Adding another GPU increase CPU temps?

[xD6N]

Currently using 1 780 Ti but am most likely going to be going SLI within next three months if all goes well. whilst playing games like Battlefield 4 my cpu temps average between 57-58 C occasionly they jump up to 65 C for a split second but they come straight back down again. My Cpu is an i7 4770k (Haswell, 4.2 ghz 1.210v) and is being cooled by a H100i my OC is completly stable too. any advice would be great.

It can if you have an open style coolers. If your H100i is exhausting then it's acting as exhuast fans as well (that was kind of redundant).

putting my hand above the case it does not feel to hot at all? is this ok? and if the temps do rise how will they be by?

It's hard to give a concrete answer on how much they will rise, but it's likely they will since one rear fan isn't enough to exhuast heat from two open style cooler 780tis, so naturally some of that hot air will pass through your H100i as well.

so maybe an average of 62 C after? i also really don't mind seetting my cpu back to stock seeing as there really doesn't seem to be any improvement.

You said in the other threads that your CPU rises to 65C occasionally? Let's say (hypothetically) It reaches 70C with another 780ti; that's still perfectly acceptable. I wouldn't hold back from buying another 780ti because of temperature concerns.

but to be on the safe side would you suggest that i run my cpu back to stock settings?

It wouldn't hurt to do that. See how hot your CPU gets @ stock with the second 780ti first, then OC your CPU accordingly.

there wouldnt be a bottleneck if my cpu were to run at 3.9 ghz would there with 2x780 Ti? and would it most likely be a 5-7 C increase in your CPU temp with two gpus? also my 780 ti runs at full load 65 C so having two cards really shouldnt be an issue im assuming.

Not at all. 4770k is more than capable of handling SLI 780ti.

 

CPU temps will likely raise (again, hard to say but lets use your guesstimate).

 

65C for a graphics card is very good, so no issues there.

 

This may seem like a downside to open style coolers, but they are so much quieter than the reference cooler, even at full fan speed.

so two 65 C graphics cards next to eachother, what kind of temps would they each get considering the heat of them being close to eachother?

Their temperatures might also increase, but not by very much. That's just the nature of open style coolers; the majority of the air they exhaust is inside the case, as appose to blower style which blows the air out the back of the case.

 

BTW, what case do you have?

i have antec p100 and my motherboard is http://www.overclockers.co.uk/showproduct.php?prodid=MB-571-AS will this be suitable for running two 780 ti's and keeping a GPU temp below 75 C? as long as i clock my cpu back to 3.9 ghz. thanks

That case reminds me A LOT of the R4. All will be good though, and I even doubt you'll have to keep your CPU at stock too.

sorry for late reply, thanks a lot for your help!
