Hi everbody!
thx for the quick responses, i've only been a memeber for 30min and i already love this forum!
the specific graphics card is a: GTX760-DC2OC-2GD5.
of course it tried the EK coolingconfigurator but they don't have any blocks that will fit my card.
the 670 and 680 have tottaly different designs and i checked but they wont work
still thx for all the responses, but if anybody seems to remember the charts i was talking about or the company who makes them, please leave a response!
