Swiftech Heatsink vram question, thermal pad or TIM?

post #1 of 7
Thread Starter 
I am putting my Swiftech heatsink back on my gtx470 shortly, not sure whether to use thermal pads, or TIM on vram's.

When I first installed it following the Swiftech directions, they had me use the AS Ceramique included in the kit I bought on the vrams. That was fine, I think I did an OK job applying it.

I was modding the heatsink to fit my old h50, and got a bunch of metal shavings in the thermal pad that went over the memory chips. I ordered some replacement EK Thermal pads the other day, and should be arriving in the mail shortly. I think I will have enough left over that I could use thermal pads on the vrams, should I just do it?

IIRC the reference cooler had little square thermal pads cut out for each vram to begin with, so I assume it would be fine. If I did use thermal pads should I cut out individual pads for each vram, or 2 square for the 2 sets of 6 vrams, and one rectangle for the 3 vrams below in the pic.

Also worth noting, I have since used the rest of the Ceramique on different projects/tests, so I'd have to run up to radioshack to get more.

it may be best to just use the pads, as the tolerance on the block may not provide contact if the AS is used.

Ok, sounds good, I was leaning in that direction, just wanted to check.

You can't really tell in that pic, but where the TIM is spread there are little squares that rise up from the rest of the heatsink to help make contact.

Will do, do you think I should cut out little individual squares? Or would 2 larger squares be OK?

Its kind of hard for me to see, but big squares should be fine, as long as they are all the components it's being applied to are at the same height. Its not an exact science, there's some wiggle room.

Either or is fine. Although they need some type of cooling its not as serious as a CPU or GPU. Thermal pads, or thermal paste either or would work.
