GoKawiilReddit user finds abandoned mining rig with 12 Zotac RTX 3070 GPUs intact
A Reddit user acquired two old cryptocurrency mining rigs left in a basement, containing a total of 12 Zotac RTX 3070 graphics cards along with an MSI motherboard, a 1000W power supply, RAM and SSDs. Despite years of storage, the hardware showed only minor wear, including some silicone bleeding from aging thermal pads, but appeared largely salvageable.
GoKawiil's interpretation of the reporting above, not reported fact.
The find highlights that GPUs used in mining operations aren't automatically degraded, since many rigs ran at reduced voltages and temperatures that can actually preserve hardware longevity. With used GPU prices still relevant for budget gamers, such discoveries show that secondhand mining cards can be a viable, low-risk option after basic maintenance.
- 12 Zotac RTX 3070 GPUs were found in old mining rigs after years in storage.
- The cards showed only minor issues like silicone bleeding from degraded thermal pads.
- Mining GPUs often run at lower power and heat levels, which can help preserve their condition.
Arctic MX-6 Thermal Paste — Reviving old mining GPUs starts with fresh thermal interface material, and Arctic's MX-6 is a go-to non-conductive paste for repasting a GPU die after cleaning off dried-out old compound. Pair it with isopropyl alcohol and new thermal pads and those basement-find RTX 3070s can run cool again.
