An LGA4189 liquid cooler is a copper water block and pump-and-radiator loop that cools Intel Xeon processors in the LGA4189 socket where air coolers run out of headroom; ToneCooling offers 1U and 2U LGA4189 server liquid coolers rated for 500 W CPU TDP. Use them for high-TDP processors, dense racks or noise-limited servers.
Which LGA4189 Liquid Cooler Fits Your Server?
| Product | Server height | Configuration | Rated CPU TDP |
|---|---|---|---|
| 1U LGA4189 CPU liquid cooler | 1U | Copper block, single CPU | 500 W |
| 2U LGA4189 server liquid cooler | 2U | 2-way kit (dual CPU) | 500 W |
Rated TDP as listed on each product page; actual performance depends on radiator airflow, inlet air temperature and installation.
When Should an LGA4189 Server Use Liquid Cooling Instead of Air?
Choose liquid cooling when the processor TDP is above what a 1U or 2U air cooler is rated for, when several high-TDP servers share a dense rack, or when fan noise must stay low. The water block takes heat directly off the CPU and moves it to a radiator, so the CPU runs cooler at the same airflow. For lower loads, an LGA4189 air cooler is simpler and cheaper.
What About Rack-Level Liquid Cooling?
For racks connected to a facility loop and CDU, a direct-to-chip cold plate replaces the self-contained cooler. See our server CPU liquid cold plates and the liquid cold plates overview.

LGA4189 Liquid Cooler FAQ
What TDP are the LGA4189 liquid coolers rated for?
Both the 1U and the 2U LGA4189 liquid coolers are listed for 500 W CPU TDP.
What is the 2-way LGA4189 kit?
It is a 2U liquid cooling kit that cools two LGA4189 processors in a dual-socket server from one loop.
Is a liquid cooler better than an air cooler for LGA4189?
For high-TDP processors, dense racks or low-noise requirements, yes; for moderate TDP, an air cooler is simpler and costs less.
Can ToneCooling customize the cooler?
Yes. Block, tubing, radiator size and mounting can be adapted to your chassis as a custom design.
