Closer Look

Let’s check out the ALPHACOOL Core Ocean AiO. It’s an affordable CPU water cooler with a great price-performance ratio. Unlike the Eisbaer CPU AiO, it’s not expandable, but ALPHACOOL ensures it offers a durable and low-maintenance solution for water cooling common AMD and Intel sockets.

Radiator

ALPHACOOL provides a 397x120x38mm aluminum radiator for the Core Ocean AiO. Unlike most AIOs with 27mm thickness, this radiator’s 38mm offers more surface area for improved heat dissipation. When combined with a standard 25mm thick 120mm fan, the total height reaches approximately 64mm, including a 1mm allowance for screw heads.

The Core Ocean AiO rocks a cool black fin stack with 19 fins per inch, giving it a sleek look. The rectangular design, 12 coolant channels, and 105mm hole spacing make it user-friendly. Plus, the aluminum housing is black-coated, showing off a classy ALPHACOOL logo. Don’t sweat the 38mm thickness – it’s just the standard fin stack design.

Similar to other popular AIOs, this unit boasts soft tubing connected through barbed fittings on the radiator, cleverly concealed by two black covers. A sticker, likely with the unit’s serial number, is also in the mix.

The right picture highlights two design points. First, ALPHACOOL’s meticulous work on the fins showcases a clean finish. Second, there’s no protective plating under the mounting holes. This plate typically shields screws from harming fins and coolant channels. It’s advised to stick to the screws provided with the unit.

The soft tubing has a length of approximately 400mm. They are made of FEP and have a nice weaver cover that gives aesthetics to these tubings. These tubes are somewhat flexible and don’t kink, which is a good design.

Pump/Block

It is time to take a look at the block and pump of this unit.

I’m really digging the pump housing design from ALPHACOOL! It’s this slick, compact thing at 70.2×70.2x46mm – seriously low-profile. Crafted from ABS and POC material, the matte black finish adds a classy touch. 

A white diffuser in the angular corner hints at the presence of digital RGB LEDs beneath, creating a vibrant effect along the entire length of the housing, cleverly sandwiched between the top cover and the lower part of the pump’s housing.

Looking at the backside of the housing, I noticed the soft tubes are set at a smart 90° angle. It’s cool because you can rotate them to the left or right as needed. Two cables come out from above the tube slotting.

There is a warranty void seal over this port. This clearly indicates that this port is reserved for factory use only, and removing this seal would end the warranty, so don’t attempt this.

In the side view, there’s no branding, but notice the inset between the housing and the base top. That’s where the mounting brackets slide in. This cooler has a unique mounting mechanism, a bit different from what we’re used to.

The diffuser comes in a sleek single-piece design with a nice angular bend.

ALPHACOOL opts for a 4-pin PWM connector to power and control the pump speed, setting it apart from the majority of AIOs using a 3-pin DC-based control. The digital RGB connectors are labeled as JST, but they’re actually standard 3-pin, 5V connectors for powering digital RGB LEDs. 

This cooler has a large size copper base. There is a protective cover over the base, cautioning the user to remove it before installation. This cover is there to protect the base from any damage. ALPHACOOL has mentioned the fin structure of the base plate to be 0.1×0.1mm.

Fans

ALPHACOOL has provided 3x 120mm fans with this cooler. These are new Core series fans. They are, again, a no-frill design with an emphasis on performance. Fans’ housing is in black color. Each fan has 9x blades.

No anti-vibration pads, no center branding, and no RGB – just pure performance. Flip them, and you’ll see a 4-arms setup with efficient wire routing. These fans hit up to 2500 RPM, drawing 0.43A at 12VDC, and offer generous blade-to-frame clearance.

There is a black color flat cable with a 4-pin PWM header coming out of the fan to power the motor of this fan.

These fans come with Auto Stop and Auto Restart functions, requiring a motherboard that supports these features. They also report the tachometer.

Accessories

Now that we have taken a look at the core components of this cooling unit, it is time to check out the accessories given in the box.

There is a pictorial illustrative manual guiding the user on how to install this cooler. The main hardware is supplied inside a black color bag with a transparent front. Supportive elements are provided in a separate pouch.

