How to lower temps in my Cooler Master Cosmos 1000

Hello. I have finally put together a new gaming machine. I am having problems cooling the video card. It runs as high as 88C when playing Crysis or running a video card stability test. Sometimes I get artifacts during Crysis. I am assuming the high temp is my problem. I have installed all the fans that can go in the case. And installed the video card duct also. Is their a way to modify the case to increase cooling capacity without violating the warranty? Or any other information I should know? Thank you.

COOLER MASTER COSMOS 1000 CASE
EVGA GX2 SUPERCLOCKED EDITION
2 RAPTERS 36G
1 WD CAVIER 500G
MUSHKIN RAM 2X2G
COOLER MASTER 1000 WATT POWER SUPPLY
E8500 CORE 2 DUO
XIGMATEK HDT-S1283 120mm Rifle CPU Cooler

By the way the CPU temp is 65C under load.
 
So, do you have one fan at the back of the case, three on the top, one on the bottom, and a fan for the hard drive cage, or just the stock fans that came with the case (one on the back, two on the top and one on the bottom)? Overclocks/ambient temps?

I would suggest removing the air duct because most reviews that I saw for the case said that the duct basically had no effect on temps. Your best bet may be to just break out the dremel and make your own 120mm fan mount/air intake on the side of your case. I have no idea if that would void your warranty on the case or not. But I'd rather void my warranty on a case than cook my components.....

Well, I removed the duct and it lowered the temp of the card as much as 5 to 8 degrees. I think the exhaust from the card, was short cycling back into the inlet of the duct. I just ran the video card stability test with no problem.
Still, doesn't 80C seem too high? Is this normal for this card? Thanks for the idea.

Edit:By the way, this case only allows one fan on the bottom, one over the hard drives, two at the top, and one in the rear.
 
Do you have a side fan over the GPU area? That should drop temps a lot. If you need to, drill a 4.25" hole there and mount a 120mm there. It WILL void your warranty on the case.

No side fan. But I can easily install one like you suggest. I have emailed EVGA support. If they tell me these are normal temps I will install one anyway.
 
I don't think that 80C is really that excessive for video cards in this day and age, especially if you are using the stock HS/fan. Card manufacturers have come to understand that users don't want a loud card in their system, with higher temps being traded off for less noise.

My HD4850 w/ stock cooling gets into the mid 80s under load and my case is definitely more windy than your Cosmos (I have a Cosmos S, which has a huge 200mm side panel fan right over the card). I am planning to replace the stock HS with an Arctic Cooling aftermarket solution because there's no reason I should have to deal with temps that high with the amount of airflow that my case generates. It boggles my mind when I see a post where a user has dropped their card's load temps by 30-35C just by replacing the card's HS/fan with an aftermarket solution that is no louder than stock. Why can't ATI or NVidia design just design a cooling solution that allows their cards to run both cool and quiet? I find that especially annoying when the aftermarket scene can do it for US$30 or less.

Anyways, Good luck with EVGA support, but I would guess that they will tell you that temps that high are normal for the card. You could also try manually controlling fanspeeds. I haven't had an NV card for a few years, but I know that for some ATI cards there are ways to create custom fan profiles using 3rd party software (I could do so with the X800XL in my old rig, may she rest in peace).

Got a quick response from EVGA. They said to run their utility to check temps and not CPUID hardware monitor. Temp readings were about 5 degrees less. I have no problems with my computer when I have the side panel removed. I suppose I chose the wrong case. Anyway I will look into adding a side panel inlet fan and an after market cooler. Thanks.
