I think Dupont pushes the temps to 90 F to get fermentation over in less than a week. Time in the fermenter is money.
For the Op. 4 weeks in primary is probably OK. I would not leave it there that long. With the high temps. I think you are tempting autolysis problems. High temps will degrade the yeast quicker.
Once fermentation is over, maintain high temp for a couple of days, and then you can bring back to room temp.
