The large tank pump has arrived from China but the other two pumps have been moving water with no loss for quite some time so I won't disturb the setup.  My two C1's are running at 37/39/37/38° & 36/40/38/40° so I like water cooling.  These board are the same as the S3+'s if I'm not mistaken but well cooled so capable of higher hashrate?  I'm running my C1's 243.75M/00675v/981GH/s for lower current on the line.  One S3+ is running at 42/39° and the other with a single board is 39°.  The one with the single board had started to heat up so I removed a cheesecloth filter dropping the temps down from mid-50° to the 40°'s but perhaps the damage had already been done.  The next day one of its boards had failed.  The higher temp meant higher current due to increased inefficiency and some damage occurred.  So, I like the water cooling.  I'd like to put water blocks in the S3+'s.
