angry chimp indeed...thx for the tip D&T, just ordered from frozencpu:

Phobya Thermal Pad XT 120mm x 20mm x 0.5mm - 7W/mk (V-Regs, RAM, Ramplex, Koolance, MIPs, Innovatek) (19099)
Phobya Thermal Pad XT 120mm x 20mm x 1.0mm - 7W/mk (V-Regs, RAM, Ramplex, Koolance, MIPs, Innovatek) (19100)

I figure I'll use both thicknesses at some point as I split my remaining cards open and re-grease prior to the summer months.

Looks like I've got some time to polish up the GPUs  waiting for the USPS - thx rjk
