I have a project on my mind of making an external watercooling case (radiator, fans, tank and pump in one nice box). I will probably only use it at first for my P-III 700MHz, but I want to have plenty of headroom to run more than one computer in this loop (and if I ever get the money, an Athlon X2
). I will be using 1/2" 'ish piping, but my DIY P-III waterblock will probably be quite restrictive, and since I plan on running more than one, it should be a pretty restrictive loop. For the rest of the stuff, the radiator will probably be scavenged from a car wreckers place (I'm thinking 3x120mm fan sized), and the reservoir will be home-made (and hopefully watertight). Now that you know the context, here is the question:What pump should I use?
Due to supply and budget limitations there are only a few pumps that are suitable [price in CHFr.] (and what I've read about them so far):
-Eheim 1048 [60] (the standard pump, silent, but less powerful than 1250)
-Eheim 1250 [86] (twice as powerful as the 1048 on paper, but some say that only small (1-2°C) differences in real life, possibly noisy?)
-Eheim compact 1000 [37] (not much info at all about this pump, just a bit less powerfull than 1250 on paper, but same as 1048 in practice (according to http://www.tekforums.co.uk:81/lofiversi ... 29111.html), advantages are size, noise (same as 1048) and cost)
-Hydor L20 [30] (like an eheim 1048, with a less glorious reputation but cheaper)
It's possible, and probable that this information is incorrect. I'm currently thinking of going with the compact 1000. Another note is that size is not really a problem for me, and sound isn't really either, as long as it can deadened in another way (suspending, encasing in sound-damping material, etc..). My main consideration is price, and quality (longevity), I am not willing to pay 20fr. more for 1°C temp difference (who would?
).Thanks in advance for any advice, and I will keep this forum posted on my progress (although if might still be a while).
