I think I figured out the problem, it was switching pools like crazy (I had the same pool 3 times in the cases)...but shouldn't it stop consuming while switching, and the end result shouldn't it be the same? Also it was mining on very low difficulty from what I could see, but the rejects were still low...Anyways, put a version that is 2 releases back and it works now, it stopped jumping around, and shows OK hashrate (not the best but acceptable). The bad thing now is that I can't spin down the rpm on the fans...so no way to keep it in the house.
