Oh yeah...
Max I'll have a mcw6000 and a MCW20 and some really low resistance radiators. Is it ok if I got the Mag2 instead of the Mag3? Some guy at the OCer forums said the Mag3 actually collapsed his 3/8" ID tygon (not really sure why that would happen since its a closed system ![]() |

nope
you guys don't understand the pressures in a closed loop the first 1/2 is positive, the second negative |

so if I do use thin walled 3/8" ID tubing am I in danger of having the tubing by the inlet collapse when using a high head pump like the mag3? |

My guess is he used thin wall tygon because its quite a bit cheaper. I cant see any of these pumps colapsing my 1/2 id 3/4 od tygon.

Since you said the first half has positive pressure and the second half has negative pressure Im guessing the highest postive pressure is right at the the outlet of the pump and highest negative is at the intlet. I am also guessing the pressure gradually changes. So it slowely goes from full positive, to less positive, to 0 to less negative, to full negative in the loop. I was already planning on using 1/2" ID 3/4" od or greater tubing on the inlet mostly because 3/8" just wouldnt fit.. how extreme is the change in negative pressure from the very tip of the inlet of the pump to 12" away of straight tubing? |

No one here talked about the Eheim 1250, i consider it a valuable silent pump, althought rather expensive.
I would guess the negative pressure would be equal trought all the first tubing on the inlet? (Assuming the pressure drop on the tubing is ignorable?)

Eh, same price at petsmart, physically bigger, and less head. Id consider it if it was substantially quieter. |

I have never tried a mag 3, so i dont know about quietness.
But Eheim is know for being a quality pump, quite an important feature in PC cooling. Dunno. I'll wait for replies.

It's the exact opposite of the outlet.
