Overclocking

Here came the really tight test, and something that actually caused us to depart from our standard testing procedure. As you'll see below we actually had to run our fans at 100% for testing which we will definitely get to in the conclusion.

Nobody knows for sure what nVidia planned to get out of the Fermi GTX480 core, but clearly the card has been detuned quite a bit because with maximised fans we got a huge boost in GPU and shader speeds along with the heat and performance gains we'd expect.

Temperatures

Normally for the purposes of fairness we run all our benchmarks and overclocking tests at 50% fans. Unfortunately nVidias reference cooler is so hopeless that within two minutes the card shut itself down, having passed 110°C. 60% fans had the same effect and it wasn't until we pushed into the deafening realm of 70% that our stock card was capable of running our tests.

We'd be very VERY dubious about running at anything under than 80% though and this is largely a fault of the fan which is barely an asthmatic mouse at 50% or below. Earplugs a must.

It has to be noticed that this is nothing to do with ZOTAC at all and solely the fault of nVidia and their inability to tame the GTX480.

Lets move on to the important tests... Some gaming results.

I was aswell if Im honest, just have to hope they get it all sorted with the cash injection from the sales of these cards.Quote

Quite dissapointing really. 5870 is really the one to go for, or 5970, which is faster in some and clocks very well. Perhaps Fermi could be better used as a grill?

I hope the next generation brings something better to the show, because these are too hot for what they give, and when a 5970 is only £50 more, they represent very poor value.Quote

Me wants one, watercooled ofc!

My 280ocx is dammed loud on air but having heard these I couldn't put up with the noise.Quote

Judging by the color of the cooler it seems that NVIDIA can use it to light their own victory cigar. Quote
