from looking at your sig i can see you already use a laing ddc1. here is a link to a howto to modify a ddc1 to a ddc2:

this can be done on a certain revision of ddc's. you have to verify if you have the correct one. looks like laing manufactures just one ddc and use a bridge to decide if it is a ddc1 or ddc2. just open up your ddc and solder in this bridge. now you can easy compare the two.
i did this mod and soldered a switch to my ddc. i can now switch between ddc1 and ddc2 modes. the difference is 3900rpm vs. 4500rpm and in my loop about 1.8liter/minute vs 2.25liter/minute which is a 25% increase in flowrate.
running at 4500rpm the ddc is noticeably louder but it's not that bad at all.
on the other hand, the increased flowrate does not much to my cooling performance. think i'm on the lower end of flowrate anyway. may be there would be a difference in cooling performance if i could up my flowrate to 4liters/minute ...
as there is no need for more cooling at the moment, i stick to the ddc1 mode for now.
