EVGA GTX 980 Ti Hybrid Review
There’s nothing untowards going on here, through we can see there’s a ton of heat being carried up through the radiator’s tubes, stored in the reservoirs and then dissipated through the fin array. This indicates the radiator is working to efficiently disperse heat being output by the core and is nowhere near reaching its thermal capacity. It is also interesting to see the internal pump / block assembly radiating enough heat that the shroud heads up.
What you see below are the baseline idle dB(A) results attained for a relatively quiet open-case system (specs are in the Methodology section) sans GPU along with the attained results for each individual card in idle and load scenarios. The meter we use has been calibrated and is placed at seated ear-level exactly 12” away from the GPU’s fan. For the load scenarios, Hitman Absolution is used in order to generate a constant load on the GPU(s) over the course of 15 minutes.
Unlike the Sea Hawk which uses a single fan that’s tied directly to the motherboard’s fan headers and can thus have its RPMs modified to a user’s preference, EVGA decided to have fan speeds linked to water temperatures. As such, there’s no user involvement.
In our testing EVGA’s approach seemed to pay off since acoustics aren’t noticeably higher than MSI’s solution despite boasting substantially lower temperatures. The fan increased its RPMs in a very linear fashion as well and its sound never intruded into the environment. For the record, there wasn’t a hint of inductor whine either.
System Power Consumption
For this test we hooked up our power supply to a UPM power meter that will log the power consumption of the whole system twice every second. In order to stress the GPU as much as possible we used 15 minutes of Unigine Valley running on a loop while letting the card sit at a stable Windows desktop for 15 minutes to determine the peak idle power consumption.
With lower temperatures and clock speeds than the Sea Hawk, power consumption is slightly lower. However, despite its reduced clock speeds in comparison to other cards in the chart above, the Hybrid actually consumes more power due to its integrated water cooling pump and large fan.
