a8n-sli chipset heatsink fan

[PerPixel]

Any idea about that setup?
www.mooglemolestors.com/albums/SLI/DSCN2174.jpg

The noise is driving me insane so my choices are Danger Den A8N chipset block + Zalman reserator 1 (300$) water cooling or get a small enough and silent fan. The heat inside the case is not too bad with all case fan running:

CPU:37
NF4:42
GPU1:63
GPU2:61

I was checking the swiftech fan but im afraid it will touch the top 6800GT heatsink and with the heat generated by the GTs the zalman heatsink cant do it. Any idea or did someone with a setup like this could change the fan?

@transman: excellent information - thx a lot!!!... im sure many people will go for that solution, including myself ...

@cdcushman: sure, pl let us know, how the things turned out with your system.. as soon i will get the papst, i post it too... unfortunately over here (switzerland) the shipping is rather expensive so i need to find a shop tomorrow which will order it for me...

stay tuned...

Been sick Going to install soon, when my nose wont drip on the mobo. :frown:

Its LOUD, especially when I have SilenX fans everywhere else.

There is "just" enough room to fit an NV 5 Silencer over the heatsink/fan that comes with the mobo. The plastic is about 1mm away from the top of it!

So you only have 2 options: mod the NV 5 like I did and replace with a larger heatsink or fan no more than 32mm high - or replace it with a quieter heatsink/fan that is no higher than the original (1cm).

... or use a different VGA cooler!

Jimbob,
Thanks for the input. I going to try the mod you described. I like the silencer 5 and really want to quiet down my system. If the Silencer can perform two jobs, vid card and chipset cooling, I'm game. One fan will replace 2 noisy ones. Besides for me, passive cooling in not possible as I plan to overclock.

If you replace it with Zalman ZM-NB47J heat sink, but temperatures of the chipset (I mean temperatures measured on the part of the heatsink, which is in contact with the chip are arround 49 C. Though it does not influence much the performance in usual case, it is not the normal operating environment.

Therefore additional cooling is necessary. It is always better to have a larger fan with less RPM. I have used a comercial airpipe from "GEMBIRD DC FAN SB-A" for arround 2,5 EURO. It is originally a 12V fan, which I have connected to 5V (this way it is no sound whatsoever). With such setup temperature of the chip (measured again directly) gets t0 29 C. It is 20 degrees decrease which ensures normal operating regime for a chip. If a small dB tradeoff is no problem and you can connect a fan to 12V then you shall get temperature of the chip close to the temperature of the case)

Here are some picturesshowroom

glassy: just checked your link... Whered your vid cards go!!!!! ANyway, it seems like a novel solution. However, IN my case I could not fit that blower becaus ethe 6800GT's extend way over the heatsink.
I just recently installed the Zalman myself along with two vf700-cu's (it was a mild pain b/c you have to clip off a few fins of the ZM-NB47J)

I tried the Zalman passive heatsink and found it too hot for my liking. After a little searching I came upon this Titan VGA heatsink It has an optional plastic fan guard when left off makes the heatsink only about 7mm or 8mm tall. It fits perfectly below any video cards. It also has a pair of blue leds in the fan and it is quiet (< 22 dBA). I had to do a couple of small modifications to get it to work. First, the holes had to be slotted slightly as the VGA mounting holes are 1mm to 2mm longer than the northbridge holes. No problem with a dremel motor tool. Also, to keep the springs from slipping into the slots, I added a couple small washers. This was probably not necessary but just a precautionary step. Last I put a plastic sleeve around the RF choke that comes in close proximity to the new heatsink as can be seen in the pictures. I actually used a section of plastic from a bike chain lock picked up at a local hardware store for about $2.50 Heat shrink tubing would probably work as well. Again this was done as a precaution. The heatsink kit also comes with a nice tube of silver compound. My pics: Heatsink Pic 1 Heatsink Pic 2

rgrimm, what are your temps with that setup? That would look sweet with my rig and the dual VF-700's I'm getting!

