuff that you get along with the Deepcool Castle 240 RGB All-in-One Liquid CPU Cooler other than the fans. You’ll find them hidden in a white cardboard box. Now let’s have a closer look at each component in our closer look tab.

Deepcool Castle 240 RGB Closer Look

So here’s the installation kit for the Intel CPUs. You only get the mounting bracket and 4 double-sided screws.

And this is what the installation kit for AMD CPUs look like. Also with 2 mounting bracket and 4 double-sided screws.

However, for TR4 CPUs, you’ll be needing the 4 double sided screws provided in the little bag tagged with TR4. As for the mounting bracket, you’ll be using the same ones present in the previous picture.

As for the baseplate, we’re using a universal backplate. You just got to flip the sides for either platform. Each side is tagged with their respective platform.

Then we have some essential stuff for the installation of both platforms like 2 different type of nut sets, 4 screw bolts that go into the backplate, 4 insulative cushion that holds the screw bolts inserted into the backplate in position. And then we also get a small tube of Deepcool’s own thermal grease.

For the radiator and fan mounting, we get 8 screws and bolt for each purpose.

As for RGB extension and manipulation, we get about 4 cables. Let’s go through them one by one.

First, we have two different kinds of Addressable RGB extension cables. 1 is a three pin cable and one is a 4 pin cable. So they’ve got different types of motherboards covered.

Then we have the remote controller for the RGB LEDs. On one end we have a SATA connector that powers up the whole RGB LEDs and then in the middle, we have the remote with 3 buttons, and on the other end, we have a three pin connector.

And then finally, we have another extension cable which on which we have one 3-pin female and four 3-pin male connectors.

The Deepcool Castle 240 RGB is shipped with 2x DF120 120mm fans. The fan has a black glossy body with 9 translucent blades. And on each corner, we also have rubber paddings to reduce the vibration produced by the fans. And you can also find some microchannels on the corner of the body. I’m not sure what the purpose of these microchannels would be, or if they’re just for aesthetic purpose there, but if it’s just for the aesthetic purpose, then they’ve done it right. The fan looks amazing up close but also keeps you a bit hesitant from touching them as they have a glossy body.

You can’t find these fans listed on Deepcool’s website as I believe they are made specifically for this cooler. However, the closest match available on their website is the RF120 fan which shares a similar body design but there’s a big difference in their performance. These fans are rated for 1800+-10% RPM with a fan airflow of 69.34CFM (Cubit Feet per Minute) and air pressure of 2.42mmH2O. These are Hydro Bearing fans rated at 17.8-30dB(A) noise level and requires 12v to run at their full speed.

As for connectivity purpose, we have 2 cables coming out of the fan. One is a 4 pin PWM cable that goes to the fan hub or on your motherboard directly. And the other is a 3 pin addressable RGB cable that goes to the remote.

We also get some accessories for the fans as well. So we have 1x fan hub, 1x extension cable for the hub, 1 zip ties, and 1 double-sided tape. The hub isn’t like what you regularly see in the market, with a rectangular design. Rather it has a triangular design, support for 4 fans, and has the GamerStorm text embedded on the body.

And this is what the Castle 240 RGB looks like without the fans installed.

The Castle 240 RGB is using an aluminum 240mm radiator. In dimension, it is 274mm in length, 120mm in width and 27mm in height. And with the fans installed, it will be 52mm in height. Just like Deepcool’s Captain 240EX RGB, the Castle 240 RGB radiator has a refill port, but with the warranty voided sticker glued to it.

Coming down to the heart of it all, the pump/CPU Block. The pump is 91x79x71mm in dimensions. Most Intel and AMD processors fall under 40mm in dimension, whereas the TR4 has a dimension of 58.5mm by 75.4mm. So not even there’s ample room to cover both the Intel and AMD processors, but the TR4 processor completely as well.

As for the pump design, It has a greyish matte body finish. We have a mirror-like the design on the top like you can actually see your reflection on it clearly, but there’s secret to it. The top features RGB LEDs within. And there’s also the GamerStorm logo present at the bottom which you cannot see without the LEDs glowing. Other than that, there’s not much going about the pump.

