had some investigation on watercooling on R290 cards with full waterblock in comparision of airflow cooling. Like to exchange on power consumption reductions on Linux, any proposals are wellcome.
Found powersavings just occure on low temperature. This means up to 40W for a single R9 290.
Test 2
• 730W power supply
• 1x R290 Saphire watercooled @44°C 0,76MH/s
• 1x R290 Gigabyte aircooled @85°C, fan @65% 0,82MH/s
Result-> 686W
Test 3
• 730W power supply
• 1x R290 Saphire watercooled @51°C 0,76MH/s
• 1x R290 Gigabyte watercooled @53°C 0,82MH/s
Result-> 648W
Test 4
• 730W power supply
• 1x R290 Saphire watercooled @42°C 0,76MH/s
• 1x R290 Gigabyte watercooled @43°C 0,82MH/s
Result-> 628W
