ID-COOLING IS-47-XT Low Profile CPU Cooler
Overview
The ID-COOLING IS-47-XT Low Profile CPU Cooler occupies a specific and unforgiving niche: cooling a desktop processor when vertical space is measured in millimeters, not centimeters. At 47mm total height, it fits where virtually no standard tower cooler can go. Low-profile cooling is a demanding category — you're asking a compact heatsink to do a job that usually requires much more mass. The answer here is a copper heatpipe design rather than a budget aluminum slab, which makes a real difference at this profile. The all-black finish isn't an afterthought either; it looks deliberate and clean inside a visible SFF case. For the price, it competes at a tier that more expensive rivals occupy.
Features & Benefits
Where this low-profile cooler earns its keep is in the engineering beneath the fins. The four copper heatpipes and copper base pull heat away from the CPU die far more efficiently than a single-material aluminum block could manage at this profile. The 92x92x15mm PWM fan is impressively slim — only 15mm thick — but still pushes up to 46 CFM, which is workable for low-to-mid TDP chips. At idle, PWM speed control drops the fan to near-inaudible levels; you'll hear your case fans long before this one. RAM clearance is rarely an issue thanks to the low-slung heatsink design. Intel users get plug-and-play mounting; AMD builders on AM4 or AM5 will need an extra bracket, sold separately.
Best For
This slim CPU cooler makes the most sense in a handful of specific situations. HTPC builders are the obvious fit — if your PC lives under a TV or inside a media cabinet where silence matters as much as thermals, the IS-47-XT's near-silent idle behavior and compact footprint are exactly what you need. Same goes for Mini-ITX cases with strict clearance limits; anything under 50mm of CPU cooler headroom narrows the field fast, and this one clears that bar comfortably. It also suits users running low-to-mid TDP processors — think 65W desktop chips or light productivity builds — where extreme thermal overhead isn't required. AMD users, note that the additional bracket is not included and adds both cost and a sourcing step.
User Feedback
Across reviews, a few consistent themes emerge. Installation gets frequent praise — most builders report that it drops into Intel builds without fuss, with the heatsink sitting flush and clear of surrounding components. Thermal performance under sustained heavy loads is where opinions divide: users on lighter workloads are largely satisfied, but those pushing 95W-plus processors under prolonged stress find the cooler reaching its limits sooner than they'd like. Fan noise at full speed is noticeably higher than the whisper-quiet idle, so expect a real difference between the two states. AMD bracket frustration surfaces repeatedly — not a dealbreaker, but buyers consistently flag that it should be included. Long-term durability reports are mostly positive, with no widespread bearing complaints after extended use.
Pros
- Fits cases with under 50mm CPU cooler clearance, solving a compatibility problem most coolers cannot.
- Four copper heatpipes and a copper base provide meaningfully better heat transfer than aluminum-only alternatives at this profile.
- PWM fan control keeps noise levels impressively low during light workloads and idle states.
- Heatsink geometry avoids RAM slot interference, even on cramped Mini-ITX motherboards.
- All-black finish looks clean and deliberate inside visible SFF or HTPC builds.
- Native Intel LGA1700 support means no adapter hassle for current-gen Intel builds.
- Lightweight at under 1.3 lbs, reducing stress on the motherboard PCB during transport.
- Ranked among the top performers in its category, reflecting strong real-world user satisfaction.
- Low 2.16W power draw adds virtually nothing to system power consumption.
Cons
- AMD AM4 and AM5 users must purchase a separate mounting bracket, adding cost and a sourcing step.
- Thermal headroom is limited — sustained high-TDP workloads will push this slim CPU cooler to its edge.
- The slim 15mm fan produces noticeably more noise at full speed than at idle; the gap is wider than expected.
- Not a viable option for overclocking; there is simply not enough heatsink mass to absorb the added heat.
- 46 CFM airflow, while adequate for modest CPUs, leaves little margin if case ventilation is poor.
