Pretty much one GPU is not too hot while the other is 15-20C hotter..

From the looks of it..since one card is actually blocked and not getting a good air flow..i am wondering ways to get a fan and have it blow air across the middle.

I Was thinking of maybe from the front side (power connection side) and getting a fan to blow that way..or..from the side..if i do it from the side i have to make sure its done in an angle otherwise the hot air pumped out from the top sides..gonna get reblown back into the gpu..

Since the cards dont have seperate 2d clock down like the gtx..its running all the time 500/600..and i do have my pc on pretty much all the time..not running games but it does heat up. I am wondering how to pretty much get a good air flow going on in the gap..atm the hot air is pretty much sucked into the gpu from the other card..so there is a big heat difference between the two.

I wonder why nvidia didn't put the 2 gpus on the other end..and make it so that the air is sucked in from the sides and then blown out the back...

The heatsink on the GX2 is as cheap..or cheaper than the one you see in the GT :/..one reason i avoided GT was the crappy/dodgy looking heat sink..same goes for the gx2..sadly after waiting 2-3 weeks with 2 dead gtx cards and asked to wait another 2-3 weeks was too much for me ><..

Anyone got any tips?

PS: Side case is open.

Idles g1(53)-g2(49)..but when in action the difference becomes arround 10-15C.

ATM there is hardly any way to get air through the gap for me.

My case is a Antec 1080AMG. And i do have a intake up in the front...kinda useless because i do have the side case open..

If i put the side case on and use the side fan..its gonna blow air into the gpu..near the gap..but then the problem is that the hot air that is getting pumped out from the gx2 sides..will get blown back..unless i get another fan and drop it right below the gx2 exhast air area and have it blow it up...

my head hurts >< hope people get what i mean lol:D

Get the VCool, PCI fan which exhausts hot air.

I had two problems,

1) cooling the dual 7950 cards
2) cooling the passive chipset heat pipe of my Asus An8-32 SLI board

Here is a shot of where I placed a good 120mm fan
http://www.fpsadmin.com/images/case.jpg
http://www.fpsadmin.com/images/case2.jpg

This setup keeps my video cards at 65degrees under load and my chipset temps around 40 degrees under load.
My CPU is a constant 38\40 under load

As you can see, the front of the case does not look very nice right now. I'm waiting on some perforated aluminum to make a screen to block that ugly hole. Function over nice right now.

My office where this box is located with central air is about 85F or shall I say "room heated by Nvidia".

I'm looking at the ICE HAWK from coolit for my 7950 cards to lower the temps and keep my office under 75F

Erm..i dont think thats gonna help..if i think what it is..its a pci slot cooler..i remember seeing those arround..it wont help in my case because what i want is a way to blow air to the middle gap between the two cards in the gx2...so i can get some airflow going inside the gap..atm one card is getting hot air from the second pcb..and i think the backside of the pcb does get very hot near the gpu..and that hot air is taken into the other gpu via the fan and that is hot air ><...not much if a difference in idle..but in load...

The best i can think of is to get a very small fan or 2...and point them from the power side and the other side..and blow air in..

I hope some good aftermarket cooler comes out....dont wanna go watercooling.

****..quad sli must be like really hot lol ><. For me..my motherboard and cpu are fine..its winter in AUS so that isen't a big problem to me so far..i got the same readins as you say about the cpu/chip during load.

Also I noticed that Rivatuner and the Nvidia CP only show 1 GPU temp..and it seems like the average temp..if you use everlast you can see all the gpu temps (in your case 4..in my case 2)..and during load big difference in the two..during idle its ok.

I was thinking of similar thing to do...find a way to mount it near that area..and blow it across the gap..this should allow a better air flow in the gap..

Here is a shot of the Ice Hawk I took at E3

They also showed this attached to a Dell quad SLI box in the back of there booth (sorry not picks of that)

Here is their product slick http://www.fpsadmin.com/images/IceHawk.pdf

Whats Everlast?

Whats Everlast?
It's Everest. You can get it here:

BTW, I did something similiar to rudedog. I added a fan that I strapped to the case right in front of the cards so that it blew some air through all of them. I did that b/c one GPU was about 10+ degrees higher than the other 3 so I was trying to fix that. It worked out pretty well and dropped all 4 temps. I placed my extra fan in front of the regular front intake fan but the extra fan is just an inch or less from the 7950s since it's strapped to the hard drive cage. Basically, it looked like I had two things keeping one of the GPUs from getting some cool air. The first was having a hard drive placed right by the 3rd GPU. So I moved it. The 2nd was that the rails of the hard drive cage block some of the air flow to the cards. So, I added the 2nd fan on the outside of the drive cage to help draw the air directly to the GPUs.

What he said ><.. Then why did he say Everlast? Also, i have Everest home edition and there is no temp monitoring software with it.

There is still no temperature software for the free version.

The free version has Temp Sensing.

You can always download nTune. It keeps track of the temps. I simply mounted a 120 mm fan over the side of the cards. It has trimmed 15C off the middle card.

Yeah, Side fans are great cooling for cards, I installed on in my panel since theres no premade panels for my case.

ntune seems alright but it does a LOT more than just monitor those two GPU temps and that's all I really care to use it for. Seems a bit overkill if your primary purpose is singular.

Yea your right, only i had to look in the manual about it, and it says Dell has some other sensor chip which doesnt work with Everest, thats why it doesnt show up on the program.
Doesnt N Tune only work with Nvidia mobo's?

The little fan I put here helps pull some of the hot air out. The air that comes out of this fan is super hot, you can see it on the left hand side of this picture. Its a coolermaster fan that came off of a NB cooler...

Is there a newer ntune than what is on nvidia's site?

EDIT: Wow jAkUp nice pic. That Zalman nearly touches the bottom of your case though. Zoinkies.

It was just released on June 13th. So, there is no newer version and it was written for NVIDIA chipset based systems. And, it changes some items for the video card, as well. Download link (http://www.nvidia.com/object/ntune_5.00.08.06.html).

Wow cool way more up to date version. Does it load anything on startup?

Noticed it also says it needs some vendor specific files. Not sure what it wants there. Maybe I'll just wait for NVidia to integrate GPU temp monitoring (both of them) in the driver. I would be loading this util mainly for that functionality.

Everlast is a company that makes boxing equipment

or

Everlast is an ex-member of Irish House of Pain, and current solo artist


rudedog, is that one of those upside down lian-li cases? asus heat pipe cooler, doesn't really work upside down. members on hardforum.com really recommend getting a different cooler if you decided to go upside down

I have the coolermaster 830 with 3 120mm fans blowing air in from the side! it r stay mega cool :)

I too have a 830. The option for 4 80-140mm fans (or minus 2 and add the crossflow fan) is really handy, probably the best case for Quad SLI.

I don't have my side fan bracket installed as the system seems nice and cool with just the air moving through the front, rear and mess sides.

I get about a 2 degree difference, at idle it's about 41 / 43, after playing COD2 for a while it gets up to bout 50 /56.

My setup is a little unique.

Keeps my mobo and cpu rather chilly also.
