Copper Heatsink:
This heat sink provides a solution to reduce the temperature of components, suitable for cooling precision equipment, circuit boards, CPUs, IC chipboards, etc.

100% Copper Material:
Adopts high-quality pure copper material, copper's thermal conductivity is much more efficient than aluminum alloy, and the contact area is increased, allowing the accumulated heat to be released into the air faster.
In addition, the groove design further increases the heat dissipation area.

Easy Installation:
Comes with a dedicated thermal conductive sheet, easy to install by simply pasting it.
(Usually, it is shipped attached to the heat sink, but if it is not pre-pasted, please peel off the protective film on both sides of the thermal pad when installing.)

Quiet Operation:
Unlike cooling fans, there is zero operating noise, so you can work or play games without disturbing your concentration.

Quality Assurance:
We inspect all products thoroughly, but if there is any defect in the product you purchased, we will sincerely and promptly send you a replacement product. If there is a problem, please contact us. Please contact us at any time.

Where do your products come from?
We source inventory through liquidation and wholesale channels, including overstock, closeouts, shelf-pulls, and inspected customer returns from major retailers and distributors.

Why are your prices so much cheaper than retail?
We buy inventory in bulk and price items to move quickly. This reduces overhead and removes typical retail markups.

Are the products authentic?
We focus on legitimate sourcing channels and aim to describe items accurately with clear condition information.

What does “Like New” mean?
Like New items are in excellent condition with little to no signs of use. This can include items that were opened but are still in like-new condition.

Why do some items have different packaging?
Liquidation inventory may include items with opened or replacement packaging. Condition is always shown on the listing.

Do you combine shipping?
Yes—when possible, items may ship together. Shipping is calculated at checkout based on weight, dimensions, and destination.

Do you offer free shipping?
Yes—free shipping applies to orders $50+ (as shown on the site).

How fast do you ship and which carriers do you use?
Shipping options and timelines are shown at checkout. We typically use major carriers such as USPS, UPS, and FedEx depending on package and destination.
