A low-profile cooler like the KT-27 at \u003cstrong\u003e27mm\u003c\/strong\u003e fits within these space-constrained environments while still providing active PWM-controlled cooling. If your build uses a standard mid-tower case, a taller tower cooler will generally offer better thermal performance for the same CPU.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eWhat is the copper-core base design and why does it matter?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\n        \u003cp\u003eThe KT-27 uses a \u003cstrong\u003ecopper-core insert\u003c\/strong\u003e embedded in the aluminum base plate. Copper has approximately 4× higher thermal conductivity than aluminum, so the copper core rapidly draws heat away from the CPU heat spreader and transfers it into the surrounding aluminum fin structure. This hybrid design improves heat dissipation compared to a pure aluminum base — particularly important in a low-profile cooler where fin surface area is limited by height constraints.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-cta\"\u003e\n    🛒 Add to cart above to get started.\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"Default Title","offer_id":52381200580882,"sku":"HKTBSMA770001","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/01_f4365ace-cb56-462b-ab53-0e16b5dc12d5.jpg?v=1781599870","url":"https:\/\/homediyer.com\/products\/sktc-kt27-low-profile-cpu-cooler-27mm-htpc-intel-lga115x","provider":"HomeDIYer","version":"1.0","type":"link"}
