In this detailed guide, we walk through the full installation of the Thermaltake Water 3.0 240 AIO liquid CPU cooler. We’ll show you how to remove an old Enermax cooler, install the new unit on an Intel LGA 2011 socket, connect RGB and fan controllers, and optimize cable management. This cooler is perfect for mid to full-size cases and delivers excellent performance with minimal noise.

Thermaltake Water 3.0 CPU Cooler Installation Guide

Thermaltake Water 3.0 Setup: Key Steps and Tips

Installation Process
  1. Power off and unplug the PC. Remove front and side panels.
  2. Take out the old CPU cooler (in this case, an Enermax model), including the radiator and its bracket.
  3. Install the new radiator in the front panel using 8 screws and washers (don’t forget the washers!).
  4. Attach both fans to the radiator with provided screws. Use the foam gasket holes to reduce vibration noise.
  5. Mount the Intel bracket on the CPU cooler. Avoid touching the pre-applied thermal paste.
  6. Install standoffs and position the cooler onto the socket using four screws.
  7. Connect fan and RGB wires using the daisy-chain method and plug into the motherboard and PSU.
  8. Optional: Replace noisy fans with LED-equipped ones for added style and airflow.
Additional Notes

This cooler provides efficient performance, quiet fans, and clean RGB implementation, making it a great upgrade for any LGA 2011 build. With its all-in-one design and easy install, it’s beginner-friendly and powerful enough for most users.

What’s up, guys! In today’s episode, we’re replacing an old Enermax CPU cooler with the Thermaltake Water 3.0 240 all-in-one liquid cooler. The Enermax fans were getting noisy after two years, so it's time for an upgrade.

Before buying a CPU cooler, ensure the hoses are long enough to reach the CPU from the front panel radiator position. This is especially important for mid and full-sized cases. Our requirements included hose length, a dual-fan radiator, low maintenance (self-contained), LGA 2011 compatibility, and a budget under $130. The Thermaltake Water 3.0 checks all the boxes.

The kit includes two fans, radiator, screws, Intel/AMD mounting brackets, and a controller. For our Intel LGA 2011 socket, we start by orienting the bracket upright, so the branding is level. The hose connection is rotatable, which makes installation flexible—if it were fixed, this wouldn’t work in our case.

Snap the Intel bracket onto the CPU cooler, being careful not to touch the thermal paste. Next, attach the fans to the radiator, adjusting orientation so the RGB wires stay out of the way. Secure with eight screws. The mounting holes include foam gaskets to reduce noise.

The RGB controller features three buttons: mode, color, and speed. Fan power cables are joined with a three-in-one splitter. RGB cables are daisy-chained to the controller, which connects to your PSU. Fan power goes to the motherboard header.

Start by shutting down and unplugging the computer. Remove the old cooler: take off the front and side panels, unscrew the radiator from the front, and detach the CPU cooler. Unplug RGB and fan headers. Take a photo if needed for reference.

Remove the old mounting bracket if needed. We reused the existing bracket to simplify installation. Install the new radiator using eight screws and washers. Screw in the standoffs to the LGA 2011 socket (short end into the board), then mount the CPU cooler. Tighten evenly but don’t overtighten.

Connect the fan cable to the CPU fan header, and route the RGB controller cable through the case. Mount the controller at the bottom for easy access and plug into the power supply.

We also swapped a non-working fan with a spare LED fan from our shop. Three new fans were installed—one in the rear and two on top for better airflow and aesthetics.

Reattach the front and side panels, plug in the PSU, and power on the PC. If everything’s connected correctly, the system will boot, and fans and RGB will function. Don’t forget to install the glass side panel last for full visibility of your build!

This install may look intimidating, but it’s straightforward with the right tools. And the RGB effects? They're awesome. Thanks for watching—if you liked the video, give it a thumbs up, share, and hit subscribe to support the channel!