 

[Sakaali]

You guys got me convinced of the Papst 412FM so I ordered it today. Hope it works! I have one question on the screws: can someone tell me the exact dimensions in millimetres (length and width)? I guess I'll need to go to the nearest ironmonger's...

With the original fans on the chipset and graphics card I would have become deaf soon. Hopefully Papst and the Zalman VF700-AlCU will help me.

 

[Kanchi]

Im going crazy here too, it was fine for some weeks but now its making more noise than a lawnmower. My question is: will the papst fan fit with a silencer 5?

Also hasn't asus given an official response yet? Cause this is insane.

 

[alkemyst]

I had the NB47 on my A8N-SLI....my new K8N Neo4/Platinum has a 5.5K fan that is much quieter. I think the extra 3k the ASUS spins at is too much.

 

[imported_CW]

I also ordered a Papst, but the 412/2 version, which has a 3pin molex, so I could plug it into the motherboard and monitor the RPM.

I'll tell you my experience next week, when the fan arrives (I hope).

 

[killa62]

Somoeone is selling the papst fans on ebay.
@ 18.75 for two, that's pretty cheep
Link here
99.7 rating is good too with 5538 score...
so go and score some fans ...

 

[imported_slippy]

I removed the top metal plate and the fan today since it was starting to wheeze and whine like crazy last night.

I was absolutely shocked by how stupid the whole design was. At 8000 rpm this fan had to be generating more heat than it could possibly alieve from the heatsink!!! The fan rests directly on the heatsink!!! Converting its heat directly to that heatsink!!! I can tell you right now that this fan is cooling nothing.

And they have that metal protector over it, in case the fan flies off I suppose? REgardless, that cover is only hurting the airflow as well.

The heat sink itself is actually very good. I see no reason to buy any other because it is of quality material.

Since I have a xaser case which came with 5 fans, I have 2 standing up near that side of the motherboard aimed directly at the heatsink.

Now my temperature is roughly 2C cooler than it was. It is running at 27C stable rather than 29C, and is 25C at start-up. Also, I'm not having any more noise issues.


So, my advice for cheap people like myself (I slept on this one to try and figure out how to make this work without buying a ridiculous $40 fan, or a $20 dollar papst-after shipping).

First, take off that cover and put it in the box the asus came in, that cover is a piece of crap.

Second, take the 3 screws behind the fan blade out, and for the love of humanity, throw that thing in the box too, or bury it... whatever you deem appropriate. That thing is a piece of crap, even with a fan controller since that thing heats more than it ever could possibly cool.

Third, buy a cheap fan or use an extra one if you have it handy. Try to make some room where you can get a fan on that side of the case. Get some rubber like material, that is electrical safe and use that as a base on the bottom of your case (the floor of the case). You can tape it there... then take the fan and tape it to that (this is to keep your case from vibrating too much because of the fan).

One of my fans in that area has a fan controller, so I've been able to test how it effects the temperature readings by turning it up and down... you might consider the same but it isn't necessary.

Yes, it is a bit of a jimmy rig, but you can take that idea and modify it more professionally with fan grills and the like... but since I'm not inside my computer everyday since I'm more of a user than an enthusiast, it works just fine with me.

Keep in mind that I'm not a professional, and that you use this advice at your own risk. If you're not completely stupid, you might be able to pull off a variation of it that will work best for you.

Those 120mm quality sleeve fans, (can't remember the name right now) which sell for $5 online might be a cheap solution for people without an extra fan.


Since this was my first build I'm a bit embarassed to show any pictures sice my wiring is a bit of a rats nest. Though if enough people want to see it, I might.

On my system, the spacing between the bottom of the heatsink (top of the chip) and the bottom on the NV Silencer 5 fan shroud is approx 17mm. Whatever combo of heatsink/fan you use needs to be less than this or you will need to perform some mods.

