Did you find a solution?
I have a MSI GTX 465 Twin Frozr 2 and a PNY GTX 465 in SLI.
I recently installed a new SSD and since then the Twin Frozr card has been pushing 105C while gaming. The PNY is only getting to around 80C, which doesn't make any sense because the MSI has the better fan/heatsink.
Before the SSD installation, the MSI never went higher than 85C, maybe 90 on a hot day. I wonder if by removing the cards when I did the SSD installation, somehow that shifted the heatsink around a little bit? Does anyone have a youtube link on how to remove the fan/heatsink on the Twin Frozr and replace the thermal paste?
