R9800pro mod.

[lhgpoobaa]

Indeed a cheap and effective mod for slightly higher overclocks or summer proofing.

i would do the fan thing but i dont have any bracket for it or anything.

It's both cheap and keeps your video card warranty intact.

My mod is embarassing.

It's just an 80 mm fan taped to the long edge of an old video cassette. This has the just the correct width to position the fan to blow both above and below my video card in my mid-ATX case. If I don't want/need the extra overclocking I just take the cassette out of my case.

Someday I'll get around to picking up one of those <A HREF="http://www.zalman.co.kr/usa/product/fb123.htm" target="_new">Zalman fan/brackets</A>.

I tried to post this yesterday, but THGC came to a craw:
I can help but get a little laugh out of that. I sure like to see how you got the fan in position with some black tape. You got to do what you got to do and you proof there are no rules to go by. I bought a fan thingy for my video card. It’s two 80mm fans that hook up to the PCI bracket, but can be a problem if any of the PCI cards stick out, if they do then you have to move the cards down, say a sound card. I don’t use it much now because of that, plus when ever I had it in it seemed I was always having to do something that I had to take it off and back on and it became a pain, not only that, but it only either blows or sucks the bottom of the card. Like you said it’s best to hit both side. I tend to agree the HS will help be stable and the fans would help more for OC, since it will move the air out quicker.

That’s a good point I think I’ll move the air direction of my two turbo fans, because the air coming from the back to the front gets the top of the card, but not the bottom. The reason I went that direction is because where the fan is in the front of the case my HDD is right in back of it, in the middle of the fan. But being it’s a turbo fan I’m sure now on second thought that it won’t have any problem getting air pass the top and bottom of my HDD. And since my video card is lined up with the HDD the top and bottom of the video card will benefit from the air flow.

I’m thinking your black tape and video cassette might be more affective then the Zalman.
It doesn’t look like it does all that well to me, assuming it doesn’t interfere with the GPU or any PCI cards. That’s what a fan bracket does that I had mentioned and only does one side. The Zalman does both, but still think a fan blowing right up against the GPU would be better.

Actually, the video cassette mount was a compromise. With my old GF1 I found two fans mounted diagonally, meaning on a 45 degree angle to the back and sides of the case, worked best. Seems a 90 degree angle causes back pressure, dead air, or standing waves (not sure which) and hampers cooling. The 45 degree angle was worth about 1 or 2 mhz of improved memory overclocking.

The problem was I couldn't find a convenient way to mount them. I was using the video card and one PCI card has shelves (which you can do in a tower case). One fan stood on top of the video card and one on the PCI card beneath the video card. (Did you ever tape fans to your adapter cards? LOL!)

I did this until the day I was lazy. After working on my PC I didn't bother taping the top fan. I just stood it up on top of the video card and forgot about it. That was until I accidentally bumped the case. The fan fell over. It hit one of the RAMsinks (I presume, very ugly sound) then the fan proceeded to fly out of my case (which was always left open during the GF1 days).

Fortunately nothing was damaged (not even the fan) but I decided that the fans were mounted a bit to precariously. (just a bit!). That's when I started using the video cassette. I know it doesn't sound great but at least it can't fall over. It's sort wedged between the PCI cards and the case side panel.

I looked at the Zalman pictures. Did you notice that one of the FB123 bracket pics shows the it holding two 92mm fans, one over the CPU and one over the video card? The FB123 model allows the fans to pivot which would help in fan positioning.

Now I'm really considering one of these. I wonder if the Zalman bracket can support TWO 120mm fans.

Interference is not a problem for me. I never move/change my PCI cards. Once everything is tuned, tweaked and positioned I won't have to move anything.

Yeah I notice the fan positions and the tilt. I think it would be better in the fans where able to tilt downward towards the fan, not just tilt left/right. That way there would be a more direct hit of air on the card.

mmm now you have got me thinking about 1 120mm lowspeed panaflow fan cooling the front of my R9800pro in a fan bracket.

...and I'm thinking that I can now position two quiet but good air moving 120mm fans right where I need them.

I have low/moderate noise 70mm fan on my CPU now but a 120mm fan would be preferable. I also like the idea of the fan bracket better than a fan adapter. Question is will the air disperse too much without the latter.

no air quickly spreads with an open fan unless you have a heatsink directly beneath it or a shroud of some kind.
So free fans are best for cooling larger areas like a whole side of a graphics card.

I kind of figured that but if I buy the bracket to cool my video card I might as well see how it does on the CPU.
