My wife told me the rug in the living room was starting to look dirty and she wanted to get it out of there, I said, OK........ She came home the next day and immediately said where the hell is the rug, I said it's in the garage, you said you wanted it gone. She went in the garage and came back laughing her butt off and of course called me an a zz hole

I have not taken temp readings, there is enough verification in the thread on the link I posted above.
My main concern was with the added compression and the EITMS kicking on very often when in stop and go traffic or stuck in traffic. I do not agree that these things should see temps high enough to go into the heat management mode.
Following installing the fans I intentionally tried to get the heat management mode to kick on, I couldn't get it to come on. Then I turned the fans off, let it sit idling and as always the hmm quickly kicked on, I turned the fans back on and in less than couple of minutes the hmm went off. That's what I was looking for and that's good enough for me. This alone tells me that it has to be running cooler pretty much all the time.
