Fermentation temperature for an IPA

I haven't found a global agreement on these topics. Let's suppose that the yeast is American (such as Safale US-05). Then:

Which is the ideal (primary) fermentation temperature for an IPA and why?
Which is the ideal temperature for an IPA placed in secondary with dry hopping and why?

My first brew was a Pale Ale and I used Safale US-05. From what I read, fermenting outside the range recommended by the manufacturer should give you some off flavors, but since my temperature controller hadn't arrived in time for my first brew, I fermented at room temperature ~25-26°C and it was fine.

I use Safale US-05 often and go with a temperature of 66-68 degrees. I keep a digital thermometer in my brew/fermentation bag and throw in a couple of small frozen water bottles. I check it about every 12 hours or so and once I get to 68 degrees I replace the bottles.

But as most have already said, that works for me.

Agreement with the two answers so far from EvilZymurgist and brewchez, but to address the dry hopping portion of the question: you should dry hop basically at fermentation temps, or, at least, not at cold-crash/serving temps, to maximize hop extraction.

There isn't an ideal temp for any of this. There is a recommended range offered by the manufacturer to help guide the end user towards a higher degree of success that something will ferment. As for US-05 yeast, I've heard of people using it at weird temps outside the "recommended" range and having success. But success for them may be different than success for you or me.

The ideal temp is what works for you. Some people may like to ferment warmer or cooler due to the flavors they get. As for dry hopping, its still a moving target dependent on preference. Some say cool, some say warmer.

Brewing can't be saddled into set numbers. Its about brewing an IPA a few times and seeing what works best for you.

Most Ales do well at 68°F primary, to limit phenols and undesirable esters made by yeast during growth phase.

Secondary can go up to the higher end of recommended temp of a strain since there isn't much left for yeast to feed on and it's at this time the yeast consume those byproducts made in primary. So the higher temp encourages yeast metabolism.

There is no adjustments needed for an IPA. It should be treated as any other Ale for ideal yeast conditions.

Us-05 has an ideal range of 59°F-71.6°F

Each yeast has its own esters, if you want to accentuate them, it is controlled by temp. Warmer generally gives more esters.
