      Pre-order miner delivery times depend on the factory schedule. Estimated delivery dates are provided on the order page, but delays may occur due to production issues.

      Shipments are processed on a first-paid, first-shipped basis. Once full payment is received, we aim to ship as quickly as possible. Payments via wire transfer (T/T) may take 3-7 business days to verify, while cryptocurrency payments typically take a few hours to 1 business day.

      International shipping usually takes 5-8 business days, with remote locations potentially requiring 8-10 days.

      *All sales are final and non-refundable. Please understand, this is an industry standard.

      For new, factory-sealed miners, the warranty is typically 12 months or 6 months, depending on the factory's policy, starting from the production date.

      The company is not responsible for issues resulting from failure to follow the provided instructions, specifications, or alterations to the product.

      For used mining machines, there is no warranty or after-sales service; however, before shipment, we will provide mining machine testing videos to ensure you understand its performance. Once you confirm acceptance, we will proceed with full communication and arrange shipment.

      How to Choose the Right Liquid Cooling Equipment?

      Consider your hash rate, miner compatibility, available space, and future scalability when selecting liquid cooling.

      Not sure what to choose? Contact us for a custom solution!

      Is Liquid Cooling Noisy?

      Liquid cooling systems are generally quiet due to reduced fan usage, making them ideal for home mining setups or office environments. However, under high load, noise from the water pump may become noticeable.

      Do I Need Specific Coolant for Liquid Cooling?

      Most liquid cooling systems require specialized coolant for optimal heat transfer and low corrosion. You can either purchase it directly from us or buy coolant from a recommended brand locally.

      Is Installing a Liquid Cooling System Complicated?

      Installation is straightforward but requires correct connection and coolant filling. Detailed guides are provided to help with setup. We also offer remote supervision through shared chats or video calls to assist during installation if you need it.

      For larger projects upon individual agreement, on-site installation services are possible.

      Does Liquid Cooling Need Regular Maintenance?

      Yes, regular maintenance is necessary, such as cleaning radiators, pumps, and pipes to avoid dust or scale buildup. You may also need to change the coolant over time to maintain efficient cooling.

      Can My Liquid Cooling Equipment Be Used for Heating?

      Yes, some models can recover heat for purposes like radiators, floor heating, hot water, or even heating a pool—allowing you to heat and mine at the same time!

      Can I Get a Discount?

      We offer special discounts periodically. Stay updated by following our website or joining our Telegram group (https://t.me/apextomining).

      Join our Telegram group for early access to exclusive offers and discounts!
