Anyone have a Gigabyte gtx 670 windforce 3x in SLI?

Now that this card is around £60 cheaper I'm thinking it would be a good time to upgrade to an sli configuration. Do any of you guys have this card in SLI? My main concern is temperature. I've heard this card gets really hot in SLI. Any other insight into this setup is appreciated.
