I'm going to give you something totally different, but easier to try to find. Check the seal around the plenum up top on all side. The fact that it comes on after it gets a little heat signals it could be that. You can try to isolate the noise by listening wyith your ear close all around the seal, but it becomes really easy if this is it, to find it with the mechanic's stethoscope. They are only $10 - $15 and will really help find this.

The correct fix is obvious, but if it's this type of leak you can seal it with another $10 or less of high temp tape. Push some electrical tape up against the leak, or better yet a small piece of high temp aluminum tape or self adhesive duct seal :-)

It could get you by for the summer.

I spent a lot of time and few dollars and had my alternator rebuilt to find out my noise was a plenum leak right above the alternator :-)
