It has been almost about a year since I last purchased my new xfx 5870 video card from Newegg last september. The first few months, I had no problems with the video card. Now that I try to play any game, the card overheats up to about 70C and the fan speed increases up to about 65%. I tried running various games with all low settings and all high settings, but the card still get as hot and the fan speed still increases up to about 65%. I have not overclocked or manually set the fan speed of my video card.

Here are the specs of my computer (none of them are overclocked):
AMD Phenom II 965 Black Edition
Asus M4A89TD PRO
Corsair 650W TX
2x2GB G.Skill Ripjaws 1600
XFX 5870
Windows 7 64bits

I have already contacted customer support from the xfx site. This is what I said:

It`s been almost a year since I bought this video card from Newegg. The first few months when I started using it, everything was fine. I was able to play most games on high settings without any problem. A few months later, problems started coming up with the video card. Now every time I try to play a game in full screen, even with the lowest graphic settings, the temperature of my video card rises up to about 70 degrees Celsius and the fan would start to get really loud no matter what game it is. I was wondering if I could get any help or advice on solving this issue. I also haven`t overclocked my video card or anything.


This was their reply:

Hello Ying, thanks for the message. 70C is actually really low for these cards. We expect them under full load to reach the high 80`s or low 90`s C. The fan is supposed to speed up as the temperature rises I believe around 70C its only running around 35%. What your describing sounds normal. William.

I personally don't think that this is normal because every time I try to play a game, the fan speed of my video card gradually increases up to about 65% tops. Also sometimes, the games stutter or lag while I move around. If I could receive some advice on how to solve this issue it would be greatly appreciated. For the record, I have not used up the warranty yet, so maybe I could send them my video card and get a new one, but that would my last option if nothing turns out right.

What case are you using? How many cooling fans? What heatsink-fan (HSF)? How old is the power supply? A little more detail, like this, will help. Please clarify.

70c is usual for a GPU, they are safe to around 95c, and max out at around 100-110c.

My HD 6870 is at around 70c at %45 fan speed, so you should be fine.

Case: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The case was bought along with the power supply the same time I bought the video card. All the components are using stock coolers.

I don't really believe there is an issue...my graphics card is at 70C every time I play, and that's under load, the highest I've seen my GPU go is 73C

Temps are actually ok as indicated. Are your drivers current?

Is your side fan working and is it sucking cool air into the case and blowing into the GPU/CPU area?

It's possible after one year of use enough dust has built up to reduce your cooling effectiveness. I would remove and clean the case filters first (I see you have at least one). Then try increasing air flow into the case by adjusting your fan speeds. What you're seeing may be the result of the ambient temperature increase (because of the phenomenon most of us call "summer time").

Finally, you could try removing the 5870 and cleaning its cooling blocks by either blowing pressurized air or disassembling it. Some people even recommend re-applying the thermal compounds (with something like Arctic Cooler 5).

Hope this helps ;)

The video card fan is facing down and my motherboard is help up by my tower (not flat, otherwise the video card fan would be blowing sideways)

I disassembled all my computer parts, cleaned them, and put them back together, hoping that I would see a difference, but nothing changed.

Try testing the GPU in another machine if you have one available.
