so Test Results with the conventional four blade fan.

In a nutshell, no change, no difference than with the flex fan.

Cruising around the wind blows at the front of the truck so with either fan the temp gauge reads in the mid 175*s, but that's to be expected as the air overcomes the fans ability, I just wanted to level set

Now, in Park or in Neutral the truck is fine it will idle at 800 RPM in the low 180*s F, same with both type of fans

And in Drive or in Reverse with my foot on the brake (the RPMs drop to 600) the temp starts climbing, it will reach mid 195*s in five minutes and slowly keep creeping up above 200* eventually (about ten minutes later) again same with both fans

So I shift back to Park and watch the temps immediately start to drop, the gauge will return back down to the mid 185* or so, again same with both types of fans

just wanted to report that
