Hi,

I need to find a good way to cool the northbridge on my A7N8X.

Can anyone recommend anything or is this anygood

http://www.zalman.co.kr/english/product/NB32.htm

and how is this any different to the one that comes with the board?

This can be bought from overclocker.co.uk

just did mine today. little spring loaded clips hold the heat sink on. just squeezed the clips on the underside of the mobo and the heat sink popped right off. smother the bottom of the heat sink in thermal paste and stuck the heat sink back on again. seems to be doing its job quite nicely. thatks to Jye for the suggestion. now to overclock the fsb and the mulitplier. got her to 2.1 the other night before the ram let me down (reboot for no reason). temps now way down in my new case so i will attempt gain.

hope this helps

cheers

Hi sink,

thanks for the reply. TBH my case and MB temps are pretty low anyway (thanks to a half decent case, fans, heatsinks etc etc) but I wanted to get my temps as looooooow as possible before I start ocing.

didn't know it was held on by a clip on the underside of the MB. THat means I'm gonna have to take it all out again

I just got a 4cm fan + heat sink and modded it to fit on

I just had a thought.....apart from space what would stop you using say an SLK heatsink and fan normally used on a CPU? Surely it's the same principle......HS contacts with the die on the Northbridge.....just a thought

suppose you could but you would have to be certain that thermal glue was up to the job. 300 hrs to cure in some instances.

marxsmann, you might need to heat the NB heat sink with a hairdryer to soften the glue like thermal compound thats used as standard. Mine took a fair bit of heat and gentle twisting. It just depents some fall off

I cleaned up the HS and then lapped it as its quite rough. If working correctly the HS should become warm to the touch, i.e doing its job and talking off heat from the NB. The SLK heatsinks are huge, far to heavy and tbo would be overkill for the NB. I have a Zalman fan bracket with an 80 blowing onto a Z80 heatsink for my 9700 Pro, this fan also hits the NB so I get pretty decent overclocks. A small 486 fan or something would probably sit on the northbridge heatsink with a bit of fidliing.

GL.