 

[Kanchi]

So how much higher will it be with the papst fan? (using standard hs)
Also how hard is it to replace? can you do it without having to remove the board from the case? ( just about 0 xp here)

alkemyst,

You have two mainboards ASUS A8N-SLI and MSI K8N Neo4 Platinum (MS-7125)?

I'm considering between those two boards, wich one you would recommend?

What is your processor, is it Winchester?
Do you have that max. HTT/FSB 219MHz bug with MSI?

 

[JJK80]

I think that all ASUS A8N-SLI mobo owners should e-mail to ASUS and
complain about the fan, otherwise thay ignore it.

Guess ill get the swiftech http://www.swiftnets.com/products/mcx159.asp

Voodoo use it on the Omen without the fan

Wha? Does the Swiftech really cool the NV4 chip enough passively, or at least better than the Zalman? And clear a non-watercooled solution?

 

[geogecko]

That thing is probably at least twice the weight of the Zalman. That copper base helps also. That is what I'll be using...

 

[Kanchi]

I guess Asus customer service isn't much help either:

Dear Friend :
Thank you for contacting ASUS Customer Service.
My name is ***** and I would be assisting you today

Sir, Becuase , You know , the chipset itself has great quantity of heat . So it will run at the high speed to driver the heat . maybe it will send some sound , but if it is big, you could contact your dealer for advanced test or even replace /repaired .

Best regards!

Also I just looked at the papst site and I noticed there are different types of 412F fans, the 412FM which was mentioned here is the slowest with 4300 rpm and the 412FH is the fastest with 6000 rpm.
Wouldn't it make more sense to go with the 6000 rpm as that comes closest to the original fan performance wise? (also, it's the only one I found in shops so far)

I forgot about the copper base; that'd definitely work better than aluminum. I'll have to take some measurements first (I'm running dual 6600GT cards with Zalman coolers). If it'll fit, I'll go with that over the Zalman NB cooler.

 

[geogecko]

It would be interesting to know if it works for you. I'm not sure of the diminsions, but I'm sure it's on Swiftech's web site. I bet if the Zalman barely fits, then this thing probably won't. It looks to be a little bigger than the Zalman.

 

[linus1891]

I have the Swiftech MCX159-R on my ASUS A8N Sli deluxe. Works great ! I have Leadtek 6600gt.

HHHHHEEEEEELLLLLPPPPP!!!!!!!

1st board - Ran for awhile with chipset fan, everything fine, but loud. Replaced with Zalman NBJ47. Quiet, but my secondary IDE never worked again. RMA'd for new board.

2nd board - Installed NBJ47 before installing the board. Was even more careful about removing the pins and used Arctic Ceramique. Took about an hour to get back into Windows on this board, memory issues. Strange considering I had the same bios settings as previous board. Finally into Windows on one stick. NVMonitor shows System temp steady around 54 celcius. Higher than I have ever seen. Had 4 or 5 programs open when the computer shut down. Turned back on. During boot, when the little blue thing is scrolling, it locked and showed some purple squares randomly over the windows boot screen. Next time and every other time I tried to boot, fans would go, but nothing more. Asus tech support says temps should not have been a problem. He suggested I focus on the power supply as possible source but agreed to RMA this one.

Now using 1st board and sent 2nd board back. First board runs f*&%ing awesome (except no sec. IDE). Can game for hours, and run a project in Nuendo that maxes the CPU, no issues (my main program for this computer). Haven't done any benchmarking as I'm on my 5th windows install in less than 3 months and I'm sick of installing software and running benchmarks so unsure about full stability yet.

Is this really that dangerous of a mod? Could my power supply be the problem, even though it works fine on board #1?

I need to get this nailed before board #3 arrives!

I am audio engineer and I use this pc for working on sound (to be brief) so I really want to avoid using a different fan. Trying to go as silent as possible.
