how to reduce the noise of my ATI 9800 pro videocard

firepol asked
Last Modified: 2013-11-10
I have an ATI Radeon 9800 pro (AGP) with 128 MB ram.

I bought a zalman cooler for my processor, but I figured out it's useless as the ATI videocard makes too noise.

Can you suggest me a way to keep my actual ati 9800 pro silent? Can I replace the actual fan with a silent one? What are the options?

I saw there are some kits such these ones ( http://www.arctic-cooling.com/vga1.php ) but i don't know if their purpose is to cool an overclocked card or to make is silent.

My goal is not to overclock my card, but to reduce the actual noise.

Thanks for letting me know.

Do you think I can "recycle" the zalman cooler if I buy it now for my ati 9800 pro and I put it on my next videocard? Maybe I'll buy another ATI, maybe a geforce 6800 GT...

My actual ATI 9800 pro has a "sealed" cooler. It doesn't look like I can remove it. should i remove it with force? In this case I guess I cannot put the original cooler back if I transfer the zalman kit on a newer card...

I have changed the coolers on several Radeons, so you should be able to do the same with the 9800 Pro.  There is either a set of screws or a plastic standoff that can be disengaged to free the cooler.  This cooler is reusable on other video cards.

thank you visual3dmaya... so it seems that the ati silencer is the best option if my goal is silence ;-)

i guess i'll buy something and then close this question when i'll see thew results...

thanks again guys
You have ATI Radeon 9800 pro, so it's needed the ZM-OP1 fan that in best case gives 20 db.
I like it is so big, i don like it is not made of Copper.
If ATI Silencer gives 15 db, i dono, from my point of view we need more help from experts on this subject.
I've got an idea:
you can replace, if it's room enough, with a bigger fan (power supply fan), which if it's supplied from 5v instead of 12v it  stays completly silent, i have 2 of them in my case and no noise. Being so big it may also have an important flow of air, it should be, must be at least ZM-OP1 generate.


Visual3DMaya: good idea to see what experts know about noise...

I don't understand your last idea to use a power supply fan (??). I mean, a tower can have only one power supply. You mean to add just another fan/cooler inside the tower and place it near my graphic card, and get rid of the graphic card cooler? Will this work?

I would say that the graphic card needs a cooler attached, "near" would not be enough... would it?
Yes, in case you use Zalman cooler, read on zalman page, it is there an .pdf document that says, for radeon 9800 you need also ZM-OP1 fan.
To reduce more of its noise, replace it with another fan, replace just the fun, look on zalman site its position visage the cooler. Power supply fans can be found at an IT shop or in a broken power unit if you have one. They are very silent when supplied at 5v, also (hope) much reliable in time and i think cheaper than ZM-OP1 fans.
I hope you manage to do the job. The red wire is 5v and yellow 12v. The fan needs only one of them+the black, red instead of yellow. If you wish you can buy an Y adaptor cable and modify one of its 4 pin connectors.

The Zalman ZM-OP1 fan comes with a variable speed controller, so you can make it as quiet as you like.  It's a very large fan which can move a lot of air even when spinning slowly.


The Zalman ZM-OP1 ( http://www.pc-cooling.ch/product_info.php?cPath=4_32_437&products_id=337 ) is even cheaper than the ATI silencer ( http://www.pc-cooling.ch/product_info.php?cPath=4_32_431&products_id=505 ) .

Callandor: I guess the principle is the following: when I don't play and use my PC for normal taska such browsing the web, writing etc. I can lower the fan speed and reduce the noise.

For watching a DVD or a DivX do I need more fan speed or is this comparable to "normal tasks"?

When I play, the vga chipset power is used, thus cooling is needed and I should improve the fan speed.

Am I correct with this assumption?
ZM-OP1 is only the fan with the speed controller. It would have  been nice a regulate one by temperature.


Visual3DMaya "ZM-OP1 is only the fan with the speed controller. It would have  been nice a regulate one by temperature.". Oh yes I didn't notice it, so i should buy also the missing parts in order tobe able to mount it on my ATI, right? What a noob i am ;)

So I see the the complete zalman kit ( http://www.pc-cooling.ch/product_info.php?cPath=4_32_437&products_id=2238 ) costs more than the double than the ATI silcner from Arctic ( http://www.pc-cooling.ch/product_info.php?cPath=4_32_431&products_id=505 ).

At this point I already know what I'll buy (I'm almost convinced) ;-)
You are right, as specifications say it might be silenter. (Arctic...)
But i think Zalman keeps it a little bit cooler.

I've used any slow, controllable fan available instead of the ZM-OP1.  The ZM-80C has such a huge surface area (it takes up two slots) that just blowing air over it improves the heat transfer.

This is another vga cooler I've used that was very good: http://www.newegg.com/Product/Product.asp?Item=N82E16835118117


Well, I've decided to wait for my new graphic card (I've ordered an ATI X800 XT). I'll see if it makes a huge noise like my ATI 9800 pro. If yes, I'll try some of the above cooling solutions you suggested me. Thanks again guys.


Thanks guys. At the end i bought an ATI X800 XT which makes a lot of noise like my old ATI 9800 pro. I didn't buy the zalman cooler but I guess it would have been a very good solution. i guess if it's more expensive it should have something more than the arctic one...

Anyway, I bought the ATI Silencer 5 ( http://www.arctic-cooling.com/vga2.php?idx=61 ). It reduced the noise really a lot. Now I can finally say that my PC is silent. Well, I still hear the noise of the hard drive, but I'm working on a solution for this.

Just a final note: I can hear some small noise of the silencer, but it's nothing compared to the previous noise.

So, thanks again for your help guys, I splitted the points accordingly, hope you'll help me again with other hardware problems ;-)
firepol, what hard disk (model) do you have?


I have a Western Digital 80 GB IDE, WD800JB, High End,ATA-100, 7200/ 8.9ms/ 8MB, here the specifications sheet from the site where I bought it: http://www.stegpc.com/details.asp?prodid=2159

Well, I've already bought a "kit" to reduce the noise ( http://www.pc-cooling.ch/product_info.php?cPath=5_198&products_id=2897 ), but I haven't yet tried it. A friend of mine told me that this particular kti is useless as the hard drive noise comes from the internal mechanics and not from the "vribrations".

I don't know if he is right or wrong: I'll try it and let you know.
As it writes here http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=248&p_created=1017429038&p_sid=qpX-xgbi&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9MiZwX3Byb2RzPTkxLDAmcF9jYXRzPTAmcF9wdj0xLjkxJnBfY3Y9JnBfc2VhcmNoX3R5cGU9YW5zd2Vycy5zZWFyY2hfZm5sJnBfcGFnZT0xJnBfc2VhcmNoX3RleHQ9YmVhcmluZw**&p_li=&p_topview=1 i dono and it seems that WD800JB don enjoy of a Fluid Dynamic Bearing Motor. If it is true, it don worth using it anymore in that silent system. Nowadays Fluid Dynamic Bearing is the standard.
It reduces both the noise and vibration of the platters, so rising the storage capacity. In this case you just change the hard disk. In my system a have 2 Maxtor and i don think i hear any noise from them. I cannot be sure because of the other fans.
That noise kit might be useful in case the hard disk resonates with the case, otherwise i don think, and usually don happen. Anyway, take care of cooling in the first place.
