SKTC KT-27 Low-Profile CPU Cooler — 27mm Slim Design for HTPC and 1U Builds

Building a compact HTPC, a living room PC, or a 1U server means working within strict height constraints that standard tower coolers simply cannot meet. Most aftermarket CPU coolers stand 130–165mm tall — far too large for slim cases. The SKTC KT-27 low-profile CPU cooler is engineered specifically for space-constrained builds, measuring just 27mm in total height (excluding backplate) while still delivering active PWM-controlled cooling. It’s built for system integrators, home theater PC builders, and compact desktop users who need reliable CPU cooling without sacrificing case compatibility.

Each order includes 1 × KT-27 cooler assembly (aluminum fin heatsink with copper-core base + 80mm PWM fan pre-mounted) and a backplate mounting kit for Intel LGA115X. The heatsink body is constructed from aluminum fins with a copper-core base insert for improved heat transfer. Overall dimensions: 88 × 88 × 27mm (3.46" × 3.46" × 1.06"), not including the backplate. The integrated fan measures 80 × 80 × 15mm (3.15" × 3.15" × 0.59").

This cooler is ideal for HTPC and living room PC builds using Intel LGA115X processors where case height is limited to 30–40mm above the motherboard, as a low-profile CPU cooler for 1U server chassis that require slim active cooling solutions, and as a quiet compact CPU cooler for mini-ITX slim cases where standard tower coolers are physically incompatible.

🔌 Compatibility: Intel LGA115X only (LGA1150 / LGA1151 / LGA1155 / LGA1156) — 75 × 75mm backplate hole pattern. Not compatible with Intel LGA1700, LGA1200, or AMD AM4/AM5. Fan connector: 4-Pin PWM.

✅ Key Features of These Low-Profile CPU Coolers

📏27mm Ultra-Slim Profile — At just 27mm in total height (excluding backplate), the KT-27 fits inside HTPC cases and 1U server chassis that impose strict CPU cooler height limits. This makes it one of the slimmest active CPU coolers available for Intel LGA115X platforms, enabling builds that are physically impossible with standard tower coolers.
🧲Copper-Core Base Insert — A copper core is embedded in the aluminum base plate directly beneath the CPU contact surface. Copper’s thermal conductivity is approximately 4× higher than aluminum, allowing heat to be drawn away from the CPU heat spreader rapidly and distributed into the surrounding aluminum fin array for dissipation.
⚙️80mm 4-Pin PWM Fan with Smart Temperature Control — The 8015 fan (80 × 80 × 15mm) uses a 4-pin PWM connector, allowing your motherboard to automatically scale fan speed between idle and 2500 RPM based on CPU temperature. This keeps the cooler quiet during light workloads and ramps up airflow when the CPU is under load.
💨57.5 CFM Airflow in a Compact Package — Despite its slim 15mm fan thickness, the 80mm fan delivers 57.5 CFM of airflow across the aluminum fin stack. This is sufficient for mainstream Intel LGA115X CPUs operating at stock TDP, making the KT-27 a practical low-profile CPU cooler for HTPC and compact desktop applications.
🔇Hydraulic Bearing for Quiet Long-Term Operation — The fan uses a hydraulic bearing (fluid dynamic bearing), which runs quieter and more smoothly than standard sleeve bearings. At PWM-controlled low speeds, the cooler is generally inaudible in a closed HTPC case, making it well-suited for living room and home office environments.
🔧Backplate Mounting for Intel LGA115X — The KT-27 installs via a backplate system using the standard 75 × 75mm Intel LGA115X hole pattern. Backplate mounting provides more secure and even clamping pressure on the CPU heat spreader compared to push-pin retention, improving thermal contact consistency.

⚠️ Before ordering: Confirm your CPU socket is Intel LGA115X (LGA1150/1151/1155/1156). This cooler is not compatible with LGA1700, LGA1200, or any AMD socket. Check your case’s maximum CPU cooler height — the KT-27 measures 27mm excluding the backplate. Thermal paste may not be included; apply thermal compound before installation if needed.

❓ Frequently Asked Questions

What CPU sockets does the SKTC KT-27 support?

The KT-27 supports Intel LGA115X sockets only: LGA1150, LGA1151, LGA1155, and LGA1156. It uses a 75 × 75mm backplate mounting pattern. It is not compatible with Intel LGA1700, LGA1200, or any AMD socket (AM4, AM5, etc.). Confirm your motherboard socket before ordering.

How tall is this cooler and will it fit my HTPC or 1U case?

The KT-27 measures 88 × 88 × 27mm (approximately 3.46" × 3.46" × 1.06") in total height, not including the backplate. At 27mm, it is specifically designed for HTPC cases and 1U server chassis that require low-profile CPU coolers. Check your case’s maximum CPU cooler height specification to confirm fit before ordering.

What CPUs is this cooler suitable for?

The KT-27 is designed for mainstream Intel LGA115X processors including Intel Core i3, i5, Celeron, and Pentium series. It is generally suitable for CPUs with a TDP up to approximately 65W at stock speeds. For higher-TDP processors or overclocked configurations, a larger cooler is recommended.

How loud is the 80mm fan during operation?

The 80mm fan operates at up to 2500 RPM ±10% with a noise level of 25 dBA ±10%. At lower PWM-controlled speeds, noise is generally well below 20 dBA. The hydraulic bearing design reduces bearing noise compared to sleeve bearing fans, making this cooler suitable for quiet HTPC environments.

Does this cooler include thermal paste and a backplate?

The KT-27 includes a backplate mounting kit for Intel LGA115X (75 × 75mm hole pattern). Please confirm whether thermal paste is included in the package before installation — if not included, apply a pea-sized amount of thermal compound to the CPU heat spreader before mounting the cooler.

What connector type does the fan use — PWM or DC?

The fan uses a 4-pin PWM (small 4-pin) connector, allowing your motherboard to automatically adjust fan speed between idle and 2500 RPM based on CPU temperature. This is compatible with standard 4-pin PWM headers on all major Intel platform motherboards.

Why choose a low-profile cooler over a standard tower cooler?

Standard tower coolers typically measure 130–165mm in height, which is incompatible with HTPC cases, 1U server chassis, and slim mini-ITX enclosures. A low-profile cooler like the KT-27 at 27mm fits within these space-constrained environments while still providing active PWM-controlled cooling. If your build uses a standard mid-tower case, a taller tower cooler will generally offer better thermal performance for the same CPU.

What is the copper-core base design and why does it matter?

The KT-27 uses a copper-core insert embedded in the aluminum base plate. Copper has approximately 4× higher thermal conductivity than aluminum, so the copper core rapidly draws heat away from the CPU heat spreader and transfers it into the surrounding aluminum fin structure. This hybrid design improves heat dissipation compared to a pure aluminum base — particularly important in a low-profile cooler where fin surface area is limited by height constraints.
