So, my blue was looking to be down on power recently and as the PSU fan bearing was starting to squawk on startup; I thought I'd have a go at temp tuning when I was in there.

As I thought; the power of the 150mW CNI was down, to 117mW in fact.

After 5 hours of what appeared at first to be a waste of my life; she's now sitting at a solid 195mW with less noise too.

I was a bit disapointed not to see spectacular results as some have, but a worthwhile adventure in the end, recommended for anybody with lots of patience and some free time.
