Abit NF7-s chipset fan noise?

[sybrows]

Just built a system based around the NF7-s M-board, have noticed that when I boot up it makes a noise like there is something touching the fins of the fan on the MB, when I put my tower case on it's side it stops, if I leave it on it's side for a while, then put it back upright the noise has stopped. Otherwise the system is running fine temps are ok performance is wicked just this high pitched whining!!!
Any of you lot had this prob B4 ?

I have had this happen on my NF7-S motherboard too. The noise usually occurs when you first start the system up from cold, the sound goes away after about 30 secs or so.

I've also had this problem with my old Abit KT7 motherboard, it's the cheap fan thats used that causes the noise... doesnt really harm the system as far as I know.

If you're bothered by it you could always replace the northbridge fan with one of those Zalman passive heatsinks.

It's quite an annoying noise! I noticed that when I move the power lead for the fan it affects the noise, can it be remedied do you reckon, cos it seems like the lead inside the fan might be the thing interfereing with it. But is the reason it stops after a while because the metal casing expands with the heat... is it worth taking it off to have a butchers

Motion seconded; did that on an IC7-G recently where the fan developed the same buzzing noise. It's a known issue, and Abit will replace the fan if desired, but frankly, given the hassle in postage, delays etc. I'd take the Zalman option every time.

How much is the Zalman roughly and is it easy to fit?

i believe this is one of the cheapest places for it (if not the cheapest), free delivery :- http://www.thecoolingshop.com/produc...roducts_id/696

not installed one myself, but it looks as straightforward as you can get.

£13 for gold NB32J

£15 for blue NB47J

Both from Dabs. The NB47J comes with pushpin fittings and thermal grease only but is allegedly a slightly more effective cooler. The NB32J comes with pushpin fittings and thermal grease and thermal epoxy. Other than that, TBH, it's down to which colour you fancy...

The NB32J was very easy to fit, but if you use the epoxy you have to allow 20mins curing time after fitting. Also be advised you will not be able to remove the h/sink afterwards if you use epoxy. That said, your NF7-S should have the Northbridge fan fitted w/pushpins, so the issue shouldn't arise.

edit: Yup, fair dos Fondie, excellent price. The 47 should be the one to get.

As stated above, the NB47J can be had for £6.45 at The Cooling Shop. http://www.thecoolingshop.com/produ...products_id/696

If you take the top grille off the heatsink, it seems to solve the problem (atleast it did for me).
On mine, it looks like one of the fan blades was clipping on the cover. You will also get a bit better air flow by taking it off, and less of the "whoosh" noise due to this.

Cheers for the help guys think i'm gonna go for the Blue one, looks quite smooth. Thanks again for the advice

I had the same problem with the fan and then a few days later it died, I replaced it with the copper vantec iceburg chipset cooler.

Hi brought this one back to life as I just bought the Copper Vanteq copper cooler and am going to fit it tonight, but had a look and can't figure out how to get the old fan off the NB, do I have to go from the back of the motherboard? and do I just put a bit of Thermal paste between them or use one of the Pads supplied ?

You have to take the motherboard out of the case and use pliers to remove the clips on the other side, then clear the TIM already on the chipset and replace it with either the TIM which comes with it or Arctic Silver then put the cooler on, line the holes and push the pins though. hope this helps

Have I got to use a special solution for cleaning of the old paste mate ??

Well i just used a small bit of white spirt and a cloth, but i think isopropyl alcohol is better if you have some.
