sounds similar to a case i had before sadly i havent seen this video at the time of its upload but most likely the PSU wires are in the Fans way what i had to do was using a thin stick to push all the wires toward the inside away from the fans and thats how i got rid of it, yes if ignored it and it eventually cut through the wire things would not be fun ong
A one your your fans probably burned out a magnet in its motor causing it to spin unbalanced and making that noise or a steam of hair got caught in a fan
Thats not a grinding noise ya dunce. One of your fans is dirty/ misbalanced (due to the dirt/ debris in it). If its a new pc listen close, figure out which fan it is, call the manufacturer and get them to send you a replacement for the faulty one. If it isnt new and suddenly started making that noise, you need to learn how to clean you damn pc and stop neglecting your own property.
I have the exact same prebuild pc but i have upgraded it im actually currently heading to a best buy but i aint sure if a nzxt water cooling 3 fan will fit
Thats nothing to worry about. This is the noise i hear nearly every day in my work place, usualy just a dodgy fan bearing or a fan catching on a wire. If this is a legit video, id suggest unscrewing your gpu, taking it apart, give it a clean and make sure no wires are in a place where either of the gpu fans can catch them. If its a dodgy bearing, stop the fan from spinning and the noise will stop. Then either disconnect it and run it with one gpu fan working, or if you can afford to do so, jus t replace the gpu.
