Corsair A115 Twin Tower specifications and in-depth review

Corsair A115 Twin Tower

Manufacturer: Corsair

The Corsair A115 Twin Tower is a dual-tower air CPU cooler built around a twin-fan configuration designed to move heat efficiently away from the processor. With two fans running at up to 1600 RPM, the cooler balances thermal performance with noise output across a wide range of operating conditions. It ships with thermal paste included and uses fluid dynamic bearings, which generally contribute to smoother and more consistent fan operation over time.

The heatsink measures 164.8 mm tall, 153 mm wide, and 155 mm deep, with a total weight of 2200 g — figures worth checking against case clearance and motherboard specifications before installation. Audible noise ranges from a low of 5 dB up to 33.9 dB at maximum fan speed, while maximum airflow reaches 84.5 CFM. The cooler supports a broad range of CPU sockets covering Intel LGA 1150, 1151, 1155, 1200, 1700, and 1851, as well as AMD AM4 and AM5. It carries no RGB lighting or integrated display, and is backed by a five-year warranty.

Pros
  • Supports a broad range of CPU sockets across both Intel and AMD platforms, including LGA 1851 and AM5
  • Thermal paste is included in the box, allowing straightforward installation without additional purchases
  • Fluid dynamic bearings on the fans contribute to smoother and more consistent rotation over time
  • Minimum noise level of 5 dB means the cooler can operate very quietly at low loads
  • Backed by a five-year warranty, which is a notably long coverage period for a CPU cooler
Cons
  • At 2200 g, the cooler is quite heavy, which may place stress on the motherboard if used without additional support
  • The heatsink stands 164.8 mm tall and spans 153 mm wide, requiring careful clearance checks inside the case
  • No RGB lighting for users who prefer a visually coordinated build
  • Maximum noise level of 33.9 dB at full fan speed may be noticeable in quieter environments
Who is this for?

This cooler suits users who need broad CPU socket compatibility, covering a wide range of Intel and AMD platforms including the latest LGA 1851 and AM5, making it a practical fit for builders working with current-generation hardware or upgrading existing systems. The dual-fan air cooling setup with a maximum airflow of 84.5 CFM is well-suited for workstation or desktop environments where adequate case clearance is available and consistent thermal management under sustained loads is a priority. Users who prefer a clean, understated aesthetic without RGB lighting will also find the no-frills design aligned with their preferences.

Who is this NOT for?

Given its heatsink dimensions of 164.8 mm tall and 153 mm wide, this cooler is not well-suited for compact or small-form-factor cases where vertical and lateral clearance is limited. The total weight of 2200 g makes it a poor choice for users concerned about long-term motherboard stress, particularly in systems that may be transported or repositioned frequently. Additionally, users who prioritize a visually coordinated build with synchronized lighting will find this cooler lacking, as it includes no RGB functionality whatsoever.

Cooling:

Cooling type Air
Max fan RPM 1600 rpm
Max pump RPM 0 rpm
Max airflow 84.5 CFM
Number of fans 2

The Corsair A115 Twin Tower uses air cooling as its cooling method, relying on two fans to draw heat away from the heatsink. Those fans spin at a maximum of 1600 RPM, delivering a peak airflow of 84.5 CFM. As an air-based solution, it has no pump component, so the maximum pump RPM is zero by design.

Dimensions:

Heatsink/water block height 164.8 mm
Heatsink/water block width 153 mm
Heatsink/water block depth 155 mm

The Corsair A115 Twin Tower heatsink measures 164.8 mm in height, 153 mm in width, and 155 mm in depth. These dimensions reflect a sizeable dual-tower footprint, so verifying clearance within the chassis and around nearby motherboard components is advisable before installation.

General info:

CPU socket LGA 1851, LGA 1700, LGA 1200, LGA 1150, LGA 1151, LGA 1155, AM4, AM5
Audible noise (min) 5 dB
Audible noise (max) 33.9 dB
weight 2200 g
warranty period 5 years

The Corsair A115 Twin Tower is compatible with a wide range of CPU sockets, covering Intel LGA 1150, 1151, 1155, 1200, 1700, and 1851, as well as AMD AM4 and AM5. Audible noise spans from a quiet 5 dB at its lowest to a maximum of 33.9 dB under full load, while the cooler itself weighs 2200 g — a figure worth keeping in mind when assessing motherboard and case compatibility. It is backed by a 5-year warranty.

Features:

Fan bearings Fluid dynamic bearings
has RGB lighting ✕
Thermal paste Included
Has a display ✕

The fans on the Corsair A115 Twin Tower use fluid dynamic bearings, a bearing type associated with smoother rotation and reduced friction during operation. Thermal paste is included in the package, so no separate purchase is required for initial installation. The cooler does not feature RGB lighting or an integrated display, keeping the aesthetic straightforward and focused purely on function.

Final Verdict

The Corsair A115 Twin Tower is a straightforward, no-nonsense air CPU cooler that earns its place through wide platform compatibility and a dual-fan airflow setup delivering up to 84.5 CFM, making it a dependable option for users building or upgrading systems on current Intel or AMD hardware. Its fluid dynamic bearing fans, included thermal paste, and five-year warranty reflect a well-rounded package for desktop builds where reliability and long-term use matter. That said, its considerable weight and large heatsink footprint mean it demands careful case selection, and those wanting a visually expressive or compact setup will find it a poor match. For users prioritizing thermal coverage and socket versatility over aesthetics or size constraints, the A115 Twin Tower represents a technically capable and practically focused cooling solution.
