works good fits memory without clashes. Cant check temperature reduction as new high performance memory

Helps cool memory

📦 Specs: 10pcs pack Each heatsink: 70mm x 20mm x 6mm (approx.) Material: Anodized aluminum Adhesive backing (thermal tape pre-applied) --- 🧠 Objective Impressions: If you’re upgrading your laptop RAM or building a compact mini-PC, these little slabs of aluminum are a no-brainer. They’re super light, cut to size for SODIMM modules, and pre-applied with decent thermal adhesive. The finish feels durable, and the ridges help increase surface area for airflow (as limited as that might be in a laptop chassis). 🎯 Subjective Thoughts: Look, these aren’t miracle workers—but they’re cheap insurance. I used them on a pair of DDR4 SODIMMs running hot inside a poorly ventilated NUC. Temps dropped about 3–5°C under stress—not night and day, but enough to extend lifespan. They also add a subtle "modder’s touch" without looking tacky. No warping, no gooey adhesive issues. 📉 Downside? The thermal pads aren’t premium-grade, and the adhesive loses grip if repositioned—so aim once and commit. 💬 Final Verdict: Budget thermal control that punches above its size. Not flashy, but functional. And for less than a combo meal? Heat me up. 🔖 HiTekHQ – Tech Reviews Without the Fluff.

Super easy to apply. I would recommend laying down some kapton tape if you're putting the heatsink on the side of the ram closest to the motherboard. One of the reviewers mentioned that his laptop short circuited because the copper came in contact with the motherboard. This is mostly user error but some blame can be put on the manufacturer. Manufacturer should have a warning to check clearance after adding the the heatsink or provide insulating tape and just make it one of the steps for install. First time folks upgrading their laptop wouldn't think to do this but veterans and repair shops would and do.

There is not much mass here to collect heat, nor much surface area to dissipate the heat.

It works great. I copper plated everything in my laptop. It now runs 20-30c cooler.

As advertised, seems to help with heat transfer. Great with ptm7950

Giving this only three starts because of two issues: 1) the heatsink is only large enough for single row chip modules. For double row sticks - i.e. the ones with higher capacity - it will leave parts of the chips uncovered. 2) I do not trust the included adhesive to hold the heatsinks in place over long periods of time and had to put a makeshift clip to secure them in place. It would be disastrous for a piece of copper to fall onto the motherboard and shortcircuit random traces.
