## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09095:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE09095:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

If your Pi 4 is running hot, the first, recommended course of action is to add a heatsink! This particular heatsink comes with thermal tape pre-applied, just peel and stick to the main ICs on your Raspberry Pi 4 to extract any excess heat. There's plenty of surface area, allowing great heat dissipation. Application of this particular heatsink will increase the thermal mass of the IC's to wick away heat and keep your temperature down.

It's a simple upgrade, peel and stick for better heat dissipation. More a more indepth look at how you can take additional steps to cool your RPi 4, take a look at our guide on [keeping your Pi cool](https://core-electronics.com.au/guides/raspberry-pi/cooling-your-raspberry-pi/) , then show off how cool you can get your Pi with [a stress test](https://core-electronics.com.au/guides/raspberry-pi/how-to-stress-test-temperature-on-raspberry-pi/)!

### Specifications:

- Dimensions 40 mm x 30 mm x 5mm
- Aluminum body with insulating matte black coating
- Pre-applied thermal adhesive for the Pi's SoC's
