WOOHOO!! Simply awesome! I did a different type of mod...since I realized you can use the stock mounting with only using 8 zip ties instead of 9...
Check it out!
Oh my gosh, it looks good when you first get it, but WOWWW is it concave. Took me 4 pieces of 600grit sand paper and then some 1500 grit, and still then I only got the area around the center where the die will be. I didn't care too much to continue lapping until the entire thing was done, I knew the die is like 1/2 the size of the heat spreader so I'd be ok with just the center lapped.
As you see I only needed the zip ties to tie down the mounting bracket to the card...
Freaking awesome! Room was SOOOOOOOOOO hot! Gosh! Talk about no airflow. But here's the result. Got upto 26C in the case. Usually is 22C or lower. So I expect at least 2C better when I benchmark again.
So legit. I was a bit worried that the paste got spread out too much since the cooler twisted around when I was trying to tighten up the zip ties..but seems to be fine. Right now idling at 23C when I've got a 22C case temp..lolz I'm happy with that.
VRM appear to be around 70C when checking PCB temp, surprisingly the heatsinks for the VRM's don't seem that warm....so I'm almost thinking the thermal pad is crap ASUS uses... VRAM is around 50C.
