GTX 470 Cooling Issues

post #1 of 8
Thread Starter 
Recently I noticed my temps were abnormally high on my EVGA GTX 470. It's about a year and a half old, and up until now, it has never idled past 50C with the fan spinning at 40%. I downloaded EVGA Precision for the first time since I got my SSD (about three weeks ago), and when I checked my temps, my card was idling at about 70C, so now I have to keep my fan at 65% and I only get the card down to 55C. I pulled off the shroud and dusted the card for the first time, but alas, nothing. Anyway, any ideas? Is this a voltage problem? I know the GTX 4xx series has horrible temps, but this is a bit much.

Maybe a bad temp sensor? You could also try a different program like MSI AfterBurner.

Besides clogged heatsink fins and high ambient temperature, one very common cause for high idling temperature is the card's non-downclocking.  This non-downclocking from 3D clock to 2D clock is usually due to either a background application has been triggered and it is preventing the downclocking or two monitors (of different resolution, especially) connected to the graphics card.

 

I see in your sig rig that you have two displays connected:- Hanns-G HH-281 at 1920x1200 and a HDTV at 1920x10809(?).  I strongly suspect this is the cause.  Do you have the 2nd display hooked up only recently?

 

To overcome this, use Nvidia Inspector (a free utility) to tweak.  Read the thread below:-

It could be the fermi degrading syndrome caused by operating in the long term heat these cards produce. If I were you I would RMA the card if at all possible. trust me there are plenty of EVGA 400 series card users like yourself and myself included who are having the same issues. Just do a quick google on their recent 400 series cards and how the users are complaining that their cards are degrading over time and overheating.

Thanks for the link.. I had been wondering what the deal was and why my 2nd card was never dropping down to the lower P state.

So Windfire, you were totally right. I added the TV recently and as soon as I unplugged it my temps went back down. While that program looks great, I didn't like the inconvenience of either adding all of my games in there, which would take a while, or enabling and disabling it every time I go in and out of a game, I moved the GTX 470 down one slot so it could breathe and plugged in an old GTX 275 I had lying around to which I hooked my secondary monitor. My temps on the 470 are back to normal and the 275 temps are well within good idle temp ranges. I think I am going to pick up a cheap used graphics card from a friend to replace the GTX 275 as my permanent second monitor GPU.

Your solution is also good.

 

So, your GTX470 is now in the middle (dark blue) slot and the GTX275 is in the top (dark blue) slot?

 

The Asus P6X58D Premium can do x16/x8/x8 and x16/x16/x1.  I would suggest the GTX470 remains at the top (dark blue) slot to take full advantage of the x16 speed.  In order to leave maximum breathing room for the GTX470, the 'cheap used graphics card from your friend' will sit in the bottom (white) slot utilizing x8 under the x16/x8/x8 arrangement.  This, of course, will require that 'cheap used graphics card' to be single slot as the HAF932 has only 7 expansion slot openings.

 

Example of cheap single slot card:- Zotac GT210 (US$15 after mail-in rebate)

Windfire, your powers to know exactly what is happening mystify me again. I was preparing to pick up a single slot card and put it in the white slot on the bottom running in x16/x8/x8. Also, yes my cards are currently: GTX 275 in the top dark blue @ x16, GTX 470 in the middle dark blue @x16.
