Sytrin KuFormula VF1 Plus graphics card cooler
 

If noise is no concern, the KuFormula VF1 Plus is certainly a most capable heatsink — at full speed (an ear-splitting 42 dBA@1m) it cooled our test card better than any other cooler we've tested, by a small margin. Unfortunately, its noise character is undesirable to most users, and the fan's noise character was far from good even when undervolted.

With noise taken into account, it falls from being the best to being merely good. It is far off the pace of the VF900, but manages to pull a respectable second-place, even with the significant drop in cooling efficiency when the fan is turned down. And, with the fan bumped up just a little, it can almost match the VF900 while still maintaining a noise level that is acceptable for a system where noise is not the first priority.
