Hi Guys

I've just upgraded to a second 560Ti and just bothered about the heat from the first card when gaming, i know they can run hot but i would prefer if it ran a little cooler. I Have it at stock clocks but have seen people overclock these cards in sli and not have any issues. I don't consider my case to be bad at airflow and I can't move the cards any further apart.

My front fan is pulling air in the same as the two side fans and the cpu fan and top fan push air out.

Please could you advise.

Thank you in advance for your help
 
Apologies my sig isn't showing on first post, here are my PC specs

CPU: i7 2600k @ 4.6Ghz
Cooler: Corsair H50 w/ Antec Viper Fan
Motherboard: Asus P8Z68-V PRO/GEN3
Ram: 8GB Corsair xms3 @ 1600Mhz 9-9-9-24
GPU: 2x Msi GTX 560Ti Twin Frozer II (Stock Clock's) Sli
PSU: XFX 650w XXX Edition / 52a 12v Rail
HDD: 2x Corsair 60GB Force 3 in Raid 0 / 1x 500GB 1x 2TB
Case: Coolermaster Scout w/ 4x Antec Viper fans
 
Try flipping the side fans to extracting air also and have the intakes at the front of the case and see if that helps.
 
My top 580 was getting strangled in my old case due to the airflow being none existant from the front. Upgraded my case and the temps lowered into acceptable ranges for the type of card I have.

Off topic: your signature is too big buddy, we are allowed 4 lines max! Use a smaller font and put things side to side instead :P
 
:( just spent £550 on upgrades so a new case is kind of out of the question. and having my hdd's at the front restricts the air flow :( will stick my hand in and see what i can feel.

so in that respect i guess I can't do any more at the minute.

I'll alter my sig now, ty :)
 
This is a problem with non reference cooled cards, my gigabyte windforce 460's are the same. Whereas my reference cooled 470's run a bit cooler, due to the coolers exhausting out the pci brackets. The non reference cards dump the heat into the case.
 
I've just swapped the side case fans to pull air out but the cards run even hotter :( its just the top card has no where to push air apart from on the back of the other
 
Spotcool wont help an awful lot tbh, i have one behind my 470's. where it works very well. Tried it on my 460's, no difference at all. Sli works better with reference cards, but then the trade off is increased noise from the stock fans.
 
Imoh you are worrying about nothing if the top temps you are seeing on your cards are 81oC. Nothing wrong with that.

You could grab an exahust blower to put between them and you could set the top cards fan to work harder than the bottom one.
 
Thank guys, actually found a site for modding my case and i can make a few minor improvements to airflow. for the time being i removed the back plate in between the two card and it knocked off a few degrees :p
 
Hi Evo, I also have a 560 Ti Twin Frozr SLI setup.

I found removing the heat-sink and fans and replacing MSI's horrible thermal compound with Arctic MX-4 made a decent amount of difference, especially at full load. Idle temps were around 2-3 degrees lower and full load temps were 10-15 degrees lower. Also in an SLI setup GPU1 generally runs hotter than GPU2, so that's nothing to be concerned about.

Also the Twin Frozr's blast all their hot air out the back end of the card where your SSD's are mounted. For me I found the most efficient way of cooling was to have a fan sucking all the hot air out the front (Antec P182).

Hope I've been of some assistance

Temps seem fine to me though I would expect them to be a little lower with those vipers blowing on them. Perhaps try adding some more/better fans at the front.

However I saw a guy who had crossfired 6970's with the Twin Frozr cooler and he cable tied a 120mm fan onto the back of his case exhausting, which dragged heat away from the middle of the cards and reduced temps a hell of a lot, may be worth trying.

Yeah if the fans are on auto they'll run as fast as they need to, to keep the card cool. The Temps are acceptable, but you could take over and turn them up a bit further especially the one that's getting that bit hotter.
 
Use msi afterburner to tweak those fans i see your max fan speed hitting only 70%

faster sooner than later i say will keep your temps creeping up also u thought about water cooling

What do you mean by referenced and non referenced?
I'm looking to make a very similar build to the above mentioned, here: http://forums.overclockers.co.uk/showthread.php?t=18363877

but I need help with a case and PSU. Do you think i would have the same problem as evo? and is watercooling possible for the dual card setup you have?
