I forgot to get all my temps before I added mine in.
But after an hour of LinX maxed out, VRM got to 34 or 35c max, no higher.
As for the board block, if you are running SLI and maybe another card, so the mobo heatsink is covered it can bet pretty warm. The heatsink works great with good air movement right on it, an air cooled system with solid air flow, but if yours is covered, like mine, cooling was soso. Water block on it it never leaves the 30s.
