CoolbiTs temp monitor

how acurate is it? i get pretty low temps for my overclock...45-50C load and am wondering if coolbits is reading lower then the actual temps...even though its got a nice copper heatsink and 2 fans on it.

im pretty sure coolbits is about as accurate as your gonna get, as i think it uses the temp-sensor built into the card (at least for later cards). But i could be wrong, not sure. I use it though, and it seems to be pretty accurate...