On the bottom, we have a protection sticker applied to the copper base. It’s good to see that Deepcool has gone with a white sticker instead of transparent, as I’ve seen a couple stories on the internet of people forgetting to remove the sticker from the baseplate.

Deepcool Castle 240 RGB Installation

Now that we’ve gone through everything about the CPU Cooler, let’s take a look at the installation processor. I’ll be going through the Intel platform installation process as I don’t have the AMD platform at hand with me right now. And in Intel, I’ll be going with the installation steps for LGA 1151 processor.

First, grab the backplate and insert the 4 screw bolts into the holes at the rear end while the Intel embedded on the backplate is facing you. Make sure it’s at the holes at the rear end as those are for the LGA115x series socket, the front ones are for LGA1366 socket CPUs.

Then go ahead and insert the insulative cushion on each corner of the backplate. This will hold the screw bolts in place.

Then go ahead and grab the Intel mounting bracket and screw it onto the pump with the 4 nuts provided with it.

Now that your pump and backplate is ready, Install the fans on the radiator with the 8 bolts provided.

For the next steps, you can go in any order you see fit. As for me, I first like to mount the radiator to the chassis and then install the pump onto the CPU cooler. But some might like to go the other way around. But anyway, you’re provided with the 8 screws to mount the radiator to the chassis. And I’ve mounted the Radiator on the top.

Now that we have everything prepared, all we need to do is install it onto the CPU. But before that, don’t forget to apply a little bit of the Thermal Grease onto the CPU. Once that’s done, insert the backplate from the back of the motherboard into the 4 holes you’ll see around the CPU socket area.

Now that everything is in position, just align the mounting brackets installed to the pump over the screw bolts on the backplate, and tighten it up with the 4 Nuts. And that is about it for the installation part. Now all that’s left is the cables, RGB LEDs and fan hub installation. You can go about any way you see fit with them.

Testing Methodology:

The Deepcool Castle 240 RGB comes with its own thermal grease. To keep a standard across other CPU coolers for cross reference, we tested the cooler with both the grease it comes with and Noctua NT-H1 thermal paste.

The chassis used for the test bench is Thermaltake View 31 TG. During the test, all fans were running at 100% speed as well as the pump. As for fans other than the two on the radiator, we have one Thermaltake Ring 12 fan as an exhaust and 3x Deepcool MF120 RGB fans on the front as intake. We didn’t opt for open-air test bench as most users at home usually don’t have such kind of setups.

We took 4 readings in our thermal test, idle at stock, load at stock, idle at overclocking and load at overclocked settings for CPU. At stock, we used a manual Vcore volt of 1.2. And our overclocked CPU at 4.7GHz required 1.27vcore. So there’s a big difference in the voltage.

The readings were noted via the HWiNFO64. The idle readings were taken after 10 minutes of leaving the computer as is. While the readings at load were taken after putting 15 minutes of stress on the CPU via Aida64 Extreme stress test on everything other than HDDs. The readings mentioned in the charts are the average of all 6 cores.

Deepcool Castle 240 RGB Thermal Performance

So starting from the thermal performance at stock settings with the system on idle, we can see that the Deepcool Castle 240 only points away from taking the throne from the Thermaltake Water 3.0 Ultimate. There’s no difference in the performance when it comes to the different thermal paste used, however. But when we put the system on load, the Deepcool Castle easily takes away the crown from the Thermaltake Water 3.0 Ultimate.

We can even see that performance gap is even wider when it comes to the Castle compared to the pre-applied grease provided with the Deepcool Captain. Whereas we only saw a 1C difference in the Deepcool Captain 240EX RGB with different thermal grease, there’s about 2.5C difference in the thermal grace provided with the Deepcool Castle when compared with the Noctua NT-H1. So, you don’t really need to look for aftermarket thermal grease when it comes to Deepcool Castle 240 RGB.

So, you don’t really need to look for aftermarket thermal grease when it comes to Deepcool Castle 240 RGB.

And when it comes to the cooler’s performance at overclocked settings, we’re sitting at about 39.16C, which is lowest in the chart at idle. And once we pressed the stress button on the system, we were sitting at about 81.5C temperature on load after 15 minutes. This is some promising results from the Castle as it gives us a little bit more headroom for trying for a higher overclock within safe limits. Compared to the performance at load on the stock setting, we are sitting at a difference of only 14.8 degree Celsius. So other than the RGB goodness, this coolers packs a real punch as well when it comes to cooling.

