consider going parallel on the GPU's iso Serial
ie, all risk, more complicated, ZERO gain.
The configuration you use depends on your individual cooling system. A common misconception is that running parallel paths in the same loop is always better. Experimentation is usually suggested. Keep in mind that parallel lines reduce coolant pressure, so results will depend upon the pump and tubing configuration. In a serial system, only 2-3°C is typically added between video blocks.
To illustrate this point, let's say two video blocks are connected in series. The first video block is operating at 45°C, while the second is at 47°C. This is disturbing to some users. They want both video blocks at exactly the same temperature, so the blocks are reconnected in parallel. However, due to the pressure decrease of parallel paths and additional restrictions in the loop, both cards may now operate at 48°C.
yep if properly installed, dual gpu parallel and series will have indistinguishable temp differences. hence why suggest switching from one to the other?
I have measured it myself with calibrated thermocouples, as has other testers. What really ends up happening is... dual gpu in series has gpu temps of 45 and 46, and parallel has gpu temps of 45.5 and 45.5, though never see that until correct for water block contact and load differences since those exceed miniscule water temp differences between serial/parallel. And mathematically it isnt possible for them to be more than a degree difference with dual gpu/cpu unless one or the other is done poorly. Over 10 years I have seen many post about uneven flow problems with parallel loops (done incorrectly), serial is simpler.
Ok all, backplate is in my arms and is ready to get installed.
Anything else I should double check while I'm going to install and where should I drain? Should i get the fill port at top, tilt over case and empty water into a bowl?
