Cooling the North Bridge

post #1 of 13
Thread Starter 
I have an Asus X58 Sabertooth my i7 950 is running at 4116 and idle CPU temp is about 37° C so is the mobo...However the North Bridge temp is running at 61° C Idle and gets a bit warm during benching and gameplay, around 70°-72°. My question is because of the GTX 580's humongous size their is little hope of putting a NB H2o cooler on. Can I cool the NB from the opposite side of the case on the back side of the Mobo? Its an acrylic case so it wouldn't be that hard. Need some input...

You could put a little fan on the NB?

That is what I done. A tiny little fan, very tiny actually. Amazing difference, went from 70+ down to mid 50's while folding or gaming.

You couldn't cool it from the back of the case. Your best bet is to take off the chipset cooler and replace the thermal paste. From that alone you're going to see pretty substantial temp drops, and then if you would like to add additional cooling capabilities put a small fan like this on top.

Thanks Turrican9 I have a number of smaller NB fans I have collected over the years however I don't think I have enough room between the NB and the GTX 580

You just take one or two 40mm fans and put them on top of the NB heatsink

Shutting down now to do a little modification, thanks for the idea! Sometimes you need a prod...

Asus have been kind enough to have a M4 (?) threaded hole in the NB heatsink, just attach a fan there. I got my temps down to 45c from ~65c. =)

Thanks for all the input an so far so good...Fans and heat sinks do work, well...As you may or may not have been following I have been looking for a solution for the copious amounts of heat my northbridge has been putting off due to overclocking...It should be called overheating instead of overclocking...So I went to MicroCenter to pick up a small fan to blow on the ceramic coated pot metal they use to cover the NB...And well it didn't work very well. Maybe good for a degree or two and in some instances that is considerable but not when the Asus probe alarm kept going off in the middle of BF2 or Crysis. So I came up with a solution. Now I dont know how readily available these fans are but I had an old heat sink off of an old ATI vid card with an embedded fan. It was low profile and 12v. I started measuring. And low and behold after re-drilling the mounting holes and chopping the heat sink down the result is an Idle temp of around 57°c.


Stock Plegh!


And okay jb on the thermal paste, I like a more even coating over the entire chip


Always scrub your dirty chips


And wipe it good!


Low profile enough to clear the battleship of a video card the EVGA GTX580


Hmmmmm, should fit


A little trim is always good


Grind that dirty heat sink


Had to change and solder new connector to the fan so it could be powered by the motherboard


Check for mounting


Looks like a good fit


Plug her in


And what a nice fit she is

That is the Southbridge or ICH10R not the Northbridge (IOH).
