High GPU Temperatures

[il0v3tw1cS]

Hello,

I've purchased a Saphire HD7950 3Gb GDDR5 384bit 950 OC Edition and I got some temperature issues. I use to play Minecraft with shaders, a lot, and it overheats like hell. After 6 minutes of gameplay, my GPU temperature rises from 34 degrees to 72 degrees. In idle mode it's temperature is about 33-48. I fiind it a bit strange, especially when my fans kick in at 2000rpms. Is there any way of fixing that?

Best regards and thank you.

Does it reach higher temps in other games? 72 degrees is normal for that card and most video cards in general.

AMD cards run hot. Not sure how taxing minecraft is, but 72c is about right for a medium load game.
Apart from changing fan profiles, adding more fans, an easy fix can be to enable v-sync if you are getting over 60fps.

Just looking at the 72C temp I'd say that is safe. If fans are loud then you can install a useful program that will control the fans exactly as you want. Download MSI Afterburner. It is free software that can be used with any GPU. In the program you can create a fan profile that will adjust the fan speeds based on GPU temps. Very useful.

When the fans kick in and spin 2000rpm does the temp cool quickly?

Ps. The 280x which is basically a 7970 starts to thermally throttle at ~95c.

Well, in other demanding games like Crysis 3, Metro Last Light, Blacklight Retribution, it doesn't get to 70c. It stays at 60-67 after 1-2 hours of play. When the fans kick in at 1800-2000 rpm, the temperature doesn't go lower, it gets even hoter........ If i'd let Mc open, it'll go higher. By the way, my rig is :

CPU: Intel G3220 cooled with a Thermaltake Contac 21
RAM: 8Gb DDR3 1333Mhz Zeppelin No-Radiator
GPU: Spahire HD7950 3Gb GDDR5 384 bit 950 OC Edition
Motherboard: Gigabyte B85-HD3 rev 1.0
HDD: 500 Gb 7200 rpm SATA II
PSU : 850 Watts (I know that it is Ms-Tech, I can't remeber its name)
OS: Windows 8.1 x64
AV: Eset Nod 32 Antivirus 8
Utility: CCleaner Pro
Monitor:Horizon H-W2205STH-CN 1680x1050 75 Mhz

One more thing: on my video card, there is a button with the Saphire logo, I pressed it when my PC was off, just to see what happens and it changed my resolution, dots, lines and all sorts of lines and colors. I turned my PC off, pressed it again and everything is back to normal. What does that button do ?

Another thing: I have got a very bad case, I got no option of doing cable management, but i tied them up at the top of the case. Does it affect the performance/temp ?
PS: I don't have dust in my PC.
PSS: Sorry for any english mistakes. It's not my mother tongue.

Create a fan profile using MSI Afterburner.
No idea what the button on the GPU does. But I wouldn't push it unless you know what it is.
Vacuum the dust out and use wipes.
Bad airflow affects the temperature inside. Try to improve airflow by more fans or less blockage.
The GPU temps in other games seems fine. Are you saying the fan doesn't run until it gets really hot? Fans should always be running but at low speeds unless higher speeds are necessary.

Well, the fans run permanently but when they kick in at 2000 rpm they don't cool it down...that's the issues.

but that is how temperature controlled fan profiles work
The hotter the chip gets the faster the fans will spin, eventually it will stabilise at certain temperature and rpm levels if the load stays constant. It will only drop in temperature once the load (and heat output) drops.

Oh, ok. So it is normal. I was wondering if the card is stable even at 70-80c . That temperature rising scared the heck out of me. I thought I might have broken something.

When the GPU is stressed and hot it will ramp up the fan but temp might not drop, instead it will keep it from going up.

At 2000rpm, what XX% fan speed is that?

 

[il0v3tw1cS]

At 2000 rpm,I it hink that's about 65-75%.

Is the problem gone now?

 

[il0v3tw1cS]

Well, I haven't checked this for quite a while. I've cleand my PC and modified a bit my desk for a better airflow. Yes, the problem is gone.
