Yeah it has a lousy Vrm heatsink. Remember that the vrams are passively cooled. I'm running 1150/1500 at 1,2V. Max temps are 69C core and 78C VRM during BF3. Stock volts were 1,256V. Remember that these cards have a massive undervolting potential. I can run 925/1500 at 0,975V, while consuming <80w during BF3.

I'll probably add some copper ram sinks as well. I'll be shooting for 1300 core and 1600 mem. Try and get close to my 7870 hawk's numbers.

Good luck! I'm happy for my core temps, but vrm temps suck :L I think I could hit 1200+ core with 1,256v but Vrms wil be at 100C+

Cant speek for the power color but the only copper that fits on the sapphire is the tiny enzotech ones, MOS-C1. Though they didn't stick to the mosfet and just fell off.

The VRM reach 90-100C in Crysis 3, though I only have a side intake and bottom intake to cool the heatsink since it's red modded with a 620.

Adding Fujipoly thermal pad only netted a 3-4C improvement. I think the heatsink is just too small and gets completely saturated with heat. The thermal probe on the heatsink reaches ~90C when the VRM's are 90C+.

I'll have to see how the VRM's are arranged but i use these on my 760's

Hopefully they fit on the powercolor. Those wouldn't fit on the sapphire. I also have MOS-C10's which didn't fit, not because of the height but the length and width.

I have a pic I could edit in paint to show what I mean. The mosfets on the sapphire are VERY low profile, all the other chips around it are higher. Hopefully the powercolor is different.

I should check how low my temps would be at 925/1500 @ O,97V. When I get home, i'll test it out.

I hardly even had temps like that on stock cooling.

With the MK-26 it has stayed below 45 on stock and only went up to 46 when I did a quick 1125/1600 last night. Those temps are while running Heaven Benchmark on extreme preset. So far that is the only thing I have direct comparisons in.
