My latest chipset fan from ASUS has now failed - lasted less time than original. Barely runs and only if I manually flip it to get it started. Varys speed radically from 500 rpm to 1800 rpm, and is prone to stop completely.
Other brand cooling fans have been tried by several users, and also some passive coolers. Keeping in mind I have four hard drives mounted, a long video card, and many cables in that area, I would like to try something other than another ASUS fan. Need to order something soon, as I cannot trust this computer to not fail if I leave the room for even a few minutes.
What long term sucess has been demonstrated with other options? I need reliability and faith to leave computer running almost 24/7.
Appreciate all comments from happy replacemnt users.

Kevin Estes offered this mod awhile ago:

Get this Pabst 40mm fan: http://www.endpcnoise.com/cgi-bin/e/40mmpapst.html remove the cover and the stock fan but not the heatsink. (It's easy) . Get yourself some #4 by 5/8 inch long screws ( 3/4 will work with 2 #4 washers stacked under them if you can't find 5/8 screws) and attach the fan to the existing heatsink. The holes line up perfectly. This fan is very quiet (19 Dba), moves alot of air, and keeps my chipset 10 degrees C cooler. My video card next to it is also cooler. The fan is low profile and fits just fine with my stock 6800gt's. I believe that it would also work with dual slot cooling with little or no modification. I've been running the fan for 3 weeks to test it before posting but for those of you who know Papst fans don't fail. The fan comes with a 4-pin molex so if you want to connect it to the motherboard you'll have to get a 3-pin converter. I just plugged it into the loop with all my case fans which are on a controller when I need to be really quiet. Hope this helps.

Also, I won a chipset fan in the Forum Wars and will be trying to mount that on my A8N SLI deluxe w/ 2x6800GT's carrying NV-5 coolers. I'll post my luck with that.

Happy??! Ecstatic better describes the replacement I made ( http://www.zalman.co.kr/eng/product/view.asp?idx=71&code=014 )
I was very sceptical about heatsinks for the Northbridge and properly cooling the nForce4 chip and reluctantly tried one of these (best investment Iíve made so far on my new PC (and Iíve spent alotttt)).
It is obviously SILENT and maintains lower (4-5 degrees (I have a 90mm fan blowing over it)) temperatures in idle and load.
The old rubbish, unreliable, whiney, loud, gay ASUS fan was literally kicked out of the bedroom window.

Thanks for the replies. Just a couple of mounting questions for Merc (or Kevin Estes) and TriGGa Death. I read thru the links provided and came up with these questions.

Per Pabst fan:
The mounting screws (#4x5/8"). What do they screw into? The motherboard holes now used by the pushpins? Other holes I cannot see until I lay the computer open? Do they need nuts on the other side of the motherboard to secure them? Or can fan be mounted without pulling the board (which I really hate to do again).

Per Zalman passive heatsink:
Do the mounting pushpins supplied with this heatsink work or must I try to salvage the pushpins now in use? To do so would likely require removing the motherboard, which I am reluctant to do now.
How warm(hot) does the heatsink get - I would guess that several of the cables may touch the tall heatsink unless I can figure a better way to run the cables. There are about 12 cables now passing thru that area, some having little play available.
-----------------------------------------------------------------------------------------------------

I was able to mount the replacement fans from ASUS without pulling the board by clipping the heads off the pushpins, then using the supplied new pushpins. The case has a fan mounted in side door panel that blows air inward towards the FX55 CPU (witha Zalman cooling fan). This fan adds a good supply of cooling air but does not directly hit the chipset area. Front fan blows back thru the harddrives towards the chipset area, but gets diffused by the drives.

Both suggested solutions are very interesting. Will place some order by Friday. Appreciate any additional comments on my new questions.

Hi David,

Sorry for the late reply to this post. I am having the exact same problem. I am trying to get a solution without having to remove the motherboard. Did you implement either of the suggestions here (Pabst or Zalman) and did that work out ok for you?

Many thanks,

/Brian

Brian,
I had thought this entire thread on the A8N-SLI was essentially dead - just browsing and looked again today and what do you know - I found this old Q&A alive!

To your question, I did indeed buy a Pabst fan back then but never installed it - still on shelf. I also have one new Asus replacement fan that they had sent on request that I never installed. If you are interested in either or both of these fans drop me an email. Where do you live? It is possible to cut top off the plastic pins and install fan without removing mobo if you have new pins available.

