CPU Liquid Cooler
Description
Looking for the best CPU liquid cooler that performs? EKWB AIO coolers are the answer for serious Computer Parts buyers in Bangladesh. At PCB Store, we stock the full range of EKWB liquid coolers — from budget-friendly non-RGB models to premium D-RGB and Nucleus series AIOs. Whether you are building a gaming rig, a content creation workstation, or a high-performance custom PC, EKWB delivers world-class cooling engineered for real results.
EKWB coolers are the best CPU liquid cooler choice for precision. Pump and radiator work together to maintain stable CPU temperatures during heavy workloads. For gamers and creators in Bangladesh, this stability means smoother overall performance.
Style matters in modern PC builds. EKWB coolers feature ARGB lighting that syncs with your motherboard for gaming. This adds personality to your setup while keeping temperatures low.
Cooling efficiency depends on airflow. EKWB uses EK-Vardar fans, known for durability and performance. These fans push air through the radiator with precision.
Investing in EKWB means long-term reliability. These coolers are built with premium materials. At PCB Store, we provide warranty support for peace of mind.
We carry every major EKWB AIO series. Each model is built for a different budget and use case. Here is a quick overview of what is available.
The EK-AIO Basic is EKWB's price-conscious, no-nonsense AIO. It has no RGB lighting. But it cools extremely well.
It comes in two radiator sizes:
Both models include:
This series is perfect for builders who want a high-performance cooling solution without the RGB tax. It is one of our top picks as a computer part for clean, minimal builds.
The D-RGB series adds fully addressable RGB lighting. Both the CPU block and fans glow.
Available sizes:
The D-RGB lighting syncs with all major motherboards for gaming — including ASUS Aura Sync, MSI Mystic Light, and Gigabyte RGB Fusion. The CPU block features a frosted acrylic cover that diffuses light smoothly.
The EK-AIO D-RGB series is the most popular mid-range liquid cooling option we sell at PCB Store. It suits gamers who want both performance and aesthetics.
The Elite series is built for power users. These are the right choice for overclocked CPUs and high-TDP processors.
Models in this tier:
Key upgrades over the standard D-RGB series:
If you build a PCB Featured PC for gaming or professional content creation, this tier is where serious performance begins.
The Nucleus series is EKWB's newest and most advanced AIO lineup. It won the iF Design Award. It tops performance charts worldwide.
Nucleus models available:
The Nucleus series features:
This is the AIO we recommend for anyone building a custom PC at the highest performance level. If you want the CPU liquid cooler available in Bangladesh, the Nucleus CR360 is it.
Specs matter. But they can be confusing. Here is what the key specifications actually mean for real-world use.
EK-Vardar S fans spin between 550 RPM and 2200 RPM. At 550 RPM, they are nearly silent. At 2200 RPM, they push maximum airflow.
Your motherboard's PWM (Pulse Width Modulation) header controls this automatically. The fans spin fast only when the CPU temperature rises. At idle, they stay slow and quiet.
The EK-Vardar S fans move up to 77 CFM (cubic feet per minute). Higher CFM means more hot air exits the radiator faster. This is especially useful in Bangladesh's warm climate, where getting heat out of the case quickly matters.
Static pressure measures how effectively the fan pushes air through resistance, like radiator fins. The EK-Vardar S fans deliver 2.89 mm H2O of static pressure. This is optimized specifically for radiator use, not general case airflow.
At maximum speed, the EK-Vardar S fans produce 33.5 dBA. That is quieter than a normal conversation. At low speeds (550–800 RPM), they are nearly inaudible.
For long gaming sessions or late-night work sessions, this noise profile is genuinely comfortable.
Buying a liquid cooler is not just about brand. You need to match the cooler to your CPU, case, and use case. Here is our practical guide.
Radiator size is the most important decision. It directly affects cooling performance.
240mm radiator — good for:
360mm radiator — better for:
Always check your PC case specifications before buying. Confirm it has a front or top 360mm radiator mounting position.
Older EKWB AIO models (Basic and D-RGB series) support:
The newer EK-Nucleus AIO series adds full support for:
If you are building or upgrading with a modern CPU, the Nucleus series is the correct choice. It supports the latest sockets out of the box with no adapter required.
This is simple. Ask yourself one question: Does my build have a side panel window?
If yes, go with the D-RGB or Nucleus series. The lighting looks excellent through a glass panel.
If not, save money with the EK-AIO Basic series. You get identical cooling performance at a lower price. RGB adds no thermal benefit.
This is a step most buying guides ignore. Bangladesh is a tropical country. Room temperatures in summer regularly exceed 30°C to 36°C.
That ambient temperature directly impacts your cooler's performance. A 360mm AIO will maintain lower CPU temperatures in hot rooms compared to a 240mm model. If your PC room is not air-conditioned, we strongly recommend a 360mm radiator for any build running a high-performance processor.
EKWB Products are a long-term investment. The 5-year warranty on the Nucleus series means peace of mind for years. The pre-filled sealed loop requires zero maintenance.
No coolant top-ups. No refilling. No cleaning the loop. Just install and run.
At PCB Store, we also carry the EK-Vardar S replacement fans separately. If you ever need to upgrade or replace fans, you can do so without replacing the entire cooler.
PCB Store is your trusted destination for premium desktop components in Bangladesh. We understand what BD buyers need — genuine products, fair prices, and reliable support.
Here is what sets us apart:
We also stock compatible products alongside your cooler. Looking for the best budget motherboard that pairs with your new EKWB AIO? Our team recommends the right combo for your budget and goals.
