No, it isn't the left little heatsink in the corner. On my stock heatsink, my vrm stay in the high 40s low 50s while my actual gpu gets to 70-75C. If there was a sensor on that little chip, it would get much higher than 50 because the airflow will hit that chip after going over the gpu.

Your temps look good. 80C on vrm with 75C on gpu is good. The vrm on aftermarket cooler is getting cooled with warm air that has already cooled the gpu. On the stock sink, the vrm is cooled first and then the gpu gets cooled with warm air that already cooled the vrm.

This. I'm surprised this comes as a surprise to people, all aftermarket heatsinks with the tiny VRM sinks suck for VRM cooling. This has long been a problem with HD 5xxx and it still is with HD 6xxx. Even giant coolers like the MK-13 or Accelero Xtreme Plus suck for VRM cooling. It's why Thermalright makes these VRM heatsinks: http://thermalright.com/products/ind...t_id=29&id=104 (note, that is not compatible with OP's card).

I believe Zalman makes a stand alone vrm cooler like the one that came with my VF3000A.
Here are my VF3000A results.

Are these temps with your cooler running full speed?
How hot is your room?
Even your stock cooler temps seem awful high stock voltage.

has anyone gotten this yet?

http://www.gelidsolutions.com/produc...1&cid=13&id=62

I'm thinking this might be a good solution.

I'd try it, but I have no idea where to get it. nothing came up on google.

My VRMs top out at 55 with the new cooler I through on. Previously they were hitting 70 or so and it's just 2 of those dinky sinks that they through in.

That's exactly what we need. Looks like an oem part which is wierd. And the one in the picture looks to be wrong because it would hit the capacitor on the card.
