Hey,

I wanted to replace my northbridge heat sink cause it is getting hot, but to my surprise there is two chips under that sink ! The 2.0 something chip and the actual northbridge. Anyone knows if there is an actual aftermarket heatsink that could cover this 2 headed monster ? Can't find any....


Thanks, Really appreciated

I am about to order one of these. How hot is it getting?

yes that is correct

the 780i chipset is not pcei-e 2.0 - so how did they get it to 2.0? they added the extra chip.


the little chip to right is the pci-e 2.0 chip


yes - get a small heat sink and put it on it - you can get some from sidewinder have a few tiny and medium hs made for small parts around the cpu the mosfets and inductors

check the temp with your hand

if you have issues with stick, most have sticky pads, use artic thermal glue

Thank you, great answer,

Now, my only ''reliable'' way of saying it is hot is by touching it....

I cant seem to find an actual reading of the northbridge on speedfan. I mean, Speefan does find a lot of temperature sensor but how can I know wich one is the northbridge or southbridge. From what I understand there is no actual sensor embedded in the chip and the sensor is ''somewhere'' on the board.

Finally, I heard about putting some small heatsink on the mofsets, could it help if I want to push the voltage ?

I just ordered an Asus P5N-D 750i and an XFX 8800GT 512M.

your P5N-D is runnin hot? Did an optional NB fan come with the mobo? I have a spare NB fan that i can use, will that help? I also have a new Thermaltake Golden Orb and 2 nice new case fans i plan on runnin. Should i still need to worry about heat?

Are you losing performance due to the heat? like lower FPS in a game or something?
