Crosstrack... my tubing diameter is ½" outer diameter and 3/8" inner diameter (clear vinyl tubing).
My system was built about 4 years ago, before anyone (that I know of) was going to ½" inner diameter tubing.
Ben... same block as I had previously posted plans for
here. Not even close to the designs here... simple cross drilled block. (agian, made 4 years ago)
Actually there are TWO of these in the system. One on my CPU and one on my GPU. So I am dealing with TWO sources of heat with one lowly 60 GPH pump.
I did get the 340 GPH pump... that was WAY too noisy and powerful. It would have blown my hoses off or at the very least annoyed the crap outta me. :shrug:
So, I think I will return it for a smaller pump... probably a 90 GPH or 185 GPH... the 90 has a max lift of 4.3 feet and the 185 GPH has a max lift of 4.0 feet. The 60 GPH I have has a max lift of 2.5 feet. The 90 would get me 1.5 times the flow I have now and the 185 would get me a hair over triple the flow. I still want quiet, so I will probably go with the 90 for now and if I have to change it later, I will.
Also, the 60 and the 340 are magnetic drive... the 90 is a direct drive. So I was wondering... are direct drive pumps quieter?
Last but not least, I had only partially lapped the P4 previously, so I finished the process last night and removed all the nickle plating. Only copper showing now... and the clamping force is still MAINLY in the corners of the IHS. I can see that the AS2 is forced thinner there and in the center it's slightly thicker... but it's so thin now I can see the copper color through it AND it's very uniform. (except where noted in the corners)
So far, it seems to be about 3 to 4 degrees C cooler. Again this is letting the system run overnight and observing the temp this morning before leaving for work.
We will see how the 90 GPH pump works out...
