I dont know if anyone else has noticed this but when i select reverse it seems as if an extra fan comes on, its very noticeable as a passenger !! Could anybody suggest why this is ?

Hey Guest👍👎 We're looking for reviews of your local CUPRA or SEAT Dealership - it's quick and easy to do: Leave a review now
It could be automatically putting the air con on recirculation so the fumes you 'reverse over' don't get sucked in.
My passat does it but its not something listed in the manual, it also does it when you use the windscreen washer squirty so you don't smell it. The fan sound changes and sound slightly louder.
Hope this helps...

Yep that is correct.
its very considerate of seat considering that i could smell the petrol whilst driving my Clio haha 
it doesn't do it with the windscreen washer though I use halfords scented stuff so i quite look forward to cleaning the windscreen. mmmmm apple
Tried the window washers on way back from work this morning and could smell the strong bitter smell of dealership windscreen fluid 
need to get some a that apple scented stuff

It also lowers the radio volume when reversing if you have rear parking sensors, such a clever car
The cabin fan, when the recirculating function is enabled, seems to be put under a heavier load, so maybe the bearing is a bit worn?
It should make the same noise if you select "recirculate" function.
One other thing, maybe scan the car and look at the recirc flap motor when selecting recirc as that motor might not be moving the flap(s) correctly and strangling the fans air flow? I think that the recirc flap motor moves two flaps and just the one as its description suggests.

Noise of the fan starts at 0:12.
The compressor noise is the one that appears just a little at 0:29
Anyone else experiencing this?

Edit: I won't fix this because it's not enough to spend money as the AC works OK, just wanted to know if it's normal

I did not hear anything nasty at all, not during the time the fan was speeding up/slowing down or the compressor noise after that - but that is not to say that you think it is okay. I'd guessing any reported Sanden compressors noises at engine idle and compressor not chilling the air will be a lot louder than that - maybe even "screeching" noises.
