Strato thank you for sharing this idea of vertical mounting. I just tried it out the last few hours and had some interesting results:
1. Avg. temps are the same, but before the S5 was laying on the floor, now it is 1m higher, so the room temperature there is 1 or 2 degrees higher for sure - so the cooling of the unit must have improved
2. One blade was always at least 5 or 6 degrees hotter before, now it is only 2 or 3 degrees, sometimes even the same temps
3. Hashrate has only slightly improved (still waiting for long term results)
4. HW error rate is down appr. 15%
I will continue with the vertical setup and see where it goes.
Thanks again.
