Our Picks

Best for the i5-13400F1 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

Most 13400F builds.

Skip if

Skip it if heat pipe count matters most to you; the Peerless Assassin 120 SE offers 6.
ARCTIC Freezer 36

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.

  • Push-pull single tower

Cons

  • Heat pipe count trails the Peerless Assassin 120 SE (6)

The catch

The trade-off is heat pipe count; for more, the Peerless Assassin 120 SE offers 6.

Best Dual Tower2 of 6

Thermalright Peerless Assassin 120 SE

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.
Thermalright Peerless Assassin 120 SE

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.

Best for

Buyers who want two fans included.

Skip if

Skip it if price comes first: the Freezer 36 cost less when we checked.
ID-COOLING FROZN A620 PRO SE

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.

Best Easy Install4 of 6

be quiet! Pure Rock Pro 3 Black

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.
be quiet! Pure Rock Pro 3 Black

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.

Worth Considering5 of 6

be quiet! Dark Rock 5

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.

Skip if

If budget leads, the Freezer 36 was cheaper at our last price check.
be quiet! Dark Rock 5

Why we like it

A pre-installed mounting bridge makes fitting it easier, and a magnetic mesh cover hides the heat pipe ends. Its Silent Wings 4 fan has a tight blade tip clearance for quiet airflow. It matches the Peerless Assassin 120 SE, the Frozn A620 Pro SE and the Pure Rock Pro 3 on heat pipe count (6).

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.

Best RAM Clearance6 of 6

Noctua NH-U12S redux

The NH-U12S redux is a slim single tower that does not overhang the RAM slots.

Best for

Builds with tall RAM.

Skip if

Pass if a published heat pipe count matters; this one has none.
Noctua NH-U12S redux

Why we like it

It suits builds with tall memory. It is a lower-cost redux version of the NH-U12S, with an NF-P12 redux fan that is near silent at idle. It ships with an NF-P12 redux-1700 PWM fan, NT-H1 thermal paste and the SecuFirm2 mounting system, and it covers Intel LGA1700 and LGA1200 as well as AMD AM4.

Check that your case offers at least 158mm of CPU cooler clearance before ordering. It was priced above the Pure Rock Pro 3 and below the Dark Rock 5 at the time of writing. There is no published heat pipe count figure, whereas the Peerless Assassin 120 SE offers 6.

A case with purple-lit front fans and the motherboard area behind them
What we compared
We set side by side six coolers on heat pipe count, fan size, height and fans included, using each maker's published specs. We did not test them in-house, and heat pipe count and height are missing for at least one pick.
What every pick has in common
All 6, from the Freezer 36 to the NH-U12S redux, state fan size and fans included.
Where the specs have gaps
The NH-U12S redux gives no heat pipe count; the Freezer 36, the Peerless Assassin 120 SE, the Pure Rock Pro 3 and the Dark Rock 5 give no height.
Price range
At our last check the picks ran from the Freezer 36 (under $50) to the Dark Rock 5 ($50 to $100).

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

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

  1. Heat pipe count across these picks

Frequently Asked Questions

Which has the lowest height: the Frozn A620 Pro SE or the NH-U12S redux?

The Frozn A620 Pro SE is lowest on height at 157mm; the NH-U12S redux follows at 158mm, 1% apart. The Freezer 36, the Peerless Assassin 120 SE, the Pure Rock Pro 3 and the Dark Rock 5 don't state a height figure, so they sit outside this comparison; 2 of 6 picks are ranked.

What does the Dark Rock 5 add over the Freezer 36?

What it brings is heat pipe count (6 against 4). On our last price check the Freezer 36 was in the under $50 tier and the Dark Rock 5 in the $50 to $100 tier, with 4 other picks between them; pay the difference only if heat pipe count decides your purchase.

Why is the NH-U12S redux our Best RAM Clearance pick?

The label rests on a slim tower that clears the memory. The Freezer 36, the cheapest pick, sat in the under $50 tier against $50 to $100 here, without out-ranking it on any listed spec. It makes sense for builds with tall RAM.

What extras do the Freezer 36 and the Peerless Assassin 120 SE include?

The Freezer 36: a push-pull single tower. The Peerless Assassin 120 SE: a dual-tower heatsink. The Frozn A620 Pro SE: a 260W rating.

Who should choose the Freezer 36?

The Freezer 36 carries our Best for the i5-13400F label for a push-pull single tower with an LGA1700 contact frame. It ranks first of 6 here and sat in the under $50 tier at our last price check; it suits most 13400F builds.

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.
