Ghetto northbridge cooler

post #1 of 3
Thread Starter 
So you have lapped your n'bridge and HS applied some AS5 and still not happy with the sys temps.
Why not try this VERY cheap, very easy, yet effective way of reducing them further.

Note that this was an idea i had heard coined on overclock.net although have yet to find a thread devoted to it. So this is my experience at making it and personal results. Also, this is based on you having an OK original n'bridge HS.

Required:-
1 x 62mm cpu fan
1 x sml tub of yoghurt (empty & cleaned)
some duct tape
1 x razor blade/sml knife
2 x sml nuts (10x5mm) & bolts, plus fibre washers
4 x sml screws with washers to suit gaps in HS
spray paint (optional)

You will need to remove the mobo for this mod.

1. After removing the mobo, you will need to replace those pissy plastic clips with spring tensioners that hold the n'bridge HS onto the mobo with some nuts and bolts. If unsure about clearance issues, put the nut through from underneath and secure. This will only need to be tightened about a half turn further than finger tight to obstain against damage.
2. Remove the std sml fan from n'bridge, do what you may with it but first use it as a template to mark on the bottom of the yoghurt tub the position of the screw holes. Make some tiny incissions for the screws to go into.
3. Using the duct tape, wrap the cylinder section of the yoghurt tub with it; this will provide it with some extra strength and insulation.
4. Take the cpu fan and position it on top of the tub. Use a screw to indent the tub where you need to make the necessary four holes. Use the razor blade point to twist into your indents; you only want to make the holes big enough for the screw to bite in, so when you just barely see the blade coming through on the other side that'll be enough.
5. Using the razor blade you will be cutting out most of the bottom of the container. Leave about a 5mm radius from the screw holes and around 2mm border from the edge.
6. You may choose to take this opportunity to dress it up with some spray paint now. Either way, onto assembly. Position the tub onto the n'bridge HS and screw that baby on.
7. When the tub is secured, you can then screw on the larger fan.
8. I plugged the fan onto the system fan pins of the mobo, but if you wanted to plug it back onto the n'bridge fan pins your gonna have to do some wiring mods that I ain't gonna describe here.

Conclusion, for less than AUD6.00 (though I had everything lying around spare so it was a big fat zero for me) this little baby (at ambient 25°C) reduced my system temps by 5°C's to 30°C and as a bonus the CPU temp also decreased by 2°C.
