From the Peerless Assassin 120 SE White to the NH-D15 G2 chromax.black: five air coolers ranked on heat pipe count and fan size, with who should skip each one.

By The PC Journal editorial team

12 min read5 products evaluated

Tower coolers remain the simplest strong cooling for gaming PCs. Every pick is a full-height tower, ordered by heat pipe count.

This is a research roundup, not a lab test: heat pipes, fan size and height come from each maker's published specs; nothing here was tested in-house, and a missing height is flagged, not filled in.

Our Picks

Noctua NH-D15 G2

Also Consider1 of 5

Noctua NH-D15 G2 on Amazon (opens in a new tab)

The NH-D15 G2 is Noctua's flagship: eight heat pipes, two 140mm fans and a six-year warranty.

Best for

Buyers who want offset design whose recessed lower fins clear the top PCIe slot.

Skip if

Price-first buyers should look at the Peerless Assassin 120 SE White, which cost less when we checked.

Why we like it

Its offset design keeps the top PCIe slot clear, but it is a large cooler, so check your case first. Its fans have a speed offset for acoustic fine-tuning, and there is 20% more fin area than the original NH-D15. On heat pipe count it ties with the NH-D15 G2 chromax.black at 8.

You also get 59mm RAM clearance with one fan fitted and NT-H2 paste in the box. Its price falls between the Phantom Spirit 120 Digital SNOW and the NH-D15 G2 chromax.black, based on our last check. Buyers who need a confirmed height should compare it with the Phantom Spirit 120 Digital EVO, which comes in at 160mm.

  • Fan size: 140mm
  • Warranty: 6-year
  • Fans included: 2

Cons

  • Costs more than the Peerless Assassin 120 SE White at the time of writing

Skip if

Price-first buyers should look at the Peerless Assassin 120 SE White, which cost less when we checked.

Why we like it

Its offset design clears the top PCIe slot and leaves 59mm for RAM. It matches the NH-D15 G2 on heat pipe count (8). It matches the NH-D15 G2 on fan size (140mm).

Thermalright Peerless Assassin 120 SE ARGB White

Lowest Price Here5 of 5

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

The Peerless Assassin 120 SE White is built around a white heatsink with white ARGB fans, with a 25.6dB(A) noise rating on top.

Best for

Keeping the budget tight.

Skip if

Skip it if heat pipe count matters most to you; the NH-D15 G2 offers 8.

Why we like it

On the spec sheet, it offers a 6 heat pipe count and offers a 120mm fan size. At 155mm tall it fits most mid-towers, and its two TL-C12C-S ARGB fans add lighting. The white heatsink and fans suit an all-white build.

Mounting hardware covers Intel LGA115x to LGA1700 and AMD AM4/AM5. Its 6 heat pipe count is the lowest in this group; the NH-D15 G2 leads at 8. It matches the Phantom Spirit 120 Digital EVO and the Phantom Spirit 120 Digital SNOW on fan size (120mm).

The maker names AM5 but not Intel LGA1851, so check the maker's site if you are building on Core Ultra. No other pick here cost less at our last price check, and the Phantom Spirit 120 Digital EVO was closest.

Key dimensions & specs

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

Pros

  • Two fans included
  • White heatsink with white ARGB fans
  • 25.6dB(A) noise rating
  • Undercutting the Phantom Spirit 120 Digital EVO on price when we checked

Cons
