It is a \u003cstrong\u003efactory-direct alternative\u003c\/strong\u003e to imported 8 W\/mK silicone gels — same single-component silicone formulation, same colour and consistency, manufactured and packed in China to avoid the import markup. The gel sits at the high end of the silicone-based range and is well-matched to dense ASIC hashboards like \u003cstrong\u003eAntminer S19 \/ S21 \/ S21 Pro \/ S21 XP \/ T21\u003c\/strong\u003e and \u003cstrong\u003eWhatsminer M30 \/ M50 \/ M60 series\u003c\/strong\u003e, where chip TDP and chip count put real demands on the thermal interface material.\u003c\/p\u003e\n\u003ch3\u003eWhy an 8 W\/mK Gel Instead of Cheaper 5-6 W\/mK Pastes\u003c\/h3\u003e\n\u003cp\u003eTraditional 5-6 W\/mK pastes work, but as ASIC chip TDPs climb past 25-30 W per chip, the thermal interface becomes a bottleneck. An 8 W\/mK gel reduces the temperature delta between the chip die and the heatsink base, which on a typical S21 series hashboard translates to \u003cstrong\u003e3-6 °C lower chip junction temperatures\u003c\/strong\u003e at full hash. The silicone base also has very low pump-out under thermal cycling, so the joint stays full over the life of the miner instead of drying out or migrating off the chip top — the failure mode that ages cheap pastes after a few months in production.\u003c\/p\u003e\n\u003ch3\u003eWhy China-Made Instead of Imported\u003c\/h3\u003e\n\u003cp\u003eImported 8 W\/mK silicone gels carry brand premium, customs duties and a longer logistics chain. This gel is manufactured in China to the same single-component silicone specification — \u003cstrong\u003esame 8.0 W\/mK conductivity, same -50 °C to +200 °C operating window, same 12-month shelf life\u003c\/strong\u003e — and shipped directly from our Shenzhen warehouse. For a repair shop running one or two pails per month, the cost gap compounds quickly, and supply lead time drops from weeks to days when stock is held locally.\u003c\/p\u003e\n\u003ch3\u003eApplication\u003c\/h3\u003e\n\u003cp\u003eClean each chip top and the matching heatsink contact area with isopropanol. Use a stencil sized for the target hashboard (Antminer S21, Whatsminer M50, etc.) to dispense an even bead onto each chip. Lower the heatsink straight down — do not slide — and clamp at the recommended torque. A 1kg pail is enough for roughly \u003cstrong\u003e40-60 hashboard rebuilds\u003c\/strong\u003e depending on chip count and stencil thickness. A 30cc syringe loaded from the pail, paired with a thermal gel gun, gives the cleanest dispense per chip on production benches.\u003c\/p\u003e\n\u003ch3\u003eStorage \u0026amp; Handling\u003c\/h3\u003e\n\u003cp\u003eKeep the pail sealed when not in use to preserve the 12-month shelf life. Store between 5 °C and 30 °C, away from direct sunlight. The single-component silicone does not require mixing — stir gently if any minor settling appears after long storage, then dispense directly into a syringe or stencil. The gel is non-conductive electrically and safe on standard hashboard substrates and heatsink coatings.\u003c\/p\u003e\n\u003ch4\u003e8 W\/mK Blue Thermal Gel Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eProduct\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e8.0 W\/mK Blue Silicone Thermal Gel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eColour\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBlue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eThermal Conductivity\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e8.0 W\/mK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eBase\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eSilicone, single component\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003ePail Weight\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e1 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e-50 °C to +200 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eShelf Life\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e12 months sealed (manufacturer spec)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eAntminer S19 \/ S21 \/ T21, Whatsminer M30 \/ M50 \/ M60, Avalon, Iceriver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCoverage\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003e~40–60 hashboards \/ kg (stencil-applied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eOrigin\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eMade in China (Shenzhen) — factory-direct\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated Thermal Materials \u0026amp; Application Tools\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/dowsil-8w-blue-thermal-gel-1kg-asic-miner-hashboards\"\u003eDOWSIL TC-3080 8W\/mK Blue Thermal Gel 1kg – Imported Reference\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/g18-hash-board-thermal-paste-1kg-5w-antminer-whatsminer-avalon\"\u003eG18 5W\/mK Thermal Paste 1kg – Antminer \/ Whatsminer \/ Avalon\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/whatsminer-thermal-grease-kl1040-white-1kg\"\u003eWhatsminer KL1040 Thermal Grease 4W\/mK – 1kg White\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/30cc-thermal-gel-gun-silicone-grease-dispenser-crypto-miner-maintenance\"\u003e30cc Thermal Gel Gun – Silicone Grease Dispenser\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eStocking a repair shop or mining farm? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for case-quantity pricing on the China-made 8 W\/mK blue thermal gel.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":45496180900019,"sku":null,"price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/china-made-8w-blue-thermal-gel-open-pail-texture.webp?v=1778202831","url":"https:\/\/lys-sz.com\/products\/china-made-8w-blue-silicone-thermal-gel-1kg-antminer-s21-hashboard","provider":"LYS Shenzhen","version":"1.0","type":"link"}
