GV-N560OC-1GI SLI Load Teperature very high

[halaween]

This is my first post as you can see, i am looking for help to maintain my GV-N560OC-1GI SLI cool.

First of all this is my setup:

ASUS Rampage III GENE (Micro ATX)
12 GB Kingston hyperx DDR3 1600
Intel I7 950
PSU ZALMAN ZM750-HP
Case is branded (acer) case (micro ATX) with one rear fan.

I know that my case is congested and i have very poor air circulation, ( i like small cases !!), any how the two GV-N560OC-1GI cards are like a sandwich they are very near to each other.

the first step i took to keep the cards little cool i flash GV-N560UD-1GI bios into my cards ( the clocks reduced to 822Mhz instead of 900 MHz) actually i select GV-N560UD-1GI because i feel that both cards layouts are similar and GV-N560UD-1GI has reference clocks ( i.e. i removed the overclocking from my original cards.

Still the load temperature is high (with 3dmark vantage i get 100c for the upper card and 90c for the lower one), other problem with BF3 the temperature is constantly 100c

Even in idle the fans are noisy and running at 50% at 41-43c

Bottom line i need some help to adjust the upper temperature limit to something like 85c so at that temperature the cards shall throttle down.

I am not happy with GIGABYTE own cooling solution for this cards as i am still feels that these cards are noisy. if there any solution to keep the fans at 40% at idle rather than using software this will be also good.

I appreciate any help in advance

Hi

Well you could try using Nibitor to edit the firmware to give you more control over the fan speeds. On the whole though I think it is all just down to your setup. If you must have a small case with few fans and a multi GPU solution then you are asking for trouble. I can't say I am surprised at the temperatures that you are reporting at all. Try adding more/better fans  or a bigger case where you have more space between the cards are your best bet.

Hi,
 
thank you for the quick reply.
 
for the first point i already tried using Nibitor but the application only offer the min-max fan speed limits, even i tried to reduce the min limit from 40% to 30% but i does not affect the idle speed of the fans, i think it is more related to the fan speed profile (temp VS RPM) and not the upper and lower limits.
 
you are right in regards to my system case i admit that i have problematic case for multi GPU setup, i am now thinking of reducing the performance of my GPUs by reducing the clocks (permanetly by Nibitor), i am woundering if that is going to reduce the load max temperature ?
 
Actualy i asked for a way to limit the maximum temperature from the card bios if possible, inspite of that may lead to lower performance

Please let me know if my approch is OK and any adise will be wellcomed

sorry for bad english

Hi

Yes if you do indeed decrease the maximum clock speed which will obviously have an impact on maximum performance and therefore heat ouput too.  The only thing is why run an SLI setup if you are going to start crippling it to slow it down to keep it cooler! Doesn't really make sense to me.

Hi,

Thank you for the reply, i decreased the clocks from 900/1800 gpu 4000 memory to 600/1200 gpu 3400 memory, but still i am getting 100c when i play BF3, with 3dmark vantage also 100c temp.

Most probably i will end up with one card with full capability instead of SLI

I think it makes more sense to use a single card in your situation rather then two cards and then cripple them so they are both only running at half speed. It wouldn't hurt to try it anyway just for testing purposes and see how it compares to the two cards with reuced performance.

Hi,
The single card GV-N560OC-1GI runs cooler at 70c maximum, however I have other question, i already tried flashing the GV-N560OC-1GI With GV-N560UD-1GI bios and the card runs without any problems except for the overheating issue with SLI setup, for me the both cards from hardware point of view are identical only the difference in clocks, I need to know what is harm if I keep GV-N560UD-1GI bios on GV-N560OC-1GI and if there is really difference in hardware.
It looks to me that gigabyte release GV-N560UD-1GI, as a rectification of the problems occurs with GV-N560OC-1GI.
Anyhow I put two (CF) HD 6850 and the system runs much cooler that with two (SLI) GTX 560 Ti (GV-N560OC-1GI)

The AMD Radeons do tend to run quite a bit cooler than the Nvidia cards which is one of the reasons I usually use them.

I can't say about the swapping/interchanging of firmware on the cards I'm afraid. None of us work for Gigabyte and therefore are not privvy to the type of information necessary to make that sort of judgement.  I would suggest contacting GGTS regarding it but I am fairly sure that I know what the answer would be. However try if you feel lucky!
