The EK testbench

Loop:
EK-FC7970 prototype block
360 RAD
3x Yate Loons D12SL
2m 12mm ID tubing (1/2″)
D5 Vario + EK X-TOP V2
EK-RES X2 250 Advanced
EK-12mm High Flow fittings

Furmark ran for almost five hours!
Cards running at stock volts yield the following results:
Tgpumax = 41°C
Th2omax = 30.7°C
—
dTmax = 10.3°C = ~ 10°C

Overclocking the card to 1125/1500MHz (GPU/RAM respectively) @ 1.250V yields:
Tgpumax = 42°C
Th2omax = 31.1°C
—
dTmax = 9.9°C = ~ 10°C
