Thanks! I connected the 2 PCIe cables, up to now it seems to work great. I'll do a temperature check tomorrow.

Now I have to make this fanmod before the wife starts to beat me up.... :p

i did not dare to run it at default for more than 12 hr...
Everyone seem to be particularly affected by the S5 default fan sound. You want to stay as far away as possible.
what's your mod?

I replaced the loud stock fan by two 120mm fans I had in spare. The fans are in push-pull configuration and powered directly from the PSU (constant speed).
It makes my S5 really quiet, about the same as my desktop computer. But I had to downclock to 250MHz (~800GH/s) to keep the temp below 60°C.

So at this point I loose 30% of hashing power to reach an acceptable sound level..
Next step I'll try more powerful fans with the "fan shroud" trick mentioned by dog1965 (https://bitcointalk.org/index.php?topic=908494.msg10250546#msg10250546

I also noticed a big spread between the 2 temp sensors... Any idea what it could be??
