Default Voltmodding a heatsinked 7600gt?

Well I'm running 2 7600gts in SLI right now and am thinking about voltmodding them. http://www.newegg.com/Product/Produc...82E16814125025

Anyone had any experience voltmodding these cards? What about this guide? http://www.vr-zone.com/?i=3330&s=1

Should I add heatsinks to any of the chips or capicitors? If so which ones? Should I see if I can remove the main heatsink and redo it with AC-5? Maybe add a fan in the side cover blowing air in onto the heatsinks?

Just for future referance, it's called AS5 (Arctic Silver - 5).

I would buy a Zalman VF700, or better yet a VF900 for both cards. It's a very good cooler and it comes with ram sinks. If you can't afford that, you can pick up some ram sinks for pretty cheap.

Apply a ram sink to every exposed memory chip with some Arctic Silver Adhesive (NOT AS5).

You're right, I don't know why I was thinking AC5.

Well I don't want to add fans if I can help it. I bought the heat pipe versions for a reason. If I have to add a fan I would like to keep it to one variable speed fan on the side blowing over the heat sinks. I'm trying to keep this as quiet a rig as possible while still overclocking a bit.

Arctic Silver Ceramique?

I've got a VF900 on my 7900 GT, voltmodded and overclocked.

I believe the VF700/VF900 is pretty quiet, though I don't own one - so maybe someone who does can comment.

My VF900 is pretty quite.

Keeps my volt modded 7900 GT very cool.

It's in the original post.

So I guess I'm still leaning toward voltmodding, redoing the heatsinks with AS5, heatsinking the memory chips with AS epoxy, and adding a variable speed fan on the side blowing over the heatsinks.


So which chips should I heatsink? Sorry Newegg I know I stole your picture.

hmm... that is a silet cooler, so is not going to be amazing unless you can get a good fan on the heatsink.

all the large chips are the memory chips, they should be sinked if you are overclocking the memory. i am not sure whether the ICs and stuff need sinking, they definatly do on the 7900s, but i am not sure on the 7600.

you could try searching the xtremesystems forums for 7600 voltmods, someone is bound to have done one there.

As I said, put a sink on all accessible memory chips. You should have some on the back, too.
