Gpu's too close to each other and PSU

I have two GTX 760's and I was wondering if it's bad that they're too close to the psu, meaning right on top of each the psu fan is right below the gpu's fan?
 
Solution
Okay, the first thing I would do is run a graphic benchmark like Unigine Heaven (link below) and record the idle and peak GPU temps. The temps will show up in the upper right hand corner of the screen during the test. They'll be listed as GPU 1 and GPU 2 - make sure you keep track of which temps go with which GPU, as you'll want them for comparison purposes later.

Then power down, disconnect and remove the PSU. Flip it over so it's fan-down and reinstall it. Other than the cables, there should be four screws at the back of the case securing the PSU in place. The case and PSU are designed to work with the PSU in either orientation. That will allow the PSU to draw air from outside the case. There's a filter attached to the...
It'll work fine as long as you've got good airflow through your case. You may want to flip your PSU so it's fan down if your case is set up for it - that way the lower GPU and the PSU won't be competing for the same air, and your PSU will be able to draw cool air from outside the case.

Yeah, that's tight. You definitely want to flip that PSU if at all possible. . What case is that? How many of what kind of fans do you have, and in what configuration? Usually it's the top card that you have to worry about getting air to, but in your case both cards are going to need some special attention.

Edit: Might save some time if you just give us all of your build specs, i.e. CPU, CPU cooler, mobo, case, fans and fan config, number and type of drives, etc.

I just recently came back from being gone for three months, I'm pretty much a noob at this stuff so any help would be great.

The case and PSU are designed to work with the PSU in either orientation. That will allow the PSU to draw air from outside the case. There's a filter attached to the bottom of the case that you'll need to remember to clean periodically.

Once that's done, run the benchmark again and compare the temps with those from the first run. Usually whichever is the hottest of the two cards, as shown on the benchmark, is the upper card since the bottom one normally has better airflow. In your case, I'm not sure which one will run hotter, but when you run the second benchmark, you should see some difference.

Let us know what you're results are and we'll go from there. The peak temps from the second run should give us a good indicator for what, if anything, needs to be changed with your case fans.

Edit: It would also be useful to know the temp differential between benches run with your case fans set at low, medium and high.
 
Solution
There's a real easy solution to seeing if altering case ventilation will help:

1. Fun Furmark and record temps .... it should reach steady state by the time that curve reaches right side iof screen.

2. Take off side panel and grab a desk or window fan and blow air into the case. I use one of these.

3. If temps drop, additional case cooling will help.

Don't forget that cases sometimes provide fan mountings at the rear of HD cages. Side panel mounts are great also for your configuration as are bottom mounts.....

Other options include Antec Spot Cool and slot coolers.
