Moreover, all of them have an adhesive tape on their base so you can easily peel the sticker away and put the heat sinks to their respective chips. \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eSpecifications:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e14mm(L) x 14mm(W) x 5mm(H) Heatsink for Soc 1x\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e9mm(L) x 9mm(W) x 4mm(H) Heatsink for Voltage Regulator 1x\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e9mm(L) x 9mm(W) x 4mm(H) Heatsink for LAN9512 1x\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eLibrary: \u003c\/span\u003eNone\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eInclusions: \u003c\/span\u003e \u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e1 x heat sink for SoC\u003c\/li\u003e\n\u003cli\u003e1 x heat sink for voltage regulator\u003c\/li\u003e\n\u003cli\u003e1 x heat sink for ethernet chip\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cspan style=\"font-weight: bold;\"\u003eDocuments: \u003c\/span\u003eNone\u003c\/p\u003e\n\n\u003c\/div\u003e\n\n\u003cstyle\u003e\n.product-copy{line-height:1.7}\n.product-copy \u003e * + *{margin-top:1rem}\n.product-copy h2{margin:1.4em 0 .6em}\n.product-copy p{margin:0 0 1em}\n.product-copy ul,.product-copy ol{margin:0 0 1.2em 1.2em}\n.product-copy li{margin:.35em 0}\n.product-copy table{width:100%;border-collapse:collapse;margin:1.2em 0}\n.product-copy table th,\n.product-copy table td{border:1px solid #eee;padding:.6em .75em;text-align:left}\n.faq-list{margin:1.2rem 0 1.4rem}\n.faq{border:1px solid #e6e6e6;border-radius:12px;padding:.75rem 1rem;margin:.6rem 0;background:#fafafa}\n.faq summary{font-weight:600;cursor:pointer}\n@media (min-width:768px){ .product-copy{font-size:1.02rem} }\n\u003c\/style\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":45812633174305,"sku":"AG009","price":15.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/1491\/5617\/products\/heatsink-adhesive-aluminum-raspberry-pi-550.png?v=1689658010"},{"product_id":"raspberry-pi-b-2-3-acrylic-enclosure-kit-b","title":"Acrylic Case with Cooling Fan for Raspberry Pi 3","description":"\u003cdiv class=\"product-copy\"\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003eIf you prefer an unconfining Raspberry Pi enclosure, then this item is for you.
