Water pump heat
My system I have put together is very restricted in available space (Shuttle SFF), so was forced to pick a small pump. I chose the Hydor L20 running inline, and now I am finding I get very poor temperatures, no better than the stock air cooled heat pipe HSU.
After doing some testing out of the system with no CPU load, I find the pump is putting a lot of heat into the water, it is rising at least 10C above ambient in a very short time. So looking for a small pump that contributes very little heat, the CA-Sytems/DTEK looks interesting has anyone tried it yet? |

However dont be 100% sure the pump is the problem. |

Not sure what you mean by your comment though, with the pump being the only source of heat when tested, the water was heating very fast. What else can cause it ? |

Well all i relly mean is the rad is important aswell and you should not blame all your problems on the pump.
I will say tho that a 10C rise (short time? min or hours?) sounds like quite alot expecialy from a L20. However my experiance says that a L20 should not put alot of heat into the water and maybe the rising temp is attualy due to poor radiator design. |

Airflow through the rad is a far more important factor. The pump heat you mention should be almost irrelevant.

Were the radiator fans even on at the time when the 10C rise was witnessed?

Where was the temp measured, and how? If that temp is just at the inlet of the rad I would think you have a severe restriction. If it is system wide You either have poor airflow, air in the rad, MUCH too small a rad, or as you mentioned, some sort of large heat source adding heat. What rad & fan(s) do you have? How did you purge the system of air?

WTF does this have to do with water block design and construction?

If there is then I cannot see it, we come here to ask you guys who frequent a renowned forum for help, if this is the attitude of this forum then forget it. Admin, close this thread and delete my registration of this forum. I was 75% through writing a 16 page article to help others with lathe and milling information, but stuff you, its deleted already. Ask yourself this question JD, if Cathar or a few others had asked this, then you would never have wrote that reply. |

Dude you posted this in the WRONG forum. THIS FORUM is were it should have been posted. This site doesn't consist of just the Water block Design and Construction forum. There are other forums here to keep things somewhat organized so people can navigate easier. Who comes to a water block design forum to find info about pump heat? Damn I thought I had a short fuse. Chill out dude. :shrug: |

It's now in the right forum, and no, I don't read all the threads anymore just the important ones, and the silly ones that keep coming up over and over (like the "H2O as a TIM" thread ). If a thread's in the wrong forum, I just ignore it.
Reporting it would be step 1, that's right. In spite of appearances, the moderator(s) are actually active. As for Deadeye's original Q... cramping a system in a small case, is going to cost you something. Now you know what it is: performance. If you could increase the airflow (maybe a slim 120mm fan?!?), you'd get much better performance. |

On the other hand, don't discount what Jaydee116 has to say. He has a lot more experience doing this than 99% of the posers out there (i.e. he actually tries things out). |
