6 Best Alternatives to the WithFlying Thermal Pad 15.8 W/mK (2026)
As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
You are looking for withflying thermal pad 15 8 w mk alternatives because the original pad may not fit your specific gap or application. The WithFlying 15.8 W/mK pad offers high thermal conductivity and electrical safety for GPUs and consoles. It is non-conductive and handles temperatures up to 205 ℃. However, you might need a different thickness or a rigid heatsink instead of a soft pad. The original is a flexible sheet, which limits use on components that require solid heat spreading.
We selected these 6 alternatives because their specifications overlap with your cooling needs. Some options provide copper construction for better heat dissipation on M.2 SSDs. Others offer different thicknesses to fill precise gaps in laptops or PS5 consoles. You can choose based on height clearance, material conductivity, or device compatibility. Each product listed addresses specific constraints that the standard thermal pad cannot solve. Review the specs to find the right fit for your build.
Our top pick: WithFlying 15.8 W/mK 100x100x2.5mm Thermal Pad.
How alternatives differ from WithFlying
Easycargo 100-Piece 15mm Copper Shim Kit
The Easycargo Copper Shim Kit replaces the soft silicone pad with rigid copper shims. You get precise thickness control for M.2 SSD gaps, whereas the WithFlying pad fills irregular spaces on GPUs. This kit lacks thermal conductivity metrics, relying on copper’s natural transfer properties. It is ideal if you need exact clearance adjustments rather than gap-filling compliance. You sacrifice the non-conductive safety of the WithFlying pad for the structural rigidity of metal. Choose this if your primary goal is fitting a low-profile SSD in a tight console slot.
Icepc Graphene Copper M.2 Heatsink
The Icepc Graphene Copper Heatsink offers active passive cooling for NVMe drives, unlike the passive WithFlying pad used for component gaps. It features a 2mm height and copper construction, providing a dedicated heat spreader for SSDs. The WithFlying pad is better for filling voids between chips and heatsinks. You gain a complete cooling solution for M.2 slots but lose the ability to customize pad shapes for irregular gaps. This option suits users needing to cool laptop or PS5 SSDs directly, rather than managing thermal interface material between components.
JOYJOM 2mm Graphite-Coated Copper M.2 Heatsink
The JOYJOM Heatsink includes a 2mm thermal pad but focuses on cooling M.2 SSDs with pure copper. It provides a larger surface area for heat dissipation compared to the small WithFlying pad squares. The included pad is thinner than the 2.5mm WithFlying option, making it suitable for tighter laptop clearances. You get a complete heatsink solution instead of just interface material. This is best for builders needing to cool SSDs in constrained spaces, rather than those filling gaps between GPU memory chips or VRMs with custom-sized pads.
Haojiaho 6mm Pure Copper M.2 2280 Heatsink
The Haojiaho 6mm Heatsink uses a thicker thermal pad than the 2.5mm WithFlying option, designed for desktop M.2 slots with ample space. It offers robust copper cooling for larger SSDs, whereas the WithFlying pad is for smaller component gaps. The 6mm profile is too bulky for most laptops, limiting its use to desktops or consoles. You gain significant cooling capacity for high-performance drives but lose the versatility of cutting pads to fit irregular shapes. Choose this if you have a desktop motherboard with tall M.2 slots requiring substantial heat transfer.
Haojiaho 67x18x2mm Pure Copper M.2 Heatsink
The Haojiaho 2mm Heatsink provides a compact copper solution for tight spaces, similar to the small footprint of the WithFlying pad. It includes a thermal pad for SSD cooling, focusing on M.2 drives rather than GPU or console gaps. The 2mm height is ideal for low-profile builds, unlike the thicker WithFlying options. You get a dedicated heatsink for SSDs but cannot use it to fill gaps between electronic components. This is best for users needing to cool M.2 SSDs in small form factor PCs or consoles where space is extremely limited.
WAVLINK Copper M.2 2280 Heatsink
The WAVLINK Copper Heatsink is designed for 2280 NVMe SSDs, offering a dedicated cooling surface rather than a gap-filling pad. It features a 2280 form factor, making it incompatible with the versatile, cuttable nature of the WithFlying pad. You gain a specialized solution for SSD thermal management but lose the ability to customize the interface material for other components. This option suits users who need to cool specific SSD models in laptops or consoles, rather than those needing flexible thermal pads for various electronic gaps.

Frequently asked questions
Can I use copper shims instead of a thermal pad for M.2 SSDs?
Yes, rigid copper shims like the Easycargo kit offer precise thickness control for M.2 gaps. Unlike soft pads, they do not compress. You must measure the gap exactly. The kit includes various thicknesses to fit different SSD heights. This method works well when you need a fixed, stable clearance rather than conforming to irregular surfaces.
What is the best thermal pad thickness for PS5 M.2 expansion?
The ideal thickness depends on your specific console model and SSD clearance. The Haojiaho 2mm heatsink suits tight spaces, while the 6mm version offers more robust cooling for desktops or consoles with ample room. You should check your motherboard manual for recommended gap sizes. Using a pad that is too thick can prevent proper seating.
Do these heatsinks include thermal pads for installation?
Most listed heatsinks come with pre-applied thermal pads. The Icepc, JOYJOM, Haojiaho, and WAVLINK models all feature integrated pads. This simplifies installation by removing the need to cut and apply separate pads. You simply peel the backing and attach the heatsink directly to the SSD. Verify the thickness matches your available clearance before purchase.
Is pure copper better than aluminum for M.2 cooling?
Pure copper conducts heat more efficiently than aluminum. All listed alternatives, including the Easycargo shims and Haojiaho heatsinks, use copper construction. This material helps dissipate heat from the SSD faster. The trade-off is weight. Copper products are heavier, which may matter in ultrathin laptops. For desktops and consoles, the thermal advantage is significant.
How do I choose between a shim kit and a full heatsink?
Choose a shim kit if you only need to fill a gap for contact with an existing cooler. The Easycargo kit provides rigid copper layers for precise spacing. Choose a full heatsink if you need active surface area for heat dissipation. The JOYJOM or Icepc models add mass to draw heat away from the SSD. Heatsinks are better for sustained loads.
Are these thermal pads electrically safe for use near components?
Yes, the WithFlying pad is non-conductive and safe for use near sensitive electronics. It prevents short circuits on GPUs and consoles. Most copper heatsinks also rely on non-conductive thermal pads for contact. Ensure the pad covers all necessary areas without bridging unintended contacts. This electrical safety is critical for protecting your hardware during operation.
Can I cut the WithFlying thermal pad to custom sizes?
Yes, the WithFlying pad allows you to cut it to fit specific gaps. It comes in large sheets, such as 100x100mm, for customization. This is ideal for GPUs or consoles with irregular spacing. You can trim the pad to match the exact dimensions of your memory chips. This flexibility makes it superior to pre-sized pads for unique builds.