- The AMD bracket is not included in the box despite AMD socket support being listed as a feature.
- At max RPM, the 46 dB noise rating is audible in a quiet room, which undercuts its HTPC appeal under load.
- Availability of the AMD bracket accessory may vary by region, creating an inconsistent buying experience.

Suitable for:
The ID-COOLING IS-47-XT Low Profile CPU Cooler is purpose-built for builders working within tight spatial constraints, and it genuinely excels in that context. If you're assembling an HTPC that lives in a media cabinet or on a shelf next to your television, the near-silent idle behavior and compact footprint make it a natural fit. Mini-ITX case builders with CPU clearance limits under 50mm will find the 47mm total height clears the bar comfortably, which eliminates a lot of frustrating compatibility hunting. It also works well for anyone running a 65W or similarly modest processor — light workstation tasks, home office productivity, basic media playback — where thermal demands stay within a sensible range. Builders who care about aesthetics in a visible build will appreciate the all-black design, which looks intentional rather than utilitarian inside a windowed panel.
Not suitable for:
The ID-COOLING IS-47-XT Low Profile CPU Cooler has a real thermal ceiling, and pushing past it will leave you frustrated. If your processor regularly runs at high TDP under sustained workloads — think video encoding, 3D rendering, or any CPU-intensive task that keeps the chip pegged for extended periods — this cooler will struggle to maintain safe temperatures, and you'll hear the fan working harder to compensate. Overclockers should look elsewhere entirely; there simply isn't enough heatsink mass to cope with the added heat output. AMD users on AM4 or AM5 platforms also face a practical friction point: the required mounting bracket is not included in the box, which means an extra purchase and potentially a sourcing delay before your build is complete. Anyone expecting whisper-quiet operation at full fan speed will also be disappointed — it is quiet at idle, but the gap between idle and full load is more noticeable than the spec sheet suggests.
Specifications
- Total Height: The cooler stands at 47mm from base to top, making it compatible with cases that enforce strict CPU cooler clearance limits.
- Fan Dimensions: The included fan measures 92x92x15mm, an unusually slim profile that allows it to fit within the 47mm total cooler height.
- Fan Type: A 4-pin PWM fan is included, enabling automatic speed adjustment based on CPU temperature signals from the motherboard.
- Max Fan Speed: The fan spins at up to 2200 RPM under full load, which represents its peak cooling and peak noise operating point.
- Max Airflow: At full speed, the fan moves up to 46 CFM of air through the heatsink fins, a reasonable figure for a 15mm-thick fan.
- Noise Level: Maximum rated noise output is 46 dB, measured at full fan speed; at lower PWM-controlled speeds, the cooler operates significantly quieter.
- Heatpipes: Four copper heatpipes run through the heatsink stack, transferring heat away from the CPU die and distributing it across the fin array.
- Base Material: The contact base is made of copper, which provides higher thermal conductivity than aluminum and improves heat transfer at the CPU interface.
- Power Draw: The fan consumes just 2.16W at maximum speed, contributing negligibly to total system power consumption.
- Voltage: The fan operates at 12V DC, standard for desktop PC fan headers.
- Intel Support: Native mounting support is included for Intel LGA1700, LGA1200, LGA1151, LGA1150, LGA1155, and LGA1156 sockets without any additional hardware.
- AMD Support: AM4 and AM5 socket compatibility is possible but requires a separately purchased mounting bracket not included in the retail package.
- Cooling Method: This is an air cooler; it uses forced convection via the included fan and passive conduction through the copper heatpipes and aluminum fin stack.
- Color: The entire cooler — heatsink body, fan frame, and fan blades — is finished in all-black for a consistent aesthetic in dark-themed builds.
- Weight: The cooler weighs 1.28 lbs, light enough to avoid placing significant stress on the motherboard PCB or socket retention mechanism.
- Connector Type: The fan uses a standard 4-pin PWM connector, compatible with any desktop motherboard fan header that supports PWM speed control.
