Hello,

Can you guys show me some nice replacement for the stock p4p800se NB sink?
Stock is the black fin one with hook clips on little ringy. I've only found
the thermalright 1 copper piece version. Does any other fit? Preferrably
without adhesives.

TIA.

Looking at a picture of the motherboard in the P4P800SE user
manual, I can see you are going to have a problem. There aren't
the two holes on diagonal corners that exist on a lot of boards.
Instead, they have those crazy solder-posts and springs to hold
down the heatsink. Most after-market NB heatsinks have two "arms"
on them, that you adjust until they line up with the two holes
in the motherboard. I don't remember seeing any after market ones
compatible with the solder-post hold down scheme. And, I don't
recommend thermal epoxy, due to its permanence and warranty voiding
properties.

What is wrong with the one on the motherboard now ? If it isn't
making good contact, remove the springs, remove the heatsink,
and use some Arctic Silver on it. Once that is done, if the
heatsink gets too hot to touch for more than 2 seconds, buy a
40mm fan, and jam screws through the mounting holes in the fan
and between the last two fins on either end of the heatsink.
The fin spacing is generally perfect for the size of screw
normally used to hold a fan. It the heatsink is cool enough
that you can leave your hand on it, then it likely is getting
enough cooling and doesn't need any more assistance.

If the motherboard is malfunctioning, due to some kind of
problem with the Northbridge, then RMA the thing and get
one that works. That way, you won't risk the warranty by
damaging something while changing the heatsink.

HTH,
Paul

Thanks Paul. I don't really need to change it, and already got a 4cm 6k rpm
fan on it. The problem is actually the sink's fins are quite far apart.
What I did was plier the fins to make them narrower for the screws.
However, only 2 screws are bit in, the other 2 is just there held in place
but not really holding the fan tight.

It's not having vibrations though. And I think the NB as of now is doing
fine. I just don't like the fact that something's not 100% tight in the
box. And thought of changing the heatsink, those regular ones with comb
stick fins where it's easier to plier together for a tighter fit.
