A fellow miner had the same issue with his 5970s, I would look into replacing the thermal pads as they dry out over time.  That should drop your VRMs 20C I would think.  Reapply some thermal paste (Arctic MX-2 or 3 preferably), I did that on an old 5770 and it dropped GPU temp 5C which isn't much but for 24/7 mining every temp drop helps!

Could you elaborate on the thermal pads please? a link? a pic perhaps?
Thanks!

looking around for Accelero Xtreme 5970 but it seems to be unavailable.

are there other models that will work on a 5970.

Accelero has 3 different models (on newegg) but I can't see if they are compatible with 5970.  One of them mentions therm. pads and heatsinks for VRMs.  that sounds like something i might want to experiment with...

Anyone have any experience with Accelero or other aftermarket cooling?

Holy hell your cards are running hot! I pull 840Mhash/s on each of my 6990s keeping the temps below 80. Replace the thermal pads as someone else recommended, and turn up the fan!

The VRMs are running hot, I would expect them to be rated up to 125C and shutdown around 140C-150C (at least thats what the power parts I work on do.)

130C is probably okay, but I'd look into some of the other solutions that were already mentioned. Higher temperatures means lower efficiency. My 6970s vary 20W wall power between 7AM (coolest) and 7PM (hottest).
