Modded the fan profile in the bios to 5% initial speed, and this got rid of it - must just be an odd thing that only happens at certain rpm.

jb_fxtRoyal - those temps are fine. Personally, I wouldn't want any GPU temps above 90C and yours are well below that. VRM temps are very low - possible that the stock fan position is better at cooling them than the fan on the PCS.
I don't know much about WOV, is that an old game? best to test for temps on the most demanding software you'll be using - for instance on 3D Mark 06 for me, the VRMs never get above 90, and the GPU only touches max 55 at current fan settings, compared to VRM ~ 115 and GPU ~ 65 on crysis.
Modding the bios -
First use GPU-Z to save a copy of the original bios, using the icon to the right of bios version.
Download Radeon Bios Editor 1.13 - http://www.techpowerup.com/downloads/1148/TechPowerUp_Radeon_Bios_Editor_v1.13.html
This allows you to change all the bios settings - note: from what I've read, modding the voltage in the bios will not do anything on 4800 series cards, a physical voltmod is needed.
Original Powercolor bios seems to use a step fan setting starting the fan at 60C at 2% moving straight to 38% at 70C. If the only thing annoying you is the grinding, you can just alter the 2% values to 5%.
Due to worrying about the temps, I've gone for the transfer function option, with min% at 5%, then sloping starting at 50C going to 100% at 80C.
Save the bios under a new name, then flash using Winflash - http://www.techpowerup.com/downloads/1122/Winflash_2.0.1.2.html
Best to close down any other programs before doing this, and be aware flashing any bios always carries a risk.
Note - seems Cat 8.8 drivers don't like being installed if you have a bios with modded clocks.
Hope that Rivatuner works with these soon, it is a lot easier than mucking about with the bios.

jb_fxtThat looks like a pretty good game royal, will definitely recommend that to one of my mates who's really into flying and flight sims.
The VRM temps are the bottom 3/4 in the pic below - they're called VDDC Slave temps.
