Desktop DDR memory sticks run hot under gaming sessions, video rendering, and memory-intensive workloads — and most budget or mid-range kits ship without any RAM heatsink spreader at all. Elevated temperatures cause instability, throttling, and in extreme cases premature chip degradation. Builders who push XMP or EXPO profiles, or who run multiple sticks in a warm case, need an affordable way to add thermal protection without replacing their entire memory kit.
Each order includes 2 aluminum RAM heatsink spreaders in your chosen color (Black ×2 or Red ×2) — enough to cover a standard dual-channel kit. Each spreader measures 150 mm × 35 mm × 10 mm (5.9" × 1.38" × 0.39") and weighs approximately 55 g (1.9 oz) per piece. The body is CNC machined from aluminum alloy for consistent wall thickness and flat contact surfaces. Available in matte black and anodized red to match your build aesthetic.
Typical use cases include adding thermal protection to bare DDR4 or DDR5 sticks in a mid-tower gaming PC build, improving memory stability during XMP overclocking on an Intel or AMD desktop platform, and giving a visual upgrade to a windowed case where RGB-adjacent red or black RAM coolers complement the overall theme. The passive design means zero noise and zero power draw.

Each spreader measures 150 mm × 35 mm × 10 mm (approximately 5.9" × 1.38" × 0.39"). It is designed to fit standard-height and most low-profile desktop DDR memory sticks (DDR3, DDR4, DDR5). Measure your RAM stick’s length and height before purchasing to confirm fitment. If your sticks already have a factory heat spreader installed, remove it first or check that the combined thickness does not exceed your motherboard’s clearance.
Each order includes 2 aluminum RAM heatsink spreaders in your chosen color (Black ×2 or Red ×2). This is enough to cover a standard dual-channel memory kit (2 sticks). If you are running a quad-channel configuration (4 sticks), you would need to order two sets.
Yes. Aluminum heat spreaders increase the surface area available for heat dissipation from the RAM chips. Under sustained workloads such as gaming, video rendering, or memory-intensive applications, a RAM heatsink spreader can generally reduce module temperatures by 5–10°C, helping maintain stable operation and reducing the risk of thermal throttling or instability during overclocked operation.
The spreader is designed for the standard desktop DIMM form factor, which covers most DDR3, DDR4, and DDR5 modules. The key dimensions to check are stick length (typically 133 mm for standard DIMMs) and height. SO-DIMM laptop modules are a different, smaller form factor and are not compatible with this spreader.
The spreader adds approximately 10 mm of thickness to each side of the RAM stick. If your CPU cooler has limited clearance above the first DIMM slot, measure the available space before installing. In most mid-tower and full-tower cases this is not an issue, but compact Mini-ITX builds may have tighter constraints. Check your CPU cooler’s RAM clearance specification if you are unsure.
Yes. Enthusiasts who run XMP or EXPO profiles, or who manually overclock their RAM, generally benefit from additional thermal management. Keeping memory chips cooler during overclocked operation can improve stability and longevity. The CNC-machined aluminum construction provides consistent contact across the RAM chip surface for effective heat transfer during high-frequency DDR4 or DDR5 overclocking.
This RAM heatsink spreader is designed for standard indoor desktop PC use. The aluminum body offers basic corrosion resistance, but it is not rated for outdoor, high-humidity, or condensation-prone environments. For industrial or ruggedized deployments, additional enclosure protection is recommended.
The spreader is typically secured using a thermal adhesive pad or thermal tape that bonds the aluminum body to the RAM chip surface. This ensures good thermal contact without damaging the PCB or requiring any tools. Please refer to the product images and included instructions for the exact attachment method for your unit.
