Pre-TLDR: Is there a way to swap GPU 0 and GPU 1's designations?
I've got me a full sized PC crammed into a 1994 G3 iMac case mod (pics). I've got it running a 15" shit LCD and a 1080p TV. The most I really want out of it right now is run Starcraft II on Extreme settings, which it does, swimmingly, at 80FPS stable even on the instant build map (I brought it down to 50FPS though).
Problem is heat, no surprise, I was expecting it. The CPU was killing its stock heat sink so I slapped in a Corsair H90 watercooler and it's fantastic. I've got a stable OC of 4.8GHz on the FX-6300 pushing merely 60ºC peak.
The GPU's are a different story. The GPU in the back (GPU 1) only runs when Crossfire is enabled (fullscreen gaming) but gets great airflow. The GPU sandwiched between GPU 1 and the CPU's water cooler radiator and fan is the default GPU 0, and it likes to get into the >90ºC range especially when I overclock. These GPU's have had a previous life of slave labor so I know they get finicky around 95ºC and I don't like them in the high 80's. Both GPU's have a slight undervolt from when I did scrypt GPU mining on them, which should helps lower their temps a bit, but it only does so much with the shit airflow.
One thing that would greatly assist cooling would be to shift the primary load to the rear GPU 1. GPU 0, even in Crossfire takes most of the load. GPU 1 is always chilling out (literally) picking up what slack's left. GPU 1 gets much better airflow. I want to torture GPU 1 and have GPU 0 as my overflow. My last resort is getting another H90, a Kraken GPU adapter, and replacing the bottom case fans with another radiator but I'd hate to disassemble the whole thing and blow another hundred bucks when I could band-aid it by using the better-breathing GPU.
I can hook all the display connections to GPU 1 and I get no display til Windows loads, and IDK if it even shifts the load in Crossfire then. And I want access to BIOS without having to finagle connections. Yeah I could hook the TV up to GPU 1 and the 15" LCD up to GPU 0 but then Crossfire would be disabled.
Is there a way to swap GPU 0 and GPU 1's designations? I can't readily find anything via the Googles (maybe I'm just not searching the right terms) and nothing in the BIOS seems obvious.
