Yeah can just put some ram heat sinks on them. Thats what iv done but iv also got a fan blowing on them just to keep them a little more cooler.

I might do it. Its not the temps that bother me or noise. I want to overclock the **** out of it past 1ghz core.

Im just torn between getting another geforce 470 for sli and overclock the crap out of them to 900 core.

Or sell my single geforce and get radeon 6970 and hope i can overclock it past 1ghz and beyond and get a monster overclock.

The Mod can help maintain a decent oc but remember that your chips oc ability was set when it was pulled from the waffer and all the cooling in the world is not going to make it a better oc than what it was when you recived it. At some point regardless of core speed the chip is not going to give you postiive returns. My 560ti was able to hit 1275 core without driver crashes but my benchmark numbers were not off the charts because of the high oc, they were the same as 1000 core for the most part. The Mod is about silence first and cooling second. OCs are a bonus

Hi Guys, thought I'd just contribute to the cause of cooling down our GPUs.

 

Here are some pics trying to get a good fit on a fan blowing air directly onto the VRM+RAM.

 

If you have a reference 6950/6970 of the first batch with the 6950's able to unlock the shaders... a good 92mm fan will fit the 2 end holes of the PCB as shown in the pics. And from the spacing I am sure that the Khulers block will not come in contact with the fan.

 

If you're a little bit more creative, you might be able to secure the fan with 2 more spacers and zip-ties as only 2 screws can hold the fan. You might want to look for a longer and thinner set of screws and nuts as what I used here was a 6-32 and they barely fit the pcb holes.

If I'm not mistaken, isn't the fan mounted in the incorrect position?
The VRM/VRAMs (mosfets) are where the heatsinks are, and where you're more likely to worry about as opposed to whatever is on that end.

In addition, isn't that fan mounted... to blow air off the car and not on?

it's oriented correctly. the cooler would be in the way if it was moved over

I'd be curious to see of the difference in temperatures with the new fan in the way.

Just might have to do this with my old Rosewill fans...

What are the sinks you're using on the VRM/VRAMs?

For temps on the RAM and VRM I can't say because I haven't tested them out yet. I merely wanted to show everyone here that if they're concerned about cooling the VRMs and RAM it is possible to mount a fan on the PCB itself.


Right now they're on the heatsinks that came with my AXP-II which can be found here:

http://www.overclock.net/t/1068531/installing-axp-ii-on-an-pc-6950-2gb-56k-warning

 

I'm currently waiting on my universal GPU block and will swap them out for the copper heatsinks I purchased. Will create a build log once all the parts come in.

You know I will be honest, the more and more I read about having to worry about my VRM/VRAMs cooling, I feel like I should've just went with the AXP-II, or the Twin Turbo II just to be safe...

At this point, I've yet figure out how I am going to cool the VRM/VRAM, minus the passive cooling given by the heatsinks..
I really didn't want to have an extra fan blowing on those sinks, though.

EDIT:
And then a deal pops up in the classifieds for an Accelero Xtreme Plus 7970..
Looks like I'm not trying out the Kuhler after all.
If anybody is interested in grabbing mine off my hands, send me a PM!


BTW...if you're going to get the AXP-II make sure your case can fit it...but honestly...I don't see why you can't do the mod I did...if you already have the 620 just use it
