I want to apply a few heatsinks to some of the RAM chips on my graphics card when I water cool it, and also to a couple spots on my motherboard...a couple quick questions...
1) I know if you "mix" AS epoxy w/ the regular AS 5, you can (hopefully) later remove the heat sinks if you ever need to RMA the product. Can someone give me some more specific information on doing this? Do you just mix 1/4 epoxy part A, 1/4 epoxy part B, and 1/2 AS5?...or do you mix the epoxy alone, then add the AS5?...or?...
2) After doing the above, just how feasible is it later that you will be able to remove the heatsinks later on? Or, on the other hand, will you have any problems with the heatsinks not being affixed firmly enough? (It all comes down the mixture?)
3) a) Is there any reason why applying a heatsink to a chip that is slightly bigger than the chip would be bad?...I can't think of any at all (and have even seen such stock solutions). 3) b) But more importantly, what about one large heat sink bridging 2 small chips (on the motherboard in this case)? Any real problems with that? (I guess you run the risk of heating up one chip unnecessarily if the other is substantially hotter, but is that a real issue?)
4) a) Since the AS is non conductive, but can cause some capacitance, the AS website says to line the chip leads with a "non-corrosive silicone". Can anyone recommend something in particular? I live right around the corner from an auto-parts shop...there's also a small mom&pop hardware store near by too...
4) b) Also, will applying such silicone invalidate my warranty, I assume?...I wouldn't imagine, also, that there is any way to really get it off later...?
Thanks!
