To me, it sounds as though you've potentially got a restriction somewhere, new radiators will help, but won't address the real issue. This is an issue i've experienced numerous times on Umbra (Sig rig), and it was always down to the same thing; crud buildup within the CPU block.

It also doesn't help that i run an old inefficient architecture (LGA775, QX6700), but it still suits my needs fine.

I'd run Furmark or Kombustor on my GPU if i were you, see what it reports. If it's abnormally high, then i'd wager there's something blocking the system.
Usually when the CPU is cooling off the GPU is sitting around the same temperatures, which is an increase from it's average idle temperature of around 37 celcius to around 42-45C.

When I run the system through Furmark, or a run on the Valley bench, the GPU heats up to around 55C at most, which isn't abnormally high, and I imagine cooler than what it would be with it's stock cooler.
