Configuration: Unigine Heaven, 950 MHz @ 1275 mV, stock Antec TIM and fans
For those of you wondering if you can run 2 separate instances of the Antec Chill Control software with 2 Antec 920s in your system, here is the reply I received from Antec support.

Unfortunately you can only control one kuhler at a time. but if you got the 620, it has a built in sensor and both will adjust to your computers temperature.

Nice results there tomato16.

Can you post some pic goodness of your setup? Im always interested to see how people adapt their systems with this mod.

Here a update on my 670's I add some heat sink to them cooling on the 620's are amazing 30-40 degrees when im gaming which is sweet. The heat sinks were from Arctic cooling

450

700

Took out all the fan i had in it before, got a big 230mm fan on the side blowing in air so hope its enough to cool the vram on the cards with heat sinks

I LOVE the smal PCB on the 670!!!!!!! Awesome MOD! What's your temps!??!????? Did you lapp the 620? Lapp it dood!!!!
post #1704 of 8626
LAPP? sorry not sure what you mean but the temps idle are 20-22 and when I did a unhinged bench test max was 55 something like that on ultra settings it really cool doesn't heat up at all with them

The antec cooler is great. However, the bottom of the cooler isn't so great. It is a very concave surface. Meaning the center of the surface is higher than the rest of the area. With a heatsink, you want the entire surface to be completely flat. Take 400-600 grit sand paper and sand the surface back and forth on the glass surface. This will begin to remove the concave surface and make the cooler head flat. You can stop after you think your sanding all the surface of the copper head. Next take 1500-2500 grit sand paper and begin to sand the surface till it removes all the scratches in it and creates a mirror finish.

Just an update, I read from some of you experiencing stretching with your zip ties.
My kuhler 620 has been reseated once, a week after I first installed it.

After changing cases, fiddling with case setup, etc.... and 5(?) months of use I see no impact of wear.
Make sure when you line up the zip ties you have them fairly centered before tightening them down. I got the giant tube of zip ties from WalMart.

I also use ICDiamond 7 which is a thicker past than a lot of other TIMs so it may also provide a small bond between the GPU and 620 block helping it stay fixed in place.

I think temperatures have even come down. I ran the MSI Afterburner bench tool when playing with my OC yesterday and temperatures did not exceed 50'c.
It may be that the tool did not stress the GPU as much as maybe... OCCT.
I have NOT lapped this cooler either smile.gif

This mod just makes me giddy.
