For the most part, the temperature of the water does not range over more than about 0.25C total difference between any two points in the system.

The pump before or after the waterblock only incurs the additional heat added by the pump itself, which for something like an Eheim 1250 means less than 0.02C added to the temperature of the water as it flows through it, and less for pumps like the Eheim 1048.

If you are noticing any variations with either setup, then this will be more liekly due to mounting variations and therm probe inaccuracy. Following the physics through, it is extremely unlikely that you will ever be able to detect a 0.02C difference with a 0.5C pseudo-accurate uncalibrated CPU diode.
