The hedgehog is highly effected by fan changes. A panaflo fan would work, but expect the hedgehog with this fan to perform slighly worse than an alpha/fop with the panaflo fan. This is with the average, mediocre quality hedgehog(most are mediocre'ly made).
If you happen to get lucky and get one like the anandtech one(like with perfectly soldered in pins), then you'll probalby outperform anything else equipped with the same fan. Depends on luck of the draw.
