nope, you do not need cool temps for flowers

Believe what you want bro. It is on page 138, paragraph 2 (Temperature Requirements).

same to you bro.
After all we are after the same thing: to get our orchids to flower as much as possible so here is an extract from his other book on flowering tips:

Not Enough Difference between
Day and Night Temperatures
The most common reason that orchids don’t bloom indoors is that
the environment doesn’t have enough of a change in temperature
between day and night. In orchids’ natural habitats, evening temperatures are at least 10°F to 15°F lower than the daytime temperatures. This temperature difference triggers the orchids to start
developing flowers. In many home environments, the temperature
doesn’t vary much between day and night.
Get yourself a maximum-minimum thermometer (see Chapter 3)
and place it in your growing room. This thermometer will tell you
if you need to move the plant somewhere cooler in the evening,
like closer to the window.
If you summer your orchids outdoors during the summer (see
Chapter 5), you’ll easily be able to provide this temperature difference. The temperature in my orchid summering area outdoors drops in the evening at least 15°F and sometimes 20°F or
more during late summer and early fall.

Orchids or phalaenopsis?

I'm not interested in musings on generalised care which you criticized yourself in a previous post. His book on phals is clear which you have not read.

ok point well taken, so lets forget frowine, I mentioned there are endless other articles.

Take this one then, there is no question temperatures are very important, it's been documented too much to question it imo:
