I have vf900 on a x1900xtx and I hit 105C with ATItoll, no OC everything stock. Is it possible to have a broken heatpipe? The heatsink does not appear to get hot so something apparently is messing with the heat transfer. And before any one asks no, I dont have the temps from the stock heatsink, although I will probobly put it back on soon to check, thing is I have no extra thermal tape so once I take the ramsinks off I wont be able to put them back on. So is it possible to have defective heatpipes?
