View Full Version : Nvidia 460 temp and fan speed

My 460 GPU is running rather hot at 55 deg but the fan speed runs at only 35%. Is there a way to control the fan speed and brings down the temp?

If I were to add another case-fan, should I position the fan to blow in or suck out?

At present, I have 2 fans drawing air out and only one blowing in from the front.

IIRC, Riva Tuner will let you control fan speed.

That, and 55 is quite acceptable. It'll automatically bump it up if the temperature was too high but it's happy to keep it lower / quieter :)

Is adding a case fan to improve air-flow a good idea?

Potentially, though not specifically. Is that idle, or under-load temperature?

under about 50% load temperature.

I have 2 case fans blowing air in, one above the cpu fan and the other above the graphics. When idling the cpu sits around 28 degrees and goes as high as 48 degrees at 100% load. The GPU idles around 30 degrees and goes up to 50 degrees when gaming.

under about 50% load temperature.

That's not CPU load, but game-load which is stressing the GPU, correct? Just wanting to clarify :)

It's fine, 460's thermal limit themselves at 99 and anything under 80 during full load is unlikely to be a problem. Download furmark, run it for 5-10 mins or until the graph flattens out and see what the worst case scenario looks like. Mine hit around 75 degrees with good airflow when I had 2 in SLI.

Incidentally unless graphics cards are faulty you can take a fan running at 25-50% speed to mean the manufacturer doesn't consider that to be hot.

Might look up furmark for my HD6870 when I get home :D
I've seen mine get up to 77 degrees. Should reapply the thermal paste again and give it a real *good* cleanup.

I confess to not really testing anything when I built new PC's or upgraded parts in the past.
But after the problems with my last 2 builds I tend to do a bit of stress testing when new now to try and be sure it's all good. Probably something any good tech would do, but us amateurs tend to be a bit sloppy :) (OK I am a Tech, just not a PC one :))

generally I use;
Prime 95 + realtemp to stress test CPU
Furmark to test graphics
Memtest to check RAM

there are a lot of tools around, that's just what I use.

I keep Speccy open on a second window while playing DotA2, but I've got everything at *max* so I figure if I can stress with something dedicated to the task, it may push things up a bit higher. Or, it may prove that the card is OK and won't be overheating under any stress (Hopefully).

Appreciate the heads up :)
