I'm still making our own version that will probably be ready in 2 to 3 days. I'm also working on waterblock(will be available for US in about 20 days or less). After assembly I will do some tests to make sure all is well.
Hi Lucko
Will this waterblock be available in time for group buy batch 1?
and what size radiator will it need?
and how many will we be able to chain together?
final question, will it have a cost impact?
GB batch 1. If prototype works yes. I don't have 16 chips(only 7 samples) so I can't test... But we can make some agreement to host boards if needed...
No idea about size, depends on a radiator. It is about 200W per board so that is the guideline...
Flow would probably be the factor how many you can chain... So again this is the question...
Custom cooler is in the price of a board if you replace it with WB there will probably be some difference but I need to see cost... We are still at prototype stage... Probably you will see custom cooler pictures tomorrow(will send one to form ASAP to test)... WB will be available after that but no idea how soon at the moment. Need to test for leakage. If there will be time I will do my best to send one to form to test it with 16 chips...
But if you use WB you need to add some fans(not hi power really low speed) to get some air flow over power modules... I was looking into a way to cool them with WB but I can't do it at low cost...
