EVGA 480GTX SC running too hot

post #1 of 6
Thread Starter 
Hey all... I figured I'd just go ahead and start my own thread.
I've been on a laptop for the past 10 years, spend the last 4 playing WoW.
Every time there's a patch, WoW eats just a little bit more cpu/graphics power.
My Gateway P-7811FX just isn't up to the task any longer.
I put together a pretty simple/cheap rig that will be plenty for me.

Asrock Extreme4 MoBo
Intel i5-2500k running at 4.2Ghz on CM 212 Plus (nice and cool!)
EVGA GTX 480 SC
16GB Kingston Hyper X RAM
Intel 128GB SSD
BFG 550W PSU
NZXT Phantom White case
23" Samsung S23A550H

Absolutely LOVE this setup. Only downside I'm seeing som far is my GTX480
running World of Warcraft, and moderate settings, at 80c!
I fired up Furmark @ 1920x1080 and ran the burn in for about 1 minute.
Temps climbed to the mid 90's.
I've read a lot of the posts in 'The Mod' thread, and have ordered a plate with fan option from
Dwood. I'm planning on going the LC route.
That said, I just read all of the posts in the "Modding/heat spreader" thread.
I've pretty much convinced myself that either the TIM between the heatsink and
IHS is crap, and/or there is a gap or crappy TIM between the IHS and chip.

I'm going to go ahead and remove the factory heatsink, pull the IHS and see what I've got.
I'm going to try to put it back together without the IHS installed and see if there's a gap between
the heatsink and chip. At this point, I'm not sure if the heatsink it perfectly spaced to sit on top
of the IHS, or if it will sit down far enough to make direct contact with the chip.

I did a lot of searching and wasn't able to come up with an answer, so figure I'd give it a shot
myself and post my results here. I'm camera-poor at the moment, but for online pics, the antique
Fuji I have will suffice.

I'm not really terribly interested in OC'ing the VC, but would really like it to run cooler.

Any/all comments, thought, criticisms are welcome! wink.gif

Could be that you have a high vid 480, check that.
If you do then you can probably get away with dropping the voltage.
Most 480s can run stock speeds in the .96-.98v range, mine could.

Don't run furmark and crank the fan speed up.

Hi Grunion! Where would I find that info... I've got GPU-Z opened up and don't see that info.
I know next to nothing about OC'ing GPU's. Is the GPU OC'd with a specific app?

Thanks!

Check the 3 threads I'm linking, 1, 2, and 3.

Been so long since I've owned a 470 or 480 that I couldn't tell you offhand how to determine your vid.

Wait a minute, pull the IHS, don't do that.
Fermi runs hot, just get the voltage in check, replace the stock TIM, and create an aggressive fan profile.

When I had a GTX 480 I used MSI's Afterburner tool. Could not have been easier. I watercooled mine though, so like Grunion said create an aggressive fan profile.

If you do 'The mod' use the best tim you can swing and don't forget to blow air over the rest of the card.

Good luck!

Thanks FoW... I just checked out the Nvidia OC forum, saw afterburner mentioned and installed it.
As soon as I ran it, my temps dropped big time, from 80c down to 64c in about a minute.
My frame rate in WoW went from 120 to 30, so I'm not sure exactly what it changed, but it did
something!
I'm about to head to bed, but I'm going to check the TIM tomorrow see about just leaving the IHS off.
Once I get it back in, I'll see what difference it makes and then start playing if the temps are good.
