Ram Heat spreader

[Pob255]

I've just got myself 2 sticks of 1gb ddr2 memory from scan
http://www.scan.co.uk/Products/Produ...oductID=527001

I will be underclocking it, as my ASRock motherboard only goes up to 667mhz on the memory.

Now I was wondering about makeing a heat spreader for it.
It's probably not going to require a heat spreader and they are dirt cheap to buy, but I was thinking of makeing one because that's more fun.

Any tips or advice on makeing a heat spreader?

I was thinking of getting some copper sheet and ether cutting two rectangels or one larger one and folding it over.
While I can use thermal paste for connectivity, what would be the best methord of holding them on to the memory?

Problem number two is that they've got stickers over the chips on one side which both say amongst other things "Warranty Void If Removed"
So would it be fairly pointless putting a heat spreader over the stickers?
or
Would it be best to carefully peel them off and stick them back on if I need to RMA it in the future?

Think you'd be better off using thermal pads between the chips & heatsink, that's what the memory manufacturers use underneath the heatsinks.
stuff like Shinetsu 25x25mm Thermal Pad for example akasa do some as well.
