I have two 7800 GTX's running sli, and they fuckers raise the case temp considerably, i am thinking about putting vga coolers on them (arctic cooling silencer rev 3) but i was wondering if anyone knows of anything better on the market made for SLI.

you could take one out and give it to me that would lower the temp some. But really what are you running that you need 2 7800s

2/2/2006 9:19:17 PM

side case exhaust fan. exhaust, not intake. And build a cage from some matte board or chipboard to cover the area above, below and to the back of the case around the cards. Leave the front side (back end of the cards) open for intake air from the front of the case.

Are the temperatures approaching dangerous levels? If not, don't worry about it. Those are top of the line cards and they put off a lot of heat. Unless you're seeing GPU temps above ~85C, I wouldn't worry about it. Is it making the case too warm for the CPU? Noen's suggestion of the side exhaust fan is a good one. Top exhaust fans work well too in lowering the overall case temperature.

i rebuild my pc every couple of years and this was the most recent rebuild. 2 gigs of corsair ram, with funny looking lights on them, badass asus mobo, 3.8 p4 bout to be running at like 4.5, 2 7800's , thermaltake beetle for the cooling, it rocks. processor runs at like 30 and cards run at 55 idle, tryin to cool them down. im a big fan of splinter cell, pop, doom, quake, fear and shit like that. running at max settings and max resolution the cards do it's magic.

the arctic cooler silencer rev 3 will blow the air off the cards out the back, which will lower case temp but it won't help cool the cards down will it. somebody get a pic of that thing and post it here. i can never figure out how to post pics right.

My case has a duct that runs from between the video cards to the back of the case.

I don't even have it installed, though.

Pic as asked for

2/2/2006 9:47:09 PM

cards at 55 is FINE dude. GPU can handle up to 135C

2/2/2006 9:49:48 PM

Uh, 135C???

2/2/2006 9:51:46 PM

plus he said 55 idle, i wonder what they run at under load

2/2/2006 9:59:13 PM

on my nvidia GPU temp settings it shows a 135C threshold, warning at that temp.

GPU not ambience, that make the difference?

2/2/2006 10:01:32 PM

! Yes, the nwer nVidia GPUs are designed to run real fucking hot. In fact 55C is a pretty good idle temp. My 6800GT idles in the upper 50C range. I run near 70C under load.

2/2/2006 10:02:44 PM

yea i know it's limited at like 140 but when running games my case temp goes up cuz of the cards like hell. like 120 f

2/2/2006 10:06:36 PM

i mean for cards at 140 c , and case usually idles at 70 f

2/2/2006 10:07:05 PM

so as i said, i'm not worried about cards overheating, just the case being warm.

2/2/2006 10:07:37 PM

by the way thats not the right pic i dont think, it's the version for the ATI cards.

my bad

2/2/2006 10:20:03 PM

while we're talking about cooling, thermaltake beetle has multicolor led flashing in the front, does anyone know of a way to lock in the colors?
i got all blue LED set up and 7 different colors are annoying.

So you're saying it's safe for a video card to run at nearly 300 degrees farenheit?

2/3/2006 12:28:32 AM

ahahaha, of course it's not. it can but that still sounds like a fucking terrible idea. even if the GPU can handle temperatures that high briefly, having them around 130 for extended periods of time would doubtlessly cause problems; if not for the gpu itself, but for other components on the card and in the case.

2/3/2006 12:30:54 AM

Yeah, I know.

I'm just saying.

Just seems fucking high to me.

2/3/2006 12:46:50 AM

yeah, I was agreeing with you. I was just laughing at the idea of a component running that hot all the time. I mean that's a lot of power dissapation too.

2/3/2006 12:52:29 AM

under load, my cards run at max 60 celsius. that's still pretty hot to me. even if save threshold is at 140 celsius. my roommate has that silencer rev 3 on his card and it keeps it at about 55 under full load. he's only got 1 card though, so mine will never get that hot since each does 1/2 the work. assuming i put the coolers on them.

2/3/2006 11:41:47 AM

^Do you not understand SLI? The cards aren't doing half the work, you're getting twice the power. Plus, from what this thread discussion has revealed, your cards are working normally and within their intended functional temperature range.

2/3/2006 12:17:21 PM

This may be a stupid question, but with SLI, is each card just doing half of the picture, or is it something fancier than that?

2/3/2006 12:42:57 PM

^ Basicly, yes. There are a variety of articles out there that explain all the gory details. The GPUs split the rendering workload. Therefore, one GPU could only be rendering 1% of the frame if that 1% area represented 50% of the total rendering workload for the entire frame. Supposedly, there's a program or something in the driver that will let you see what part of the frame is being rendered by each card.

Interesting.
