All my GTX580 are without IHS and I benched 3D Mark 2011 at MOA ~1450MHz with 1.48v without any problem. Smoke and slamms did the same also without IHS... so I don't think there's a problem with IHS-less cards

P.S: After IHS removal, it's very important to put some nail polish or vaseline on the little SMDs that are near the core. Otherwise, when you will have some water there the GPU will DIE instantly
The Pot has perfect contact, no Armaflex around the GPU, just some Paper Towel. I'm sure it is no contact problem but I have no Idea what else it could be. GPU runs fine, even on air, and even up to 1300 MHz with the same Voltage scaling than before. Its like a Wall
