What’s New With LGA 1851?
While the mounting mechanism is largely identical to LGA 1700, we recommend choosing coolers officially certified for LGA 1851. Many manufacturers—such as Noctua, be quiet!, Arctic, and EK—have already updated their models or offer upgrade kits. This ensures ideal contact pressure, safe installation, and optimal cooling performance.
Which Cooler Suits Which CPU?
- Intel Core Ultra 5: Efficient and power-saving—great results with mid-range air coolers or compact AIOs (e.g., 240 mm).
- Intel Core Ultra 7: Best paired with powerful dual-tower air coolers or high-quality 280/360 mm AIO liquid coolers.
- Intel Core Ultra 9: Maximum turbo power – we clearly recommend a high-performance AIO liquid cooler for long-term stability and low temperatures.
Air or Liquid? You Decide
Whether you value maximum cooling performance, a compact footprint, or quiet operation, we've got the right solution for your setup. Use the filters to easily find your perfect LGA 1851-compatible cooler.
Frequently Asked Questions About CPU Coolers for LGA 1851
Can I still use my old LGA 1700 cooler?
Yes, often your LGA 1700 cooler will fit the new LGA 1851 socket. Intel has kept the mounting hole spacing the same, which means the physical fit is regularly not a problem. However, we strongly recommend checking whether your cooler’s manufacturer has officially confirmed LGA 1851 compatibility. Some brands offer updated mounting kits or revised backplates to ensure optimal pressure and thermal performance.
How much cooling power do I need for my Core Ultra 200 CPU?
That depends on the CPU model and how hard you push it. For Intel Core Ultra 5 processors, a good mid-range air cooler or compact AIO is typically enough. If you're going with an Ultra 7 or Ultra 9 CPU and plan to game or render at high loads, you’ll want a cooler that can handle 200 to 250 watts or more – ideally a dual-tower air cooler or a 280/360 mm AIO liquid cooler. Proper cooling helps your CPU stay fast and quiet under load.
Should I choose an air cooler or an AIO?
Both options work well and have their advantages. Air coolers are simple, reliable, and usually quieter when your system is idle. AIO liquid coolers shine under heavy load and often offer better cooling performance in turbo scenarios. If you prefer clean aesthetics and don’t mind a bit more installation effort, an AIO is a great choice. For silent builds or compact setups, a well-designed air cooler might be the better option. It really depends on your case, your CPU, and your priorities.
Do I need to buy thermal paste separately?
Most coolers come with thermal paste pre-applied or include a small tube in the box. That’s typically enough to get started. But if you're an enthusiast looking for maximum performance, it’s worth investing in high-quality paste or pads. Products like Thermal Grizzly Duronaut deliver excellent thermal conductivity and can help shave off a few degrees under load. Just make sure to apply it properly during installation.
