When I wake up and switch my PC on, it's really loud whilst booting, then around the time explorer launches in windows, it'll go quiet again.

If I reset / power off and back on it isn't loud. It's only loud really once a day.
If I turn off and back on BEFORE it boots into windows, it's still loud. So something in windows quiets/slows it down again.

It sounds like the fan is spinning really fast. I went into the BIOS and there's no fan controller, just a minimum (set to 200 RPM) and a number that showed the RPM, it was on 2000 when I looked, then it went higher and higher, I exited the bios when it was on 2500 RPM.

I know some GPU fans will go up to 100% on start-up for some reason or another, it may be completely normal.

Well, have you tried dusting out the CPU cooler?

I would say that this would be a solution if the CPU fan started out slow but then went faster due to overheating issues.

I've had a computer in the past that did this and I had a 4870 gpu do this at boot up. My guess is that it's a calibration test to make sure the fan can reach 100%. However I have no idea why it would start doing this routinely out of the blue. Sounds like some sort of update may have something to do with it.

My laptop does this sometimes, usually after heavy use and then immediately putting it to sleep. I'd assumed that when it started to boot it still had the temp reading from before I put it to sleep and that the reading wasn't updated until I was back into windows.

My stock cooler did this everytime I booted, I figured it was normal. The temps read fine, everything was good. Of course, my cpu's an i5, so it could be totally different. And the fact that it only happened a week ago...might be dust. Or heat.
