STEADY PRICEComputer & Office
What our readings say: Held between $2.51 and $2.57 across 41 days.
AliExpress prices this listing at 17.09 CNY. The $2.55 above is that figure converted by their affiliate API. AliExpress’s own site converts at a slightly different rate, so it may show a few percent less — the CNY number is the one neither of us converted.
Seller lists it at $5.11 — a claimed saving of $2.56. AliExpress does not verify that figure, and 38.3% of the listings we track make a claim in the same 50-59% range, so on its own it means very little.

21W/mK High Thermal Conductivity Thermal Pad 100x100mm Silicone Cooling Pad 0.5/1.0/1.5/2.0/2.5mm for CPU GPU Laptop Heatsink — listed under Computer & Office. Full specifications are on the AliExpress product page.
8 products in Computer & Office close enough to compare on price — 2 are cheaper than this one.
We track 3,626 products in Computer & Office. At $2.55, it sits below the middle of that category, which is $7.10 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 50% off. So do 35,155 other products we track — 38.3% of our whole catalogue claims a discount in the 50-59% band. At that frequency the figure is a listing convention rather than a signal. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.
AliExpress reports 275 orders for it. For comparison, the median listing we track in Computer & Office reports 135 — though a category holds very different kinds of thing, so read that as scale rather than as a ranking. Order counts come from AliExpress and are not a claim about price.
We have recorded this product’s price on 41 separate days since 2026-08-09, and it has moved 10 times in that window. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.
If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
All under $2.55 with at least 100 reported orders.
