Installing the Thermaltake Water 3.0 240 CPU Cooler

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!
