I was expecting a E6400 in the mail on Monday and it may not arrive until Friday, Saturday, or even Monday.

I lapped my Tuniq Tower on Sunday expecting it to arrive then and since then the base of the heatsink has turned slightly brown with oxidation.

My question is would this matter? Should I lap it a few more times with 2000 and 2500 grits to get rid of the oxidation once the processor arrives? Or should I just clean it one final time with Alcohol and not worry about it?
 
No harm in lapping it again. :p

Try cleaning it with something slightly acidic.

Edit:- Like Vinegar :)

I have muriatic acid lying around as well but I wonder if that would actually cause pits in the heatsink since it's so strong.
 
Muriatic Acid is HCl. What the hell are you doing with that? Use vinegar.
 
used to clean masonry.

Exactly. It's quite a useful chemical so long as you have enough lime to counter the reaction.

Plus I do brass rotor cleaning on musical instruments and for some of the lime/scale you encounter it is the only way to clean them.

My take is that Vinegar is not that strong and a well diluted batch of Muriatic Acid (say 1 part to 50) ought to work well as long as I have a good neutralizer. Lime and Baking Soda are both great neutralizers although a Lime solution (lime and water) I find is the best.

I'm not saying I will use it but I've used HCl plenty of times in a diluted enough solution to wonder if that'd help.
 
do you know what molality the solution is?

I'm not sure. I got the bottle at Lowe's and it says 20 degrees Baum (33%).

It's pretty strong stuff though that's for sure. You really have to be careful around it because even the vapors can corrode. I found one warning on one website that it could erode your teeth as well but probably by then you wouldn't have a face left.
 
just touch it up with your finest paper and give it a alcohol wipe and dry just before installing.


thats pretty strong stuff and neutralizing it completely is more trouble than its worth IMO.

Fine.

It was more of a joke response than anything else :)