Deepcool Castle 240 RGB Acoustic Performance

As for acoustic performance, my home isn’t the best place for this type of test so I keep the numbers out of it so far. As for a general idea, you can’t hear much of the cooler when you have a room fan running over your head. Other than that, you won’t be hearing much of it any ways when the fans are spinning slow. But once they hit their full speed, you can hear the constant hissing sound produced when the blades are cutting through the air. However it’s not as loud that you’d start scratching your head. So not much to complain about the acoustic performance of the Deepcool Castle 240 RGB AIO CPU Cooler.

Deepcool Castle 240 RGB Effects

So I’ve created a RGB effects video for the CPU Cooler utilizing all the RGB goodness that was available in my chassis. The effects in this video are presets that are available through the remote that’s shipped with the cooler. Only thing that sucks is that the remote is a wired one and needs to be attached to the chassis. A wireless remote would have made life much more easier for those who do not have motherboard that supports Sync All feature. As for the results, I’ll let the video do that talking.


The Deepcool Castle has many things to offer with a very attractive price tag. For $130, you’re getting TR4 CPU support along with the other common chipsets, you’re also getting addressable RGB LEDs embedded into the CPU block and fans, and you’re also getting very good thermal performance out of it.

The Captain 240 RGB has an oddly attractive design as it looks a little bit too big for its own good. And the color scheme (Grey) picked also doesn’t blend with many systems. But once the RGB LEDs are enabled on the top of it and inside the system, that odd attractiveness converts into a satisfying view. The GamerStorm logo in the middle of a black plate gives a floating impression which will pause you on your first glance for sure.

And the RGB effects on the block and fans is also very fluid. I wasn’t able to use the Asus Aura Sync feature with this cooler as I have a gigabyte motherboard, but the cooler also comes with a remote which lets you toggle through a number of predefined colors and effects. And the transition from one effect to another only takes milliseconds. However, synchronizing the effects on the cooler is difficult so you’re either good with the ASUS AuraSync compatible motherboard or the stationary color effects. Or you could just go with any combination that sooth your eyes. Not that the system doesn’t look awesome with a single color theme throughout.

And the charts speak for themselves when we talk about thermal performance. The Deepcool Castle 240 RGB stands as the clear victor when it comes to the thermal performance in our testing. At 29C ambient room temperature, the Castle was able to keep the cooler under 36C at stock speed. That’s a delta of only 6C. And once we threw everything at it, it was still able to keep the CPU under 82C, and that with the TIM that’s supplied with it. So when you’re not stress testing your CPU and just watching videos or playing video games, you can rest assured that your CPU is not going anywhere near the thermal throttling limit (well yea it also depends on your overclock settings).

At the time of review, I wasn’t able to find any listing of the CPU cooler in the US, however, on Amazon UK, the Deepcool Castle 240 RGB is being sold for 99.99 pounds. This equals to about 130$ or Rs. 18500. Giving a search through Amazon or Newegg or our local market, we can see that the TR4 supported CPU coolers also go for around the same price tag. So in terms of pricing, we’re doing good.

If there was anything that I’d change about this CPU cooler, then it would be the greyish color they went with the CPU block. Maybe having multiple covers for this would have helped. But then again, in the end, once the system is turned on with all the RGB LEDs enabled, that color wouldn’t really matter. And the other thing would the the RGB remote control. Since it’s wired and needs to be attached to a Sata connector and RGB leds, it very much limits the option of utilization. Like I had the remote hanging from the bottom on the front to access it, cause if I left it in the chassis, it wouldn’t be very accessible. All this wouldn’t have been an issue had I had a motherboard with aRGB port or the remove was wireless.

So all and all, I’ve had great pleasure testing the Deepcool Castle 240 RGB AIO CPU Cooler. If you have a weird imagination as mine, you’ll be able to imagine a face as well like me when you look at the CPU blocks and the fans on the radiator. But yea, overall, the RGB effects and the performance and the installation, it was a nice experience and will be worth your hard earned money. Coming down to the conclusion, I would like to give the Deepcool Castle 240 RGB our precious Recommended Buy award!
