HD5750 at 84C! need help

[lkn118]

Hi, I enjoy play games. But the GPU temp is a little bit toohigh, even at stock speed (700, 1150)
Will it shorten my fan's lifespan if I tuned the fan speed to 100% all the time?
And is there any replacement fan for my Sapphire HD5750?
Thanks.

84c at load or at idle?

load 100%, idle 41C

noise is not a problem. but will it lower my fans lifespan if i turned the speed all the way to 100%?
p/s: OCed to 800/1300 at 88C!

100% fan speed will most likely shorten the life span of the fan, why not try 80%?

BTW 88C isn't to bad, its hot but its still safe. If your so worried about the temps then why are you overclocking your card.

100% is a bit much. Your card might take flight. haha. As mentioned above 80% or less may be sufficient. You can only move so much air over that cooler, anything extra will just be a waste. I'd lower it to 80% and see what it reads, then lower to 75% and keep going until you see the heat spike again.

80C+ is fine for graphics cards. My 5870 climbs over 80C in DX11 games all the time. I turned up the fan to keep it under 80C, but it really didn't take much to do that.

yeah...just trying to push the limit of my card.

It was a rhetorical question. Anyway how did you get on with the temps? did you up the fan speed?.

will torture my video card at 800/1300, fan speed 80%, using NFS Shift and Dirt 2, all ultra high. Will post the results later, or tomorrow (its night here)

Nothing thing you could possibly do would be replace the thermal paste on the gpu, i actually did that the other day on my card and got quite a substantial drop it temps, for mid 80's to mid 60's which i thought was remarkable

Did torured the GPU, 100% load at 80C at 80% fan at 800/1300.

This is always an option to try, I totally agree. I actually JUST did this on my CPU and GPU. I got slightly better temps on my CPU. But my GPU is exactly the same as it was before. When I removed the cooler I noticed the paste was properly applied.

Thats absolutely fine, you could always remove the old thermal paste and apply some quality thermal paste like others have suggested if you want to lower your temps some more.

it's always worth trying, as paste is only a couple bucks and possibliy of lower temp and possibly higher overclocks (which i was able to get =]) for like 8 dollars i found it completely worth the try

Actually another option would be to use a 3rd party program, to lower the voltage on your card, just as some keep stock clocks on their cpu's but drop voltage for better power efficiency and cooler temps
