Both are of the non-reference HIS design, with a large heatsink over the core and no memory cooling as such.
Removed the coolers and replaced the thermal gunk with Arctic Cooling MX-4 resulting in much lower idle temps and load temps.

I redid my paste on reference sapphire cards and I noticed an immediate improvement. I used some cooler master cheap stuff too. I cap out at 74 overclocked to 900 after an hour of bf3
