A little extra cooling for the 560's

post #1 of 20
Thread Starter 
I got bored and added another fan right in front of my 560's. It sits perfectly on top of my HDD cage and with some double sided sticky tape, there's no worry of it moving or falling. Idle went from 31c/30c to 29c/27c and dropped a few degrees also while gaming. Only went through a couple benchmarks, but it was a quick and easy mod for a few degress.

Sorry for the crappy cell phone pics and dusty case lol. I was also thinking of taking the shrouds off the 560's and see if that drops temps also. During during they only get to about ~60c.

A huge shortcoming of the gtx 560 cooler is it exhaust most of the heat into your case, and SLI doubles that problem. As demonstrated by the OP, be prepared for this. (BTW, stating the obvious here...oh well).

Years ago with my SLI 7800gt I had to do that same sort of setup to control temps. I swore from that experience I'd never bother again with SLI nor with cards that don't exhaust most of their heat out of the case...but unfortunately at this point in time the 560 TFII is best card for all my other requirements (and thus dealing with noisy case fan setting once more, ugh). This is the only thing I miss about my retired gtx 275.

Yeah, I wish the cooler would exhaust the air to the rear. I might take the shroud off when I have free time next week. I heard it'll drop the temps a little bit

Considering how the GTX560 doesn't really have a blower fan in the same way the higher end products do, taking the shroud off may indeed help the temps if you have good air flow in your case.

As it is rightly pointed out that the two GTX560 Ti have (at least) half of their heat exhausted into the case via their front , I think the current approach is not optimal (as the added fan is just pushing these hot air back into the cards. The reason why the temp does not go up but drops a little is perhaps because this brute force approach also forces more ambient air into the cards...and those hot air will then have to travel down to the other end...further warming that end before escaping vai the rear).

I suggest 2 provisions:-
(1) devise a clear distinct escape path of this hot exhaust from the front of the two GTX560's

(2) provide more air through the side panel as this direction of entrance of fresh air is ideal to reach the 2 intake fans of the cards and at the same time does not interfere with the cards' hot exhaust.

For a more detailed explanation, please see my post #12:

Note: OP's ZEROTherm ZT-10D will have to re-oriented to point upward.

Yeah, I kinda figured it was forcing air through one side which is what I had intended. I'm no fan of a side fan though. This is just a temporary solution until I can upgrade to dual 570/580's with external exhaust.

Whoever isn't happy with their temps :
I never buy reference design for that reason.
Noisy and high temps.
Look at the Direct Cu II Overclocked at 900mhz 1.1 volt never above 60 degrees, idle at 30.
Note that is at 40% fan speed which I can't hear, I could crank it to 50 and get better temps.

  • cool story bro
  • most in this thread dont have reference cards, only the OP
  • notice the "s" for plural... SLI
  • also notice your awesome Direct Cu II Overclocked at 900mhz 1.1 volt never above 60 degrees, idle at 30 is a 3-slot card
  • SLI'ing 3-slot cards sucks
