Hash rate and temperature

[afarzin]

I've noticed my miners (poclbm) don't report any changes as temperature swings between 70-85 (AC on or off) but the pool is logging as much as 100Mhashes/s more on average when temperature is below 70 degrees. Does this make sense?

Pool hashing speeds are not accurate. Only pay attention to the speeds the mining program tells you.

Mine rig has 80-90C temperature everytime...
