Title: GA 890fxa UD5 Northbridge fan???
Post by: CoolDude64 on October 19, 2010, 01:18:20 pm: Hi guys,
I have a GA 890fxa-UD5 motherboard. Before firing it up for the first time, I decided to read the manual again. It talks about fitting a NorthBridge fan. Previously I had ingored this as I thought that GigaByte used metal pipes to dissipate the heat from the NorthBridge and SouthBridge. The question is: do I have to fit a fan or fans on the NorthBridge chips?? I know the very early motherboards had a fitted fan on these but on later ones they used metal pipes to dissipate the heat. On this motherboard there are these pipes so do I need to also fit the fans as it looks like there is not much room to do this.
If I have to fit a fan where does one get them from and what is the size?
Regards,

David

Put another way - I don't have any heatpipes on my motherboard and it's doing fine. As a precaution I added a fan to the side panel that blows air on both NB and my GPU. Though it was mostly to improve the airflow down there rather than to cool the NB.

NB fans - that's really down to your imagination. You can fit it like I did or get some ~40mm fan that you then put on the NB or very close to it.

Worth mentioning is that with stock CPU coolers some of the air is directed towards the NB. Even if it's warmed up a bit it still helps move air around the NB.

Post by: CoolDude64 on October 19, 2010, 11:44:56 pm: Thanks guys, it seems that I am ok then. I have one fan at front blowing in; one at back sucking out; two on left side blowing in over cpu and graphics card; two on top sucking out and one on right side blowing in to back of processor on motherboard. I thought as the manual spoke of a NB fan I had to have one!! I have no intention of overclocking so I reckon my number of fans are enough.
Thanks once again guys.

I have 4 case fans and my rig's overclocked some :P.
