I recently had a small accident where a glass of water spilled on my desk, and some dripped onto my PC case. It seems like a bit got through the cooling vents, but it was mainly on the case itself. I've already removed the panels and wiped up what I could find. There were just a couple of tiny drops on the motherboard that I dried off. Given the circumstances, how necessary is it to completely disassemble my PC to check for moisture? Can I just point a fan at it for a few days instead? I'm a bit hesitant to take everything apart since I'm not experienced with building PCs, and I didn't shut it off immediately when the spill happened.

I'd recommend being cautious. If it were my machine and I was okay with potentially replacing parts, I'd just let the fan do its thing. It should help evaporate the moisture.
If you can just let it air dry with a fan, that might be enough. No need to completely dismantle everything unless you're really worried about moisture.
There's definitely a risk of shorts or damage if water bridges contacts. Make sure to act quickly since residue from the water could cause corrosion. While a complete teardown is the safest method, it's really up to you to judge how serious the situation is.
Ideally, disassembling the PC completely is the best route. But if that’s not an option for you, just keep your fingers crossed that nothing shorted out. Bob Ross would say to learn from this 'happy accident' and maybe practice assembling in the future!
Make sure to open the case and let it dry thoroughly. Once it's completely dry, it should be safe to turn back on.
When my brother spilled water on his setup, we took out the GPU and RAM, then set a box fan up facing the open case for a couple of days. That worked like a charm! If you have some compressed air, that could really help speed things up too.
I didn’t notice water causing any issues when I wiped it. The drops were really minimal."
