While Speedfan is a great program, all of these 3rd party monitoring programs occasionally have problems putting the correct sensor to label.
If me, I would buy a new fan - a quieter one. If yours is so noisy it is objectionable, the bearings may be going bad. And I would get the largest fan your case supports. Note the problem with slowing the fan speed down to control noise is you then reduce the cooling capability of the fan. So watch your temps. Noise is better than heat.

Not all motherboard fan headers provide fan monitoring or control. Many just supply power. And not all fans support monitoring and/or speed control either.

It was a fan I pillaged out of an old pc tbh, which I'm sure it didn't make the kind of noise it makes now! It has dropped my temps by about 5 degrees so I'll put up with the noise for now until I can get the funds to get a new'un.
Cheers.
Ps out of interest, does the fact I'm using only 3 pins and not the full 4 make any difference to anything?

That could be for a number of reasons. If your voltage is bit high (or it was a bit low before) it may be running faster now. Also, the case plays can big a role in noise suppression as does the mounting location.I'm sure it didn't make the kind of noise it makes now!

Actually fans only need 2 wires to spin. If the fan supports monitoring, it uses 3. Never four - though many use the 4-pin Molex connector.
It actually has yellow, black, green and blue wires. The wire in the unused pin is blue.

the thing i learnt today? if it has four leads/pins, its for a reason so dont use a 3 pin extension!