The left picture shows the hardware for AMD brackets. These include:

• 1x Set of AMD Bracket for AM4/AM5
• 4x 2mm washers
• 4x Longs Screws or Pillars
• 1x User Guidance Page for installation

Taking a look at the Intel platform, we got:

• 1x Plastic made backplate
• 1x set of Mounting Bracket
• 4x Long Screws or Pillars for Intel LGA20xx Socket
• 4x Long Screws or Pillars for Intel other sockets
• 1x User Guidance Page for Intel LGA20xx mounting

ALPHACOOL has provided:

• 1x Syringe of Thermal Paste
• 12x Long Screws for Fans Mounting on the Radiator
• 12x Short Screws for Radiator Mounting
• 3-Way PWM Splitter Cable with 4-pin PWM Connector

We mentioned above that this cooler uses a different mounting mechanism. The last pieces of the puzzle include:

• 4x Springs
• 4x 0.5mm Washers
• 4x Nuts

Installation

We have tested this cooler on an Intel LGA1700 socket using GIGABYTE Z790 AORUS ELITE AX and Intel Core i7-13700K. We have also used this cooler on the AMD AM5 platform using GIGABYTE X670E AORUS MASTER and Ryzen 7 7700X. We will report test results from Intel.

Here’s a quick rundown for installing on an Intel LGA1700 socket:

1. Attach the mounting brackets to the block.
2. Use Long Screws, 2.0mm washers, springs, and nuts to secure the assembly on each mounting corner.
3. Peel off the protective cover from the block’s base.
4. Apply the thermal paste on the CPU IHS.
5. Position the block on the CPU, aligning the screw tips with the back plate’s standoffs.
6. Place the back plate on the backside of the motherboard.

Follow these steps for installing the cooler on AM4 and AM5 sockets:

1. Use an AMD stock backplate for compatibility with the AM5 socket.
2. For AM5, use both washers (0.5mm from the Intel packet and 2.0mm from the AMD packet).

Clearance

The ALPHACOOL CORE OCEAN T38 CPU AIO 360mm is a liquid cooler. It has slim tubing, which doesn’t obstruct DIMM slots. Similarly, there is no clearance issue for the first x16 PCIe slot. The radiator has a dimension of 397x120x38mm size. Keep that in mind when it comes to PC Case clearance.

Digital RGB

My ALPHACOOL CORE OCEAN T38 CPU AIO 360mm rocks digital RGB lighting on the pump’s housing. I’ve got standard 3-pin, 5V connectors, and I tested it on GIGABYTE motherboards, specifically the AM5 platform. Controlling the lighting with RGB FUSION 2.0 was smooth – check out these cool pics!

Thermals

Let’s see the result graph:

No other coolers in the graph because we only had time to test a few units for comparison. The cooler did great, keeping temps under 80°C with a heavy multi-core load. This bodes well for actual gameplay thermals being even lower.

Noise

The fans provided with ALPHACOOL CORE OCEAN T38 CPU AIO 360mm are rather very loud at full speed. We measured roughly 59~60 dB(A) at an ambient sound level of 32~33 dB(A).

Pro Tip: To mitigate the noise issue, set a custom fan curve through your motherboard’s BIOS or dedicated software. Adjusting the PWM duty cycle can provide a balance between cooling performance and noise levels.

Should You Buy It?

After a thorough examination of the ALPHACOOL CORE OCEAN T38 CPU AIO 360mm, here’s my recommendation:

Buy It If:

✅Budget-Friendly High-Performance Cooling: The ALPHACOOL CORE OCEAN T38 is an excellent choice if you’re in search of an affordable 360mm AIO liquid cooler that delivers robust thermal performance.

✅Sleek and Neutral Design: For enthusiasts who prioritize a clean and neutral aesthetic without the extravagance of RGB fans, the ALPHACOOL CORE OCEAN T38’s black fans and subtle RGB lighting on the pump’s housing make it a fitting option for stealth or neutral-themed builds.

✅Reliable Cooling Solution: If you place a premium on reliability in your cooling solution, the ALPHACOOL CORE OCEAN T38 offers a durable and low-maintenance option for water cooling common AMD and Intel sockets.

Don’t Buy It If:

❌Silent Operation is Essential: If you demand a near-silent cooling solution, the ALPHACOOL CORE OCEAN T38 might not be the ideal choice, as the provided fans and pump can be quite loud, measuring around 59-60 dB(A) at full speed.

❌RGB Lighting Customization is a Priority: For users who desire extensive RGB lighting customization options, the ALPHACOOL CORE OCEAN T38 falls short as it features subtle RGB lighting only on the pump’s housing.

Conclusion

In conclusion, my experience with the ALPHACOOL CORE OCEAN T38 CPU AIO 360mm was quite insightful. The thicker radiator and high FPI count indeed contribute to effective heat dissipation, making it a promising choice for users looking for performance-oriented cooling solutions.

However, the noise level from both the fans and pump is a significant drawback. The fans, despite their impressive specs, produce a loud noise, which might disrupt the overall experience. The sleek and stylish design of the pump housing, though, adds a touch of elegance to the build.

While the noise factor could be a deal-breaker for some users, with a 3-year warranty and good thermal performance, the ALPHACOOL CORE OCEAN T38 presents a compelling option for those prioritizing performance. Consider adjusting the fan settings for a quieter operation, and you’ll have a solid cooling solution for your system.
