One of the reasons for this test this is I’ve recently moved all my radiators outside of the nouse to take advantage of the lower ambient temps and since the rads are out side I no long have to worry about fan noise so I can run my fans at 100% all the time. I have also added an extra radiator

I was expecting to get a 10 degrees C drop in temperatures but I hardly saw any gains. The logical cause of this was a reduction in flow rates due to the extra rad and 30meters of extra tubing

I plan to put a budget but powerful A/C pump in line to see how much difference this will make. Im also going to try a semi split loop. I will have my rad pumps pushing through the rads and around the 30m of tubing . I will then install a pump which rotates water around the chillier and water blocks. The two loops will then come together at a point to transfer the heart from each loop.

In the rad loop I should see an improvement In flow rates as I’ll be reducing the tubing and water blocks that these pumps need to pushed though.

The PC loop should see significant improvements in flow rates as there will be little restriction to flow.

Now I’ve considered doing a semi split loop before but the numbers have never made it viable. However in this case I think it might create better temps than if I had all the pumps in series (in line) with everything else. I think a split loop could work this time because of the significant reduction in flow around the extra tuning and radiators.

Well im going to test it and see
