680 SLI

[Xire]

Hi guys,

Thinking about adding another 680 to my rig but a little worried about overheating and potential bottlenecking.

My current rig is:

Intel® Core™i7-2600k
GTX 680
8GB ram
850w PSU
ASUS® P8P67 PRO

My processor will handle another GTX no problem right? I used to SLI two 480s with no watercooling and it got mad hot (old system) so a little concerned about having problems like this again. Does anyone SLI 680s with stock cooling?

Should not have any problems. I've run 3xGTX280,470,580,670,780 reference cooled and never had heat issue.

The cooling will be fine, but you might have a little bit of a bottleneck if you don't have your 2600k overclocked.

SLI 480's are a bad example as they are probably one of the warmest GPU's ever made.

I've got 2 stock 680s and they are fine temp wise, I've even overclocked them with no issues. My motherboard had a bit of space between the PCI-E slots though so the cards aren't right up against each other. Even if the slots are right next to each other then it will be fine, the top card will probably run slightly hotter but nothing to worry about.

Generally the stock blower designed coolers are much better for SLI then the coolers that dump heat into the case unless you have decent PCI-E spacing and a case with a side fan.

Overclock cpu to 4.5ghz+ to remove bottleneck, i got 2 reference 680s highest i see them go is 75c and that's on low case fans too in a warm room...usually about 70c max so should be fine.(you have to remember reference cooler on them is a lot better than the 480s)