Do not remember exact sequence of events, but about the time the 3rd Asus fan died I also had my Crucial Ballistic memory sticks burn out again and the computer could not run for awhile. While it was down awaiting new memory (Corsair brand this time), I ordered one of the heat pipes used on the Premium model board and installed it, doing away with the chipset fan for good. I do not know of any source for the heat pipe at this time, but the Zalman passive heat sink may be a good substitute according to several threads buried in this volume. My heat pipe has proved reliable, but the board is now burning out the Corsair memory. I do not think the memory slots firmly grip the sticks and that this is causing the burnout, although the Corsair sticks have outlived two full replacements of the initial Crucial memory. I have to reseat the sticks about every two months or get gazillion BSODs.

The computer is still in active use but I never felt it stable enough long term to justify going SLI. Am currently building three new units based on Intel E8500 and E7300 to take load off the old Asus and hope it will last a few more years with lessor duty.

DFI board fans can fail too. A motherboard is more expensive than a fan, so buying a DFI is an unreasonable fix for this situation.

Hey dead? I've still got one on my main system!

The fans are on their way out though so I may need another one soon. :) Also I've upgraded it as far as it's going to go so time to bite the bullet and replace is fast approaching. I might have to let it fry though as the wife thinks of it as a "new" PC :( Even though it's mostly almost 3 years old I still haven't found a fps it won't play fairly well.

hi folks! just passing by...thought i'd add my own experience. bought an an8sli-deluxe with a dead chipset fan! as i am in UK, i was unable to replace the fan on asus Estore as they do not ship abroad. i bought the board to test the sli capabilities of 2x7800gt!
both are fitted with nv5's.
i bought 1x zalman zm-nb47j (as they have adjustable reach 2-pin sprung clips and because i saw an sli setup with one; can't recall the cards!)
and also 1x akasa AK-210 (stick-on style) and some akasa thermal adhesive tape.
didn't use the zalman 'cos the akasa was perfect and just avoided the fins on the nv5
the fan is a real whizzer, but can only be heard at bootup; just under 6000revs i think.
i used two layers of the tape to make up the depth of the chip which is very high; cut out to leave the chip in direct contact with the zalman's own thermal pad.
all is very cool!
very cheap too...buy a couple!

It is my opinion that the fanless MB designs are the best. Good heatpipes and radiators are better than an onboard high velocity fan; as long as you have good airflow through your system.
Intakes low front and exhaust high rear, in most cases.
You don't need to liquid cool your system to get very good OC from these types of systems.
You only need to have efficient airflow.
Proper airflow through the chassis is an absolute necessity for good cooling.
All the major MB manufacturers offer a fanless design.

I bought the zalman zm-nb47j after my original fan started creating some noise and not switching on sometimes.

My motherboard looked like a pain to remove and this is necessary so that one can squeeze the bottom of the plastic pushpins together to allow them to come back out through the little holes on the motherboard. I decided to try the alternative method and snip the existing pins that held the fan in place. When I was researching I had problems finding someone who had done just this so here goes with my experience!

It was more difficult to snip the pins than I thought it would be. First of all, my case restricted the amount of room I had to get my hands into a good position. The second problem was that the existing fan had a couple of plastic protectors that covered the pushpins. I used a pair of wirecutters (I think ;-) and I used then to first of all break the plastic protectors. These were quite easy to break although I had to be very careful of the little components sitting close to the pushpins cos one slip and you might damage one of these little fellas! Ok, now for the pushpins. These were very difficult to snip, they were thicker and more resilient than I thought they would be and I found myself twisting them back and forth a little to try and break them. Eventually they did break and I was able to push what was left of them back through the hole. After turning the case upside down the debris fell out and I hoped I hadn't damaged anything. Although the fan was taped down it practically fell off after all the abuse I had been giving its retaining screws.

I cleaned the existing thermal grease off using some white spirits and kitchen roll and hoped I wasn't damaging the little silver sticky up bits on the green board. Are they important? :/

Anyhow, at this point I decided to try the computer out and check if it was still working. It was hurrah!

The next part was the easy bit. Assemble the Zalman as per the instructions. Ensure the holes on the Zalman line up with the holes on the board. Then pop the new pushpins through the holes on the Zalman (while you have it in your hand). Then apply a little (!) thermal grease evenly to the chip. Finally set the Zalman on the chip and push the pushpins through the holes on the board.

Plug it in and voila!

My chip got to 38 degrees C in about 20 mins to half an hours heavy use (constantly opening and closing photos in photoshop). I will need to see how it performs in the next few days.

Regards,

/Brian
