What temperature should SLI GTX 570 be running at Idle/Loaded

This question must have been asked many times before, but from one PC to another this subject may vary between machines. First off, I have an ASUS P67 Sabertooth mobo, it has "thermal armor" which is supposed to avoid heat from affecting other components as well as vice versa. Of course this won't make a huge difference, but from what I have read it does make a few degree difference on the CPU in particular. There are only 2 PCIE slots on this mobo, and of course with the P67 boards they are limited to 8x slots rather than 16x. I have read that when gaming with say one monitor and with a average screen resolution, the PCIE slot speed does not make much of a difference (my screen resolution is 1920x1080). Is this true? As for my case, it's mid size, 1x 120mm front, 2x 120mm side fans blowing air in. 1x 120mm back, 1x 140mm top fans blowing out. My power supply sits at the bottom of the case with it's top fan blowing air up onto my second GTX570. My power supply guarantee's that it does not reach temperatures higher than 40c, hence the air blown up onto my second GPU shouldn't be hot.

When idle, ASUS AI Suite reads
PCIE-1: 34c
PCIE-2 30c
With EVGA OC Scanner
GPU1: 37c
GPU2: 44c

I find it curious that I get 2 very different readings from both software. However, when playing a graphic intensive game, example BF3, AI Suite gives readings of both cards within 40-50c range, where as EVGA OC Scanner reads 60-70c. What temperature should my cards be running at when idle, and when loaded? Also, why are these softwares giving off different readings. Does AI Suite only take into consideration the actual slot temperature?

Your temps are good for both idle and load.

I have three GTX 580's and right now I just looked at Evga precision and they were 28c . 29c, and 29c and I use water cooling. The game temps go 45c, 46c,46c. Do you have the Evga precision because that and the Asus AI have pretty much the same readings. I would go with the read out from the Evga software for the cards and the AI suite for the cpu and MB.

Yeah I have EVGA Precision, I overclocked my cards to the SuperClocked models frequencies. I know the temp would be somewhat lower if left at stock speed, but seeing there are some minor optimization issues with BF3 well I thought giving my cards a extra kick could do no harm for the moment. I think water cooling will be a future purchase, now with its costs having significantly dropped over the years. EVGA Precision and OC scanner also give me different readings. Example, I just woke my PC so temp will be slightly lower than usual.

AI Suite
PCIE1 - 30c
PCIE2- 27c
EVGA OC Scanner
GPU1 - 35c
GPU2 - 40c
EVGA Precision
GPU1 - 40c
GPU2 - 35c

It were as if OC scanner flips the cards around, and AI suite gives some way different reading...

1. The slot temperature and the GPU temperature are two different things

2. Try running OCCT's GPU test, that's what I use to determine temps.

3. As to x8 x8 versus x16 x16 the answer is yes and no. On average there is a 2-3% difference....some games actually slow down at x16 x16, some go down w/ AA off and up w/ AA on and some go up as much as 10% (i.e. STALKER)

Heh, @ 1920x1080 ultra settings, SLI gtx570 at 8x/8x has best performance. But from game to game I imagine this varies. I will try OCCT's GPU test and see what results I get.

Even though our attempts to make both platforms equal gives LGA 1366 an even greater bandwidth advantage, LGA 1155 still wins.


I had originally ordered a i7970, but when I started asking about ths i52500k and i72600k on these forums, people said HANDS DOWN i52500k for gaming, while the 2600k does offer somewhat a slighter performance boost (1-2%) for the extra 100$, they all said put it towards a better GPU, where we all know that's where the difference is made for gaming.

While the NF200 doesn’t completely solve the dearth of PCIe lanes available on LGA 1155 platforms, its ability to send identical data to multiple cards makes it perfect for SLI and CrossFire.


Does this mean the 2500k's GPU works on top of my GTX570's?
