i am using Tt V2. my CPU is core 2 quad 6700 slightly overclocked @ 333MHz*10.
the room temp is above 30℃, the temp of cpu is 41℃ according to EVEREST Ultimate Edition. personally i think Tt V2 is very good.
By the way, i am a student living in the PRC(the People's Republic of China).i hope Tt V2 is available in your district.
forgive my spelling and grammar mistakes if there is any.
