Our Picks

ARCTIC Freezer 36

Best for the i5-13400F1 of 6

ARCTIC Freezer 36 on Amazon (opens in a new tab)

The Freezer 36 is a single tower with a push-pull fan pair at a very low price.

Best for

Most 13400F builds.

Skip if

Skip it if heat pipe count matters most to you; the Peerless Assassin 120 SE offers 6.

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. On heat pipe count it trails the group at 4, while the Peerless Assassin 120 SE offers 6. It undercut the Frozn A620 Pro SE and every other pick on price at the time of writing.

Key dimensions & 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 Peerless Assassin 120 SE (6)
Thermalright Peerless Assassin 120 SE

Best Dual Tower2 of 6

Thermalright Peerless Assassin 120 SE on Amazon (opens in a new tab)

The Peerless Assassin 120 SE is the budget dual tower most builders start with.

Best for

Quieter fans under load.

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.

It matches the Frozn A620 Pro SE, the Pure Rock Pro 3 and the Dark Rock 5 on heat pipe count (6). It also offers 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.

When we checked, only the Frozn A620 Pro SE and cheaper picks cost less, and the Pure Rock Pro 3 cost more. If you want a confirmed height, look to the Frozn A620 Pro SE instead: it comes in at 157mm, while this one gives no figure.

Key dimensions & specs

  • Heat pipes: 6
  • Fan size: 120mm
  • Fans included: 2
  • Sockets named: AM5, AM4, Intel

Pros

  • Two fans included
  • Dual-tower heatsink
  • 25.6dB(A) noise rating
  • Heat pipe count of 6, ahead of the Freezer 36

Cons

  • Costs more than the Freezer 36 at the time of writing

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

Its dual-tower heatsink and two 120mm PWM fans stand 157mm tall, which fits most tower cases. The black finish suits a dark interior. Its RAM clearance of 40mm fits standard-height memory under the front fan.

It is rated at 27.2dB(A) maximum noise. Its two PWM fans slow down at idle. On heat pipe count it ties with the Peerless Assassin 120 SE, the Pure Rock Pro 3 and the Dark Rock 5 at 6.

Check that your case offers at least 157mm of CPU cooler clearance before ordering. On price it sat second of 6, between the cheaper Freezer 36 and the pricier Peerless Assassin 120 SE, at the time of writing.

Key dimensions & specs

  • Heat pipes: 6
  • Fan size: 120mm
  • Height: 157mm
  • Fans included: 2

Pros

  • Two fans included
  • 260W rating

Best Easy Install4 of 6

be quiet! Pure Rock Pro 3 Black on Amazon (opens in a new tab)

The Pure Rock Pro 3 is a black single-fan tower rated at 250W.

Best for

First-time builders.

Skip if

Price-first buyers should look at the Freezer 36, which cost less when we checked.

Why we like it

It is easy to mount and leaves room around the socket. Six black copper heat pipes and a nickel-plated base sit under a Pure Wings 3 PWM fan. It is rated for 250W.

Its compact offset design improves RAM and VRM clearance, and the fan height can be adjusted. On heat pipe count it ties with the Peerless Assassin 120 SE, the Frozn A620 Pro SE and the Dark Rock 5 at 6. Its price falls between the Peerless Assassin 120 SE and the NH-U12S redux, based on our last check. Buyers who need a confirmed height should compare it with the Frozn A620 Pro SE, which comes in at 157mm.

Key dimensions & specs

  • Heat pipes: 6
  • Fan size: 120mm
  • Fans included: 1

Pros

  • 250W TDP rating
  • Pure Wings 3 PWM fan
  • Six black-coated heat pipes
  • Heat pipe count of 6, ahead of the Freezer 36

Cons

  • Costs more than the Freezer 36 at the time of writing
be quiet! Dark Rock 5

Worth Considering5 of 6

be quiet! Dark Rock 5 on Amazon (opens in a new tab)

The Dark Rock 5 is an asymmetrical single tower with six heat pipes that clears RAM and VRM heatsinks.

Best for

Buyers who want asymmetrical heatsink that clears ram and vrm heatsinks.

It also offers a simplified mounting system. Only the NH-U12S redux came close to it on price at the time of writing; it cost the most of the 6 picks. There is no published height figure, whereas the Frozn A620 Pro SE comes in at 157mm.

Key dimensions & specs

  • Heat pipes: 6
  • Fan size: 120mm
  • Fans included: 1

Pros

  • Asymmetrical heatsink that clears RAM and VRM heatsinks
  • Silent Wings 4 fan
  • Simplified mounting system

How We Chose These Coolers for i5-13400F

Each pick was assessed across 4 criteria weighted for real-world use.

Cooling hardware
We noted heat pipes, fan size and fan count from each listing.
Support
We recorded warranty length where the maker states it.
Sockets
We checked that each maker names current AM5 and Intel LGA1851 support.
Fit
We compared listed heights and footprints, since case and RAM clearance decide what fits.

What to Look for in a Cooler for i5-13400F

Key buying criteria so you get the right fit the first time.

  1. Size the cooler to the CPU

    A 65W chip runs well on a single tower or a good low-profile cooler. Chips rated at 120W to 170W need a dual tower or an AIO to hold their boost clocks without loud fans.

  2. Watch RAM clearance

    Large towers and low-profile coolers can overhang the memory slots. Tall RAM heatsinks may force you to raise a fan or pick a slimmer cooler.

    Makers publish RAM clearance figures; check them against your memory's height.

  3. Bigger fans can spin slower

    140mm fans move the same air as 120mm fans at lower speed, so larger coolers are often quieter at the same load.

    Fan curves in the BIOS matter as much as the cooler.

  4. Check the cooler height against your case

    Every case offers a maximum CPU cooler height. Tower coolers run from about 150mm to 170mm, and low-profile coolers from under 40mm to about 70mm.

    Leave a few millimetres for the side panel.

  5. Confirm the mounting kit

    Check that the cooler lists your socket: AM5 and AM4 share mounting, while Intel LGA1851 and LGA1700 share hole spacing. Older coolers may need a free or paid adapter.

  6. Warranty reflects fan life

    Coolers have few failure points besides the fans. Longer warranties, such as Noctua's and Arctic's six years, cover the parts most likely to wear.

Frequently Asked Questions

Which way should the fans face?

Point the airflow from the front of the case towards the rear exhaust fan. Most tower coolers mount this way by default.

Will a tower cooler block my RAM?

Some do. Check the maker's RAM clearance figure against your memory's height, especially with tall heatsinks or RGB modules.

Do I need to buy thermal paste?

Most coolers include paste, and some ship it pre-applied. Buy a tube only if you plan to remount the cooler.

What cooler does a 65W CPU need?

A single-tower cooler handles it easily; a good low-profile cooler works in small cases.

Is an air cooler as good as an AIO?

A large dual-tower cooler matches many 240mm AIOs and has no pump to fail. AIOs help with very hot CPUs and free up space around the socket.

Do AM4 coolers fit AM5?

Yes, AM5 keeps AM4's mounting, so most AM4 coolers fit. Check the maker's compatibility list to be sure.

Bottom Line

The ARCTIC Freezer 36 is enough for a 13400F at a very low price. The Peerless Assassin 120 SE runs quieter, and the NH-U12S redux suits tall RAM.
