[QUOTE="cidsamuth, post: 16358221, member: 110091"] The theme I hear over and over from critics is that the fans do help in traffic, but perhaps only a few degrees and not worth the expense. Allegedly, they hurt above 35 MPH. But, here is my problem with these "facts." What is clear to me with mine is how much they help IMMEDIATELY OFF IDLE. Explanation: When sitting and idling, your IATs obviously rise primarily because there is very little air being sucked into the intake and over the intercooler. No HE is going to help much there, no matter how cold it keeps the fluid temp. And frankly, the HE is getting no air at idle, so the fluid temp isn't going to be all that great anyway. But, with fans, they are keeping the HE fluid cooler at idle than it otherwise would be. So, the second you goose the throttle and start flooding air over the IC, the IAT2s are going to drop much quicker because the fluid circulating through the IC is colder. At least that's my theory, and it is backed by my anecdotal experience going from a small, fanless HE to the VMP triple. Admittedly, the VMP had a ton of advantages besides just the fans, so my theory is a hypothesis not backed by an "apples to apples" comparison. [/QUOTE]
