The temperature sensor is not the ASIC chips, if the temp sensor is at 100C then your ASIC chips can be around 150C and most of your other components like capacitors and resistors, its strains all compontents and they will fail prematurely.
I really don't understand why you would run them at 100C and assume its perfectly ok.
I don't/haven't ran them at 100C continuously. Again, this was a brief test to prove they hash and at what speeds.
I just moved the units to ensure clear air flow and have the air conditioner on. In 40 minutes or so I'll take another temperature reading (along with hash rate).
The problem is you shown me you'd even let this go for even 1 sec. You say these hash fine, they dont really, you have HW at stock Freq and your hashrate is very low. This shows you've not taken care properly of the unit or are using a bad PSU.
My PSUs are fine. If you aren't interested, please stay out of my thread. Thank you.
I think you did not understand me. EITHER you have bad PSU or you ran the S5 too hot and they lost a significant portion of their hashrate.
Since you supposedly have fine PSU, it mean that your 10% hashrate lost is due to the improper way you've been running the S5s.
Good, i guess i can stay, then. I'm interested in cheap S5's. I think they're still a bit too high however, considering their clear damaged states. (10% hashrate loss at stock setting + HW)
If you care, Allinvain is selling fully functional and unabused S5's for probably 100$ea now (His asking price is 120$) or maybe even cheaper in bulk. His thread is just next to your's.
Only one is damaged. A board isn't working on it, and it hashes at half what it's supposed to. The other one works fine.
You've made a good point about the price, however. I'll let the entire package go for $200 even. $100 for the fully working miner, $50 for the half-hasher, $25 per PSU (You won't find a better price for those PSUs) and the fans I'll toss in just because.
I THINK I have the stock fans (which are loud as all hell) laying around here somewhere. I'll toss them in as well, but no promises.
