Gigabyte GTX 460 1GB (GV-N460OC-1GI) SLI HELP!

[Lindrian]

The Scythe Gentle TYphoons do a 1850  version as well. See here: http://www.candccentral.co.uk/Scythe-Gentle-Typhoon-120mm-Case-Fan-1850-RPM.html  But don't forget that if you are running them at full speed they will be much quieter.

Yeah that ones does 57cfm, which isnt that much considering they produce 28dba of noise...

What do you mean? If I run them at full speed they are quiter? I would have to install 5 of these in my case.

5 sources creating 28dba each result in a total of 34.8 dba. Ontop of that my 2 fans on the CPU, PSU, 2x Graphic cards, and the top fan. I just don't want too much noise.

[Dark Mantis]

Yes but that isn't that loud  considering they would be going at full speed. What do you present fans work out to at top speed?

My 5 120mm fans work at roughly 31.8dba in total. Thats a difference of 3dba. Thats nearly double the noise really... I could add 5 more of my current fans before I reach 34.8dba.

But is that at the present lowest setting?

Yes thats the lowest setting. All 5 120mm fans (and the large 200mm) run at the lowest setting. In total they produce (excluding the 200mm) 31.8dba. 34.8dba is the double of 31.8dba.

I suggest you work out what your existing fans would be running at on the fastest setting and then compare.

Lowest fan speed is enough, anything above that is way too disturbing. Can you assemble a full water cooling kit for my PC? Like all parts or something so I can see if I can work it out.

Parts are:
Antec 1200
Asus PT6D Deluxe OR Asus P6X58D Premium
Intel Core i7 930
Gigabyte GTX 460 1GB SLI
Corsair HX850W
Corsair Dominator PC12800 3x2GB
300GB Velociraptor
500GB Samsung
320GB Samsung

Worth mentioning is that I live in Sweden, so if you find any store than can ship to Sweden that'd be great.

I thought that is what you might say!

Regarding the water cooling, there would only be any point in running the loop from the CPU/ NB/ GPU/GPU/Radiator/Reservoir/Pump. They are the only things worth cooling with liquid. You are still going to need some fans just for cooling the case in general and the radiator in particular.
I would suggest getting some ideas from here:

in fact i have just checked and on this page someone has done a double GPU setup with your case http://hardforum.com/showthread.php?t=760053&page=29 They have made a bit of a dog's dinner of it though.

I have one of these on the way and I've been doing some research.  I almost pulled the trigger on the External Exhaust EVGA reference design, but went with this because of the reviews indicating the external exhaust model was loud.  All the reviews on this card praise it's quietness.  Maybe you could try this with your graphics card

It's not the same card, but a very similar dual fan heatsink on a MSI 5850.  If you read down, the guy tested the card with a cardboard shroud.  It didn't do much for the temperature of the card, but it did slightly improve ambient temps, which may help you with your SLI setup.  I'm getting this card in hopes of buying a second one later and going SLI.  I also have a Coolermaster ATCS 840 coming.  It has no side fan, so I may have to look into a mod for that later.

Cooling on some of these modern graphics cards can be a nightmare! The amount of heat they produce is enough to heat a small home The problem being if you buy a card and then have problems with the heat buildup there is a limit to what you can do without voiding your warranty. Most manufacturers wont allow any modification to the heatsink/fan assembly so you are stuck with the stocker. It is a shame they don't sell a version of the cards without any cooling solution attached and allow the end user to configure their own. It would also be cheaper for the likes of us that like to liquid cool as we wouldn't be paying for some nice, pretty fan that we just rip off and discard.

My CPU is overclocked. The graphic cards have a mild factory over clock. The model number is GV-N460OC-1GI

I have the exact same card, albeit just a single card (not SLI). Using FurMark to stress-test the card (about as much as is possible with software), mine maxes out at around 70C. Running normal games, it rarely goes much above 54-55C. And this is with it overclocked beyond how it comes from the Gigabyte factory (800MHz GPU, 1000MHz memory, versus 715/900).

This is in a mid-tower case (Cooler Master Elite 370) with a single 140mm intake fan and 120mm exhaust fan, both fairly low-speed. There are a lot more fan mounting points in the case which I'm not using, though (and their open grilles may be contributing to cooling regardless of the lack of fans). The system is nearly silent, even when the CPU and GPU fans are running at top speed.

I have to ask, what is your ambient room air temperature? Mine is usually around 72-80F, or 24-27C (been using the air conditioner a lot this summer, LOL).

You are obviously not from the UK then? The only thing I have been using mine for is heating

Fans on these VGAs will spin faster (up to 100%) if this F3 bios will be used. As the result the temperature could be decreased.
Please read the procedure of VGA BIOS upgrade using @BIOS.

[DiKey]

When this BIOS will be official? I do not want to lose garantie.
Sorry for my bad English.

[Dark Mantis]

I think that the update is official already.
