I got and h 50 and it was hiting 65c on my 955 @ 3.8 1.55 v core 2600 NB at 1.45. So I mooded it
for a radator I uesed the condenser of a 12000 btu window uint that compruser was bad and the h50 one . For the pump I found a jabsco 12v.par max 3.5GPM. At a harwhere going out of business for 80. Load temps at stock speed and volts is 34 whit room temp at 68. At 3.8 @ 1.4125 temps are 39 after 8 hours prime 95. At 4 ghz @1.575 and 2.8nb at 1.5 I'm at 51. I checked my water temp it is at 74ish full load after 8 hours at idle its at room temp and my pump drins a 1 gal jug in under 25 seconds. So it is just the block can't keep up or is that ok load temps? Would changing the block out and going whit 3/8 tubing help? Whit high end water what does a x4 load at?
