Minimum FPS almost tripled.

Fan maxed at 98% and temps maxed at 74C.
Interesting all I can find locally is ARCTIC SILVER Ceramique Premium High-Density Thermal, ARCTIC SILVER Arctic Silver 5 High Density Silver Thermal , ARCTIC SILVER Alumina Thermal Adhesive, Zalman Super Thermal Grease 2
& Zalman ZM-STG1 Super Thermal Grease. I actually replaced the TIM a coupelm days ago but I put genetic CPU thermal paste that I had there. It looked almost like the stuff I took out. I didn't really see a big temp drop. My memory overclock really gets my card hot still.

I don't know if any of the ones mentioned would be that efficient though to bother replacing it again.

Wow I might pick up some OCZ Freeze tonight from CompUSA. Contagion scared me with his screw thread, do you think I will strip out my screw holes also?

I just replace the stock TIM on my 480 with Shin Etsu x23. The goop they put on there was all the way in the end of the recessed heatpipes, which took me a good 30 minutes to fully clean with that arctic silver cleaning solution. I think there's still some left in there, but it's not touching the core so I don't think it'll affect temps.

I saw the EVGA thread where the guy spread his paste evenly across the die like people used to do, but I used an X pattern, based on this video:
YouTube- How Thermal Compound Spreads

The GPU die isn't much bigger than a CPU IHS, so I believe this will work just as well in the end.

Idle temps doesn't seem to have dropped much, but it could be because it's hotter today than yesterday, dunno. Load temps, though, have dropped around 5 degrees when playing Crysis so overall it was a worthwhile task to do.

i think you will be fine. the only four screws you need to remove are the spring-loaded ones and those should not have thread compound on them (mine didn't). one thing you can try to make things easier is run kombuster for a few mins before you attempt to remove any screws off your card. if anything is holding the threads, it won't after heating up.

Did you only add it to the core, and left the pads on the memory? also are you sure it's safe to use Shin Estu x23.. it's non conductive right? (i ask cuz i have the same stuff and wanna use it on my waterblock)

Sorry to double post, but this is different topic.

How is everyone doing so far overclocking there 480's.. I was wondering about a few settings I saw in MSI Afterburner, as well as Kombuster that i was going to see if anyone's messed with. In Afterburner there is a setting that says "Force Constant Voltage" and then there's a setting in Kombuster that says "Unlock Power Draw" I was wondering if anyone has tried either of these and if it has done anything different for them.

I just upgraded to MSI AB Beta 5 so voltage can go to 1.138 but I've yet to try it that high. I haven't went above 1.125v yet

Only on the core, yes. I didn't take off the metal block covering the VRMs and RAM. AFAIK, it's non conductive from what I've read. On the core, though, it doesn't matter as much since it won't touch the PCB, whereas if you were to put it on the vrms or ram, a small glob might seep onto the PCB.

Let us know when you go water, I'd like to see what kind of temps you get!

Any tips on OCing my 470? Im just running on the stock cooler until I can find a good after market air cooler.

I heard reducing the memory clock helps with temps alot?

Fan is at 70.

my 480 on water caps out at 850 core 1000 mem @ 1.075v. I try to push mem higher and it crashes beyone 1010, so 1000 is as high as I will push, and the core wont go any higher than 850, even if I push the voltage as high as possible. Idle 35C, gaming temps ~55C. Ambient 24C

My loop is the 480, OC i7 @4.2 (1.3625v). Rads are swiftech mcr220 and mcr120.

So... I now have my EVGA GTX480 SC in my pc and it is on water.

I have msi afterburner installed but I am unable to change the volt. How do I gain access to this control? (I have checked the boxes in the settings)

And also, my core, shader, and memory sliders are not anywhere close to what they should be.
core says 1900, shader says 809, and mem says 404.
