I wanted to install a heatsink made for a northbridge on the southbridge of my p5n-e sli, but a capacitor is slightly in the way. Is is a problem if I bend it a bit, say 20 degrees? Will it give and not be damaged? I'l try to take pics and put them up.

Can you see the leads, or is it soldered tight to the board?  I would say it is tight, no way, maybe modify the heat sink a bit. Have a small grinding tool, or a small rat tail file would do the trick maybe.

I would say 20 degrees is a no. That would probably break something.

What kind of heatsink is it? you may be able to just cut the heatsink to fit, that would be the better way to go.

I like mudmanc4's idea of modifying the heatsink to fit the capacitor.
But if you are adept with soldering then if the capacitor on the board(southbridge) is tight  replace it with a new one of the same type.Most replacement capacitors have longer leads.Try a company called Newark.

That wouldn't be smart.

Cutting the heatsink is the way too go, and would be really easy. If the heatsink fins are in the way just get some tin snips and cut them off little by little.

Exactly, besides, the reason they stopped leaving any length of lead on the components id the high risk of a short. By shorting the two leads agist each other of a capacitor, you'll drain the charge, (remembering a capacitor will hold a charge even when not plugged in to a power source, thats what is for,simply put , it's a battery )  if you happen to make a circuit between the leads either on the neg or pos side, then you may just overload the opposing component, not good . Say bye bye to your mother board.

 Just modify the heat sink.

Like I said I'm also in favor of making the heat sink fit.
But if a person wanted to put a capacitor with just enough longer leads left to get 20 degrees without strain & making sure they weren't shorted to each other.Because if your not smart enough to do that you shouldn't be doing anything inside your PC anyway.The new capictor wouldn't have any charge yet.
btw I replaced 3 defective capicitors (swelling because of bad chemicals used by the manufacturer) on the MB of my old PC cured the problem & it has worked fine since.I didn't need to bend them so I didn't leave any extra lead but I'm sure I could have with no problems.

The northbridge is

I'l try bending it or filing it down. It isn't too far from fitting

Umm. How much cutting are you talking about? The fins are how the heat is removed from the component. Shorter fins = less efficient cooling.

I'm not talking about cutting the top off. I'm just talking about cutting the side down a little bit where the capacitor is. Only enough to make it fit. And since is the northbridge you could chop that thing up and wouldn't notice the difference because they don't get very hot.

Actually, I found a way to install the heatsink without bending or cutting anything off. The downside is that while my case was open, I thought that I would reseat my cpu hsf, ans I seemingly failed since my computer no longer posts, it just does the opening sound, the fans run for 2-3 seconds, and then restarts with the opening sound, as if I had pressed reset. Nothing ever appears on the screen. Does that mean my cpu is fried?

Its probably your motherboard if anything. I would start pulling off parts and see. could be ram if you left the ram in when you where doing that.
