Pretty sure you'll be fine, fan's don't use that much power to be fair.

I worked it out as just under where you're just over if it was me I would upgrade the PSU its worth noting these sites work the draw out as if the system is pulling at 100% computers don't always draw the same amount of power from the power supply all the time the drives go to sleep, CPU usage drops, fan speed could be slower if temps are down.

If you do cross it and the power supply detects an overload your PC could just shuts down honestly I think you will be fine.

Adding 2 fans isn't going to take you from under 500W to over 500W.

So if it's fine now, it will be fine with 2 more fans.

It would be worth knowing the make and model of the PSU you're using though, as if it's low quality you definitely won't want to add any more load.

Thanks for replying guys. Im only asking as im upgrading them to rgb fans so in my mind it might use alot more power? I probably will upgrade to a higher wattage evantually. This is my first build! Im still learning. Im using a EVGA 500w 100-W1-0500-K3.

Each fan should use less than 5W, so it will be a negligible difference really.

That said, with a 9600k and 1080Ti you could definitely be close to pulling 500W under load, so I would really be looking at a good quality replacement PSU asap, something in the 550-650W range would be fine.
