Just to clear things up:

There is no dust in the case, the intake filters are clean, the PSU is mounted with it's intake pointing down, the wiring is very tidy and not blocking the air flow at all, and the case is quite well vented.
2 front intake fans, one rear exhaust. I could add two top exhaust fans if I wanted to.

Ambient temps are what we would consider hot over here, getting up to and above 30 degrees C at some points, but generally around mid 20s. Usually it's cooler than that, I'm sure you have much higher temps on the other side of the pond.

GPU is hitting almost 80C with fan speed at 100%, with 100% GPU load, and CPU is hitting 60C at 100% load, with the stock cooler.

I'm not sure from your original post, if the GPU is overclocked or not...if it is....then that is the reason for the high temps.


/e When OCing, only you can decide when temps are too high. Well, or when the vid card melts.

At 80C with 100% fan speed, I'd say you are getting very close to the upper limit.


/ee The (free) Unigine Valley benchmark is a much safer way to test OCing temps. When running Valley, I try to keep max. GPU temp under 70C. Any GPU, any weather.

many cards have hit 80c on intense load

True dat. 70C is just my preference, for extreme long life of the vid card.

@OP, like I said you must decide, and adjust your OCing to suit.


Here is a whole bunch of Valley runs for comparison: http://forums.d2jsp.org/topic.php?t=68291879&f=188&o=0


/e IMO, you will want to have either of these situations...

1. Max. 80C with some room left, on the fan speed.
2. Max. 65-70C with no room left on the fan speed.

he can check to see if new bios for card exists too

and log voltage and temps to see if its spiking when it doesnt need to be

check to see if fans are actually working on the thing

Yeah it's overclocked with MSI Afterburner. Voltage hasn't been touched but is at 150% power, core clock is 1075mhz (was 1000) and memory speed is 1550mhz (was 1500). But the voltage hasn't been touched.

Also - I only hit those temps playing very intensive games that put my CPU and GPU at 100% load for long periods of time. Other games don't get anywhere near those temps.

Edit: Yes the fans definitely work, they're rather loud when they're at 100%.

All good thoughts. However, it's those times when the game gets even more intensive that you have to worry about. That's why we use the Valley benchmark to test our OCs. Valley will run hotter than any game.

Btw, 150% power means the vid card can raise it's own voltage when needed.

IF, the vid card stays at 80C max., after a Valley run...with some room still left on the fan speed (say at 75% - 80% fan speed), then I would say you are golden with your overclock.



/e You need to allow the vid card some room to save itself, if things get really out of hand.


/ee You need to allow some room for things like, a new game patch, or a heat wave, for example, that puts even more load on the GPU. This is why we use benchmarks to test an overclock. They put more load on a GPU than a game will.

log your voltage and compare to others online and stress for stability you maybe able to lower it which may lower your temps

Just ran Valley to double check the temps. GPU peaked at 75 degrees with fan at 100%. CPU's are low 40's rather than the 60 degrees they were hitting last night but Valley isn't loading the CPU as much.

It's not supposed to. It's a vid card benchmark.

All you need to do now, is set your OC so that the peak GPU temp occurs at say, 75-80% fan speed rather than at 100% fan speed.

I have a Geforce Titan (700 series), it's about equivalent to a 390, but with higher temps.

I am going to run Valley in a moment and post the results. I am not overclocked at all.


Benchmarks with neither card overclocked.
