Noisy PCH Fan

[Venoms]

My sabertooth x79 board has a PCH fan at the top left of the board, I have tried setting it to silent, turbo, and standard all of which still result in a loud annoying fan. I manually turned as low as I could in bios at 60% speed though its still the loudest thing in my case. My bios is full updated and I have no clue where to get ai suite if that would even help in this case. I think the fan just might be dying due to the age of it and the board. Is it possible to get a replacement fan for it?

might get away with removing it altogether and just attaching a really good passive heat sink on it.

 

looks like other x79 boards come with either active or passive cooling.

Is there like a replacement fan I could get since I don’t want to take apart the whole thing.

i'd give amazon or ebay a try?

I would start by removing the shroud and the fan, just because the fan may have a label on the other side with manufacturer, model number and potentially other things. You also need to know if it plugs into the motherboard with a 2 wire connector, a 3 wire (power + rpm sensor) or 4 wires (power, rpm sensor , pwm to adjust speed)

If there's a product number, you can try googling it (or parts of it) and hopefully you can find info like max rpm, air pressure, air flow, which is important because the replacement fan should have similar specifications... you don't want to replace with a fan that's not moving enough air to keep the chip cool.

 

Then you can look for replacement fans at distributors of electronic components or sites like alibaba, ebay etc

A starting point is this distributor of electronic components:

 

blower style fans : https://www.digikey.com/short/pmw3d8  (these are the ones that seem to blow air into a side and the blades are often different than regular case fans, not curved to push air down)

regular fans : https://www.digikey.com/short/pmw3w4

 

There's 875 blower fans and 14000 regular fans in the two links above. 

Use the filters to see only the ones around your fan's size then pick one with same voltage... then if you managed to determine some other specifications you can further filter using those.

 

Though this picture makes me think it's actually a fan commonly used on video cards of that time, where the fan has no frame and gets screwed into some holes in heatsink and pushes air through the fins of a heatsink :

 

 

So you may have better luck looking for video card fans .. example ancient radeon x1300 uses similar fans, or hd 3650:

I took a picture of the back of the fan

Can someone take a look at this fan https://www.ebay.com/itm/1-DELTA-AFB03512HA-12V-DC-0-14A-35-x-35-x-10MM-7K-RPM-SMALL-FAN-NEW-USA-SELLER/390321234118?hash=item5ae0f560c6:g:lvEAAOxy8F1RFhzL

 

I think its the right one, no?

 

EDIT: Realized it was the wrong one

[mariushm]

The eBay one is probably right. Though is it may be fake, or it may be recycled from some part, or new old stock, can't be sure it's genuine.

 

Oh cool, that's a Delta fan, and they make their datasheets available: https://www.delta-fan.com/Download/Spec/ASB03512HA-AF00.pdf

 

So it's a 35x35mm fan and 10mm height, with these specs:

 

 

Digikey has these in 35x35x10mm, there's 55 of them :

 

You could buy exactly the same fan :

2 wire version:  https://www.digikey.com/product-detail/en/delta-electronics/AFB03512HA-A/603-1128-ND/1619824

3 wire version:  https://www.digikey.com/product-detail/en/delta-electronics/AFB03512HA-AF00/603-1274-ND/2560398

 

You could get the more silent version, which spins at max 5800 rpm : https://www.digikey.com/product-detail/en/delta-electronics/AFB03512MA-A/603-1511-ND/2560635

 

These Sunon Maglev would also work great : https://www.digikey.com/product-detail/en/sunon-fans/MC35101V2-000U-A99/259-1562-ND/2757787

So does the 3 wire version come with the connector on it or do I have to manually attach that? (I have no experience soldering or putting the connectors on wires)

[mariushm]

They usually come without connectors, because the site above is distributor of electronic components, so companies may buy these to solder directly to boards, or use various connectors... it doesn't make sense to store same fan with 5 different connectors.

Yeah, you would have to splice the wires to your current connector and I can understand why you would be reluctant.

 

The eBay option may be better for you when you take this in consideration... also tough to argue with the price.

I ended up buying the eBay one, if it doesn't work oh well I'll look for another one to buy, thanks for all your help man.
