***The Official NVIDIA GeForce GTX 570 Overclocking Thread***

I've got 570SLI in a HAF 932 too.
Although I've not used the PC much since I fitted the 570s a few months ago (around the time VAT went up to 20% if memory serves) because the CPU cooler is rather loud and it annoys me (CM Hyper 212+ but with Akasa Viper fans PWM controlled. Trouble is they don't have the rubber anti-vibration pads so as well as Vipers being very loud they also vibrate slightly). I've got a Silver Arrow waiting, I've just not fitted it.

Anyway, my point here being that I was rather hoping the 230mm side fan would do a nice job of keeping the 570s cool. Are you finding that this is not the case?
 


Thats with the new drivers installed, I have noticed the cards running a bit cooler.

At the moment the case fans do well at keeping all the innards cool, I Just want to swap the 230mm fan for 4x120mm ones as it'll be basically twice the size of the current fan.
The temps at the moment really don't have anything wrong with them but I'd just like to make it that bit cooler :P

I've also got the silver arrow in the case, it's almost silent and does a Very good job of keeping the CPU cooler and doesn't vibrate atall.
 
There's very little difference in the area of 1 x 230mm fan and 4 x 120mm fans.
The biggest difference will probably come from the 120mm fans spinning faster (and probably louder).

1 x 230mm = 415 cm²
4 x 120mm = 452 cm²
But then remember that 4 x 120mm fans mean 4 dead zones which probably total more than the 230mm dead zone.

I have wondered if it's worth doing a few times myself though.
 
hi, i was thinking of buying a MSI GTX 570 Twin Frozer III but only one. Just wandering if i would be able to max out settings on games like Skyrim and Rage with one and what sort of fps i would get from one if i OC'ed it
 
I've found out that each of the 230mm fans in the case move around 92CFM of air whereas one of these these will move around 57.5CFM so 4 of them would move 230CFM.

So for a small increase in surface area and possibly noise airflow in could be improved over 2 fold. If I do this (I think I probably will at some-point) I'll also get a fan controller so I can ramp them up when gaming and have them nice and quiet when not needed.

sorry i'm a bit new to this, SB? BD?

SB = SandyBridge (Intels current offerings)
BD = Bulldozer (AMD's offering that's due to be released sometime next month) :P

Also I have 2 of the cards that you'r looking at, they're very good and overclock well (look at my previous posts) Depending on your budget though I'd try and stretch to SLI

SLI being EVGA cards? and my budget isn't actually that high. How much do you think the Bulldozer bundles will be?
 
SLI is when you use two nVidia graphics cards at the same time in one motherboard. it's much more cost effective to get two mid range GPUs and SLI them than it is to get a rip off top end GPU by itself.

the AMD equivalent of SLI is crossfire which is pretty much the same thing, but it scales a bit better afaik

Yeah, but I own 4 Apaches and they are loud on full whack and if you reduce them then you lessen the airflow. Still, it is an option.

Are your 570s reference design?
Do the reference cards overclock well or are there problems with some VRMs not being cooled adequately on reference design cards?

I'm very tempted by the EVGA 2.5GB 570s, but they're not reference design so not sure how the cooler would affect temps of the cards and overall case temps (since they don't look like they exhaust out the back)?
Does having 2.5GB of memory affecting overclocking in any way (as it can do with CPUs)?

My cards aren't reference. The cooler on them is very very good (MSI Twin frozr III) as for for overclocking and the cooling I'm not so sure on the finer points but everything's working well for me :P

Can anyone tell me if this is a reference design gtx 570? I've purchased one but would like to know for sure before it's shipped, cheers.

edit/ would like to know as voltage control seems to be locked on non-reference cards.

Non reference Judging by that review.

I had a bit of trouble gaining voltage control on my cards (They're Non Reference) But I eventually got control with nVidia Inspector.

That review is of the Phantom which is pre-overclocked version with custom cooling, the one i've ordered is just a vanilla Gainward GTX 570, still can't be sure if it's a totally reference design though. I'll soon find out I suppose, will be disappointing if voltage is locked but not the end of the world as they seem to clock pretty well on standard voltage.

The one i've ordered looks like this:
