I have a Gigabyte GA7VAXP motherboard and all of a sudden the Northbridge fan has become very noisy. Would it be OK to remove this, it is mounted on a heatsink, or do I just put cotton wool in my ears?
Yes ! just put cotton wool in your ears and look on as your pride and joy overheats. I do not know if your fan has ball bearings but if so you could try applying, when the PC is switched off and cool, a very small drop of light oil (watchmakers use it) with a pin. If that does not work get yourself a new fan e.g. computer fair and refit it to the heat sink with the special paste provided, it's designed to help heat transfer
I have the same board - and my fan went noisy as well.
I went to the shop where I bought my pc (specially made) to discuss the matter.
It is interesting that later versions of the motherboard don't have a north bridge fan! So we took mine out and tested the machine. Even with fairly high-intensive graphics programs running, the chip did not overheat.
So, based on the lack of fan on newer boards and that trial, I had my fan removed. The pc is a darned sight quieter and has given me (and I emphasise the 'me' bit) absolutely no problems.
i may be very wrong here but the northbridge on most mobos do not get very hot if you have adaquate case cooling unless you are into overclocking.saying that you can always buy a replacement fan or go for a silent solution like click here
