Yes, 2 8R's in parallel also gives 4R, stupid of me, well forget the schematic, these will be bolted in a case from about 40cm x 20cm, 2U and 2 Papst ventilators, I hope that will do the trick. Yes, it was suspicious they were that cheap for 100w resistors. It's like EDavid said, the price for a real 100watt is about €200 to €300 at least on this side of the globe.
Hey guys, thanks for the tips here. You helped me a lot.
