The temperature differences between those measure points were pretty much what I had gathered on numerous forums about this very same subject. However it is always great to have evidence, great job nicozeg!
IMO cooling the base of the HDD is waste of time because even the hottest spot is only 1.4C hotter than the sides, not worth the extra effort required to construct a fitting waterblock there.
So: If you're planning to keep the HDD's in the 3.5" rack, then I would go for the top cooling as it can fit the rack and is also more than efficient enough to cool down the HDD and if you're using 5.25" spots or making a sound dampening box for the HDD, I'd go for side cooling as then the required space isn't an issue.
