I am using the Maxi-jet one, 1000lph (265gph), with 3/8" ID tubing. Now my blocks are quite restrictive but I get about 100lph when the system is all together.
They are quieter then I thought they would be, and I am running it inline, and have not gotten a leak yet.
I do would have thought I would have gotten better flow. I am gonna be using my second one of these in a 1/2" system so hopefully I will get better flow.
Well I use the mini jet 108 ( gph) and with my window closed and oc'ed 500 mhz my max temps is ( at full load) 44c at med fan speed it will drop to 40ish at hight fan speed ( dont like the noise tho) so there ya go
