After we already regarded few possible, alternative cooling for the Radeon a hd 5850, we go today into the second round. The Xigmatek Bifrost reached us - a new diagram map radiator with dual fan and Direct Heatpipe Contact technology.

The monster did not let itself install however on a Radeon hd 5850-Board and in such a way decided we that the Bifrost must prove its efficiency on a Radeon hd 5870-Board.

Holy terrible translation!

Result

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.

Lol, I know. Google's translate wasn't any better, unfortunately. At least the charts are readable, though.

Good example: The title of the article after being translated by google was "Xigmatek Bifrost meets radeon 5870 - low cooling possible."

Looks good. Wish I could get one. I hate my stock 4870 cooler. Thing is ridiculously hot.

In regards to the sone readings they got off of the cooler, am I to assume that the "3,1" is actually referring to 31dB?

measurment reading is in sones, not db's. so, 3,1 , or 3.1 in american is 41.1 db a weighted, but his only applies if it is a steady 1khz sine tone. There really is no way to convert sones to db for broad range noise. But you can figure about 41.1 anways just to get a comparison.
