It's probably your fan resistor pack, A quick check says that on Volvo's the fan runs through the resistor pack on speeds 1,2 & 3 but on speed 4 the pack is bypassed because the fan is running at full speed.

I don't have a Volvo but I had the same problem on my car & I bought an uprated resistor pack (from flea bay) that has a ceramic coating on the coils & touch wood it's been fine since. :)

Loz is right, this is a common problem with the 850's. You need to buy a new or secondhand resistor pack which slots into the blower.
It should be relatively cheap an easy fix :)
