Software monitor under Vista 64bit

Hello

Yesterday I bought new graphics card :

MSI GeForce 8800GTS OC 320MB DDRIII /320bit/ 2xDVI HDTV
[NX8800GTS-T2D320E-HD-OC]

After instaling this card in my system I discovered that there is no
software to monitor fan speed and temp (all included soft dosn't work
udner vista 64bit).

according to that I would like to kindly ask if anyone has some
knowlage if such software exist. Please send me name or link.

thank you in advance
regards
Gorgo
