I have made some ramsinks for my videocard. I sprayed them blue. Does it matter that i painted them? Because of the heat?

don't paint the bottom of the ramsink where it connects to the chips...

The bottom is clear no paint on it. So no problem i think!:D

maybe use some TIM on it..just don't get any on the rest of the card/dimm ....you don't want it to short out.

SOrry to ask but what is tim?

Thermal Interface Material (i.e. Artic Silver). It Fills any microscopic voids between the sink and the chip; giving it a good heat transfer from the chip to the heatsink. Always apply a very thin amount and another thing make sure it stays on the chip since it really isn't an adhesive.

I know what artic silver is hehe. But i will put a thin layer between the sink and the chip, and put some superglue on the corners.

Well that what a "TIM" is. So whatever works...they do sell Thermal Epoxy..but i have heard that they are not the best when it comes down to heat transfer.

The paint is till drying hehe. I hope i have enough superglue. Thanks for your helps guys!

Be sure to keep us up to date on this, when you get the details worked out, a bit of a how-to would be nice as well.

I've got home made ram sinks on my Geforce2 pro right now....I used an old p70 heatsink and cut it into 8 blocks, each the exact size of one RAM module. I then Lapped the bottom starting with 320 grade sandpaper, then 600, then 1200 grit for the final lapping.

One other tip, a little bit of brasso works wonders if you want a mirror finish, just make sure your using wet/dry sandpaper.

The result: My card could now overclock from 400mhz (default) to 480mhz. Before the ram sinks, it could only reach 460mhz. Anyway, good luck with yours. : peace2:

Thanks they are dry now, i'm going to put them on right now. I will tell you all the results!

Wow they are amazing. Normally i was able to overclock my ram from 334 to 370. But now it is running at 400mhz! They even Look good!!!!

Well thats all that matters :D, just to add, spraypaint probably would affect heat transfer but to an extremely minimal effect, i think the volcano 7 is painted blue and its pretty decent

Actually the Volcano7, and others like it, are anodized frinishes and not the result of paint. But I would be interested to see what happens though with the paint. :?:

MMM i think i don't want to now what happens with the paint!!!
The ramsinks aren't hot to touch so i think the paint won't melt or anything. I hope!

Or hold heat in. :eek:

So you mean that the chips will heat more up?

If you were really good then you could electroplate the ramsinks, now that would be a good mod :D, and also you d have it finished properly like the volcano 7

They just maybe prevented from releasing the heat as fast as they could. ;)

Gold plating would be awesome.

where I work - I have to have parts anodized/plated all the time - for various reasons...although not gold plated

electroless Nickel plating looks beautiful - shiny & durable, around .0004" thick - chrome plating is much thicker & peels off more easily. Nickel is a little expensive though.

Anodizing is nice because you can get about any color you want red, green, blue, black - but it scratches off fairly easily. It's dirt cheap too - I get parts around the size of a CPU heat sink done for $2 - $4cdn depending on the quantities I get done.

Either on these would be preferable to spray paint I think - although the difference may not be enough to worry about

A nickel plating also stops copper 'sinks from corroding, aswell as looking pretty :D

Nickel is tough and corrodes very slowly - sounds like a great idea RDR!
