Running Valley at 1250/1460 in X-Fire the 7870 hit 91C which is way hotter than the 270x around 70C max. I am going to replace the TIM and pads soon and had planned to do so. It's very good to see those temp drops.
You should at least be able to cool that core temperature down with some good thermal paste.
With your cards hanging upside down as opposed to mine standing vertically, you may need something with a little more adhesion than thermal pads . I am going to check the card after about a week to make sure the sinks are still making good contact with the pads.
I'm also contemplating sticking some thermal pads between the backplate and VRMs to assist in cooling even further. The 270X has some ventilation holes on the backplate for VRMs, but I don't have any way to get airflow over that spot on the card.

Do you have the ASUS 280X that is in your rig sig? If so, ASUS shouldn't void your warranty when you remove the factory heatsink. I had my 7870 DC2 under water, returned it to stock, sold it to a friend-of-a-friend who somehow managed to blow it up with 'a tiny overclock'
I was a nice guy and RMA'd the card for him, and had no issues whatsoever.
If you really want to be sure that your warranty will be intact after removing the HSF, either call or e-mail ASUS and ask them. I really don't think it will void your warranty when EK makes blocks specifically for the DC2 cards
I was looking on EK's CoolingConfigurator site and there are a few versions of the 280X DC2. Depending on which one you have, the card could have a fairly extravagant heatsink for practically the whole PCB, covering RAM and VRMs.
