Radeon 6990 inside Raven RV-01 cooling help

post #1 of 11
Thread Starter 
I have a reference 6990 inside an RV-01B. As you all know half of the hot air generated by this card is exhausted inside the case. That doesn't play very well with the rotated airflow design of this case. So I've been looking into some options.

1. Block the exhaust slots on the front of the card to "force" all the hot air to go out the back (or in this case, top) like it should.

2. Create an air-tight tubing/vent system leading from the front exhaust of the card to the outside of the case. Thing is I have no idea how to do this.

I had placed a flap of sorts which leads the exhausted air into the CPU area of the case, so the card doesn't suck in its own hot air. But that in turn caused my CPU temps to rise so much I had to turn HT off.

Right now I have some hose-like tubing I can use, but no idea how to funnel the air into it to get it out. That is, if I choose option 2.

Ideas?

i would say that rotated design is good thing because hot air raises up so if you have bottom intake it should push the hot air up from the case.
some gpu coolers like prolimatech have problems with rotated design because heatpipes are rotated down and fluid inside the heatpipes must go down which can be problem

So, this continues from your last thread:-wink.gif
http://www.overclock.net/computer-cases/1013522-silverstone-rv01b-w-cooling-issues.html
(Have you read my post #13 there?)

Have you installed everything I proposed except the DeepCool Xfan 5? If so, this is likely the reason why your CPU has higher temp as all the hot exhaust is now sucked through by the H50 fan-rad.

Hey Windfire. Glad to see you're still here helping people like me out. smile.gif

I did buy the DeepCool Xfan 5 and follow your proposed solution, however this left me with no option but to remove my X-Fi on the PCI slot due to it being taken by the 6990. frown.gif

I tried living with onboard for a while, but I simply had to put it back in. Purchasing a newer, PCI-E x1 sound card is not an option at the moment due to budget constraints I'm afraid.

So right now I'm trying to simply direct the exhausted air completely out of the case without interfering with other components, if that is even possible. smile.gif

Also I owe you some rep, which I will be giving now.

EDIT: Didn't see followup post #13. I'll try that later and let you know what happens. smile.gif

EDIT 2: Hmm, being a former P35 to P45 user, I noted significant increases in FPS once I moved from PCI-E 1.1 (2.0 x8) to 2.0 x16. And this was back on an HD4870x2..

OK.
Try my 'Plan B' in post #13 to see if it works better.
If it does not, I still have a trick or two up my sleeves that I can pull out for further refinement.smile.gif

Well I tried Plan B, however I did lose a significant amount of performance by moving to x8, mainly on the minimum FPS department on demanding games (Crysis 2 DX11, etc.) frown.gif

I really wish there was a solution wherein the card could be left on PCI-E slot 1 though..

Moving the HD6990 back to slot 1 is not unthinkable. If this graphics card is given top priority, then perhaps other components need to move out of its way.

See pic below for Plan C. The H50 fan-rad might migrate to 2 alternate locations to receive fresh ambient air:-
a) Front position occupying possibly three 5.25'' bays, or
b) Bottom position

Front position is possibly easier and better of the two. For bottom position, the hose length might not be enough and you will need to mod to extend the length. And, some HDD racks need to be removed for better upward air movement.

With this arrangement, the top case exhaust fan is now free to extract all the hot exhaust of the HD6990. And the Xfan is not needed.

9600GT and the sound card reside on the left most PCIE slot and PCI slot respectively.

This actually looks quite promising. smile.gif

I didn't think of moving the rad to the front. Gonna have to think about how I'm going to mount it though. And yeah, it's definitely not going to reach from the bottom slot unless I mod in new tubing.

I'll give it a shot sometime tonight or tomorrow and let you know what happens.

To give you a head start, you can use simple + cheap zip ties or elaborate + 'expensive' brackets (eg UN-Rad...see the 2 pics below for example, showing a 240 rad but the H50's 120 rad should be easily mounted).

Hmm, well I actually managed to place it at the bottom intake, and the tubes did indeed fit (though at a stretch). I'd assume this would provide better CPU temps as compared to the front mount, as the front of the case would be closed shut with the door.

So far my idle temps are looking better than before. Going to play a few hours of Crysis 2 or Aion and see how high that gets me. smile.gif
