The fan circuit is a high current circuit. The CONNECTIONS in any high current circuit MUST be tight!
Pull apart one of those old damaged relays and extract a good undamaged MALE PIN.
Use the male pin to conduct a PIN "PUSH/PULL TEST.
Insert the male pin into the female socket pins. When you insert and extract the pin, there should be very firm grip on the male pin.
If the male pin is SLOPPY and has a loose fit,,, THATS YOUR ISSUE! The loose / poor fit causes heating and high heat at that connection.

With my dual core radiator and ls2 water pump I never see over 215 in 120 degree desert heat in stop and go traffic. This is with the stock thermostat as well.
This is also with a 25% underdrive pulley.
The stock radiator is garbage on these cars, on top of that it catches all sorts of debris from the roadway. If it bugs you the way it bugged me swap out those two items and you'll never have to look at your temp gauge again.

My car spent it's entire life in Socal. There was enough dead pine needles and such in my stock radiator to start a small wildfire lol. Not to mention underdriving the waterpump doesn't help matters any. Ls2 pump moves more Gpm to compensate for the underdrive with less rotating mass to boot

And if they are a tight fit? Now what? Short in one of the fan wires, maybe??? They don't blow right away as if its a dead short... I drove it for like 7-8 days before the fans quit and I checked the relays to find them burnt...

Sounds to me like you might have a bad motor that is eventually drawing too much juice and frying the relay... just needs the right conditions to do it...I would think a specific pin that is getting hot can give you a clue to where or why it's blowing...someone said there should be a diagram showing what pins do what or go where on the side of the relay...
Still could be a short that just didn't make contact for a few days and then BAM it made contact and blew your relay...
Others WAY smarter than me will help you find it
But, I like to take a shot at what I think it might be and every now and then even a blind squirrel finds a nut...
Really I enjoy learning and one of the best ways for me to remember is to give my opinion and then see if it was correct or what else I have to learn...

if it's burned that bad the fuse box and connector underneath it are also likely damaged... I had an issue similar to yours a year or so ago, the ground to one of the relays was fried but was not visible on the top... as soon as I removed the fuse box it was pretty obvious
... I replaced the fuse box, repinned a new connector, built a new ground wire, and it has been fine since
hard to see but if you look towards the top far left side the second pin down is fried
along with the connector

How did you get the top off, does it just snap on some how? As I look at it it appears to have all on the wire attached from the bottom side and looks to be one piece. It's 2 pieces?

yeah you have to remove the cover around the side and then there are 4 connectors on the bottom that you have to remove and then the fuse box will come out... the pic I posted above is of the bottom side of the box, here's what the bottom will look like with the connectors installed (ignore the red circle)

yep
... it's really not a bad job at all, I took pics and had a connector pinout in front of me that I triple checked before firing it back up
