Gigabyte 7870 hitting 85C

IceVip · May 25, 2013

I recently got a Gigabyte 7870, my old one was a 6870 by gigabyte with the windforce x3 cooler and i was pretty happy with it, but the problem with this one is weird, if the card is stock, no overvoltage or overclock, out of the box it does 75C, 35C idle. If i overclock the card at 1200/1250, 1288mV, It hits 85C under full load and locks there(100% Fan usage, custom), would the card underperform or kill itself faster if i use it like that 24/7?

P.S I play alot of battlefield 3/Bad Company 2
P.S2 I've seen 3-4 reviews of this card, everyone is saying that the max temp under full load is 65C..

While those are not dangerous temps, you could improve airflow in your case.
What are your full specs and what are your intakes/exhausts?

I was under the impression max safe voltage for a 7870 was 1.225v.

Well,
MB: Asus P5QL
CPU: Q9550 with Coolermaster V6GT
Case itself is some CoolerMaster, doesn't have a specific name..
Ram: 2x2GB Kingston 800
PSU: 400W 80+ Diamond black

The intakes/exhausts, are none actually, the case is opened, and i had to remove one of the intakes under the PSU because it was blocking me from installing the cpu cooler, that was 2 years ago when i bought it, but still, on the same rig the 6870 didn't have any problems, but this one does, i wouldn't really blame it on the shitty build

You have no intake or exhaust fans? On a cooler with radial fans like the one you are using you really do need them.

Novuake · May 25, 2013

I would blame it on the setup, an open rig is actually a bad idea in many cases. Good chance your PSU is also fluctuating under that high load, causing you even more thermal issues.

Is your Q9550 overclocked?

IceVip · May 25, 2013

Yeah its for more than 2 years stable at 3.6 Ghz, max temp is 60C on first core, everything else is below 60C, 55 usually. under 100% load

Novuake · May 25, 2013

Well there you go, you really are stressing that PSU, that could be causing a lot of jitters in the power delivery. In turn that can be causing issues in power delivery to your GPU, increasing its temp output.
It may sound like its not enough to increase temps, that coupled with a CPU OC and the poor airflow in your chassis.

I am not surprised you have increased temps.

Novuake :

I still have the intake fan but i have nowhere to put it :\

Novuake · May 25, 2013

IceVip :

It will not help if your case is open. The fan will not create a flow in the case.

IceVip · May 25, 2013

Novuake :

Well i can't close it because the coolermaster is too fat.

Novuake · May 25, 2013

I realize that, but do not worry about the temps, they are not dangerous.

If you have money to spend, I would just go ahead and get a new chassis and new PSU. Both of those need an upgrade.

Novuake :

I'll do that thanks.
