Dont take this as rude, but -
"I can speak from my experience with my personal setup that pumps in paralell work just as good in terms of performance and redundancy as pumps in series."
Have you TRIED series yet? I dont think you have? So you CANT POSSIBLY speak from experience?
Ok, im going to go out on a limb here - You WILL RECIEVE better temperatures in series. Whether its measurable or not, is up to the accuracy of temperature sensors combined with how big a difference it makes. But, if you're happy with it, thats cool; its not hard to replumb a small section of your loop though, and wouldnt you like that 41 to be 39?
"I heard on the other forums that there are some really smart and nice people here, and not to discredit everyone, but i would like to add than none of us know everything. Please, in the future, try to be a little more considerate to others ideas and refrain from insulting peoples newly built systems which they put alot of planning, time, and money into."
"just heating up the water" wasnt an insult. Its like saying to someone 'you're running your 3200+ with ddr333 ram at 166 fsb, so all you've effectively brought is a 2500+' (yes, that was me, on another forum telling someone to buy ddr400 ram). Its a factual statement saying 'sure, the cpu works, but for it to work efficiently it should be at 200fsb'. Thats EXACTLY what the poster meant when he said that - what you have works, but its not the best way of doing it. To me, if you're gonna take these comments as insults, perhaps you havent been around here long enough, nor looked at these forums long enough to realise what a knowledge base there is. I'm going to suggest that you DIDN'T put as much planning in as you should have because if you did, you'd know that series > parallel in pumping terms. This isnt an insult - i was the same a while ago; finding
good information on the net isn't an easy thing to do. Put it this way -
Theres the flow for the pumps you have, the red is parallel.

And finally, pH's TDX nozzle review (Remember pH's cpu is only at 1.85v, 2350mhz)

More pressure = better cooling. Series adds head pressure.
If you're still not convinced, I give up.
Got to it first Gm - i have more tact :P!
