The Best CPU Coolers for Ryzen 7 9800X3D
Five liquid coolers compared, from the Frozen Notte 360 White to the Liquid Freezer III Pro 420, with the trade-offs of each named.
By The PC Journal editorial team
12 min read5 products evaluated
The Ryzen 7 9800X3D uses the AM5 socket, and a 280mm or larger liquid cooler spreads its heat over a bigger radiator. Every pick lists AM5 support and a radiator of 280mm or more, ordered by radiator size.
This is a research roundup, not a lab test: fan size, VRM fan and cabling come from each maker's published specs; a missing VRM fan is flagged, not filled in, and no figure here comes from our own testing.

Worth a Look5 of 5
ARCTIC Liquid Freezer III Pro 360 on Amazon (opens in a new tab)
The Liquid Freezer III Pro 360 is built around cooling rather than lighting: offset mounting over the CPU hotspot, a contact frame for Intel and a small fan for the board's power stages.
Best for
- Buyers who want P12 PRO fans.
Skip if
- Price-first buyers should look at the Frozen Notte 360 White, which cost less when we checked.
Why we like it
Its fan cables run inside the tube sleeve for a tidy build. Its integrated VRM fan cools the motherboard power stage, which a standard AIO leaves without airflow. The offset cold plate sits over the CPU hotspot rather than the centre of the heatspreader.
The fan cables run inside the tube sleeving, so only one cable reaches the motherboard. Check that your case offers 360mm radiator support at the front or top, and allow for the radiator's thickness plus fans above the motherboard's heatsinks. It supports both AM5 and Intel LGA1851. Its price falls between the 360L Core and the Liquid Freezer III Pro 420, based on our last check.
Key dimensions & specs
- Fan size: 120mm
- VRM fan: Yes
- Cabling: Fan cables routed inside the tube sleeving
- Sockets named: AM5, AM4, LGA1851, LGA1700
Pros
- Built-in fan that cools the motherboard's power stages
- Fan cables routed inside the tube sleeving

What to Look for in a CPU Cooler for Ryzen 7 9800X3D
Key buying criteria so you get the right fit the first time.
Features beyond the spec table
The Aqua Elite 360 V6 White: a fourth-generation pump head. The 360L Core: CryoFuze paste in the box. The Liquid Freezer III Pro 360: native offset mounting toward the CPU hotspot.
Budget
Price does little to separate these 5: the Frozen Notte 360 White through the Liquid Freezer III Pro 420 all landed in the $50 to $100 tier, which leaves features to decide it.
Match the pick to your priority
Buyers who want P14 PRO fans and can spend more than the Liquid Freezer III Pro 360 costs: the Liquid Freezer III Pro 420. Spending as little as possible, with the Aqua Elite 360 V6 White the next step up: the Frozen Notte 360 White.
Software is optional but useful
LCD screens and lighting usually need the maker's software. Pump and fan speeds can run from motherboard headers instead.
Match radiator size to the CPU
A 240mm radiator handles most gaming CPUs. 280mm and 360mm units give more headroom for 170W chips and let fans run slower.
