Cooling tips/advice for improving current setup

[revernd]

Hello

 

Long time reader first time poster.  I am looking for some tips on cooling to see if I can get this better or I am just dumb.  A new case (can use for another system) , adding a fan or replacing fans with something different are options (sound not a huge concern).  My current setup is 2 fractal r2 intakes, 1 fractal r2 top back exhaust, h90 at rear exhaust with push (stock fan) pull (fractal r2).  I am not using the fan controller but have all the fans on the motherboard.  When mining in a closed case I get 80-81 (84% fan speed) degrees on the gpu with around 35-40 on cpu and if i take off the side panel it goes down to around 76 degrees (73% fan speed) and 25-35 on the cpu but I have a small child who likes to touch things so not idea.  Running prime well mining CPU gets up 75 degrees and gpu stays around 80-82 but there is a lot of heat being exhausted out the back (not much at the top just been feeling with hand).  Attached is a picture of the setup.  Any tips or advice would be greatly appreciated.

the first thing i would do is flip the top fan as an intake if that doesn't work remove the front panel that should make temps a lot better the front panel in a lot of cases like mine http://www.amazon.com/NZXT-Technologies-Source-210-Black/dp/B005869A7K/ref=sr_1_2?ie=UTF8&qid=1391281578&sr=8-2&keywords=nzxt+source+210     restrict a lot of air flow. should have just gone with the arc midi IMO

The Fractal case fans are ok, If you want more air intake. I would have 3 intakes, 2 in the front and 1 on the bottom and then have 1 back exhaust and 1 top exhaust. Also if you haven't you should take out the top drive cages (don't know if you do since there is no picture) and if you have bad cable management clean it up and you should have more air flow into the case.

Sorry the "attach this file" button eluded me. Cable management isn't perfect but it isn't a mess and I do have the drive bays removed.   I've had the r4 for awhile and at the time was more concerned about sound than I was heat.  Since I started messing around with cryptocurrency's I have found myself more concerned with temps.

Yeah cable management isn't terrible. I would suggest getting another intake on the bottom.

I had an extra r2 fan laying around so I put it in as a bottom intake and rerouted the mess of cables in the hd cage.   Temps stayed the same and I also connected the rear exhaust, 2 front intakes to the fan controller to spin them at 1000rpm instead of the 750ish they were at with the motherboard which also didn't make any difference as well.
