Figured you 1st gen people might know since the G35 and 1st gen FX share the same engine. I'm getting two different weird noises.

1. The first noise I'm getting is a whining humming noise from the engine when it's warm and has been driven:

2. The second noise is a chirping buzzing sound on cold start from the engine:

By the way I tried asking on G35driver an that website is horrible. Everyone shit talks each other and doesn't help anyone. No replies at all. One more reason I love IS!

For #1, electric fan was my first guess too. My e-fan conversion is very loud, compared to other fans from other 45s. I guess every fan is a little different, but this sounds normal to me. For #2, it's hard to decipher as well, but seems normal to me on a cold start. Overall in both videos, I don't notice anything really out of the ordinary. Maybe your used to how your FX runs and sounds and not used to the single intake VQ?

I notice a slight wobble in the pulley maybe that's it? So an electric fan is suppose to be loud? How come my 2nd gen FX isn't loud or does that even use an e fan? Sorry for my ignorance lol.

One more question, when I'm sitting at a stop and I accelerate I hear a really loud rattle from under the car maybe from the front. Any ideas?
