Holy terrible translation!
Xigmatek did not build a qualtitativ high-quality radiator for efficient diagram map models in principle with the Bifrost VD1065 - a question. Scold must the manufacturer within the range of the volume fetch itself and this by right, because within the range of 32 railways (A) does not lie one within quiet ranges and straight that is also one point, why users after alternative cooling solutions look out to hold.
Here Xigmatek should have packed either an exhaust price increase in otherwise very good scope of supply, or at least tension adapters on 5 and 7 V. Since these are missing, one disqualifiziert oneself practically.
The question regarding an alternative cooling of a Radeon hp 5870 is to be answered with. On full number of revolutions the Bifrost is absolutely in the layer such a conversion sufficiently quieter to cool - in all Lastbereichen thereby however partly only somewhat, than the reference radiator does this.
