PCIe extenders arrived yesterday and my "Michael Schumacher" oil radiator arrived this morning.
I should have read the specs more carefully, it clearly said 18.5cm so I only have myself to blame, but holding it in my hand, that is MUCH smaller than I thought by looking at the photograph. Its exactly the size 2 90mm fans next to each other, so smaller (but thicker) than your typical highend PC watercooling radiator. Somehow I pictured it at least twice that size.
Still, with its relative thickness and extremely fine grating and Im sure its more than capable of dissipating the heat of a few gpus, at least when submerged in cool water. Its actually kinda neat, and I cant believe how light it is. It came with a certificate of authenticity too, so thats at least an extra 100 MH/s
I also picked up the cheapest 1200L/H aquarium pump I could find (15 euro). I dont expect it to last, Im sure it will overheat and fail, I just want to see what happens regarding flow rate and temperatures when it must pump oil so I get a rough idea of sizing the actual pump. 1200 L/H turns out to be a serious amount of water for such a tiny pump, wow, but then it doesnt have to cope with thicker oil yet, nor any resistance from long tubes and the radiator, so we'll see what that gives.
Now Im waiting for some epoxy raisin to arrive to coat the foam, I need to pick up some tubing and with some luck Ill have a test setup running this weekend, although it will be "dry" for now, cooling the oil with just fans. Its freezing -11C outside, so my pond pumps are shut down. Should the oil heat up too much (which I highly doubt) I can always submerge the radiator in a bucket of water for testing.
question: have any watercooling guys here measured water temperatures at the inlet and outlet of their radiator? Can you give me a ball park guestimate?
