Using these in mining cooling equipment under pretty rough conditions. They’ve been running for a month now and are super stable.

Really good quality, the ASME SA249 standard is the real deal. I was worried about the fins getting crushed during the long trip, but the packaging was top-notch—not a single one was bent.
