So since getting my Blue Yeti, things have been tough but I've managed alright. I got this when I really didn't understand how recording works and now that I've spent time researching and playing around, I've managed to get a few auditions and have a lot of fun. Unfortunately, I just started having this problem today where this odd humming noise has appeared on all my recordings. I understand that it's because the Yeti is and USB mic, but I've never had this issue until now and I've managed to edit out all other types of noise except for this. Results from online saying that I need to reduce the noise on Audacity, keep switching the ports around, and turning the gain on the mic all the way up have slightly muffled it at best. I'm kind of at a loss right now and I have a project I need to record for this week so any help you can give me will be greatly appreciated. I have included two samples below, one as just the sound and one with me speaking.

I used to use a Blue Yeti for a few years and the one thing I can say is that I've heard that kind of background noise before when I recorded on it, I don't know why it suddenly started appearing on your end, but what I typically did was use the Noise Removal tool in Audacity to select the white noise and then cancel it out, so even if the white noise was appearing, I never heard it on the finished product. Have you considered trying that tool and then seeing what the result sounds like?

Been doing that for hours and it still persists. For some reason, my version only has "Noise Reducer" instead of Removal, though I'm not sure if it makes that huge of a difference. Like I take a sample of the audio of just that, go through the process of identifying it, and then run the reducer on the entire track. I take out some other sounds that appear, but this hum is always constant.
Despite that, I've been doing some more research and I think the sound is my fans trying to cool down my laptop from being under a blanket fort for so long. It makes sense to me as of why I haven't heard this before until now, though I can only control the temperature of my room so much without turning on fans and opening windows. I'm going to shut my laptop down for a bit and make some stands for it, but I won't know the results for a while so I'm still open to ideas.

See if there's a way to isolate yourself from your laptop. It may not be convenient to record that way, but it's worth testing to see if it's your cooling fan that's doing this. If you're recording under a blanket, try putting your laptop some distance from you and run the mic and cord up under the blanket where you are. If the hum decreases, chances are it's your cooling fan.

The culprit definitely seems to be the cooling fan. I had my laptop shut down for the night, I aired out my desk, and I found caps to keep my laptop off the surface. The noise hasn't been produced today and I'' able to filter out the normal static that occurs. I guess it really is the little things.

I do think it would be the fan, and I'm also using a Blue Yeti mic. It still gets minimal noise when I'm trying to get a silent zone to use for Noise Reducer (It was Removal in the old versions, so you're fine). Figuring out how much to reduce it is part of my problem, but it is a very sensitive microphone.
...And your problem's already been cleared up before I read the last post. Oops. I will say that if you unhook the power cable from the laptop, it generally won't run as hot since there won't be as many auto processes running then. It makes sense this time of the year if you're in the U.S. It's been hot as heck here lately.

Yeah, heat has been building up quickly on my laptop and my room is one of the hottest in the house. It started going off again after being inside for a hour so I had to bring in a stool and set it there while I recorded in the blanket fort. At least I know now this will only be an issue until the fall.

At least I know now this will only be an issue until the fall. If you don't have one in there already, you should get a thermometer so you can make sure the room doesn't become too hot. When we think of heat stroke, we think of being under the blazing sun -- but if you're in ANY sort of closed-up space and it's the "hottest in the house" and quickly overheating your laptop just from the room temperature, you want to make sure you don't overheat and get sick, especially if you're in there for long stretches of time. Humans don't really have computer fans installed.
Also, remember to drink plenty of water.

I use one of these occasionally for travel and had the same issue---it was driving me crazy, and the hum was so loud that trying to take care of it with noise reduction made the voice sound tinny and filtered.
I found out that it was because the mic was set up on a wooden desk and the desk was causing a weird reverberation to come through in the recordings. I put a blanket under the mic and that stopped the problem. This seems to be a bit of a design flaw with the product, as I've never had issues with other desktop-style mics or stands doing this.

A standard rubber-and-cloth mouse pad is a good way to isolate a mic-stand from a table.
