Are you sure the noise is coming from the processor fan?

Anyway from the video sound it's clear that something is not quite right with a fan. Could you try removing the fan and the processor and reattach it after a good cleaning, is possible with a handy vacuum cleaner. Also make sure nothing is stuck between the fan blades.

must be from processor fan as the case fan over the PSU got stuck and the processor fan was the only one running at time of video
both fans now run just i get that noise on start up for a few seconds
will try your suggestion tomorrow morning
and see how it works out if it comes to it new fan and heatsink are relativly cheap

I would suggest that if the cleaning is not working. A broken fan may leads to a fried processor.

use speedfan and note down thee temperatures. See if any hardware is overheating.

Don't waste your money. I have the exact thing happening to me and its to do with the fan going beyond its own rated RPM's until it drops down to its actual speed during its own computer startup process during POST till it makes it into the Windows Logo everything goes fine. The reason to this is because theirs no dampening rubber fixes to stop the very fast spinning fan from rattling against the metal heatsink. If I were you, shutdown the computer and gently remove the processors HSF (heatsink Fan) and get a appropriate screwdriver for the ***** thats allocated in the fan to secure it to the heatsink and tighten the 4 screws a bit tighter. Or you can remove the fan and cut out 4 little 2cm x 2cm cardboard pieces with holes in the middle and then secure the fan back on pressing the cardboard pieces in between the fan and then heatsink, this will make it act as some anti-dampening fixes and should reduce the rattling type buzzing noise down to appropriate levels. Good Luck.

well if u have a BIOS that can monitor the temps and increase fan speed when for example at 50C (which isnt bad at all really) it always does that on startup
