Six air coolers for the Ryzen 7 7800X3D, compared on heat pipes, fans, RAM clearance and AM5 support.
By Alex Morgan, PC Hardware Editor
12 min read6 products evaluated
The Ryzen 7 7800X3D is rated at 120W and draws less than that in most games. Its V-Cache makes it sensitive to heat, so steady cooling matters more than peak capacity.
We compared six air coolers on heat pipes, fans, RAM clearance and AM5 support, using the makers' specifications.

Our Picks
Best for the 7800X3D1 of 6
Thermalright Phantom Spirit 120 SE
The Phantom Spirit 120 SE puts seven heat pipes into a dual-tower design at a budget price.
Best for
- Most 7800X3D builds.
Skip if
- Skip it if price comes first: the Freezer 36 cost less when we checked.
Why we like it
Its 154mm height fits most mid-tower cases. Thermalright rates it for CPUs from 105W to 280W, and mounting kits cover AM4, AM5 and Intel up to LGA1851. On heat pipe count it ties with the Dark Rock Elite and the Phantom Spirit 120 Digital EVO at 7.
On fan size it ties with the Peerless Assassin 120 SE, the Phantom Spirit 120 Digital EVO and the Freezer 36 at 120mm. Check that your case offers at least 154mm of CPU cooler clearance before ordering. On price it sat third of 6, between the cheaper Peerless Assassin 120 SE and the pricier Phantom Spirit 120 Digital EVO, at the time of writing. The maker doesn't give its warranty; if that figure matters, the NH-D15 G2 offers 6-year.

Well-Rounded Choice2 of 6
Thermalright Peerless Assassin 120 SE
The Peerless Assassin 120 SE is the budget dual tower most builders start with.
Best for
- Buyers who want two fans included.
Skip if
- Skip it if price comes first: the Freezer 36 cost less when we checked.
Why we like it
It has six heat pipes and two 120mm fans. At 155mm tall it fits most mid-towers, and its six heat pipes and two PWM fans handle mainstream CPUs. It is one of the best-known budget dual towers.
On heat pipe count it sits mid-pack at 6: the NH-D15 G2 offers 8, and the Freezer 36 comes in at 4. On fan size it ties with the Phantom Spirit 120 SE, the Phantom Spirit 120 Digital EVO and the Freezer 36 at 120mm. You also get a 25.6dB(A) noise rating.
The maker names AM5 but not Intel LGA1851, so check the maker's site if you are building on Core Ultra. Its price falls between the Freezer 36 and the Phantom Spirit 120 SE, based on our last check.

Best Quiet Pick3 of 6
Noctua NH-D15 G2
The NH-D15 G2 is Noctua's current flagship air cooler with eight heat pipes and two 140mm fans.
Best for
- Near-silent builds.
Skip if
- Skip it if price comes first: the Freezer 36 cost less when we checked.
Why we like it
It is large and costly, and it carries a six-year warranty. Its fans have a speed offset for acoustic fine-tuning, and there is 20% more fin area than the original NH-D15. Nothing else here matches its 8 heat pipe count; the Phantom Spirit 120 SE comes closest at 7.
Its 140mm fan size is the largest here; the Dark Rock Elite comes next at 135mm. You also get an offset design whose recessed lower fins clear the top PCIe slot, 59mm RAM clearance with one fan fitted and NT-H2 paste in the box. It was the most expensive pick when we checked, so weigh what it adds over the Dark Rock Elite. Buyers who need a confirmed height should compare it with the Phantom Spirit 120 SE, which comes in at 154mm.

Its 135mm fan size ranks second of 6 here, behind the NH-D15 G2 (140mm) and ahead of the Freezer 36 (120mm). It also offers a Speed Switch for quiet or performance modes and a 25.8dB(A) maximum noise rating. When we checked, only the Phantom Spirit 120 Digital EVO and cheaper picks cost less, and the NH-D15 G2 cost more.

Cheapest Capable Pick6 of 6
ARCTIC Freezer 36
The Freezer 36 is a single tower with a push-pull fan pair at a very low price.
Best for
- Tight budgets.
Skip if
- Skip it if heat pipe count matters most to you; the NH-D15 G2 offers 8.
Why we like it
It includes a contact frame for Intel LGA1851 and LGA1700. Its four offset heat pipes run in a single tower with two fans in push-pull. The click-in fan mounts make fan swaps easy, and it takes most 120mm fans.
Its side-flow heatsink lets the rear fan pull air through the fins and out of the case, and ARCTIC backs it with a six-year warranty. Its pressure-optimised fans push air through four offset heat pipes, which suits high-end CPUs in a single tower. Its 4 heat pipe count is the lowest in this group; the NH-D15 G2 leads at 8.
It matches the Phantom Spirit 120 SE, the Peerless Assassin 120 SE and the Phantom Spirit 120 Digital EVO on fan size (120mm). It cost the least of the 6 picks at the time of writing, with the Peerless Assassin 120 SE the next step up.
Key specs
- Heat pipes
- 4
- Fan size
- 120mm
- Warranty
- 6-year
- Fans included
- 2
- Sockets named
- AM5, AM4, LGA1851, LGA1700
Pros
- 6-year warranty
- Two fans included
- Mounts on both AM5 and Intel LGA1851
- Push-pull single tower
Cons
- Heat pipe count trails the NH-D15 G2 (8)
- Fan size trails the NH-D15 G2 (140mm)
The catch
It gives ground on heat pipe count, where the NH-D15 G2 offers 8.
How We Chose These Coolers for 7800X3D
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- What we compared
- We set side by side six coolers on heat pipe count, fan size, height and warranty from manufacturer specifications. We did not test them in-house, and height and warranty are missing for at least one pick.
- The shared baseline
- All 6, from the Phantom Spirit 120 SE to the Freezer 36, state heat pipe count, fan size and fans included.
- Where the specs have gaps
- The Peerless Assassin 120 SE, the NH-D15 G2, the Dark Rock Elite and the Freezer 36 give no height; the Phantom Spirit 120 SE, the Peerless Assassin 120 SE, the Dark Rock Elite and the Phantom Spirit 120 Digital EVO give no warranty.
- Price range
- At our last check the picks ran from the Freezer 36 (under $50) to the NH-D15 G2 ($150 to $250).
