VRM Heat Sinks

Keeping your power stable gets hard when VRM chips heat up fast in small motherboard areas. Our VRM Heat Sinks, made from aluminum or copper, remove heat quickly to prevent crashes and maintain system performance. 

Base Material

Aluminum or copper; specific alloys customizable upon request

Thermal Resistance

0.2°C/W to 1.5°C/W, optimized for VRM low-profile efficiency

Heat Dissipation Capacity

15 W to 150 W, suited for VRM power phases (e.g., 1-10 A per phase)

Dimensions

Width: 20 mm to 100 mm; Height: 10 mm to 50 mm; Depth: 20 mm to 120 mm (customizable to fit VRM layouts)

Weight

0.05 kg to 1.5 kg, depending on material and size for compact VRM integration

Product Description

Hot VRMs in tight spaces can disrupt power delivery, damaging boards or slowing equipment. Our heat sinks address this with compact designs, ensuring consistent operation every time. 

Fin Design

Extruded or skived fins (straight or micro-fin); fin pitch: 1 mm to 4 mm for tight airflow

Mounting Type

Screw-mount, clip-on, or adhesive pads; designed for VRM PCB attachment

Cooling Method

Passive (air-cooled) or active (fan-assisted), depending on VRM load and case airflow

Operating Temperature Range

0°C to 100°C, with maximum allowable base rise of 30°C above ambient

Airflow Compatibility

Supports 5 CFM to 100 CFM, effective with case or CPU fan airflow in VRM setups

Surface Finish

Anodized (aluminum) or nickel-plated (copper) for corrosion resistance and heat transfer

Noise Contribution

Silent (passive) or <30 dB (active cooling), minimal impact in PC/server systems

Durability

Rated for 70,000+ hours under continuous VRM operation

Environmental Resistance

Resistant to dust (IP53) and vibration (IEC 60068-2-6) in desktop/server environments

Standards Compliance

Meets RoHS, UL 94V-0, and IPC-9592 standards for VRM safety and performance

Thermal Interface Compatibility

Compatible with thermal pads or grease for VRM chip contact

Technical Advantages

Our VRM heat sinks attach firmly with clips or pads, drawing heat directly from small chips. They operate with case air or small fans, shifting heat away quickly in limited spaces. 

Fins cut thin or shaped flat capture airflow well, cooling VRMs without extra size. This efficient design keeps boards lightweight and cool, regardless of demand.

Industry Applications

Gaming PCs

Removes heat from VRMs on motherboards, keeping games running fast and smooth all night. 

Server Racks

Cools power chips in dense server trays, maintaining data flow for heavy workloads. 

Graphics Cards

Pulls heat from GPU power zones, ensuring steady frame rates in demanding renders. 

Laptops

Takes heat from small VRM sections, preserving battery life during mobile use. 

Workstations

Manages heat in professional PC power lines, supporting glitch-free edits or simulations daily. 

Overclock Kits

Clears heat from enhanced VRMs, allowing high clock speeds without damage. 

Stable Cooling for VRM Efficiency

VRM chips in confined areas need quick heat removal to deliver power reliably. Our heat sinks stay quiet under 30 dB, managing 15 W to 150 W with ease. 

Excess heat can interrupt systems or shorten lifespan, leading to repairs or lost productivity. We design ours slim, from 20 mm to 100 mm wide, to keep your equipment cool and operational. 

VRM Heat Sinks

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How do your VRM heat sinks improve system stability in computing setups?

Our VRM heat sinks manage heat loads from 15 W to 150 W with thermal resistance as low as 0.2°C/W, keeping power chips stable under heavy use. This control reduces crash risks, ensuring reliable performance for demanding PC or server operations. 

What options do we have to keep your VRM heat sinks small for our designs?

We offer compact sizes from 20 mm to 100 mm wide, with aluminum or copper builds to match heat needs without extra bulk. This range lets you fit cooling into tight boards, meeting space limits while maintaining efficiency. 

How do your heat sinks handle heat flux in high-power VRM zones?

Our heat sinks take on heat flux up to 10 W/cm² with thin fins, pulling heat fast from dense power areas. This capability keeps VRMs cool in tough loads, preventing slowdowns or damage in graphics or overclocked systems. 

What testing processes back up the reliability of your VRM heat sinks for our production?

We test our heat sinks to IPC-9592 and MIL-STD-810 standards, checking heat, vibration, and durability under real-world stress. This validation ensures you get parts that hold up, cutting risks and speeding up your build approvals. 

Can your VRM heat sinks support both prototype builds and full-scale production runs?

Yes, our heat sinks come in sizes from 20 mm to 120 mm deep with clip-on or screw mounts, fitting small tests or big batches. This flexibility simplifies your scaling process, keeping costs low and delivery fast across stages.
