Mine gets hot as well - a gable roof with a vent on either end. No eaves venting so air flow is only north-south. The new reflective silver metal should help vs. the old asphalt shingles.
I asked on a different thread about adding a fan on one end controlled by a thermostat but never got a response.
This is the one I was looking at:
Cool Attic CX1500 Gable Mount Power Attic Ventilator with 2.6-Amp 60-Hz Motor and 14-Inch Blade

Sorry, I musta missed that one?
I like em' but not sure how effect they are since I have never tested it with any instruments. When its 120 up in there, every bit of air flow will help is my opinion. I always put those things, or power fan or vents in homes in general knowing every bit helps. I put them in my parent's home. They have high ceilings, almost 10' 1930's Spanish home. I remember, it was cold but relatively cool during the warm months. Once it got near 100, nothing would help. I stuffed a huge amount of insulation in the attic and installed two of those gable fans on a thermo switches set at medium setting. One to draw air, the other would push air through the attic with normal vents on other sides.
By doing so, I was able to reduce interior temp by about 8-10 degrees during summers. What made the huge difference was the new windows, I truly believe. At 85-90 degrees during summer, their AC doesn't come on until after 1-2pm. The house is much warmer too in the winter months. In the past 15 years, their ac has been set on auto at 79 degrees come April until October.
I forgot to mention, mount those fans on rubber or urethane of some type to dampen vibration. I have done it with and without and really notice no difference unless the house is dead quiet, I bearly notice them kicking on.
