Innocent White: KFA2/Galax GTX 1070 Ti Hall of Fame under review

What is white, slightly overweight and even really fast within the framework of their genes? No, we are not writing about a full Snow White on Speed, but the Galax GeForce GTX 1070 Ti Hall of Fame, which is held in Europe for trademark reasons. KFA2/Galax uses a modified GTX 1070 Hall of Fame board for the GTX 1070 Ti Hall of Fame, but with slightly improved assembly. This, in turn, is not a cost-down, but also takes into account objections from our previous reviews similar to... Important preliminary remark We had already mentioned it at the beginning that almost exclusively the resulting boost clock rates of each GTX 1070 Ti determine the final performance and thus the so-called GPU lottery and not the manufacturer and model....

Cooling system and backplate

Of course, the generated waste heat is directly related to the recorded power, for which the cooling solution is responsible for optimum dissipation. This rather massive cooling system relies on a large lamella heat sink and a plate made of cast aluminium for stabilizing the structure and cooling of some components, which must be cooled by the air flow.

The cooling for voltage converters and memory must be used, as in the case of e.g. MSI and EVGA, it is precisely this assembly and Loosen the cooling frame between the radiator and the board, which we also like to call a sandwich plate. However, this concept is still justifiable in these areas of performance.

The used and blackened inside backplate is only used for the optics and stabilization of the radiator structure to the same extent, but not for passive cooling, which we regret a little.

Cooling system at a glance
Type of cooler:	Air
Heatsink:	Copper heat sink for the GPU
Cooling fins:	Aluminum, vertical alignment related
Heatpipes	3x 8 mm and 1x 6 mm, copper composite, nickel-plated
VRM cooling:	GPU and memory VRM via mounting frame
RAM cooling	via mounting frame and indirectly via the heatsink
Fan:	3x 9 cm fan modules 9 rotor blades each no semi-passive regulation
Backplate	Aluminum, blackened no cooling function

The cooler itself is a huge and above all heavyweight Bolide, whose copper heat sink feeds a total of four 8 mm and a 6 mm heatpipe made of composite material with the absorbed GPU waste heat.

The three 90 mm fans used, with their 9, fairly steeply employed rotor blades per fan, are designed for throughput rather than for pure uniform static pressure. However, we will have to come back to these fans later, when it comes to fan control and speeds, because there is some need for clarification.

Fan curves and noise emission ("volume")

The fan curves show that KFA2/Galax, like Zotac before it, does not require a passive mode, i.e. a fan shutdown. With approx. However, 1060 rpm, the fans are still, almost inaudible, at approx. 32.5 dB(A). You can leave it that way, even if it is surprising at first. Only some lower frequency fractions interfere, if at all. Under load, the whole thing remains even in the closed housing under 1500 rpm, which is very good and also quite quiet.

The whole thing doesn't look much different with the stress test. In summary, the card with the three fans can't be a quiet wallflower, but it still remains quiet enough to play at the front of the hall of the best.

The card has reserves to make the fans rotate lower. It would definitely work, but then cost at least one boost step.

Measurements for fans and noise emission
Fan speeds Open Benchtable Maximum	1419 rpm
Fan speeds Open Benchtable Average	1365 rpm
Fan Speeds Closed Case Maximum	1485 rpm
Fan Speeds Closed Case Average	1380 rpm
Noise emission (air) Maximum	35.2 dB(A)
Noise Emission (Air) Average	34.5 dB(A)
Noise Emission (Air) Idle	<32.5 dB(A)
Sound characteristic / Hearing impression	light engine noise< 1 Hz moderate air/demolition noise hardly or No voltage transformer noises

To illustrate our subjective audio impression once again, we now have a high-resolution graphic with the complete frequency spectrum of our laboratory measurement:

The 35.3 dB(A) is good and more than acceptable for such a map and the measured temperatures. There would even be significant reserves down, which could have a bit of an impact on the boost steps, depending on the housing ventilation.
