and it seems my temps have risen about 2-3c snce it started.

is anyone having any problem like this? i Bought the 1250 because of its reliability but i have yet to see where my spent cash has gotten me any of that..
 
got my 1250 in the other day and put a fitting in the top and cracked it :mad: . basicly i had to use a lot of epoxy to seal it up.

back on topic:

seems u have some air in your system.
 
ya its got a res. but it isint filled up allthe way ive ben waiting for the air to get out and then fill er up and cap it , but since the pump makes thesesounds at bootup i think im donna open the pump up and check it out when i put a new mobo in :)
ohya, u need fittings look at www.dtekcustoms.com
they provided me with everything i needed!
 
can you record the sound with some good microphone and tape recorder?? Or perhaps some digital cellphone.

Id be interrested in noises from eheims, since my 1250 doesnt make any any noise at all. (230V 50Hz)

All I hear is some spark engaging when I flick the switch and then a soft humm :D
 
My mag 3 makes a pop sound when you engage it, then I cant hear it anymore. The pop is the sound of power :D
 
My Eheim makes no noise, but it vibrates my aluminum case that makes it have a rattling noise:(
 
Pumps, unless they are leaking, cannot cavitate. You have too much air in your res.

I haven't heard a sound from the three eheim 1250 systems I've built since their fillings.
